Abstract
A device includes a plurality of display modules configured to commonly receive a stream of video data from a controller and a video control masking unit. Each display module includes a display device. The video control masking unit receives one or more control signals that indicate how the video data is to be displayed by the display modules, and further receives at least one of: a clock signal for clocking the stream of video data that is provided in common to the plurality of display modules, and a data enable signal for enabling the display modules to process the video data; and in response thereto the video control masking unit masks at least one of the clock signal and the data enable signal to generate a plurality of masked signals each corresponding to one of the display modules, and provides each of the masked signals to the corresponding display module.
