LED, as the most expensive and used component in LED display screen, is a very important part of LED display screen, so how does different LED beads affect the display screen? The influence of LED lamp beads on LED display is mainly shown in the following aspects:
1、 Brightness of display screen
LED brightness is an important determinant of display brightness. The higher the brightness of the LED, the greater the use margin of the current, which is conducive to saving power and maintaining the stability of the LED. LEDs have different angle values. When the brightness of the chip is fixed, the smaller the angle, the brighter the LED, but the smaller the viewing angle of the display. Generally, the LED display screen with a viewing angle of at least 100 degrees must be selected to ensure that the display screen has sufficient viewing angle.
For displays with different point distances and viewing distances, we should find a balance in brightness, angle and price.
2、 Viewing angle of display screen
The angle of view of LED display is determined by the angle of view of LED beads. At present, most outdoor LED displays use elliptical LED with a horizontal angle of 100 degrees and a vertical angle of 50 degrees, while indoor displays use SMDLED with a horizontal and vertical angle of 120 degrees.
Some high-level displays have higher requirements for vertical viewing angle. The angle of view and brightness are contradictory. A large angle of view will inevitably reduce the brightness. The choice of angle of view needs to be determined according to the specific purpose
