Abstract:
1. A display controller, comprising: a decoder configured to decode a first display command and output a decoding signal and first synchronizing information indicating the first display command is received; a control circuit configured to generate a first control signal based on second synchronizing information and the decoding signal, the second synchronizing information being output from a second display controller and indicating if a second display command is received; and a video output logic circuit 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 based on the first control signal, wherein the control circuit is configured to generate a second control signal according to a result of comparing a start time-point of a first signal among the plurality of first timing control signals with a start time-point of a second signal among a plurality of second timing control signals generated by the second display controller, and the video output logic circuit is configured to control the start time-point of the first signal in response to the second control signal.
