Abstract

A display presents information with pixels driven at overdrive voltages set based upon a user configuration and sensed environmental conditions. Varied overdrive voltages provide adaptable display responses with proportional power consumption so that power consumption is reduced where visual images of a display content have reduced need for rapid display response. For example, reduced bandwidth availability that impacts display resolution allows reduced overdrive voltages that scale to visual content resolution.
