Technology | What is 4K, 8K LED display?

Nowadays, small-pitch LED screens are widely used in many fields that require professional display images, precisely because of their proud ultra-high-definition display technology. Relatively speaking, the pixel is the smallest display unit on the LED display. Improving the pixel value and resolution of the display device is one of the most direct ways to improve the clarity of the image output, which is also important for the restoration of image details and colors . The familiar 4K and 8K in the term "5G+4K/8K+AI" refer to the concept of pixels and resolution, so what is the difference between the two?

LED display manufacturers usually define 4K/8K by point-to-point stitching. Technically, the current 4K /8K of LED display essentially refers to the physical (horizontal) resolution of high-definition pixels that can be achieved by these display stitching. rate. In the existing screen range, the mainstream 4K resolution (4K: resolution includes but not limited to 3840x2160) The number of pixels is 3840 horizontally and 2160 vertically. The multiplication of the two is the physical resolution we often say. . The 8K resolution is regarded as the ultra-high definition resolution in a strict sense. Taking the typical resolution of 8680×4320 of 8K UHD as an example, its horizontal and vertical pixels are twice that of 4K, and the total number of pixels can reach 4 on a 4K screen. Times.

For the ultra-high-definition small-pitch LED display, the smaller the dot pitch, the easier it is to meet the display requirements of 4K and 8K full HD resolutions on the market display terminal. The display effect can also ensure that the audience can watch a long time without a grainy, visual Enjoy more comfort. With 5G commercial penetration into all walks of life, Sansi mass-produced 4K small-pitch LED professional TV walls also fit the surround visual experience required by ultra-high-definition display. It has the advantages of strong reliability, fast heat dissipation, quieter, and obvious energy saving. Large provinces and large radio and television studios are used. Of course, in addition to the radio and television industry, the integration of 5G+4K/8K/AR also refers to smart medical, remote education, command center and other fields, because these places also need ultra-high resolution, stable and reliable, low latency and other functions.

Although 4K/8K LED displays have the advantages of professional-level picture display, these devices need to support full HD picture output, and the source also needs to achieve full HD. Relatively speaking, when playing 8K video sources, the display effect will be significantly better than 4K video sources. Although there are relatively few video sources that match resolutions above 4K and even 8K, with the growing maturity of 5G signals to compensate for the pain point that 8K video itself needs to carry a signal device that transmits a huge amount of data, the trend of terminal image display will inevitably move toward high definition 4K and above Even 8K, in the future 5G+8K may become the mainstream application combination of large screens of more than 100 inches.
