Guide: Full-color LED display normally made by RGB LED. Best LED factory produce kinds of RGB LED with diferent size, like: 5mm RGB LED through-hole LED, 8mm RGB LEDthrough-hole LED, 3mm RGB LEDthrough-hole LED, 5050 RGB LED, 2835 RGB LED, 3535 RGB LED, 2727 RGB LED, 2020 RGB LED, 1010 RGB LED, 3528 RGB LED ect.

The following small series will introduce you how to identify the quality of the full-color LED display and how to maintain the full-color LED display. .
The quality of a full-color display can be signed from the following aspects:
1 flatness
The surface flatness of the full-color LED display should be within ±1mm to ensure that the displayed image is not distorted. Local protrusion or recession may cause the viewing angle of the display to appear dead angle.
2 brightness and viewing angle
The brightness of the indoor full-color LED display should be above 800cd/m2, and the brightness of the outdoor full-color LED display should be above 1500cd/m2 to ensure the normal operation of the full-color LED display. Otherwise, the brightness will be too low. Clear the image displayed. The size of the viewing angle directly determines the number of full-color LED display audiences, so the bigger the better.
3 white balance effect
The white balance effect is one of the most important indicators of a full-color LED display. In color theory, when the ratio of the three primary colors of red, green and blue is 1:4.6:0.16, pure white will be displayed. If there is a slight deviation in the actual ratio, the deviation of white balance will occur. Generally, it should be noted whether white is blue or yellow. Green phenomenon. The quality of the white balance is mainly determined by the control system of the LED display, and the lamp beads also have an effect on the color reproduction.
