When you were young, watching TV was the happiest thing in the world. The television set at that time was a square box that could emit light. It seemed like there was magic. It took away the soul of the people a little, and the whole beautiful world was shining in that box.
After more than 20 years, the style of television has already undergone earth-shaking changes. The square box of that year has become lighter, thinner, and clearer. It also has higher requirements for televisions, smart, 4K, curved surface, 3D, OLED... ... I want to find the best TV set and get back the joy of watching TV. The following is about TV sharing, I hope you and I can get the best TV for you.
Smart TV/box information can focus on smart TV information network sofa butler (http://), China's influential TV box and smart TV website, providing information, communication, TV boxes, smart TVs, smart TV software, etc. Answering questions.
First, television evolution - from mechanical to intelligent
China developed the first color TV set in 1970. This bulky box is my earliest childhood memory.
Early television was in the era of CRT tubes, and electrons were emitted from the screen to the screen and displayed again. The tube neck should not be too short, so the bigger the screen, the larger the TV volume must be.
â–² After the elementary school, the TV in the home has a big “assâ€
The LCD TV controls the state of the liquid crystal molecules through the electrodes on the display screen to achieve the purpose of display. Even if the screen is enlarged, there is no need to increase the size. So TVs can be made thinner and thinner, providing possibilities for wall mounting.
After entering the digital age, the TV began to receive digital signals through the set-top box. At this time, the television generally has two remote controllers, one television, and one set-top box.
Afterwards, smart TVs appeared. TVs, like mobile phones, can be installed with various APPs. In addition to watching television programs, they can also watch videos, shop, play games, and so on, completely changing people's lives.
â–² Use Fitness App on TV
In order to receive TV broadcast signals, smart TVs still need set-top boxes. However, in order to be able to connect network cables or WIFI, it is now an Internet set-top box.
Video resources mainly come from cooperation between television brands and major video sites. The competition in this area is very powerful. For example, a certain brand of TV can only install some cool but cannot install a fancy art... With the Internet set-top box, it can to a certain extent Can make up for these restrictions.
â–² Watch variety videos on TV
Second, the performance of television options
Just to buy a TV, we don't need to be an expert, but if we don't know all kinds of parameters and various technical terms at all, it's easy to be dug out of the pit.
1, picture quality
1 chip
The quality of the chip directly determines the performance and picture quality of the television. The main parameters are the CPU and the GPU.
The CPU is the CPU, and the parameters in the TV are expressed as Cortex A19, Cortex A53, Cortex A72, etc. Generally, the larger the number is, the better the GPU is. The GPU is the graphics processor, similar to the graphics card, and is used to enhance the picture dynamics. effect.
Currently, the mainstream chip manufacturers in the market include Mstar, Amlogic, and Intel. In addition to self-developed chips, the chips of domestic TV brands basically come from these companies.
In addition, the same television brand will use chips from different manufacturers in different series of products, which is one of the reasons why the television industry is relatively chaotic and complicated.
â–² Domestic brand Hisense
2 panel (screen)
Now all are LCD panels, subdivided into LCD, OLED, QLED, microLED and other types.
The LCD itself does not emit light and needs to increase the backlight source; OLEDs, QLEDs, and microLEDs are self-illuminating, and the picture quality is clearer than the LCD.
From a technical point of view, LCD technology has been very mature, and the cost is relatively low. It is currently the mainstream in the market; OLED technology is leading and basically mature, it can be said that it is the mainstream of the future, but at the current stage, the amount is still a bit expensive; QLED and microLED Still in its early stages, it hasn't become a big climate.
â–²OLED panel
LCD panels are mainly divided into VA soft screen and IPS hard screen, a simple difference between the method of placing samples in the store, the finger press the screen, if you can press the water ripple is VA soft screen, and vice versa is IPS hard screen. There is no difference between the two in the display effect, not too much entanglement.
Note that "LED TV" is not an OLED TV nor a QLED TV. Some merchants may claim that "LCD is not as good as LED." In fact, the two are completely unrelated concepts. LCD is a LCD panel for display, and LED is a light source device for lighting. The clerk is either not capable of doing business or is showing off people.
3 resolution
Now popular saying that 2K and 4K, 4K in the television field is 3840×2160 pixels, with high resolution and clearer picture quality. Now more and more 4K sources (it is said that the 2020 Tokyo Olympic Games provides 4K resolution signal broadcast ~), how to buy a new TV also depends on him in 5678, so choose 4K is correct.
Pay attention to avoiding "pseudo-4K" TVs and look for "RGBW" in product information. Some of them are pseudo 4K, because normal 4K TV pixels are arranged in "RGB" mode.
â–² Pixel arrangement of RGB and RGBW is different
4HDR
At first glance is not very familiar with? That's right, we often see HDR in cell phone cameras.
HDR means high dynamic range display technology. When used on a TV screen, the contrast between bright and dark images is enhanced, and the bright and dark brightness range is widened to make the picture more real and more layered.
