LED display with other items the same, in the course of the use will inevitably encounter a variety of problems. In the use of full-color led display, may be due to the following eight problems, resulting in difficulties or affect the use of large-screen, and also to extend its use period.
1.LED display cooling design, led when the work will be hot, when the temperature is too high will affect the speed of the attenuation and stability, so pcb board cooling design of the good and bad will affect the led display performance.
2.Design a reasonable current value: led the standard current is twenty milliamps, it is generally recommended in the use of the maximum current when the standard current can not exceed 80 percent, especially for the point spacing is very small large screen display Therefore, because the heat is not very good, it should be taken to reduce the current value of the measures. According to the study, as led display three colors led decay speed is not the same, you can target a color of the current value, to maintain a large screen for a long time the use of white balance consistency, thus extending the led display life The
3. Mixing lights: the same color and different brightness of the led lamp beads need to mix the lights, or in accordance with the discrete law designed to insert the lights to enter the lights, so you can ensure that each color brightness consistent. This process if there is a problem, there will be large-screen local brightness uneven situation, will directly affect the display led display.
