ABSTRACT:
An array of display elements (e.g., pixels) in a display device (e.g., a spatial light modulator) may be digitally driven using pulse width modulated waveforms. Pulse width modulated waveforms may be locally generated to controllably drive each pixel in display systems with digital storage. A pixel drive circuit having a waveform generator may receive first digital data indicative of an optical output from an associated first display element. Moreover, second digital data indicative of a common reference with respect to a second display element may also be received at the first display element for comparison purposes. As a result, in one embodiment, a pulse width modulated waveform that includes only a single transition separating a first pulse interval and a second pulse interval may be generated based on a pixel value and a global count value instead of relying upon adding up multiple non-overlapping waveforms to drive a pixel.
