  • Display driver, operating method thereof, host for controlling the display driver, and system having the display driver and the host
    Patent number: 9318072
    Abstract: An operation method of a display driver includes generating a count value by counting a period of a synchronization signal related to a synchronization packet received from a host, receiving a mode change command from the host, the mode change command indicating a change from a video mode transmitting first image data to a display by bypassing a frame memory to a command mode transmitting second image data to the display through the frame memory, and generating an internal synchronization signal having a period substantially equal to the period of the synchronization signal by using the count value based on the mode change command after a last pulse of the synchronization signal is generated. A time interval between the last pulse and a first pulse of the internal synchronization signal is equal to the period of the synchronization signal.
