Nowadays, small-pitch LED screens are widely used in many fields that require professional display of images, precisely because of its proud ultra-high-definition display technology. Relatively speaking, the pixel point 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 plus 4K/8K plus 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 today's 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 76804320 resolution of 8K UHD as an example, its horizontal and vertical pixels are 2 times that of 4K, and the total number of pixels can reach 4K screens. Times.
For ultra-high-definition small-pitch LED displays, 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 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 the commercial penetration of 5G into all walks of life, Winbond's mass-produced 4K small-pitch LED professional video wall also meets the surround visual experience required by ultra-high-definition display, and 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 plus 4K/8K/AR also target areas such as smart medical care, distance education, and command centers, because these places also require functions such as ultra-high-definition resolution, stability and reliability, and low latency.
Obwohl 4K/8K-LED-Displays die Vorteile professioneller- Bildanzeigeeffekte bieten, müssen diese Geräte zusätzlich zu ihrer eigenen Full-HD-Bildausgabe auch Full-HD realisieren. Relativ gesehen ist der Anzeigeeffekt bei der Wiedergabe von 8K-Videoquellen deutlich besser als bei 4K-Videoquellen. Obwohl es derzeit relativ wenige Videoquellen gibt, die eine 4K- oder sogar 8K-Auflösung erreichen, da das immer ausgereiftere 5G-Signal den Schmerzpunkt ausgleicht, den 8K-Video selbst benötigt, um eine riesige Menge an Datenübertragung zu übertragen, wird der Trend der Terminalbildanzeige unvermeidlich sein in Richtung hochauflösender- 4K oder höher bewegen. Sogar 8K, in Zukunft könnten 5G plus 8K die Mainstream-Anwendungskombination für große Bildschirme von 100 Zoll oder mehr werden.
