Abstract
The description relates to display devices. One example can receive a first frame rendering that expresses color content with a defined number of bits that convey a set of color states that correspond to a first range of voltages for driving light emitting diodes (LEDs) of a display. The example can obtain information about degradation of the LEDs of the display. The example can also combine the defined number of bits that express the color content with additional degradation compensation overdrive bits relating to compensating for the degradation of the LEDs of the display. The example can map the combined defined number of bits and the additional degradation compensation overdrive bits to a second range of voltages for driving the display where individual values of the second range exceed the first range.
