Who is the real king? LG E7 and Sony A1 comparison evaluation

With the continuous deepening of consumer upgrades, consumer demand for high-end TVs has become more diversified. OLED TVs have been recognized by industry experts as the king of the next-generation display technology because of their revolutionary inherent advantages such as self-luminous, thin body, and no trailing. This enables users to enjoy deeper depth of field effects and clear contrast between brightness and darkness. And more realistic color reproduction. Apple's latest release of the iPhone X also used OLED screens for the first time, and it also pushed OLED technology to a new height.

Two best-selling OLED TVs

Only a high level of OLED TV can bring a superior experience to users. However, there are many differences in core technologies, product design, and configuration among major TV manufacturers. Even if they use LG OLED panels, the viewing effects of OLED TVs are not the same. So, what kind of performance should a true high-level OLED TV have?

In the field of OLED, LG has the absolute right to speak. As the founder of OLED technology, LG is currently the only manufacturer that can produce large-size OLED screens, supplying OLED panels to more than 90% of mainstream TV manufacturers such as Sony, Skyworth, and Philips, bringing significant changes to the TV industry. Sony has always been known for its display effect, claiming that it owns a number of "black technologies" in the field of color TV, and has its own unique insights for digging out OLED picture quality. However, after entering the age of LCD panels, Sony did not have the core technology to produce panels. Instead, with the forward-looking nature of display technology, they chose to cooperate with LG Display and use LG OLED panels. This also shows that from the hardware point of view, LG OLED TVs use their own display technology to equip their own original screens, which has an advantage in product compatibility and technical processing.

So how does LG TV and LG's OLED TVs perform? Who can represent the highest level of OLED TVs? To verify the overall performance of LG and Sony's OLED TVs, we selected LG OLED E7 and Sony OLED A1. From the sound effects, picture quality, product design process and other aspects of a comprehensive comparison.

Why use LG E7 to compare with Sony A1?

LG is the first manufacturer to mass-produce large-size OLED screens in the world and has contributed to the development of the global OLED TV industry. At the same time, LG is also the first company in the world to launch curved OLED TVs, fully embodying its leading position in the OLED field. To date, a number of TVs equipped with OLED technology have been continuously introduced and continuously competed in international large-scale exhibitions with the top-level competitions of many internationally renowned brands. The flagship LG SINGNATURE W7 Sky MirrorTM wallpaper TV launched at CES 2017 has won dozens of awards for its panel thickness of only 2.57mm. The E7 is the most classic product of many LG OLED TVs, and it is highly recognized and praised by consumers. As a competitor, Sony is naturally not far behind. In early 2017, it also launched the first OLED TV, the Sony A1.

2017 LG OLED TV Products

With the same high-end OLED TV, LG E7 and Sony A1 have too much similarity, naturally, ultimately, let consumers compare. The first is the positioning of the product and the market price, followed by the panel of the product are using LG's OLED panel, and finally on the LG E7 and the Sony A1, we see too much "black technology." However, the comparison of many consumers is only based on these superficial parameters. Professional home appliance platforms have few and far-fetched contents for these two TVs. It is precisely because of these factors that we have determined that LG E7 and Sony A1 have the strength to represent OLED TVs at this stage and decided to compare the two TVs from the core technology, picture quality, sound effects, design process, etc. in all aspects for consumption. Provide more professional purchasing guidance.

Technical Comparison: LG E7 supports Dolby Vision/Dolby sound, Sony A1 technology lacks

Dolby Vision's Dolby Cinema with Dolby Panorama sound is the biggest selling point of LG E7 technology. The former can bring richer colors and more in-depth and natural details to the screen. The latter can give users a brand new listening experience. At present, many high-end cinemas and even Hollywood are using Dolby Vision and Dolby Panorama, allowing users to enjoy cinematic realistic sound field effects and impact while watching the movie.

Most high-end cinemas cover Dolby Vision and Dolby Panorama

In order to enhance the overall display effect of the screen, major TV manufacturers have started to promote HDR technology since 2016. Currently, HDR technology solutions can be roughly divided into Dolby Vision, HDR10, and HLG. They have different working principles and cannot support each other. TV manufacturers are more adopting the Dolby Vision and HDR10, while the same is the mainstream format. The biggest difference between the two is that Dolby Vision adds “dynamic metadata” to the data in addition to the core HDR image data. The brightness, contrast, color and other information for more accurate reading and rendering.

