ABSTRACT:
In a display refresh period, an array of display elements (e.g., pixels) forming a display device (e.g., a spatial light modulator) may be driven using selectively updated pulse width modulated waveforms. Decoupling of digital storage, storing display data that generates updated pulse width modulated waveforms, from the array of pixels may provide decoupling of pixel data and pulse width modulated waveform updates. In one embodiment, an update value of pixel data is provided to a display element. Using once the update value, a modulated signal may be generated for a display refresh period to drive the display element, significantly reducing updates required for the pixel data at the display element.
