Abstract: Provided is a display device including a display panel, a data driver, a gate driver, and a timing controller. The display panel includes first and second pixel line groups each including k (k is a natural greater than 1) pixel lines, and each of the pixel lines includes a plurality of pixels connected to the same gate line. The data driver supplies an image data voltage to the pixels on the basis of input image data. The gate driver supplies a gate pulse to the gate line. The timing controller controls a driving timing of the data driver and the gate driver, sequentially writes the image data voltage into pixel lines belonging to the first pixel line group during an image data write period and simultaneously writes a black data voltage into pixel lines belonging to the second pixel line group during a black data insertion (BDI) period. The timing controller changes an interval between timings for writing the black data voltage from a start timing of a frame on a frame-by-frame basis.

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.

Abstract: A gate shift register and an organic light emitting diode display including the same are disclosed. The gate shift register includes a first stage and a second stage that output image display gate pulses during an image data writing period and selectively output a sensing gate pulse in a vertical blanking interval in which image display data is not written. The first stage includes a node Q1, a node Qbo, a node M, a first sensing control block activating the node Q1, and a second sensing control block deactivating the node Qbo. The second stage includes a node Q2, a node Qbe, a third sensing control block activating the node Q2, and a fourth sensing control block deactivating the node Qbe. The first stage and the second stage share a partial circuit necessary for driving with each other.
