Domestic appliances are actually more influential abroad, such as refrigerators, washers, small appliances, etc. However, high-end refrigerators, dishwashers, water purifiers, etc. are dominated by Siemens, Smith, etc. Among black appliances, TVs are overshadowed by Sony, Samsung, etc. It has indeed been possible to break out of the country, but if it does not have a say in the high-end field, it means that it does not have enough influence in the industry, and the technical standards and specifications in the industry are determined by others. Therefore, to really stand out, you still need to have competent technology in high-end fields and advanced patents.
TV is an electrical appliance that can reflect technical strength in a deeper level among home appliances. Why do you say this? Because TV involves chips, displays, computing power and system application capabilities, and even communication technology, the Internet of Things and AI. In the field of high-end TVs, in addition to the quality, picture quality and parameter requirements of the TV, there are also higher requirements for picture analysis capabilities, light control capabilities, and real-time online video analysis. This article takes the Hisense U7G series as an example to talk about the technical status of domestic TVs in the global LCD TV field.
As we all know, Samsung and Sony are the leaders in high-end LCD TVs. Samsung’s chips, Sony’s optical display technology and color processing capabilities are the basis for their high-end dominance. Just like the iPhone 12 also uses 4GB of memory. version, still has unique features in performance and expression. Taking high-end TVs over 80 inches as an example, the low-end versions of Sony and Samsung are priced around 20,000. However, among domestic TVs, there are also products with self-developed chips and liquid crystal optical display technology: Hisense TVs. This article takes the Hisense U7G series, 85-inch LCD TV as an example: it introduces Hisense’s self-developed chips, self-developed ULED technology, and online Real-time analysis capabilities of live broadcasts and intelligent catalysis of motion pictures.
Take Sony as an example. Sony’s panel is XR100Hz, with the high end at 120Hz. It supports Terri Color display technology and eye protection functions such as reducing blue light radiation. The chip uses the Sony X1 chip and supports 4K HDR. The sensor supports the screen light changing according to the ambient light, stereo balanced speakers, etc.
Samsung LCD TVs at this price point also focus on HDR analysis of 4K video, with a refresh frequency of 60Hz. It uses a quantum dot processor, supports dual light source LED and multi-window modes, supports MEMC dynamic compensation, and voice interaction functions.
As can be seen from the above, Sony's main direction is still the screen, while Samsung's main direction is video processing. If you want to have both, the price may have to double. 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. It can support up to low frame rate 8K video decoding and can present 10Bit colors. The screen backlight processing uses ULED technology, which realizes 100-zone physical independent light control technology, 8*8 pixel color temperature equalization algorithm, as well as 2400 partition optimization and 120,000 block color brightness correction technology.
① Take watching sports events as an example. When everyone watches the "European Cup 2020" (the European Cup postponed for one year in 2021), the problems exposed by ordinary TV are: the competition environment is complex, Auditoriums, stadium lighting, etc. have high requirements for color contrast adjustment, and color distortion will occur when watching movies. Also, athletes are prone to smearing when running fast. When the picture jumps quickly or follows the rapid movement of athletes, there will be more jitter and distortion.
②Hisense ULED technology first uses 4096-level soft light control technology to control light in different light control areas, allowing the contrast to be controlled at a refined level. Supports smooth transition of 14-bit grayscale, supports strong picture contrast, and will not cause ghosting, burrs, etc. It supports 95DCI-P3 wide color gamut and performs secondary excitation of the high color gamut area, which is equivalent to color compensation. You must know that these display technologies are still the promotional points of some flagship phones.
③Hisense ULED TV can be used as an e-sports screen, with a 120Hz refresh rate screen, for playing large-scale stand-alone games. In addition to the shock of a large screen, it also has a strong visual impact. Hisense HDMI2.1 interface supports 4K/120FPS high-bandwidth video input. At the same time, to relieve GPU pressure, it can support VRR variable refresh rate, ensure the delay rate is less than 15ms, and support SDR/HDR/Dolby adaptive adjustment. In terms of system, it also supports automatic identification of game consoles.
④ Supports MEMC dynamic compensation. Through the AI ??algorithm, dynamically insert frames for fast moving pictures. Through the AI ??algorithm, within a millisecond-level response time, dynamically calculate the pictures in the smear picture, and then Insert pictures into live videos in the form of video frames to achieve automatic and dynamic compensation of motion pictures, making viewing clearer and smoother.
The memory and storage of Hisense ULED TV are 3GB and 32GB. Compared with high-end TVs at the same price, the configuration is at the upper-middle level. Of course, it also has Rheinland eye protection certification, Dolbit Atmos, DTS V-X, and camera equipment. In addition, Hisense’s higher-end LCD TVs also have 8K screens. Masterclass sound system and more.
Generally speaking, Hisense has taken a natural advantage in screens and integrated circuits with its self-developed chips and ULED technology. In addition to LCD TVs, it also has laser TVs that can compete with Samsung and Sony. Challenging strength. Even in laser TVs, there is more say. I believe that with more companies like Hisense, domestic appliances will occupy more market share in global high-end home appliances in the future.
