Abstract: There are provided a pixel and an organic light emitting display device using the same capable of improving image quality. A pixel includes an organic light emitting diode, a first transistor, a second transistor and a second capacitor. The first transistor controls the amount of current supplied from a first power to the organic light emitting diode coupled to a second electrode of the first transistor, corresponding to a voltage applied to a second node. The second transistor is coupled between the second electrode of the first transistor and the second node so as to be turned on when a scan signal is supplied to a scan line. The second capacitor is coupled between the second electrode of the first transistor and a control line.

Abstract: An organic light emitting diode (OLED) display is disclosed. In one aspect the display includes a display panel having first through fourth pixels and a scan driving unit that outputs a scan signal to the display panel. The display also includes a data driving unit that alternately outputs a first data signal for the first pixels and a second data signal for the second pixels to the display panel, alternately outputs a third data signal for the third pixels and a fourth data signal for the fourth pixels to the display panel, and begins outputting the first and third data signals before one horizontal period begins The display further includes a demultiplexing unit that alternately applies the first and second data signals to the first and second pixels and the third and fourth data signals to the third and fourth pixels.

Abstract: A touch screen display is disclosed. In one aspect, the touch screen display includes a plurality of first touch electrodes each including first and second ends opposing each other and a plurality of second touch electrodes crossing the first touch electrodes. The touch screen display also includes a first voltage line providing a voltage, a first signal line providing a touch driving signal, and a plurality of first switching units respectively connected to the first touch electrodes. Each of the first switching units is electrically connected to the first voltage line, the first signal line, and the first end of a corresponding first touch electrode. Each of the first switching units alternately provides one of the voltage and the touch driving signal to the corresponding first touch electrode.
