Systems and methods are described for providing data to the multiple LED blocks of a LED display board. Each LED block can include an electrical connection or interface that has a reduced complexity compared with prior LED display boards. Six pins may be used for the connections between blocks - including a ground pin, an input/output (I/O) pin, two video link pins, and two communication link pins. Systems and methods are described for controlling the power supplied to LED block(s) of a LED display board. A power controller coordinates the supply of power to the LED blocks. The power controller controls the supply of power to selected groups of the blocks of a video board in a way to reduce the differences in peak instantaneous power supplied to sections of the display board or the entire display board itself, and thereby increase the useful service life of the power supply components. |