Color gamut, brightness information data

In the Dolby Vision format, "Dynamic metadata" is the scene conversion information that carries the scene conversion instructions and can be obtained from the video source. The Dolby Vision TV can better understand the brightness, contrast and color performance. . In contrast, HDR10 can only receive static metadata when playing content in this format. It cannot let the device know how each particular shot or scene changes. Therefore, HDR10 cannot continuously optimize the “picture currently being played”.

LG E7's own active HDR and "dynamic metadata" can be optimized scene-by-site, TV can show extremely realistic light effects, a variety of light and shade contrast, gradual change in light intensity or even halo performance are alive to achieve more natural Movie viewing experience. At the same time, it also supports one billion colorful features, so that the color transition is more natural, so more delicate in the details of the screen. It was precisely because of the more accurate control of Dolby Vision and Dolby's panoramic sound for picture quality and sound effects. LG was the first to have a strategic cooperation with Dolby in 2017 at CES. All OLED TVs support both. This technology, combined with its own outstanding OLED panel technology, provides users with exceptional quality picture quality, and the LG E7 is no exception.

LG OLED E7 picture quality and natural lifelike

Sony has always been a TV manufacturer with powerful image processing capabilities. In order to enhance the overall performance of the screen, the Sony A1 is equipped with an advanced version of the X1 image processing chip to repair and optimize image signals in terms of color, sharpness, and HDR. In particular, the LG OLED panel that is used can independently switch the self-illuminated pixels. When black is displayed, the relevant pixels can be turned off to display a more pure black color. After such adjustments, the brightness information is compressed on-the-fly, ensuring no details are lost under the HDR standard.

Can recognize the lighting effects of clothing, trees and fences in the distance and optimize the resynthesis signal separately

In principle, the Dolby Vision is the most advanced HDR solution at this stage. However, during our testing, we found that the Sony A1 cannot recognize and play HDR videos in Dolby Vision format whether it is connected to a USB device or an HDMI device. The hard-to-hard confrontation of the picture quality can only be grounded. In the field of HDR, Dolby Vision standards are more advanced. The reason why Sony has been emphasizing chip technology is mainly because the core technology of the panel is no longer in its hands, and chip technology can only be used as differentiation. In addition, Sony also recognized its own shortcomings and promised to add support for Dolby Vision in subsequent system updates, but it still appears to be a bad check. We will also continue to pay attention to it. Once the time is ripe, we will bring this summit to the broad masses of readers for the first time.

OLED panel: LG adjustment color accurate

As the basis of the quality comparison, the hard quality of the two TV OLED panels is also the key consideration for this comparative evaluation. In particular, under the premise that the panels of these two products are OLED panels provided by LG Display, how does the different adjustment style and color guidance of LG E7 and Sony A1 affect the quality of TV? The performance is rather curious!

First of all, science vocabulary volume refers to the color gamut range that television can display, and gamut coverage is the color gamut that covers a certain gamut standard. It can be seen that the two TVs show different color adjustment styles: Sony A1 has a higher gamut volume on the paper, but chose a conservative style of adjustment in the gamut coverage. The pursuit is A Japanese "natural", "frigid" wind color, and LG E7 in the palette must be more vivid, color gamut coverage is also higher than A1, the pursuit of quality is lifelike, gorgeous color style, which The style of the screen displayed in the objective contrasting link is also consistent.

Some people compare the picture of LG E7 with Sony A1 as the difference in color accuracy, but in fact, after testing, although the performance of the two products in color accuracy is very good, but the LG E7 color more accurate, gray gamma value Between 2.2-2.4.

The hardware used in this comparison was the Spyder 4 TV colorimeter. The test software was Display CAL 3.3.4 and Argyll CMS 1.9.2. Before the test, the screens of the two TVs were all adjusted to the default “standard” mode, with the highest brightness. At the same time, the two TVs were warmed up for more than half an hour. As a result of the test, the gamut volume/gamut coverage of the LG E7 is 140.2%/99.4% of the sRGB color gamut, respectively, compared to Sony's A1's gamut volume/gamut coverage of 152.3%/98.8%, respectively. . In fact, these values ​​are not much different, but the rich gamut volume, but not a good color coverage to achieve, there is no excessive benefit to the TV's color reproduction. The key is also who understands colors more thoroughly and can demonstrate the picture experience consumers want.

In addition to using the test data to illustrate the problem, we also added some screen shots to test the imaging capabilities of the LG E7 and the Sony A1.

