Patent ID: 7446740

Claim:
An image display device, comprising: a data line for transmitting a data voltage corresponding to an image signal; a scan line for transmitting a select signal; and a pixel circuit coupled to the data line and the scan line, wherein the pixel circuit comprises: a display element; a first transistor having a first electrode, a second electrode coupled to a power, and a third electrode coupled to the display element; a first switch for diode-connecting the first transistor in response to the select signal; a second switch for coupling a first electrode of a first capacitor to the power in response to the select signal; a second electrode of the first capacitor coupled to the first electrode of the first transistor; a second capacitor having a first electrode coupled to the power; a third switch for transmitting the data voltage to a second electrode of the second capacitor in response to the select signal; and a fourth switch, coupled between the first electrode of the first capacitor and the second electrode of the second capacitor, for intercepting the first electrode of the first capacitor and the second electrode of the second capacitor in response to the select signal.
