1. A system to compensate for luminance degradation of a display, the system comprising:
- a luminance control system coupled to the display and configured to provide power to the display thereby controlling the display luminance, the luminance control system including an input to receive a consumption rate (CR) limit;
a temperature sensor proximate the display and in electrical communication with a controller,wherein the luminance control system is configured to vary the display luminance, based on a temperature measured by the temperature sensor and the CR limit.

Abstract
A system to compensate for luminance degradation of an emissive display is provided. The system employs a combination of a consumption rate limit and temperature to regulate and control display luminance for emissive displays (such as organic light emitting diodes). A consumption rate limit is employed to determine a display luminance ceiling at which to drive the display. By employing the aspects disclosed herein, the display systems may achieve a longer lifetime.