In this link, we focus on testing the processing capabilities and color reproduction capabilities of the products in the shadows. After all, unlike traditional LCD TVs, the biggest advantages of OLED TVs are contrast and color reproduction. The test method is the same as described in the previous article. Before the test, the screens of both TVs are adjusted to the default “standard” mode, and the brightness is the highest. At the same time, the two TVs are turned on for more than half an hour for warm-up.

LG E7 outperforms Sony A1 in light and dark detail and sees more detail in shadows

The first set of comparison pictures is from the grayscale reduction test. Under the same test conditions, the LG E7 performed better than the Sony A1 in light and dark details, especially the pit changes on the surface of the earth and the slight changes in the intersection of black and white hue. LG E7 can capture all the details of the picture.

The second set of comparative pictures comes from the contrast test. Under the same test conditions, the LG E7 is also better than the Sony A1 for image processing. Focusing on the marked area in the figure, when the background light needs to be completely dark, the brightness of the LG E7 in the area frame is all "off", but the brightness of the Sony A1 in the area frame is still very bright. And the moon reflection that LG E7 presents is clearer, and the outside edge of Sony A1 reflection is very vague. Again, because Sony has not mastered the core technology of the panel, the effect on image processing is far less than that of LG.

The last set of comparative pictures also comes from the contrast test. In the same test environment, please pay attention to the red frame part of the picture. The details of LG E7 are the most prominent and you can see the details of the clouds in layers. In the real shot of the distant building, we can also clearly see a building in the distance on the LG E7, but the image on the Sony A1 becomes slightly blurred.

Through the above three sets of real shot maps, we found that in actual comparison, the LG E7 is better than the Sony A1 for control of the details of the shadows, and through the communication with the relevant technical personnel learned that the outstanding shadow details and LG on its television Product calibration and optimization are inseparable.

In the testing phase of the film source, we have selected several test videos of Ultra HD. This link is not only a consideration of the quality but also a consideration of the fluency of the local video playback. In actual tests, the response speed of the LG E7 is 21.1ms, and the response speed of the Sony A1 is 30.7ms. The LG E7 uses HDR's chip source input speed and game speed, and the speed of conversion of various pages is better than Sony A1.

The following set of pictures is the same group of pictures taken with our HDR10 film source. The left side is LG E7 and the right side is Sony A1. We can clearly feel that LG E7 has higher brightness and better color expression.

LG E7 bright colors and accurate / Sony A1 darker

LG E7 more accurate control of the three primary colors / Sony A1's three primary colors slightly biased

In addition, from the brightness of the screen, LG E7 is better than Sony A1. The brighter advantage of the screen is that even in a bright light environment, it will not affect the viewing results. For example, in the case of direct sunlight or strong lighting at night during the day, the contents of the screen display are still clear, the colors are still accurate, and the same image layering and color space are also greater.

Process design: LG E7 high-end stable

Faced with the low-end blocking of LCD TVs and the impact of smart phones on entertainment, how does OLED break in the mid-to-high end market? As the “only designated supplier” of OLED TVs on the market today, LG Display’s choice is “to exceed "TV" is intended to break the established perception of television, expand new usage scenarios for OLED TVs, and utilize the ultra-thin characteristics of OLED panels to allow OLED TVs to integrate more naturally into everyday home environments.

The guidance from the upstream poses even greater challenges for the TV manufacturers' designs. In this year's new OLED TVs, it can be clearly felt that every design excellence has been improved. So what are the characteristics of LG E7 and Sony A1 in process design?

Different from the previous years, TV pays attention to the luxury and styling of its own design. In 2017, major television manufacturers have chosen a narrow frame with a simple body shape, let the appearance of the TV fade out of the user's vision, let the visual center to return to the picture itself. Behind this change in aesthetic style is the rise of OLED TVs. As mentioned above, one of the advantages of OLED TVs is that they can make the products look more stylish and lighter in terms of process. In 2017, the first year of a frameless TV, the appearance of the LG E7 is not too much for the overall screen, and its advent is a symbol of the ultimate in frameless design. At the CES show earlier this year, LG E7 won the "Innovation Design Award."

LG E7 body thickness of 6.94mm, Note: This data covers the thickness of the glass backplane (test data for reference only)

LG E7 glass back plate thickness 3.59mm

Although the LG E7 and the Sony A1 are both OLED TVs, the two companies still have different understandings on how to use the thin and light OLED characteristics. We can see from the complete design of the product at a glance.

