Abstract:
1. A spatial light modulator comprising: a multi-pixel display array on a first die, a multi-pixel memory array on a second die separate from the first die, the multi-pixel memory array having pixel storage cells, and wherein at least some pixels of the multi-pixel memory array are disposed outside the multi-pixel display array such that the multi-pixel memory array is physically decoupled from the multi-pixel display array; at least one local pulse width modulation drive circuit coupled to at least one of the pixel storage cells; a global counter coupled to the local pulse width modulation drive circuit to provide a global count value thereto, wherein: the display pixels of the multi-pixel display array comprise first display pixels of a first color, and second display pixels of a second color; the global counter includes, a first global counter coupled to the local pulse width modulation drive circuits of the first display pixels, and a second global counter coupled to the local pulse width modulation drive circuits of the second display pixels.
