Long led screen

Abstract

The invention provides a long strip LED screen. The screen comprises a control card and multiple unit plates. The unit plates comprise multiple first unit plates and multiple second unit plates. The first unit plates are connected to the control card in a first cascading manner so as to form at least one string of first unit plates. The second unit plates are connected to the control card in a second cascading manner so as to form at least one string of second unit plates. The cascading direction of the first cascading manner is opposite to that of the second cascading manner. The at least one string of first unit plates and the at least one string of second unit plates are spliced together into a long strip LED screen body. Thus, the on-load length of the control card of the long strip LED screen can be increased.
