Abstract

Described are devices and methods for reducing the need for storage on a display panel, for reducing the required bandwidth to a display panel, for increasing the light-on time for a display panel.

Claims (36)

1. A device comprising a spatial light modulator comprising:

a pixel array, and a

plurality of processing elements,

wherein a pixel drive for each respective multi-primary color of each pixel of the pixel array is determined by one or more processing elements of the plurality of processing elements based on one or more multi-primary base values and one or more quantized sharpener values,

wherein the device comprises a partitioner for partitioning the pixel array into groups of pixels, and wherein a respective pixel drive for a respective multi-primary color for each pixel for each group of pixels of the pixel array is determined based on a common multi-primary base value, and

wherein the partitioner comprises a boundary shifter for altering partitioning of the pixel array between frames and/or fields displayed on a display device.

2. The device of claim 1 , wherein there are a plurality of multi-primary colors for each pixel, and wherein a pixel drive for two or more of the multi-primary colors for each pixel is determined by the one or more processing elements based on a common sharpener value.

3. The device of claim 1 , wherein the pixel array is for an RGB display, and a plurality of processing elements, and wherein each of the one or more multi-primary base values is for the color red, blue or green.

4. A device comprising a reconstructor for producing a reconstructed image based on pulse widths of pulses generated by the reconstructor,

wherein the pulse widths of the pulses are generated by the reconstructor based on a base image and a sharpener image,

wherein the sharpener image comprises quantized sharpener values,

wherein there is one quantized sharpener value for each pixel of the reconstructed image, and

wherein a first edge of each pulse is controlled by a base value and a second edge of each pulse is controlled by a decoded sharpener value.

5. The device of claim 4 , wherein the reconstructor comprises a spatial light modulator.

6. The device of claim 4 , wherein the reconstructor comprises hardware and/or software producing a pixel control signal form of a reconstructed image.

7. The device of claim 4 , wherein the reconstructor comprises a plurality of processing elements for computing a plurality of control signals for multiple pixels at or about the same time.

8. The device of claim 4 , wherein the device comprises a spatial light modulator comprising a pixel array of pixels, and wherein respective pixels of the pixel array are driven by reconstructor elements based on the base image and/or sharpener image.

9. The device of claim 4 , wherein the device is a computer.

10. The device of claim 4 , wherein the reconstructed image and the base image are in an RGB format.

11. A method comprising the following steps:

(a) producing a reconstructed image based on pulse widths of pulses, and

(b) displaying the reconstructed image on a visual display device, saving the reconstructed image to a storage medium and/or transmitting the reconstructed image to a computer,

wherein the pulse widths of the pulses are based on a base image and a sharpener image,

wherein the sharpener image comprises quantized sharpener values,

wherein there is one quantized sharpener value for each pixel of the reconstructed image, and

wherein a first edge of each pulse is controlled by a base value and a second edge of each pulse is controlled by a decoded sharpener value.

12. The method of claim 11 , wherein step (b) comprises displaying the reconstructed image on a visual display device.

13. The method of claim 11 , wherein step (b) comprises saving the reconstructed image to a storage medium.

14. The method of claim 11 , wherein step (b) comprises transmitting the reconstructed image to a computer.

15. The method of claim 11 , wherein the reconstructed image and the base image are in an RGB format.

16. A device comprising a reconstructor for producing a reconstructed image based on pulse widths of pulses generated by the reconstructor,

wherein the pulse widths of the pulses are generated by the reconstructor based on a base image and a sharpener image,

wherein at least one bit position of the base image is a color-locking indicator, wherein the sharpener image comprises quantized sharpener values,

wherein there is one quantized sharpener value for each pixel of the reconstructed image, and

wherein a first edge of each pulse is controlled by a base value and a second edge of each pulse is controlled by a decoded sharpener value.

17. The device of claim 16 , wherein the reconstructed image and the base image are in an RGB format.
