Many customers will directly look at the price when they look at the LED display, thinking that they are all LED displays, and there is no difference between the lamp beads. As a senior LED display manufacturer, LCF Group tells you that the quality of LED lamp beads is uneven, and the distance is far away. Not what you think is more important.


LED display manufacturers tell you that for full-color LED display, LED lamp bead is the most critical component, and the quality of LED lamp bead plays an important role in determining the quality of LED display. The brightness of the LED lamp bead determines the brightness of the full-color LED display. The higher the brightness of the LED lamp bead, the greater the margin of the current used, which is good for saving power consumption and maintaining the stability of the LED lamp bead. LED lamp beads 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, 100-110-degree LED lamp beads should be selected to ensure sufficient viewing angle of the full-color LED display.

The LED display is composed of tens of thousands or even hundreds of thousands of groups of red, green and blue LED lamp beads. Even if the lamp bead is aged for 72 hours, the failure rate will not be higher than 1/10,000. The brightness of LED lamp beads will gradually decay with the increase of use time. The decay speed of the brightness of LED lamp beads is related to the LED chip, auxiliary materials, and packaging process. Generally speaking, after 1000 hours, 20 mA lighting test at room temperature, the attenuation of red LED lamp beads should be less than 7%, and the attenuation of blue and green LED lamp beads should be less than 10%. The white balance of the full-color LED display will have a great impact in the future, which will affect the display fidelity of the display.

LED display manufacturer Liancheng issued a reminder: Since LED lamp beads are semiconductor devices, they are sensitive to static electricity and can easily lead to static electricity failure. Therefore, antistatic ability is very important to the life of LED display. Generally speaking, the failure voltage of the human body electrostatic mode test of LED lamp beads should not be lower than 2000V.
