In the past two or three years, the screen has been the most popular area in the smartphone industry. From only a few flagship phones using a 90Hz refresh rate screen, now the cost-effective machines with a prefix of 1 must be equipped with a 120Hz refresh rate screen as standard. Its replacement cycle is similar to that of the national 5G mobile phone.
Suddenly, like a spring breeze, the wind of high screen brushing is not only blowing over smartphones and monitors, but also in the field of TVs.
At the "Refresh Vision" Skyworth TV 2022 Spring New Product Tasting Conference Guangzhou Station, Skyworth Wallpaper TV Q53 series, Guardian G53 and e-sports quality master A33 were unveiled. The main line running through these products is "high refresh rate".
The Q53 series is positioned on a high-end side, and the target audience is the middle-class people who are pursuing the beauty of their homes. The core selling point is the split design of independent host + seamless wall: the screen part can be seamlessly attached to the wall, and the host part can be placed below. In addition, the acoustic system is also very good. The Q53 series is equipped with 14 acoustic units and 4 independent power amplifier chips, and the acoustic system reaches 80W of power. In addition, its peak brightness can reach 1000nits, the color gamut is 100% DCI-P3, and the color standard value △E has reached the broadcast-level monitor color standard of 0.95.
The positioning of the G53 series is slightly lower than that of the Q53 series, and the performance of audio and video and home aesthetics is slightly lower. Of course, the price will be lower, but the 120Hz high refresh screen, 120Hz decoding chip, and "full blood version" HDMI2 remain unchanged. .1 Interface.
The positioning of the A33 series is very clear: gaming TVs (e-sports-level picture quality masters). In the not-so-high price, Skyworth still plugged in the full-channel 120Hz, Dolby Vision and HDR10 support, 10bits color depth support, and the color accuracy ΔE=1 picture quality performance, which is enough to meet the latest PS5 and XBox Series X. host requirements.
Skyworth's tasting will remind me of the OnePlus 7 Pro released in May 2019. This mobile phone with a high refresh rate and high image quality screen as its main selling point has opened the arms race of the mobile phone industry screen, and at the same time cooperated with the chip With the improvement of performance, many games have begun to support 90fps or even 120fps mode. At the same time, platforms such as station B have also begun to support ultra-high-definition high-brush high-contrast video with 4K HDR 120fps frame rate.
If 4K HDR 120fps is a peak definition of the current picture quality of video game works, then many display devices are stuck at 120Hz display.
In the past 10 years or so, we have experienced the popularization of 4K and the popularization of HDR, so now, the high refresh rate of 120Hz has also become popular.
Although these parameters of 4K HDR 120Hz look simple, they are actually very complicated. Many years ago, we knew that HDR (High Dynamic Range) has different standards, HDR10, HDR10+, Dolby Vision, HDR Vivid, etc., the performance under different standards Worlds apart. Similarly, the 120Hz refresh rate is not marked to enjoy the 120fps picture.
For example, at the screen panel level, some low-end TVs will claim to support 120Hz, but they will often explain in small print that is not clear on the promotional page: The 120Hz of this TV is rendered by software from 60Hz to 120Hz. The translation is to realize the fake 120Hz on the premise of losing half of the picture quality through HSR, DLG and other technologies.
One of the things that has been making a lot of noise recently is the lack of details about the HDMI2.1 standard.
HDMI is a common video lossless transmission interface. Most of today's monitors and TVs are equipped with this interface. The HDMI 2.1 protocol interface supports 4K 120Hz, and the highest resolution can reach 10K. The previous generation HDMI 2.0 protocol interface supports 4K 60Hz. The HDMI Association has done a trick to cancel the HDMI 2.0 protocol interface, and now there is only one HDMI 2.1 protocol left, which means that display manufacturers apply to the association for product certification, even if the product does not support new features such as 4K 120Hz, it may be rejected. Certified as HDMI 2.1 interface.
Therefore, many products that claim to be equipped with HDMI2.1 interface are actually still using the old interface, which may not support 4K 120Hz, 10bit color depth and VRR variable refresh rate, and the transmission bandwidth is only 18Gbps, which is the so-called HDMI 2.1 TMDS; The full-blooded version of HDMI2.1 (HDMI2.1 FRL standard) supports 4K 120Hz and VRR variable refresh rate, and the transmission bandwidth reaches 48Gbps.
This is why Skyworth repeatedly emphasized that its interface is the full-blooded version of HDMI2.1 at the event, because only the full-blooded version of HDMI2.1 supports true 4K 120Hz.
At the same time, the ultra-high bit rate of true 4K 120fps video also puts forward certain requirements for decoding chips. Some old or low-end TV chips may not support 120Hz decoding.
To sum up, the screen, interface and chip all support 120Hz, then the TV can really be regarded as a 120Hz TV, and the card will not work anywhere. This is also the meaning of "full channel". When 120Hz content is played from a game console, U disk, or TV client, it must go through at least 2-3 thresholds, and a smooth way is "full channel".
This is a bit similar to the full link mentioned in the mobile phone market. Some mobile phone cameras support 10bit color depth, but the screen does not support it, so what users see on the screen is not 1 billion color photos. It supports 10bit color depth, but the color management is not done well. After the photos taken are converted, 16.7 million color photos are viewed on a 1 billion color screen.
For TV viewers, the characteristics of 4K 120Hz are all technologies that are "hard to use once used". In other words, it is a technology that does no harm without comparison. The upgrade trajectory of audio-visual technology is also probably going forward along this road, just as the laser IMAX movie is not just a big screen, but an all-round transcendence in color, resolution, brightness and sound effects.
But TV is different. Compared with the mobile phone, which can do everything by itself, and the movie screen can't do anything by itself, it needs external projection. TV is sometimes active and sometimes passive. In addition to the C position in the living room, it serves as the background board for the family to enjoy together; it is also the companion of the game console; it also bears the attention of mobile phone users: content such as the self-made documentary "A String of Life" at station B can only be obtained on the TV side. The best viewing experience.
The console game is another important meaning of the existence of the TV. Although it only undertakes the display task, most TVs often perform mediocre in this link. Taking the Xbox Series X/S as an example, there are now dozens of games that support 120fps frame rate, and even sporadic games support 4K 120fps, which is enough to show that some content has begun to touch the ceiling of TV hardware, and with the With the advancement of host hardware, game picture quality will eat up hardware performance again. As a device with a longer replacement cycle, TV can easily become a bottleneck.
It is against this background that the concept of gaming TVs with 4K/8K ultra-high-definition display screens, high refresh rates above 120Hz, low latency, and full-blooded HDMI2.1 interfaces came into being.
Looking back at this event, Skyworth clearly stated that the A33 series is strongly related to games and is considered a standard "game TV", but in fact, the higher-end G53 and Q53 series can also be classified as "game TV", of course. , the latter two TVs can also be labeled with more labels: home aesthetic TV and so on.
What remains unchanged is that full-channel 120Hz runs throughout the event, and high refresh rates are being popularized in the TV market from top to bottom.
