Patent ID: 8120572

Claim:
A pixel unit for a liquid crystal display (LCD) panel that has a display region and a non-display region, said pixel unit comprising: first and second pixels disposed in the display region; an active element disposed in the non-display region and coupled to the second pixel; a pair of scan lines, including a first scan line coupled to the first pixel and a second scan line coupled to the active element; a data line; and controlling circuitry configured for placing (i) a first scan signal on the first scan line to drive the first pixel to a first pixel voltage from the data line during a first scan period, (ii) a third scan signal on the first scan line to drive the first pixel to a second pixel voltage from the data line during a second scan period, and (iii) a second scan signal on the second scan line to, collectively with the first scan signal on the first scan line, drive the second pixel to the first pixel voltage from the data line via the active element during the first scan period, wherein during the first scan period, the second scan signal is transmitted via the second scan line to enable the active element.
