How to play in the 8K era? Sharp definition of "8K ecology" with full blood resurrection

Sharp was once synonymous with Japan's innovation, and it's the best in the liquid crystal field. The corporate values ​​of "Building the King of LCD" support Sharp's passing through countless historical misfortunes, including the collapse of the Japanese bubble economy in the 1980s and 1990s and the Second World War in the 1930s and 1940s. Sharp has applied liquid crystal technology to a wide variety of electronic products and achieved many world firsts. From the first black-and-white TV in Japan, to the world’s first full-crystal computer and the world’s first ultra-thin electroluminescent film display.

Sharp's dedication to LCD technology is almost crazy. In the words of Vice President Mr. Shui Shuguang of Sharp Technology Development Co., Ltd.: Sharp's developers can always immerse themselves in LCD, from the first generation of computers, the second generation of TFT, and even The third generation of mobile terminals, Sharp LCD developers have always been associated with LCD.

In the history of the development of liquid crystal technology, Sharp has contributed a lot of technology worth remembering, and many of them are still difficult to be replaced and surpassed. Including IGZO technology, four-color technology, Huang Cai technology and X8-MEP professional image processing engine. This year, Sharp's first consumer-grade 8K TV is not only a concentrated outbreak of “black technology”, but also a guide and definition of the entire 8K industry under Foxconn.

The 8K TV has a resolution of 7680×4320 pixels, and it has 33 million pixels per frame, which is 4.3 times that of the human eye, 4 times that of the 4K display technology, and 16 times that of the ordinary HD technology. Watching an 8K blockbuster, each frame is clearer than the photo.

People's pursuit of screen resolution should be endless. For graphics calculations and displays, it can be said that how fast the CPU is is not too fast and how high the resolution is not too high. The user demand is exactly what exists. When the iPhone 4's Retina (960×640) retina display came out, people said that it was enough, and that the human eye was a different limit. But now a casual mobile phone is 1920×1080, Xplay 3S 2K, Xperia Z5 Premium 4K, higher-definition screen has “spoiled” our eyes, and it is impossible to return to the past.

Sharp 8K TV, in line with the definition of Super Hi-Vision technology, that is not only the resolution reached 8K, also has 120Hz refresh rate, 22.2 channel standard, 16:9 display ratio.

Sharp is the only TV company in the world that has no choice of OLEDs or Quantum Dots, and has been deeply cultivating LCD technology. This will inevitably compare Sharp 8K with OLEDs and quantum dots. However, the two are not the same, although they are all pursuing higher definition and better display effect, OLED and quantum dots are all display platforms, while 8K is a technology that can penetrate different platforms, 8K quantum dots, 8K OLED is the future direction.

Display technology pursues the limit and exceeds the extent of human eye recognition, just as human beings know the moon to know the depths of the universe. This is an inevitable trend.

Last year, Bill Lee Lynn directed by Li An adopted the standard of 120 frames/3D/4K for the first time. This set off a frenzy of technology for the film and television industry. Such a clear and high-speed capture brings a more immersive style. Experience. 4K is so, if 8K is a great challenge to the structure, description and performance of the film story, not only is it closer to the expression of the real world, but also provides more possibilities for the new expression.

Japan's well-known broadcast satellite operator B-SAT has sent new satellites to prepare for the transmission of high-definition 4K and 8K TV programs. It is reported that in December 2018, B-SAT will implement ultra-high definition television broadcasting. In December 2015, 4K TV broadcasting began in Japan.

At the Rio Olympic Games last year, Japan’s NHK TV station first attempted live broadcast of the 130-hour live broadcast in the 8K format. The current 8K signal has already begun to test the contents of the broadcast, including the concert of pop singer Takemura Tsutsuko and the opening ceremony of the 2012 London Olympics. The Japanese famous conductor Seiji Ozawa's Beethoven concert.

Japan’s NHK TV station also stated that at the time of the 2020 Tokyo Olympics, viewers can enjoy 4K and 8K live broadcasts. NHK TV station also demonstrated 8K technology at this year's Ceatec electronic fair, including a 120-inch 8K TV and 22.2 multi-channel home theater, the effect is very shocking.

At present, many game masterpieces have also added support for 8K resolutions, such as "GTA5", "Sorcerer 3", "Tomb Raider: Rise", "Far Cry: The Original Killing", etc. To 8K. However, in terms of current PC performance, TITAN Xp can hardly make an 8K gaming experience more than 30 frames.

If you want to promote 8K, it is not enough to light a screen, and it needs the support of the entire ecological chain. Specifically, it needs 8K vertical domain support, such as 8K video capture camera, 8K video encoding format and device, 8K video transmission broadband and interface, 8K video storage, decoding 8K chip, 8K display display device . It also requires extensive use of the 8K horizontal industry chain.

