  1、 Perspective

  The perspective of the LED display screen is determined by the perspective of the LED lamp beads. At present, most outdoor display screens use elliptical LEDs with a horizontal viewing angle of 100 ° and a straight viewing angle of 50 °, while indoor display screens use SMD LEDs with a horizontal and straight viewing angle of 120 °. There is a contradiction between perspective and brightness, and a large perspective will inevitably decrease brightness. The selection of perspective needs to be determined based on detailed usage.

  2、 Brightness

  The brightness of LED light sources is an important determinant of screen brightness. The higher the brightness of LED beads, the greater the margin of current utilization, which is beneficial for saving power and maintaining the stability of LED light sources. LED beads have different viewpoint values. When the brightness is confirmed, the smaller the luminous viewpoint, the brighter the LED diode. For display screens with different point distances and viewing distances, a balance should be found between brightness, viewing point, and price.

  3、 Loss of power

  Because the full color display screen consists of tens of thousands or even hundreds of thousands of sets of RGB LEDs, the failure of any color LED bead will affect the overall visual effect.

  4、 Antistatic ability

  LED beads are semiconductor components that are sensitive to static electricity and are prone to electrostatic failure. Therefore, their anti-static ability is crucial for the lifespan of the display screen.

  5、 Lifespan

  The theoretical lifespan of LED beads is 100000 hours, which is much longer than the lifespan of other components of LED display screens. Therefore, as long as the LED quality of the beads is guaranteed, the operating current is suitable, the PCB heat dissipation design is reasonable, and the production process of the display screen is rigorous, LED beads will be one of the most durable components in the entire display screen.
