Four Important Indicators of LED Lamp Beads

As the most critical part of the full -color LED display, the quality of LED lamp beads plays a very important decision on the quality of the LED display. Generally speaking, LED lamp beads are used in the entire full -color LED display, and there may be thousands or even tens of thousands of LED lamp beads per square meter. Performance and color saturation and clarity.—The important indicators of LED lamp beads are: 1. LED display anti -static capacity. Because LED lamp beads are semiconductor devices, they are sensitive to static electricity and can easily cause static electricity. Therefore. Generally speaking, the failure voltage of the human static mode test of LED lamp beads should not be less than 2000V. 2. Full -color LED display attenuation characteristics LED lamp beads will slowly decay with the increase in use time. The attenuation of the brightness of LED lamp beads is related to LED chips, auxiliary materials, and packaging processes. Generally speaking, after the test of 1,000 hours and 20 mAh, the decay 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 in the future is great, and it will affect the display of the display of the display screen. 3. The full -color LED display efficiency LED display is composed of tens of thousands or even hundreds of thousands of groups of red, green, and blue. The loss of lamp beads will not be higher than one in 10,000 even if the lamp is aging for 72 hours. 4. The brightness of the brightness of the full color 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 larger the amount of the current of the current, which is good for saving power consumption and keeping LED lamp beads stable stability. LED lamp beads have different angle values. In the case of the brightness of the chip, the smaller the angle, the brighter the LED, but the smaller the viewing angle of the display screen. Generally, a 100-degree-110-degree LED lamp bead should be selected to ensure a full-color LED display.
