Patent ID: 8018539

Claim:
A pixel circuit structure applied in a liquid crystal display (LCD) panel that has a common voltage and comprises at least one data line, the pixel circuit structure comprising: a first circuit comprising: a first capacitor whose one end receives the common voltage; and a first switch; and a second circuit comprising: a second switch; a third switch, wherein the first switch, the second switch and the third switch are coupled serially between the data line and a voltage source, and the other end of the first capacitor is coupled between the first switch and the second switch; and a second capacitor whose one end receives the common voltage and the other end is coupled between the second switch and the third switch; wherein the two ends of the first capacitor has a first potential difference and the two ends of the second capacitor has a second potential difference which is different from the first potential difference; wherein the LCD panel further comprises at least one first display region and at least one second display region, and the first circuit is applied to the first display region and the second circuit is applied to the second display region.
