The meaning of 4K and 8K in the small pixel pitch LED display
Case 2021-03-30

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


LED display manufacturers usually define 4K/8K by point-to-point splicing. Technically speaking, the 4K/8K of LED displays essentially refers to the physical (horizontal) resolution of high-definition pixels that can be achieved after splicing these displays rate. Within the scope of the existing screen, the mainstream 4K resolution (4K: resolution includes but not limited to 3840x2160) has 3840 pixels in the horizontal direction and 2160 pixels in the vertical direction. The multiplication of the two is the physical resolution we often say . 8K resolution is a strict ultra-high-definition resolution. Taking the typical 7680×4320 resolution of 8K UHD as an example, its horizontal and vertical pixels are twice that of 4K, and the total number of pixels can reach 4K screens. Times.


For ultra-high-definition small pixel pitch LED display, the smaller the dot pitch, the easier it is to meet the 4K and 8K full-HD resolution display requirements of the market display terminals. The display effect can also ensure that the audience will watch at close distances for a long time without graininess and visual Enjoy more comfort. With 5G commercial penetration into all walks of life, Dakco's produced 4K small pixel pitch LED display professional TV wall also meets 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. Selected by large-scale broadcasting studios in many provinces. Of course, in addition to the radio and television industry, the integrated applications of 5G+4K/8K/AR also target areas such as smart medical care, remote education, and command centers, because these places also require functions such as ultra-high-definition resolution, stability and reliability, and low latency.


Although 4K/8K LED displays have the advantages of professional-level picture LED  display effects, these devices need to support full HD picture output in addition to their own video sources. Relatively speaking, when playing 8K video sources, the display effect will be significantly better than 4K video sources. Although there are currently relatively few video sources matching 4K or even 8K resolution, as the increasingly mature 5G signal makes up for the pain point that 8K video itself needs to carry a huge amount of data transmission, the trend of terminal image display will inevitably move towards high-definition 4K or higher Even 8K, 5G+8K may become the mainstream application combination for large screens of 100 inches or more in the future.
