Abstract

Image quality and power management associated with a LCD panel are balanced with selective enabling and disabling of response time compensation to selection of liquid crystal material states. A power manager disables overdrive voltages for response time compensation with one or more predetermined conditions, such as reliance on internal power or display of non-moving graphics, and enables overdrive voltages with other predetermined conditions, such as reliance on external power or display of moving graphics. Selective enabling and disabling of response time compensation for setting liquid crystal material states ensures highest quality video graphics with appropriate images while reducing unnecessary power consumption when high quality video graphics provide less benefit, such as with lower quality images.
