Abstract: A display driver integrated circuit (IC) includes a first driver block, a second driver block, and a transmission control circuit. The transmission control circuit is configured to deserialize pixel data groups of a serial data packet and to alternate sending the deserialized pixel data groups to the first driver block and the second driver block. Each of the pixel data groups includes pixel data for at least one pixel.
