Method and device for driving a plurality of display devices

摘要

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.

主权项

1. A method of driving a plurality of liquid crystal display (LCD) modules each including an LCD device, the method comprising:
receiving a video clock signal that clocks a stream of RGB data provided in common to the plurality of LCD modules, wherein the RGB data comprises a plurality of video frames, each video frame further comprising a plurality of video lines; receiving one or more control signals indicating that each video line is to be divided among the plurality of LCD modules, such that each LCD module displays only RGB data for a corresponding portion of each video line; masking the video clock signal to generate a plurality of masked clock signals, each masked clock signal corresponding to one of the plurality of LCD modules and including a plurality of clock transitions corresponding to the RGB data for the corresponding portion of each video line to be displayed by the corresponding one of the LCD modules; and providing each of the masked signals to the corresponding one of the plurality of LCD modules.