LG E7 on the screen design is very bold and highlights the thin and light characteristics of the OLED panel, and "crystal curtain phantom" design is quite eye-catching, the panel after the absorption of tempered glass backplane has strengthened the user's perception of OLED TV, quite " At the silent listening to thunder" feeling, the overall view, LG E7 like floating phantom floating, this TV uses a sound bar base, innovative combination of speakers and TV base, making the overall more atmospheric TV elegant. It should be emphasized that in the test of the thickness of the fuselage, the body thickness of the LG OLED TV E7 is 6.94mm, and the thickness of the glass backplane is 3.59mm, so the panel thickness of the LG OLED TV E7 should actually be 3.35mm (result only For reference), according to the author's understanding, this data is absolutely beyond the reach of the color TV industry.

Sony's design is more radical, A1's unique shape can display the screen more purely, and in order to echo with this kind of avant-garde design style, A1 chooses a robust design as a balance in the process, otherwise the whole The machine will look too frivolous. After the actual measurement, Sony A1's body thickness of 9.80mm (the results are for reference only), which not only far exceeds the thickness of the LG E7 6.94mm (results only for reference), even before their own "floating motion picture" LCD TV Have to be thick on many.

Sony A1 panel details close-up

In terms of design style, LG E7 from the consumer point of view, fully consider the needs of a variety of family units will be thin to the extreme, to maximize space-saving, machine thickness is only 19cm (the results are for reference only). Sony's original "A" shaped bracket design is eye-catching, but the extremely heavy weight base and tilted elevation angle screen make the thickness of the whole machine reach 35cm (for reference only), which has exceeded many The width of the TV cabinet means that before purchasing the A1, you will most likely need to buy a TV cabinet that is wide enough. Sony A1 was criticized for its elevation design, which was once considered a design flaw. The so-called elevation design means that there must be a certain viewing angle when viewing so that there will be no reflection phenomenon. And there is a high demand for the location of the product, because the TV needs to be placed low to ensure that the viewer will not be affected by the elevation angle. If there is no TV cabinet that needs to be wall mounted or the TV cabinet in the home is high, Sony A1's viewing experience will be affected.

The decoration habits of Chinese families, home sofas and televisions are basically horizontal, and few sofas are much more decorative than TVs, which is why 99.99% of TVs on the market are vertical. The reason why Sony will make a big fuss about the design of a product is actually very simple, mainly because it does not know the core technology of the panel. So much so that Sony A1's design gave people a feeling of cosmetic failure.

The comparison of the wall effect can also get a similar answer. Unlike the E7, the base can be wall mounted. Since the A1 is equipped with an integrated subwoofer on the back, the thickness of the wall is about 150mm, and users lose the significance of buying an ultra-thin TV. If users must choose wall hanging, they must leave more room for them, otherwise family members will cause obstacles during the move in the living room or bedroom. For comparison, the thickness of the LG E7 is about 89mm when it is wall mounted. Of course, not only the OLED camp, Quantum TV has tried to break through stereotyped LCD TV impressions in various ways this year, but due to the congenital deficiency of the panel structure, the similar design is only a simple and naive imitation.

Underneath the tempered glass back of the LG E7 is a sound bar base. All speakers are facing forward considering the user's viewing habits. The Sony A1 sounds through the screen. There is a subwoofer behind the screen. Whether it is a wall-mounted or desktop display, the subwoofer is facing the wall and the sound will be hindered by the corresponding refraction.

In addition, there is a small detail in the design, Sony A1's jack is in the bottom position, whether placed or wall mounted, users are very difficult to reach out to operate, but also a big drawback.

Overall, the wall-mounted LG E7 is slimmer, more stylish and space-saving. The viewing experience also focuses on the user's experience. It is suitable for all types of homes. In addition, when watching TV in a dark environment, the flickering of the mid-breathing light of the Sony A1 screen interferes with people’s attention and greatly reduces the viewing experience of the user. The LG E7 fully takes this into consideration and moves the design of the breathing lamp boldly. To the side of the TV, it can effectively eliminate all elements that can affect the screen rendering effect, maximizing the user's viewing experience.

Sound test: LG E7 more presence

The sound quality of TVs has long been neglected in the LCD era, but technology breakthroughs have also been achieved in today’s TV video quality competition. The new generation of audio solutions represented by Dolby’s panoramic sound technology can effectively cooperate with 4K HDR screens. A more realistic audiovisual experience.

