Claims
- 1. 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 that displays additional bits of color without increasing the number of bits per color field during each frame.
- 2. An image generation system as recited in claim 1, wherein N+M bits of color are displayed using N digital bits per color field.
- 3. An image generation system as recited in claim 2, wherein additional color are applied in a spatially distributed manner to reduce the amount of brightness modulation that is observed.
- 4. An image generation system as recited in claim 2, wherein an additional color bit is calculated based on the value of the preceding bit being added to every other frame.
- 5. An image generation system as recited in claim 2, wherein a given frame is not displayed which results in a reduction of a perceived intensity modulation and flicker reduction.
- 6. The image generation system as recited in claim 1, wherein the digital display is an active matrix panel display.
- 7. 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 alternating the display of the bits between frames; (c) wherein additional bits of color are displayed without increasing the number of bits per color field during each frame.
- 8. A method as recited in claim 7, wherein N+M bits of color are displayed using N digital bits per color field.
- 9. A method as recited in claim 8, wherein additional color are applied in a spatially distributed manner to reduce the amount of brightness modulation that is observed.
- 10. A method as recited in claim 8, wherein an additional color bit is calculated based on the value of the preceding bit being added to every other frame.
- 11. A method as recited in claim 8, wherein a given frame is not displayed which results in a reduction of a perceived intensity modulation and flicker reduction.
- 12. The method as recited in claim 7, wherein the digital display is an active matrix panel display.
