Patent ID: 7286106

Claim:
A display panel of an image display device including a plurality of data lines for transmitting data voltages which represent image signals, a plurality of scan lines for transmitting select signals, and a plurality of pixel circuits coupled to the data lines and the scan lines, wherein each said pixel circuit comprises: a driver for outputting a current corresponding to a corresponding said data voltage applied from a corresponding said data line; a display element for displaying an image corresponding to an amount of the current outputted by the driver; a first switch for transmitting the corresponding said data voltage to the driver in response to a corresponding said select signal applied from a corresponding said scan line; a second switch for transmitting a precharge voltage to the driver in response to a first control signal, wherein a value of the precharge voltage during a period in which the first control signal is applied to the second switch is different from the value of the precharge voltage during other periods; and a third switch for interrupting the current from the driver to the display element while the first control signal is being applied, wherein the driver comprises: a driving transistor, coupled between a power source and the display element, for outputting the current to the display element in correspondence to the corresponding said data voltage applied to a gate; a compensation transistor, coupled between the first switch and the second switch, being diode-connected, and having a gate coupled to the gate of the driving transistor; and a capacitor coupled between the gate and a source of the driving transistor.
