DISPLAY APPARATUS AND METHOD OF DRIVING THE SAME

摘要

A display apparatus includes a scan line driver and a data line driver. The data line driver supplies data signals to turn on or off pixel circuits connected to selected scan lines. The pixel circuits are turned on or off in sub frames. For each scan line, the sub frames are assigned in the display period based on a reference point. During a preliminary period, the scan line driver selects a scan line and the data line driving circuit supplies a data signal to the pixel circuit based on the reference point. During the display period, the scan line driver selects scan line connected to the pixel circuit in synchronization with an initiation timing of each sub frame of the display period. The data line driver supplies the data signal to the pixel circuit based on the state of the sub frame corresponding to initiation timing.
