Abstract
Timing information may be embedded along with other display control information in a signal using a pulse width modulation (PWM) mechanism to controllably drive a display (e.g., a plurality of display elements forming an array of display elements). In one embodiment, a non-uniform pulse interval clock may be generated from a uniform pulse interval clock in response to the timing information having pulse interval values. Using the non-uniform pulse interval clock, the width, and optionally the amplitude, of a drive signal may be modulated in order to controllably drive one or more display elements of an array of display elements. For example, while using video data with the non-uniform pulse interval clock to adjust the duration of the drive signal directed to each display element of the array of display elements, calibration data may be simultaneously used to adjust the magnitude of the drive signal. Thus, a gamma correction may be provided jointly with a compensation for initial non-uniformity, degradation over time, and/or non-uniform degradation to the one or more display elements of the array of display elements.
