Abstract
The present invention provides techniques for emissive pixels of flat panel displays. Specifically, pixel feedback and a combination of voltage modulation and pulse width modulation are used to improve the quality and consistency of aging pixels. Based on feedback, an image frame is divided into sub-frames of various time periods. Also based on feedback, a voltage, or voltages of different voltage levels, is (are) applied to the selected sub-frames to generate an image frame of a particular gray level. The human eye integrates the effects of the voltage and pulse width modulation techniques that are applied to the various sub-frames of the image frame, over the duration of the image frame.
