What’s the 4K and 8K LED Screen?

Jul 31, 2020



Nowadays, small pixel pitch LED screens are widely used in many fields that require professional display images due to their proud ultra-high-definition display technology. Comparatively, 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 and effective way to improve the image output clarity, which is also important for display the details and colors of images. The 4K and 8K in the familiar "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 pixel-to-pixel splicing. Technically, the 4K/8K of LED displays essentially refers to the physical level resolution of high-definition pixels that can be achieved after splicing these displays. 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 called. while 8K resolution is ultra-high-definition resolution. Taking the 7680×4320 typical 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 4 times that of a 4K screen.


For ultra-high-definition small-pitch LED displays, the smaller the pixel pitch, the easier it is to meet resolution requirement of market display terminals the 4K and 8K full-HD. The display effect can also ensure that the audience will watch at close distances for a long time without the feeling of graininess, and have better visual enjoyment. Such as, Litestar's 4K small pixel pitch LED video wall, also meets the surround visual experience requirement of ultra-high-definition displays. It has the advantages of strong reliability, fast heat dissipation, quieter, and obvious energy saving. Selected by large-scale broadcasting studios in many countries.


4K/8K LED displays have the advantages of professional display effects. Apart from that those devices need to support full HD content output, content source is also required full HD. Relatively speaking, when playing 8K video sources, the display effect will be significantly better than 4K video sources. Although there are few video sources matching 4K or even 8K resolution, as the increasingly mature 5G signal makes up for the defect that 8K video needs to carry a huge amount of data transmission signal device, 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 larger in the future.
