Abstract
A display driver and display driving method process display data received from a central processing unit (CPU) and output display data voltages. The display driver includes a synchronization controller that sends a reference synchronization signal to the CPU, and controls the CPU to synchronize a write clock with the reference synchronization signal and to send the write clock. A write clock detector detects whether the write clock is received from the CPU and outputs a selection signal in response. A frame memory receives and stores display data of a current frame synchronized with the write clock. A gray-level compensator generates gray-level compensated display data based on the display data of a current frame and display data of a previous frame previously stored in the frame memory. A selector outputs one of the gray-level compensated display data or the display data previously stored in the frame memory as scan data in response to the selection signal.