Although the HDR film source is limited, HDR technology is still the main direction of the TV industry, because the visual experience is really much better than ordinary TV.
â–²4K+HDR TV screen effect
With respect to HDR technology, TV brands have different standards, such as HDR 10, Dolby Vision, HLG, and SL-HDR1. The first two are the most common, and HDR 10 supports 1 billion colors. Dolby Vision supports 68 billion colors, so Dolby Vision will be more realistic in color.
â–²Dolby Vision and HDR 10
5 panel physical refresh rate
The higher the panel's physical refresh rate, the less likely it is to blur the display of moving pictures and the smoother the picture. The mainstream panel refresh rate is 60Hz. It is usually enough to watch the drama and watch the live broadcast. The slightly better one is 120Hz. You can often consider watching the game and playing the game.
6 backlight mode
Mainly for LCD LCD screens, it is divided into straight-in backlight and side-entry backlight. In general, the direct backlight is better than the edge-type backlight because the backlight is more uniform; however, the edge-type backlight can make the screen thinner, and when the technology is strong enough, the edge-type backlight can also be uniform.
7 color gamut
Color gamut refers to the range of colors that the screen display can reach. The higher the color gamut, the brighter the displayed colors. TVs generally meet the NTSC color gamut 72% even if qualified, higher requirements can choose 90% to 110%, higher is not necessary, too strong colors will feel very unnatural, popularly speaking is "flash blinking."
8 Brightness
The human eye is most sensitive to the quality of the TV picture is the brightness information, the main parameter is the peak brightness, the average LCD TV peak brightness between 450-600nit, 4K, HDR TV's peak brightness average above 1000nit, Dolby Vision HDR TV's The peak brightness can reach 4000nit.
â–² Peak brightness of the Dolby Vision HDR (right)
9MEMC motion image stabilization technology
Also called speed drive technology. Ordinary LCD TVs may exhibit "ghosting" when presenting a certain moving picture. This is because the number of picture frames jumps too fast and the liquid crystal molecules are slow. Using MEMC technology can solve this problem.
103D
Most manufacturers do not produce 3D now, mainly because the current 3D viewing mode is very tasteless. First of all, there is a limit to the distance. 60-inch 3D has to be felt within 2 meters. Secondly, there are restrictions on the length of time to watch. To wear special 3D glasses, the time will be a bit longer and the eyes will feel uncomfortable. The glasses party will not say anything. How painful it is.
So now we don't need to think about 3D. We will wait for future holographic 3D technology to develop. Let's discuss it again.
11 Surface
Many people are asking which surfaces and planes are better? Undoubtedly, the curved surface will be better in visual experience because of the wide viewing angle, the more enveloping feeling of the picture, and the more comfortable look.
But the surface is also more expensive, the price of the surface will be about 1/3 more expensive than the same size plane, and the surface is not very suitable for wall hanging.
2, sound quality
In order to have a good sound quality, in addition to the configured speakers, there must be a good sound technology, namely DTS surround or Dolby surround. There is no absolute difference between built-in or external speakers, you must know to feel the scene. The main speaker brand on the market is the Harman Kardon speaker (currently acquired by Samsung).
3, intelligent system
Most smart TV systems are based on Android. Some big companies will bring their own systems. For example, Samsung uses the Tizen OS system, and LG uses the webos system.
What kind of system is a good system? Switching speed, simple interface, and rich video resources, domestic brands do better in this area.
4, memory and flash memory
Running the memory affects the running speed and fluency of the intelligent system. Try to purchase more than 2GB of in-house purchase. Flash memory has at least 8GB.
5, the interface
From the number of interfaces and interface performance, you can usually see the positioning of a TV. Today's smart TVs must have at least one HDMI 2.0 interface (supporting high-definition resource transfer such as 4K) and a USB 3.0 interface (which can quickly read video from the hard disk).
â–² HDMI 2.0 data cable
Third, the TV brand
1. Joint venture brand
1 Sony
Sony has almost completely occupied more than 10,000 yuan and 65 inches above the high-end market. Sony's biggest advantage lies in its chip technology, ensuring its position as the king of picture quality.
Its high-end models, no matter what the configuration is top, the budget can be considered adequate; but the low-end models, the configuration is down, the price does not drop, the price is not very high.
â–² Sony Dafa is good!
2LG
LG's OLED technology leads the market in OLED panels with a market share of about 90%. The picture is very soft, with good contrast, color, and refresh rate.
The chips of LG TV are basically all from Intel. The panel is an IPS hard screen developed by the company. The speaker configuration is Harman Kardon. The overall configuration is well-balanced and the prices are not particularly alarming. Just like the good students recognized in the class at school, the results never come out of the top 5 but rarely the first... In short, LG has a large price/performance ratio in the high-end market. .
3 Samsung
Samsung has a complete industrial chain (after all, the national pillar), the overall advantages are obvious, and marketing packaging has always been very strong. Specific technology, the input delay is low, the screen light leakage control is very good, the panel indicators are OK, but some people responded, Samsung's screen color cast larger.