Dolby Panorama sound surround sound through the sound bar, is the latest and most advanced audio technology. It breaks through the concept of 5.1 and 7.1 channels in the traditional sense. It can combine the content of the movie to create a more realistic and far-sounding sound effect. It can also add speakers to the ceiling to achieve surround sound effects and reveal more sound details. Improve the viewing experience of the audience. Currently LG's OLED TVs launched in 2017 all support Dolby Panorama sound technology, and Sony chose to temporarily not act on TV products.

Dolby Panorama sound adjusts the direction of the sound and greatly enhances the experience

Specific to the LG E7 and Sony A1 these two TVs, LG E7 can perfectly support Dolby panoramic sound, a TV can handle. Sony A1 does not currently support panoramic sound. Users want to experience a full range of Dolby's next-generation audiovisual experience. Only by purchasing the Sony soundbar alone can the user achieve this.

The LG E7 uses Dolby Surround audio technology, equipped with a professional Dolby stereo sound, breaking the traditional concept of sound channels, showing dynamic sound effects. Can also achieve intelligent sound adjustment, according to the different layout of the home environment, accurately test the audience position, adjust to the best sound effects, bring users a luxurious sound experience. At present, many high-end movies and Hollywood are Dolby panorama sound and audio technologies that are used to break through traditional sounds and detect sounds based on human movements and orientation.

LG E7 cavity speaker design more professional, sound full and full

LG E7 speaker detail close-up

In addition to the technology, the two TVs also have a distinct difference in audio configuration. LG E7 chose to configure a 60W, 4.2-channel forward speaker at the bottom to achieve Dolby panoramic sound, and Sony A1's so-called "screen sound field" technology has also attracted much attention at the beginning of its appearance. Sony A1 uses the simple features of the OLED panel mechanism to realize the image and sound are output synchronously from the OLED panel. Sony only needs to add 4 small resonance patches at the back. The effect that the user will see when the screen is sounding is actually the same as if the resonant sound is placed on the table. It is not that what is seen is sound through the screen, but the continuous vibration of the sound after the power on will not be on the screen. The influence of the service life is not yet certain for us. It is also a question worthy of exploration and consideration.

Resonance patch hidden behind Sony A1

Sony A1 subwoofer used to make up for bass defects

BOSS, Harman Kardon, or many other top-level professional audio companies are known for their stereo sound. The most expensive resonant sound system is seen on the Internet is seven or eight hundred yuan. This is actually a very common technology. . Resonance sound will be influenced by the material. If sound is emitted through the screen, it will lose the effect of true reduction, such as dialogue between two people, adding a glass in the middle. In addition, the Sony A1 uses a resonant patch and does not show bass effects. Even if a "wall-oriented" subwoofer is added, the bass part is still not enough.

Sony OLED TV A1 undergoes constant panel vibration model

Due to the difficulty of subjective quantification of sound effects, we selected several more representative tracks for the test. At the same time, several colleagues and ordinary consumers were invited to do blind tests. The test tracks are as follows: "The California Hotel" by the Eagles, "The Touch" by Maria Arredondo, "Drum Poetry" by Yan Xuemin, "The Ferry", "Forgotten Times" by TEACH, "1812 Overture" by TELARC, and "Batman Battle clips of Superman "Captain America 3". The constituency basically covers the bass, midrange, and high-frequency bands. The genre also includes pop, rock, symphony, and movie clips. You can feel the difference in the sound effects of the two TVs in all directions.

Compared to the two products, the sound experience of the LG E7 is more stylish and advanced, allowing users to have a stronger sense of presence. For example, an aircraft can pass through the screen and even if you close your eyes, you can know the trajectory of the aircraft. From the top of the head, this sound effect coupled with the front of the screen, may be the ultimate audio and video experience it. Dolby Atmos will call it Dolby Panorama because of its excellent sound field positioning. In addition, the Sony A1’s screen sounds novel, but the sound effects presented are far less impressive than those of LG E7’s sound from professional audio equipment. For consumers, the novelty is just a momentary experience, and the quality and long-term user experience is fundamental.

LG E7 can combine video content to present dynamic sound effects

Dolby Vision and Dolby Panorama are two of the biggest differences between the LG E7 and the Sony A1. Choosing high-end TVs, in addition to OLED technology, should look for Dolby Vision and Dolby Surround sound technology. After all, these two technologies can determine whether your TV is Dolby Cinema-like.