At the conference site, Sharp demonstrated to us the process of real-time recording and display of 8K video. After shooting the model with an 8K camera on site, Sharp processed the image on the AQUOS 8K TV in real time. After processing, the model's skin and clothing silk The lines, cuffs, tassels, all have made it.

In terms of shooting equipment, there are already cameras such as the JVC Super Hi-Vision that can record 8K videos. Sharp is also working with Japanese imaging equipment manufacturer ASTRODESIGN to reduce the weight of the 8K camera from 40kg to 5kg, so that it can be handled in the same way as an ordinary camera. Hand-held shooting is expected to come out at the end of 2017.

In the transmission interface, Sharp defied the AQUOS 8K TV to use a 4-way HDMI 2.0 interface to transmit 8K@120Hz video. In fact, superMHL interface can already support 120fps@8K data transmission. Compared to DisplayPort 1.3 which can also transmit 8K video, the latter's frame rate is still 60fps, while HDMI 2.0 still stays at 4K 60fps.

This interface technology is not only reflected in high-resolution, high-frame-rate playback, but also includes support for 48-bit color depth, HDR high dynamic range, superior sound quality, multi-screen display, and BT.2020 wide color gamut standard support These are essentially intended to ensure that images and sounds taken with high specifications can be restored to large-screen devices without loss.

In terms of wireless transmission, Sharp also announced that it will participate in the construction of Shenzhen 2017 annual major project - Foxconn Luhu Global Future Display Technology and Innovation Application R&D Center. Through the future application of 8K+5G in the base, R&D, 5G data download peak Speed ​​will be up to 20Gb/s.

The broadband and storage aspects of transmission are not as large as they are. Everyone may have heard that a 4K movie requires 300G and 8K is TB. In fact, 300G seeds are distributed using the CineForm encoder. This encoder is used to save project files when making movies. H.265 encoding technology can greatly increase the compression ratio of ultra-high definition video.

Some foreign video websites have already launched 4K video resources. For example, Netflix uses 15Mbps bit rate H2.65 encoding. Youtube uses 18Mbps bit rate VP9 encoding. The picture quality of this bit rate is very good, only slightly higher than the broadcast level. Poor, an ordinary movie (1.5~2 hours) is about 15G~20G. It can be imagined that if 8K video is played with 10 Mbps H.265 encoding or H.266 encoding with higher compression ratio, 8K storage and transmission are not so scary.

Resolution is just one of the expressions of 8K technology. Sharp's image quality and backlight technology are even more powerful for 8K. Sharp's new generation of color technology and direct backlight area control system developed by Sharp can display brilliant bright colors and deep dark colors. And fully compatible with Dolby Vision HDR imaging technology and BDA-HDR imaging technology, so that the TV can provide a higher dynamic, greater brightness of the image, with high-brightness direct backlight, automatically adjust, render the brightness of each frame, improve the contrast. In terms of color, a high ratio wide color gamut is achieved through a phosphor molecule process.

The construction of the 8K ecology is not an overnight success. Sharp has been working hard to promote the upgrading of the entire industry and has done a lot, but there are still many difficulties to be solved. Content is the biggest obstacle to the popularity of 8K technology.

Content and display terminals are always a chicken-egg relationship. Without content, the terminal is useless; without the terminal, the content can only be shelved. The content and the terminal are best in a synchronous development model, but unfortunately, the two do not belong to the same industry and cannot be made to move. If the life of a television is 10 years, all TVs will be upgraded once in 10 years. However, the content creation of TV is one-off, and it is impossible for an increasingly large TV program library to be upgraded as a whole. What we can expect is only incremental. Only new content can be produced with higher technical specifications.

What Sharp is doing is actively exploring 8K incremental content. For example, at the WBO Boxing Championship in the end of July, Sharp first tried to apply 8K technology to the sports industry, and the 8K ultra-high-definition display screen made viewers immerse themselves in the real picture of the details. At the launch and premiere party of "Vogue Film", "Past, Present, and Future" is a high-definition image that uses Sharp 8K technology to show the details of the softness of the dress, the exquisite details of the embroidery, and the details of the luxury jewels. Bring great visual impact.

At the conference, Yuan Xuezhi, Marketing Director of Foxconn Technology Group, also outlined Sharp 8K technology in terms of future work life, educational life, entertainment, family social life, green car life, property transaction procurement life, healthy living, and safe life. Blue map.

Of course, all this may not be so fast, but with Foxconn's manufacturing capabilities, all the vertical supply chain capabilities, coupled with the strong combination of Foxconn Sharp, will inevitably speed up the construction of this blueprint.

Summary: People's judgment standards for a good TV have never been fundamentally changed, and the visual experience is still the highest. The immersive film and television revolution and refined display methods have only just kicked off in the 8K era. Sharp's challenge is also a good opportunity, it just became the driving force of the entire 8K ecology. 8K era, wait and see.
