The imaging of a full-color LED Screen is generally through files, videos, images, and text on the computer. Send to the sending card through the graphics card for trading. Then go to the receiving card to drive imaging. So how can we achieve the best display effect when we choose the LED Screen?
The picture quality of the LED Screen screen has a lot to do with the following factors. The brightness of the display screen, the width of the picture and the best viewing distance for installation, only if the various indicators meet the needs of the current use environment, then the display effect is the best. The display screen is composed of many subsystems, and we need to have a detailed understanding of each subsystem.
LED Screen imaging principle
It includes power supplies, video encoders and decoders, line drivers, digital signal processors (DSP), etc. These subsystems work closely together to produce video images. If you look closely at the LED Screen, you will see hundreds of individual video panels. A little closer, you will find that each panel contains 16X16 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 hundreds of thousands of LED lamp beads to generate video images.
LED Screen brightness requirements
The brightness of the LED Screen screen is not as bright as possible. In some environments, the brightness is too bright or too dark to give the best display effect. This requires that when purchasing an LED Screen, match the most suitable brightness according to the brightness of the application or automatically adjust it through the driver. Only in this way can it not only harm the eyes of the audience but also provide satisfactory image quality of the LED Screen.
These drivers have some features that help reduce the brightness of LED, such as dot correction (DC), pulse width modulation (PWM) dimming, and these brightness controls (BC). And these features all provide the same basic function that is to adjust the brightness of the LED, but their use is different. Understanding that the correct use of these features is the key to having the best quality video.
The best viewing angle of the LED Screen
Regarding the wide viewing angle and the best viewing distance of the LED Screen screen, it is necessary to perform standard measurement calculations on the use occasion before installation, calculate the required viewing angle and viewing distance, and then match according to this requirement, so that you can Ensure that the product meets the specific needs of the use occasion and present the most exciting and high-quality images to the audience.