Cable design: LG E7 is simple and clear

After introducing the comparison of the two products in terms of picture quality, sound effects, and appearance aspects, let's take a look at their respective performance in product details. In terms of cable, all the cables of the LG E7 are placed behind the TV. The cable is simple and clear at a glance. The Sony A1 adopts the design of cable storage and integration. All cables are led out from under the bracket. Both cable ways have their own advantages and disadvantages. The LG E7 supports more compatible ports. Sony A1 pays more attention to the appearance of cleanliness.

The wiring on the back of the Sony A1 seems simple and hard to operate

Sony A1 seems to be very novel and simple design, all the connections in the middle of the TV backplane, seriously affecting the consumer experience, the most important thing is the inconvenient pluggable circuit; Second, Sony A1 U disk The interface design is too compact, and it is almost impossible to insert two wide-port USB disks at the same time. In contrast, whether the LG E7 is a plug-in line or a variety of port design, it is more convenient for consumers to operate.

Operating system: LG E7 smooth and humane

The LG E7 and Sony A1 are both built-in HUAWEI resources and have a wealth of content to meet everyday needs. The LG E7 is equipped with the latest webOS3.5 system, which utilizes a motion-sensing remote controller and a simple and intuitive webOS 3.5 quick launch bar to smoothly navigate through program content and easily acquire and enjoy your favorite entertainment content. The layout of the page, LG E7 is pursuing the viewing experience when consumers watch without interference, all the shortcut bar are below, when operating will not be affected.

Sony A1 equipped Android operating system, the interface layout is simple, although with Sohu Television, LeTV Sports, QQ music and other third-party suppliers, allowing users to have more TV entertainment options, but the convenience of operation is not as user-friendly as LG E7. For example, when it is necessary to exit the existing viewing page, the user needs to exit to the start page and enter again. In addition, the Andrews system often appears in the case of the card machine, the fluency of the product is not as good as LG E7.

Sony A1 needs to exit to the start page and re-enter

The LG E7's motion-sensing remote control is more stylish and user-friendly than the Sony A1's traditional remote control. When searching for content, the LG E7's motion-sensing remote control can be directly selected just like the mouse. The traditional remote control needs the direction key to operate back and forth. This difference is very obvious. For example, using a motion-sensing remote control to search for "movies" can take less than 10 seconds, but using Sony's arrow keys to search for "movies" takes more than 20 seconds.

In recent years, the VR market can be said to be a booming, 360-degree audio-visual effects, and people are immersed in the general enjoyment. Many people often like to shoot 360 VR videos when they are traveling. They are used to record bits and pieces of the journey. The LG E7 supports 360VR and real-time zoom capabilities. The panoramic photos taken can be played on the E7; zooming in real time, zooming in on the screen, watching more detailed things, watching some sports, etc. are all very good experiences.

OLED, high-end TV due posture

In recent years, TV display technology has been continuously introduced. OLEDs, quantum dots, laser televisions, and even future electro-luminescent “true quantum dots” and Micro-LED technologies are on the scene, constantly refreshing consumer awareness of television. . When time enters 2017, quantum dots have become quite weak and future technologies are far from timely. Sony, Panasonic, Philips and other manufacturers have joined the OLED TV camp one after another and have become the most powerful competitor of high-end TVs. It can be said that OLED has become the de facto mainstream technology for high-end televisions in 2017. It is worth mentioning that, at this year's IFA exhibition, Skyworth, Philips and other brands, with LG's OLED panel technology, show its style.

Through our investigation in the stores some time ago, more and more consumers have tended to choose OLED TVs when they change TVs. The reason is simple. They want to eliminate LCD TVs while being able to choose a brand new display. Technology "try it fresh." Behind this rejoicing result, it has contributed to LG's firm exploration of OLED for years.

After comparing and evaluating the LG E7 and Sony A1's flagship OLED TVs, we have seen the advantages of LG OLED TVs in terms of depth of field effects, brightness contrast, etc., combined with the adjustment of Dolby Vision and OLED panels, enabling users to bring Come to feel more realistic. Of course, while focusing on the quality experience, improvement and improvement of sound effects are also indispensable. The integration of many technologies ensures that the products will continue to be thin while still maintaining a strong effect. These have to be said to be a breakthrough.

Although the new OLED camp, we must also see the good intentions of Sony OLED A1, as well as its powerful chip decoding capabilities and continuous efforts to tap the OLED display effect, hoping to bring more possibilities to the development of the OLED TV industry.

For the majority of users, OLED TVs have a strong momentum of development and have already entered a large number of consumers. For the OLED industry, the entire color TV market has been upgraded again. The marketization of OLED TVs has come completely.
