Abstract
A light-emitting display device and a method of driving the same including scan signals having a turn-on level voltage concurrently supplied to N scan lines of a plurality of scan lines during a first supply period in which the scan signals having a turn-on level voltage are supplied first, for each of the N scan lines corresponding to N subpixel lines included in each of M blocks into which subpixels are grouped, the scan signals having a turn-on level voltage may be supplied to the N scan lines during a second supply period for each of the N scan lines, in which the scan signals having a turn-on level voltage are supplied second, and time intervals of the N scan lines between the first supply period and the second supply period may be the same or have a difference within a preset range, thereby not only securing sensing and compensating times during driving of an image display through block driving, but also preventing luminance non-uniformity during the block driving.
