  • Device and method for driving display in response to image data
    Patent number: 11120732
    Abstract: A display driver includes: a receiver configured to receive image data of each line of a display panel from an external device; a line latch circuit having a line latch configured to latch the image data of each line received by the receiver in response to a strobe signal; a driving circuit section which drives the display panel in response to the image data latched by the line latch; and a timing controller configured to generate the strobe signal. The receiver is configured to detect occurrence of transmission error in data transmission about each line. The timing controller is configured to generate the strobe signal in response to a detection result of the occurrence of transmission error.
