Full Color Rental LED Display Screens Connection Ways Pub Time : 2017-12-14 15:20:00
Full color LED display screens are connected by several LED panels, the connection ways and result will largely influence the visual effects of the whole full color rental LED display screens. This will not only influence the image quality on the LED screen, but also may cause them work abnormally. The followings are some commonly used connection ways to LED screens.
1. Overall cascade connection way. This is a normally used connection way, the full color rental LED display screens are connected with one electricity wire from the first LED panel to the last panel. When the whole full color LED screen is working, the electric circuit is same on each panel.
2. Overall parallel connection way. There are two kinds of overall parallel connection ways used for full color rental LED display screens: simple parallel connection way and independently matched parallel connection way. Simple parallel connection way connect the first and last LED panel with parallel connection way simply, the electrical voltage on each LED panel is equal when they are working. But the working reliability of this connection way is not high. Independently matched parallel connection way has better driving effect, completely protect each LED panel; if one panel have problem, it will not influence the other LED panel’s work.
3. Series-parallel connection way. This way combined the advantages of cascade connection way and parallel connection way together, make sure the full color rental LED display screens work more stable. One way is connect the LED panels with cascade connection way first, then connect them with parallel connection way; another way is connect the LED panels with parallel connection way first, then connect them with cascade connection way
4. Cross array connection way. This kind of connection way can also improve the working reliability of the full color rental LED display screens, and lower their failure rate.
