/Display Device
Abstract

A display device employs first scan signals having a turn-on level that determines when pixels receive data voltages and second scan signals having a turn-on level that determines times for initializing anode voltages of light emitting elements in the pixels. An active period in a frame period is from a time when the pixels receive an initial first scan signal at the turn-on level to when the pixels receive a last first scan signal of the turn-on level. A blank period in the frame period is from when the pixels receive the last first scan signal at the last turn-on level to when the pixels receive an initial first scan signal of the turn-on level during a next frame period. The blank period is at least as long as a cycle in which each of the pixels receives the second scan signals at the turn-on level.
