led display clarity

The angle of the led display should deal with the problem of luminous flux consumption. The brightness and visibility angle of the indoor full-color screen must be above 800cd/m2, and the brightness of the outdoor full-color display must be above 1500cd/m2 to ensure the display’s performance Everything is working normally, otherwise the image of the displayed information will not be seen clearly due to the low brightness. The key to the size of the brightness is determined by the quality of the LED core tube.

There are many reasons for the uncontrollable definition of the display screen, among which the most critical reason is "LED failure." The main causes of LED failure can be divided into two levels: one is the poor quality of the LED itself; the other is the poor operation method. Based on the analysis, everyone sorted out the corresponding relationship between the LED failure mode and the two main causes.
