4K is a popular keyword in recent years, and 4K display technology has attracted much attention. 4K LED display refers to a high-definition LED display with a pixel resolution of 3840×2100, and its resolution is 4 times that of a 2K LED display. At this resolution, the audience can clearly see every detail and close-up in the display screen, and make people feel immersive, bringing a different audio-visual feast to the audience. So, how can ordinary LED display screens achieve 4K high-definition LED display screens? First, improve the resolution of the LED display. The resolution factor is very important for display devices. Generally speaking, on the premise that the screen size is not much different, the higher the resolution means that the displayed picture is more delicate and clear, and the user's visual experience is stronger. When LED display manufacturers produce LED displays, they should focus on controlling product quality from raw materials, and constantly innovate product technology to improve the resolution of LED displays, so as to achieve the effect of high-definition LED displays. In the Rec.2020 standard, the aspect ratio of a single pixel is 1:1, and pixel addressing is performed in the order from left to right and top to bottom. ①Ultra HD 4K: horizontal resolution 3840, vertical resolution 2160, aspect ratio 16:9, total about 8.3 million pixels. ②Ultra HD 8K: horizontal resolution 7680, vertical resolution 4320, aspect ratio 16:9, The total is about 33.2 million pixels. In the current domestic LED display technology, there is no ultra-high-definition 8K LED display. Second, digital quantification. There are two types of quantization levels for UHD LED TVs: integer 10-bit and integer 12-bit, corresponding to UHD 4K and UHD 8K respectively. ① 10-bit: In the 10-bit binary number (corresponding to the decimal number 0~1023), the rated black bit is 64 and the rated peak value is 940; when the black bit overflows, use 4 to 63 for extension; when the peak overflows, use 941-1019 Carry out continuation; 0~3 and 1020~1023 are used as time reference numbers. The number of quantified colors is about 1.07 billion. ②12-bit: In the 12-bit binary number (corresponding to the decimal number 0~4095), the rated black level is 256 and the rated peak value is 3760; when the black level overflows, use 16~255 for extension; when the peak overflows, use 3761~4079 Carry out continuation; 0-15 and 4080-4095 are used as time reference numbers. The number of quantified colors is about 68.7 billion. Again, using the latest 4K display technology. 4K display technology can help improve the performance of LED display products. The brightness of the LED display will become higher, the colors will be more vivid, the contrast ratio will be higher, and the viewing angle will be wider and more comfortable. 4K display technology makes the LED display in the field of display products. The internal competitiveness becomes stronger. The LED display industry is currently conducting in-depth exploration and innovation for 4K display solutions. With the continuous development of LED display technology in the future, I believe that in the near future, the era of 8K LED display ultra-high-definition will also come, and everyone Bring a brand new display world, let us wait and see together!
