Abstract
The display controller includes a decoder, a control circuit, and a video output logic circuit. The decoder is configured to decode a first display command and output a decoding signal and first synchronizing information indicating the first display command is received. The control circuit is configured to generate a first control signal based on second synchronizing information and the decoding signal. The second synchronizing information is output from a second display controller and indicates a second display command is received. The video output logic circuit is configured to send a part of video data stored in a video source and a plurality of first timing control signals for displaying the part of the video data on a display to the display based on the first control signal.
