The display is often responsible for a large proportion of the overall power consumed by a device. The total power consumption of a display depends on a number of factors such as the number of pixels that need to be switched on, the color and brightness of the pixels, and the rate at which the on-screen content is updated. Displays that draw high amounts of power can deplete the available power resources of a device relatively quickly, thus shortening the amount of time a user can operate the device without needing to charge or replace the device battery. This disclosure describes techniques to specify and enforce a system of rules that dictate the operation of display pixels while rendering the content to be displayed. The rules describe upper or lower bounds for various pixel-related parameters such as switched on state, color, brightness, refresh rate, etc.
