Full-color LED display is widely used in advertising media, traffic information, sports venues and so on with its large size, high brightness, strong environmental adaptability,with the improvement of LED chip technology, LED encapsulation technology, the LED display manufacturing technology and the drop of price, full-color LED display are going through the key period of price adjustment. Shenzhen Lehman photoelectric general manager Mantie li , when he talked about how to control and improve the quality of LED full-color display, he gave his ideas.

LED display device is the most key part. There are three reasons: first, LED is used widely in a full color machine. every square metre will use tens of thousands of LED . Secondly, LED decides the whole screen optical display performance., It affect the Audience's evaluation for display screens. Again, LED occupys the biggest proportion in the whole cost.

The choice of LED decide whole screen quality. If you can not choose good LED, other components cannot make up screen quality defects. Even though other components are very good.

Because LED has the angle. ...
... A full-color LED screen also has angle directional (full color led). When you see it in different direction, the brightness will be increasing or decreasing.even though display screen is good in the normal direction white balance. If LED Angle consistency is not good, white balance of the whole screen different point is also not good.

Because the driver output current has too far distances in the PCB board .it will make excessive transmission path pressure drop, It will affact the voltage of LED normal work.to make its brightness reduce. We often find that display module nearby LED luminance is lower than middle. It is the reason (wholesale LED lights). So we must ensure the consistency of the screen brightness. We should design good driver circuit distribution diagram.from: led bulb light
