Abstract

A new overlap-scan circuit that enables a high speed scan or low data voltage scan based on overlapping the scan pulses during a scan-period is proposed for a 42-in. plasma TV. For the overlap between the scan pulses, the proposed overlap-scan circuit consists of three odd and three even drivers that alternately provide the scan pulses to the odd and even scan lines among the 480 scan lines, respectively. Consequently, the proposed overlap-scan circuit can perform either a high-speed scan by reducing the total scan time or a low voltage scan by lowering the address voltage.
