Abstract
The disclosure provides a light cabinet, including multiple light boards and multiple light-board controllers. The light boards form a first light-board array of the light cabinet. The light-board controllers are arranged one-to-one on the light boards. The light-board controllers of the light boards in a first column of the first light-board array are connected in series to form a first controller string. The output terminal of the first controller string is connected electrically to an input terminal of a second controller string in a corresponding column of a second light-board array of another light cabinet. The input terminal of the first controller string is connected electrically to a first output terminal of a video data splitter (or an output terminal of a third controller string in a corresponding column of a third light-board array of yet another light cabinet).
