The concept of "smart micro-projection" is no longer unfamiliar to consumers. Compared with traditional display devices such as TVs and mobile phones, it has a natural advantage of being portable, non-screen, and large-screen. Since the 2015 LED intelligent micro-projection brightness has broken through 1000 lumens, the market has seen an explosive growth in the past two years. At present, the analysis indicates that the home intelligent micro-investment market will reach a scale of 10 billion in the future. In the past three years, traditional household appliance companies and emerging projection manufacturers have gathered in the field of smart microfinance, attracting huge amounts of capital, and people are looking forward to the prospect of “projectionâ€, even surpassing smartphones and televisions.

Seemingly hot smart micro-casting, in fact, tepid
However, behind the seeming prosperity, the smart micro-investment industry has gradually fallen into an awkward situation. According to authoritative media statistics, from January to July 2017, only 530,000 units of projectors were shipped online, including 430,000 units for home use and 1.9 million units for smart micro-investment (less than 1 kg). With hundreds of millions of shipments, the number of smart micro-investments is less than one percent, and it can only be described as two words!
In the final analysis, due to limitations of display technology, smart micro-projectors have been unable to increase their resolution as an important indicator. After years of development, most smart micro-projection resolutions have remained at 720P or 800P. In contrast, smart TV smartphones have reached the mainstream. 2K or even 4K ultra-clear resolution, the sharpness of the picture clarity is obvious, even if consumers have the desire to buy just stay in the wait-and-see phase, the only few 1080P smart micro-projection, the price of more than four or five thousand to make users unable to Sustainability seems to make the prophesy of the scale of 10 billion become a laughingstock.
Cool music as R4 dry goods, luxurious configuration inside and outside the repair
Cool music as the recent release of the new flagship model R4 series, almost immediately detonated the smart micro-investment market, what makes Cool music as R4 popular? Xiao Bian will take you with those "dry goods" of the R4 series.
Resolution
Projector resolution refers to the physical resolution of their core light engine. Simply put, it is how clear you can see that projection is actually an image made up of numerous small highlights. The higher the resolution, the more dots and the clearer the picture. Cool music as the new machine R4 chipset fully upgraded, with 1920 * 1080P physical resolution, resolution is 2.25 times the 720P smart micro-projection, even compared with high-definition LCD TV is almost the same!
brightness
In the past, the smart projectors were all RGB three-channel designs. The R4 adopts the innovative RGGB four-channel design. One more speed channel enhances the brightness of the screen by 30%. The 8A high-current high-density high-density LED light source and overcurrent drive technology increase the brightness by 70. %, giving it a brightness of 880 ANSI, it is more than a thousand lumens of visual brightness. At the same time, the lifetime of LED light sources is up to 20,000 hours, eliminating the trouble of frequent bulb replacement.
Glass lens
Many projectors use plastic optical lens lenses for cost savings. In addition to the high level of host integration and poor cooling systems, users may experience blurring of text on the screen during playback. This is annoyingly hot. Defocus phenomenon. Cool music as the R4 invited to the optical expert Ma Yongzhen, especially for the R4 to create a 7-spherical all-glass high-definition lens, coupled with all-metal precision milling tube and glass optical equipment, from the root to eliminate the thermal defocus, run coke, etc. phenomenon.
Image optimization
Cool Music has always been known for its visual effects in the field of smart micro-projection. With its absolute technology and R&D advantages, R4 has adopted up to 11 image optimizations on the screen, including HDR high dynamic range, ultra-clear noise reduction, dynamic addition of compression marks, Anti-mosquito noise, smooth zoom, suspension noise elimination, de-jittering, solution noise, cross-color elimination, color enhancement, contrast enhancement, projection screen effect is quite eye-catching. In particular, the application of HDR high dynamic range technology effectively increases the color range of the picture, enhances the dark contrast and emphasizes the level, and provides more image range and details, and the realism of the picture.
Hardware Configuration
Projector configuration requirements are also very high, R4 uses a new dual 64-bit Mstar nuclear intelligent system, with Mali 3D GPU, the screen rendering effect is very good, decoding 4K and other types of video smooth and comfortable. With 3G DDR4+16G large storage, the same core frequency speed is twice that of DDR3, providing strong support for the processor, the whole machine running smoothly than expected, no Caton phenomenon.
Speaker sound
Cool Music has made great changes in its own speakers, and the United States for the first time with the famous old speaker manufacturer AR, AR acoustic consultant Mark Treina especially for the R4 series to create a 10W two-channel discrete speaker, with 2 * 5W full frequency The speaker unit, DSP sound field processing technology, dynamic bass DBE enhancement technology, 360° Dolby surround sound and other special technologies, with the United States Ti chip audio driver, explosive force, comprehensive recovery of every note in the film, regardless of high school bass, are Can release the sound quality like nature.
In addition, the R4 series is also equipped with four-way trapezoidal correction, auto-focus precise focusing, 3D active shutter display and other technologies, with the light cool os system, the whole operation is very smooth, the user experience is quite good.
Cost-effective, cool music as R4 set off full HD popular storm
Cool LeTV has always been known for its outstanding cost-effectiveness. The 1080P R4 series launched in early December was not only equipped with luxury, but the price of less than 3,000 yuan pushed the R4 to the altar of “the most cost-effective smart micro-investmentâ€. It also laid a solid foundation and confidence for the popularity of Full HD.
Currently R4 series only launches R4 and R4S. In 2018, more series models will be introduced. It seems that this storm will continue to scratch!
