IT Home January 11 news, this afternoon, Hisense officially launched China's first fully self-developed 8K AI picture quality chip, fully covering 2K / 4K / 8K, 60Hz / 120Hz picture quality processing capabilities. This chip has been applied to the whole machine products, just finished CES2022, Hisense launched a MiniLED TV 85U9H equipped with a self-developed 8K picture quality chip.
The first self-designed 8K AI quality chip released today is the fifth generation of Hisense picture quality chip. According to the official introduction, this picture quality chip is the most integrated and feature-rich generation chip since Hisense developed the chip. Unlike some self-developed or purchased IP, all the technology of this picture quality chip comes from independent research and development.
IT Home learned that Hisense 8K AI chip uses Dual CPU, of which 2 core system control, 4 core image quality control, NPU to 1.2T Flops high-precision AI operation, in PQ, support full path 12bit, 444 perceptual clarity processing, color precision improvement, 8K120Hz motion clarity improvement, extreme contrast improvement.
Hisense's self-developed 8K AI quality chip supports 33 million + megapixel accurate reconstruction can smoothly and gradually raise the picture to 16bit, showing more details in the picture; through AI object detection, high-precision motion estimation compensation; in color control, by supporting 48-bit color depth; 7897 color point control, to achieve accurate color improvement, AI detection for faces can achieve skin color improvement. In terms of partition control, Hisense's 5th generation picture quality chip can support 26880 partition control, the contrast ratio is stronger, the dark part is more layered, and the future can also be adapted to ultra-multi-partition MiniLED products.
Hisense chip display said that the 8K AI picture quality chip released today is the fifth generation of Hisense picture quality chip, through 8K AI perception processing, it can be based on the user's visual focus for deep learning and picture quality processing, and the most sensitive clarity, contrast, color, motion fluency of human eye perception has reached the highest level in the industry.
For color improvement, the chip adds 2 color management modules and uses AI technology to detect the picture in real time (such as real-time detection of faces, and detection of scenes, etc.).
For different pictures, the most suitable color improvement strategy is adopted. For example, it will improve the skin color for the face scene and make the face more rosy; for natural scenes such as sunset, to improve the color saturation.
At the same time, the chip unprecedented support for 48-bit Color Depth (color depth), as well as 7168 + 729 control points to meet the high-precision color adjustment, to meet the accuracy requirements of professional-grade monitors, support 33 million + pixels of accurate reconstruction, easy to show the rich hidden details in the picture; by supporting 26880 partition backlight control, resulting in a 100000000:1 contrast ratio increase, bringing the ultimate contrast improvement, making the light and dark parts of the picture more layered.
In video viewing, consumers often encounter the problem of insufficient clarity and noise of online video. Hisense 8K AI quality chip is based on deep neural network to enhance the ultra-resolution of low-resolution images, which can achieve intelligent interpolation improvement for low-frame rate videos, implement high-fidelity restoration of poor image quality images, intelligent color grading of color images, and quality evaluation feedback for multi-distortion images.
Through a series of intelligent processing, the perception quality of the video source is greatly improved, and the adaptation of ultra-high-definition display devices is well realized, which greatly improves the visual experience of users and satisfies people's pursuit of beautiful visual perception.
At present, this chip has been applied to the whole machine products, and in the future, this chip will be used for flat-screen TVs, film and television-grade monitors, laser TVs, medical display equipment, etc.
Hisense TV 85U9H is an 8K TV with Mini-LED's new display technology. The 85U9H is equipped with Hisense's self-developed 8K picture quality chip, which applies Hisense's exclusive ULED full-array dynamic backlighting technology, with up to 4,000 partitions, peak brightness of 3,000 nits, and a refresh rate of 120Hz, achieving ultimate light control and accurate color reproduction, raising brightness, contrast and color to a new level, showing superior ultra-high-definition picture quality.
In terms of chip research and development, Hisense TV has launched four generations of ultra-high-definition picture quality processing chips and achieved mass production. The 8K ultra-high-definition image quality chip applied to 85U9H is the fifth generation of Hisense quality chip, which has achieved leapfrog development from 4K to 8K for the first time, and has benchmarking significance in chip design difficulty, functional diversity and industry leadership.
