Abstract:
1. A picture image display device comprising pixels which are formed in a matrix shape defined by a plurality of gate lines to which scanning signals are fed and a plurality of data lines crossing thereto to which picture image signals are fed, and each pixel including an organic light emitting diode and a thin film transistor, wherein the pixels are initially driven in a light emitting portion of a frame period, and then introducing a light quenching period within each frame period, in which the organic light emitting diode is caused to be quenched for a subsequent remaining portion of the frame period following the light emitting portion, by feeding scanning signals to the plurality of gate line as well as picture image signals to the plurality of data lines after feeding scanning signals to the plurality of gate lines for displaying one picture image.
