Patent ID: 8842058

Claim:
An organic light emitting display (OLED) comprising: a display panel having a plurality of pixels, wherein each of the pixels is adjacent to an intersection of a scan line and a data line; a scan driver configured to supply scan signals to the scan lines so as to select the pixels; a plurality of demultiplexers configured to supply data signals to the data lines; and a data driver configured to supply the data signals to a plurality of output lines connected to the demultiplexers, wherein each pixel is connected to one of the scan lines and to one of the data lines, and each pixel comprises: an organic light emitting diode; a data line capacitor component directly connected to a ground line and directly connected to the one data line and configured to store voltages corresponding to the data signals supplied to the one data line; and a pixel driving circuit connected to a first power supply line, wherein the pixel driving circuit comprises: a storage capacitor that receives a data voltage from the data line capacitor component and stores the data voltage for a frame, a driving transistor having a gate connected to a first terminal of the storage capacitor, the driving transistor being configured to generate a driving current; a first switching transistor connected to the one data line and to the driving transistor, the first switching transistor being configured to turn on in response to an nth scan signal so as to transmit the data voltage to the driving transistor; and an initialization transistor directly connected between the gate of the driving transistor and an initialization power supply line different from the first power supply line, the initialization transistor being configured to turn on in response to an (n−1)th scan signal to initialize the storage capacitor; wherein the organic light emitting diode is connected between the driving transistor and a second power supply line, and the organic light emitting diode is configured to receive the driving current and to emit light according to the driving current.