The JU series is mainly focused on 4K technology and its definition is very good. The high-end KS series has always been the mainstay of "quantum light technology" and "direct backlighting."
2, domestic brands
Traditional domestic brands include TCL, Hisense, Skyworth, Changhong, etc. It can be said that each has its own advantages, TCL panel is good, Hisense is engaged in laser television research, Skyworth digs deeper into the OLED market.
Just as compared to international big names, there is still a small gap between these chips, panels and technical details.
3, Internet brand
Storms, music, millet, micro whale, Thunderbird, etc. are all emerging Internet TV brands. At the same price point, the configuration of these brands is better than that of traditional brands, and the cost performance is higher. Because Internet TV is mostly sold at card cost, mainly because it is profitable on content resources and advertisements, it is necessary to prepare for the purchase of Internet TV.
Of course, the core technology that traditional brands have accumulated for so many years is not covered. Therefore, on the high-end models, the gap between the quality of Internet TV, joint venture brands and traditional domestic brands is obvious.
Fourth, what are the main reasons to buy a TV?
It's always clear what your budget is before you buy something, and then you look at what you need.
If the budget is more than 8,000 yuan, it is recommended that Sony, LG, Samsung and other joint venture brands of the high-end models, the configuration is outstanding, the quality of the effect did not have to say, the perfect visual experience.
If the budget does not exceed 5,000 yuan, joint venture brands are not recommended, and the price/performance ratio is not high. Domestic brands such as TCL, Hisense, and internet brands such as millet and micro-whales can be considered, although the picture quality cannot reach the top level, and the system is easy to use, suitable for the people.
In terms of function, with the increasing number of 4K and HDR film sources, 4K and HDR TVs have become the mainstream in the market; if you like watching games and playing games, you must pay special attention to the refresh rate and motion stabilization. To know the true effect of these features, you can't just look at the parameters. It's best to experience it in a physical store.
In terms of size, the current mainstream of living room TV is 55 to 70 inches. However, if the living room is relatively small (for example, less than 20m2), don't buy too much, otherwise it will feel very crowded.

â–² 55-inch TV in the large living room effect
The bedroom TV is generally below 55 inches, but there are also friends who like to lie in bed and look at the big screen. It really will be very cool.
â–² 55-inch TV in the bedroom effect
In addition, the TV size is related to the viewing distance and resolution. Can refer to the following figure
Fifth, the installation of the TV
1, TV wall hanging
Since the birth of LCD flat-panel TVs, TV wall hangings have become popular, making the entire living room look simple and atmospheric, and the small-family favorites.
Wall-mounted TV for different decoration styles, put a few pictures to experience
â–²Simple and modern
â–² Fresh Nordic

â–² warm American
â–² Minimalism
In addition to aesthetics, TV wall can choose a suitable height, let people sit on the sofa, the line of sight and the TV parallel or slightly up, to get the most comfortable viewing position, save the day to play down the neck of the mobile phone ~
There are also drawbacks to wall hanging, such as most TV set-top boxes (some Internet TVs have built-in boxes). If you do not pre-embed a line in the wall behind the TV, the TV line will leak out, which is not beautiful.
In addition, the television is hung on the wall, and the gap between the wall and the wall becomes small, which is not conducive to heat dissipation, and indirectly affects the service life of the television. After wall hanging, it is no longer convenient to move the position.
2, wall installation steps
First, the wall surface is preferably a solid brick, concrete, etc., with a relatively strong mounting surface. If it is wood, hollow bricks and other weaker installation surface, to reinforce, support and other measures.
If you do not want to expose the TV line, you will need to embed PVC pipes during the hydropower reform phase, and later put all kinds of TV lines into the pipes. So be sure to determine the location and height of your TV wall in advance.
PVC pipes are generally 50mm in diameter and have a groove depth of about 70mm. The elbows connecting the pipes up and down are slightly larger to facilitate threading.
As a reminder, if the TV wall is a load-bearing wall, the slot should not be too deep and the PVC pipe can be replaced with a small pipe with a diameter of 15 to 25 mm.
The TV socket is usually reserved near the top of the PVC pipe. It can just be blocked by the TV in the late period, that is, when the TV is viewed from the front, the socket cannot be seen.
Finally, the television is fixed using a pylon that is divided into a fixed pylon and a hanging wall. Cantilever hangers are generally retractable and can adjust the orientation of the TV panel to achieve the desire to sit on the TV in any position in the room.

â–² Adjustable Angle Cantilever Rack
After the final installation is completed, remember to check it to see if the display is horizontal and if the TV can play normally.
Of course, there are also TVs directly on the cabinet. The flexibility is relatively high. The TV can be moved at any time; there will be enough space between the TV and the wall to facilitate heat dissipation; even if TV lines are not buried in the wall, the TV cabinet can The line was blocked by 7788, which did not have much visual impact.
