Imaging principle and best viewing angle of LED display

The imaging of full-color LED display screen is generally through files, videos, images and words on the computer. Send to the sending card through the graphics card to process transcoding. Then drive imaging to the receiving card. So how can we achieve the best display when we choose LED display
The imaging of full-color LED display screen is generally through files, videos, images and words on the computer. Send to the sending card through the graphics card to process transcoding. Then drive imaging to the receiving card. So how can we achieve the best display effect when we choose LED display?
The picture quality of LED display screen is closely related to the following factors: the brightness of the display screen, the width of the picture and the best visual distance for installation. The display effect is the best if all indicators meet the needs of the current use environment. The display screen is composed of many subsystems. We need to have a detailed understanding of each subsystem.
Imaging principle of LED display screen
It includes power supply, video encoder and decoder, line driver, digital signal processor (DSP), etc. these subsystems work closely to produce video images. If you look closely at the LED display, you will see hundreds of individual video panels. A little closer, you will find that each panel contains 16×16 pixels. The anode of each LED is electrically connected to the output of an LED driver. Eventually, these tens of thousands of LED drivers will control the generation of video images through hundreds of thousands of LED beads.
LED display brightness requirements
The brightness of LED display screen is not the brighter the better. In some environments, the brightness is too bright or too dark, which can not give full play to the best display effect of the display screen. This requires that when purchasing LED display screen, the most suitable brightness should be matched according to the brightness of the application, or automatically adjusted by the driver. In this way, we can not only do no harm to the eyes of the audience, but also provide satisfactory LED display image quality.
Most high-end LED drivers provide designers with a variety of methods to control the LED current in their system.
Best viewing angle of LED display
For the wide viewing angle and the best visual distance of the LED display screen, it is necessary to carry out standard measurement and calculation for the use occasion before installation, calculate the required viewing angle and visual distance, and then match according to this requirement, so as to ensure that the product meets the specific needs of the use occasion and present the most wonderful and high-quality picture for the audience.
