Television is the most profound embodiment of technical strength in household appliances. Why do you say that? Because TV involves chips, monitors, computing power, system application capabilities, and even communication technology, Internet of Things, and AI. In the field of high-end TV, in addition to the requirements of TV picture quality, picture quality and parameters, there are also high requirements for image analysis, light control and real-time analysis of online video. Taking Hisense U7G series as an example, this paper discusses the technical position of domestic TV in the global LCD TV field.
As we all know, Samsung and Sony are the leaders of high-end LCD TVs. Samsung's chips, Sony's optical display technology and color processing ability are the basis for their occupation of high-end. Just like the version of iPhone 12 that still uses 4GB of memory, it still has its own uniqueness in performance and expressiveness. Take the high-end TV over 80 inches as an example. The price of the low-end version of Sony Samsung is also around 20,000. However, in domestic TV, there is also a product with independent research and development chip and independent creation of LCD optical display technology: Hisense TV. Taking Hisense U7G series and 85-inch LCD TV as examples, this paper introduces the chip and ULED technology independently developed by Hisense, as well as the real-time analysis ability of online live broadcast and the intelligent catalysis of dynamic pictures.
Take Sony for example. Sony's panel is XR 100Hz, and the high-end is 120Hz, which supports Teli Charm Color Display Technology and reduces eye protection functions such as blue light radiation. The chip adopts Sony X 1 chip, which supports 4K HDR, and the sensor supports the change of screen light with ambient light, stereo balanced speakers and so on.
The price of Samsung LCD TV is also focused on HDR analysis of 4K video, and the refresh frequency is 60Hz. Adopt quantum dot processor, support dual light source LED and multi-window mode, support MEMC dynamic compensation, and voice interaction function.
As can be seen from the above, Sony's main direction is screen, and Samsung's main direction is video processing. If you want to have both, the price may have to double again. These features are all involved in Hisense U7G 85 inch.
Hisense U7G has a screen resolution of 4K and a screen refresh rate of 120Hz~ 144Hz. The chip is a U+ chip independently developed by Hisense, which can support low frame rate 8K video decoding with colors as high as 10Bit+. The screen backlight processing adopts ULED technology, and realizes 100 partition physical independent light control technology, 8*8 pixel color temperature equalization algorithm, 2400 partition optimization and 65438+200,000+block color brightness correction technology.
① Take watching sports events as an example. When people watch "European Cup 2020" (European Cup held in 2002 1 year delay1year), the problems exposed by ordinary TV are: the stadium environment is complex, the lighting in the auditorium and stadium requires high adjustment of color contrast, and color distortion will occur when watching movies. Also, athletes are prone to stains when they run fast. There is a lot of jitter and distortion when the picture jumps quickly or follows the athlete's fast movement.
(2) Hisense ULED technology controls different light control areas through 4096 soft light control technology for the first time, so that the contrast is controlled at a fine level. Support 14Bit gray level smooth transition, support strong contrast of the picture, and there will be no ghost and burr. Support 95%DCI-P3 wide color gamut, and secondary excitation in high color gamut area is equivalent to color compensation. You know, these display technologies are also some publicity points in flagship machine.
(3) Hisense ULED TV can be used as an e-sports screen with a refresh rate of 120Hz. Playing large-scale stand-alone games has a strong visual impact in addition to the shock of the big screen. Hisense's HDMI2. 1 interface supports high-bandwidth video input of 4K/ 120FPS. At the same time, in order to relieve the pressure of GPU, it supports VRR variable refresh rate, ensures the delay rate is lower than 15ms, and supports SDR/HDR/ Dolby adaptive adjustment. In terms of system, it also supports automatic recognition of game machines.
(4) Support MEMC dynamic compensation. The fast-moving picture is dynamically interpolated by AI algorithm, and the picture in the dragged picture is dynamically calculated within millisecond response time by AI algorithm, and then the picture is inserted into the broadcast video in the form of video interpolation, so as to realize automatic dynamic compensation of the moving picture and make the viewing clearer and smoother.
Hisense ULED TV is 3GB+32GB in memory and storage. Compared with the high-end TV at the same price, the configuration belongs to the upper-middle level. Of course, there are Rhine eye protection certification, Dubit panoramic sound, DTS V-X, camera equipment. In addition, in Hisense's higher-end LCD TV, there is also an 8K screen. The main sound system and so on.
On the whole, Hisense has a natural advantage in screens and integrated circuits with its self-developed chips and ULED technology. Besides LCD TV, it also has the strength to compete with Samsung Sony in laser tv. Even in laser tv, there are many voices. I believe that in the future, there will be more enterprises like Hisense to make domestic household appliances occupy more market share in the global high-end household appliances.
