LED Module Power Connector

LED module is also called as led tile, which name describes very well about its property - a very basic unit of the modular design, to "build" the giant size "led video wall". Generally, we can say one complete led screen system is composed by two parts - led display panel, and led display control system. LED display panel is actually the body of one led display system. And LED module is actually the most important part. If the led display has very good quality led module, with adopting a high class control system, this led display would show very good video and pictures; but if one led display has bad led modules, even you adopt the best control system, the video and picture shown on the led screen would be bad. In fact, no matter the control system, or the PSU, or any other device, we can easily replace them with a not too high cost. But if you want to replace all the led modules, it means no big difference from replacing the whole led display screen.

Generally, the Chinese led display manufacturers use 3 kinds power connectors in led module, please refer to below picture.

A and C kind power connector is usually for the clients who have the basic technical skill to fix electronic devices, because of the screws work you must do when you replace the broken led modules. B kind power connector is very widely adopted nowadays, we call it "VH4" type and the advantage is it doesn't require any tool to replace the led module, what you need to do is just plug out and plug in. But this kind power connector has several quality levels, if the spec adopted doesn't have good quality, the connector would be easy to loose.

And certainly, the power connector is very small part of the led module, it only determines if the led module could get a stable 5V power input. Regarding as the key points to determine the led module quality, we will gradually introduce some.
