Abstract:

A significant part of the energy consumed by a flat panel display is dissipated in the controlling circuitry. The column line flat panel display driver proposed in (Saas et al., 2004) has shown the high potential of stepwise charging to reduce the power dissipation while driving the column lines of the display. The driver has been extended to full dynamic resolution in (Saas et al., 2005), thus allowing market relevant image quality. In this work a method for high efficient recharging of the temporary supply sources in the driver is presented. In the proposed approach the charging current is switched to avoid static bias currents.
