Gate-in-panel gate driver and organic light emitting display device having the same

Abstract:

An organic light emitting display (OLED) device comprises: a display panel including a substrate, a plurality of data lines on the substrate, a plurality of gate lines on the substrate and oriented transverse to the data lines, and a plurality of pixels connected to the data lines and the gate lines. A data driver supplies data voltages to the data lines, and a gate-in-panel (GIP) gate driver supplies gate pulses to the gate lines. The gate driver drives the display panel in a plurality of blocks of pixel lines within one frame. The data voltages are sequentially supplied to pixel lines of a jth block (j is a natural number) during a data writing period, and a black image is written simultaneously to pixel lines of a qth block (q is a natural number different from j) during a black data insertion period.
