Claim 7:
8. A light emitting display device comprising:
a display panel including a plurality of pixel groups in which a plurality of pixels are grouped in units of a plurality of rows, the display panel being configured to drive pixels in an odd-numbered row or to drive pixels in an even-numbered row; and
a gate driver including a scan signal unit for applying configured to apply a scan signal to the plurality of pixels and an emission signal unit for applying configured to apply an emission signal to the plurality of pixels,
wherein the emission signal unit is configured to apply the same emission signal to pixels included in the same pixel group among the plurality of pixels,
wherein, in a first frame and a second frame, a first time at which a first emission signal that is applied to a first pixel group among the plurality of pixel groups is inverted from a gate-off voltage to a gate-on voltage, and a second time at which a second emission signal that is applied to a second pixel group among the plurality of pixel groups is inverted from the gate-on voltage to the gate-off voltage differ from each other, so that the display panel is configured to alternately display the first frame in which dark lines are visible and the second frame in which bright lines are visible at a boundary between the plurality of pixel groups,
wherein, in the first frame, the first time of the first emission signal and the second time of the second emission signal are different from each other,
wherein, in the first frame, the first time of the first emission signal is slower than the second time of the second emission signal,
wherein, in the second frame, the first time of the first emission signal is slower than the second time of the second emission signal,
wherein the first time of the first emission signal in the first frame and the first time of the first emission signal in the second frame are different from each other, and
wherein the second time of the second emission signal in the first frame and the second time of the second emission signal in the second frame are different from each other.
