    摘要: A display device includes a light emitting diode, and first and second driving transistors connected between a driving voltage and the light emitting diode to supply driving electric current to the light emitting diode. A control voltage or control voltages differentiated in polarity from each other is/are applied to control terminals of the first and the second driving transistors. The first driving transistor has a control electrode located below a semiconductor layer of the light emitting diode while the second driving transistor has a control electrode located over the semiconductor layer. Two driving transistors are formed at each pixel, and an area occupied thereof within the pixel is reduced. Control voltages differentiated in polarity from each other are applied to the respective driving transistors, substantially preventing deterioration of the driving transistors.

    摘要: A touch sensor is installed inside a liquid crystal display panel to sense a touch operation and includes a light sensing part including a photodiode, a capacitance sensing part including a liquid crystal capacitor, and a sensing signal output part. The light sensing part generates a control signal corresponding to a variation in the amount of external light when the liquid crystal display panel is touched. The capacitance sensing part varies the control signal based on a variation in the capacitance of the liquid crystal capacitor when the liquid crystal display panel is touched. The sensing signal output part generates a sensing signal in response to the control signal and determines an output timing of the sensing signal.
