A new high-voltage (HV) power IC technology using high-performance p-LDMOS transistors and an excellent dielectric isolation technology has been proposed to apply the scan driver of color plasma display panel (C-PDP) system. This novel technique reduces over 40 process steps and results in smaller chip size area of the developed scan driver than that of conventional driver using conventional power IC technology. The chip size and the rise time of the PDP scan driver IC developed by this technology could be reduced by 35% and 60%, respectively, compared with the conventional design.
