Abstract
A system and method are provided for driving a digital display adapted to depict a first number of bits per color field during each frame. In use, a second number of bits is displayed which is greater than the first number of bits. This is accomplished by alternating the display of the bits between frames. To this end, additional bits of color are displayed without increasing the number of bits per color field during each frame.
Claims10
An image generation system, comprising:
- (a) a plurality of display elements, each display element including a pixel;
- (b) a plurality of circuits each electrically coupled to a display element;
- (c) a plurality of memory cells associated with each of the circuits and a selector for outputting to the display element from one memory cell at a time;
- (d) an illumination source for illuminating one or more pixels in a particular color;
- (e) a light emitting mechanism and a light modulating mechanism coupled with each of the one or more pixels;
- and
- (f) logic for generating a plurality of sequential frames for displaying N+M bits of color, wherein each of the plurality of sequential frames is generated with only N bits of color such that there are M bits of color difference spatially distributed over M pixel groups of the plurality of sequential frames without increasing the number of bits per color field during each frame.

A method for driving a digital display, comprising the steps of:
- (a) providing a digital display adapted to display a first number of bits per color field during each frame;
- and
- (b) displaying a second number of bits greater than the first number of bits by spatially distributing in each frame a difference of the second number of bits so that an average of the frames represents a combination of the first and second number of bits;
- (c) wherein the first and second number of bits of color are displayed without increasing the number of bits per color field during each frame.
