Abstract
The present disclosure is directed to systems and methods of reducing display image power consumption while maintaining image quality on display devices having a plurality of display power modes. Each display power mode has associated therewith a defined baseline value (K1,BASELINE) first relationship. A display image includes a baseline percentage under-boosted pixels (Xi,BASELINE). Using the first relationship value (K1,BASELINE) and the pixel percentage (Xi,BASELINE), a baseline second relationship value is determined (K0,BASELINE). The value associated with the second relationship is adjusted to a first plurality of values. At each value, the value associated with the pixel percentage is adjusted to each of a second plurality of values. At each combination of second relationship value and pixel percentage, a respective first relationship value is determined. A first relationship value, second relationship value are selected to provide a reduced power consumption while maintaining image quality.
