Abstract: A pixel for a display panel includes an organic light emitting diode and two driving transistors. The first driving transistor supplies current from a first power source to the organic light emitting diode based on a voltage applied to a first node. The second driving transistor coupled between an electrode of the first driving transistor and the organic light emitting diode. The second driving transistor is turned on or turned off corresponding to a data signal supplied from a data line. A third transistor, coupled between a gate electrode of the second driving transistor and the data line, is turned on when a scan signal is supplied to a scan line. A compensation circuit is coupled to the first node to compensate for a voltage corresponding to a threshold voltage of the first driving transistor.

Abstract: A gate driver includes a plurality of shift registers and a plurality of connection controllers. The shift registers are connected to a plurality of gate lines of a stretchable display panel, respectively. The shift registers are grouped into a plurality of shift register groups. N adjacent shift registers constitute each of the shift register groups, where N is an integer greater than or equal to 2. The connection controllers change a connection structure of the N adjacent shift registers included in the each of the shift register groups according to whether the stretchable display panel is stretched.

Abstract: A data processing apparatus includes a diagonal detector, a first processor, and a second processor. The diagonal detector may determine whether a red-blue data set includes data for controlling a display device to display any diagonal line, the display device including subpixels arranged in first-type lines and second-type lines that are alternately disposed, the red-blue data set including 9 data values that correspond to 9 subpixels among the subpixels, the 9 subpixels forming a 3-by-3 array that includes a center subpixel, the 9 data values including a center data value that corresponds to the center subpixel. The first/second processor may process the center data value using a first/second coefficient to produce a first/second value that corresponds to the center subpixel if the center subpixel is in the first-type/second-type lines.
