Abstract

A method and device for manipulating color in a display is disclosed. In one embodiment, a display comprises interferometric display elements formed to have spectral responses that produce white light. In one embodiment, the produced white light is characterized by a standardized white point.

Claims

1. A method of fabricating a display, comprising:

forming a plurality of display elements configured to output light, each of the plurality of display elements including a reflective surface configured to be positioned at distance from a partially reflective surface, wherein each of the plurality of display elements is formed having the respective distances selected so that white light produced by the plurality display element is characterized by a standardized white point.

2. A display fabricated by the method of claim 1.

3. The method of claim 1, wherein forming the plurality of display elements includes forming at least two display elements wherein the at least two display elements are formed with respective areas from which light is reflected and with respective distances selected so that the at least two display elements produce white light characterized by the standardized white point.

4. The method of claim 1, wherein forming the plurality of display elements includes forming at least one display element configured to output red light, at least one display element configured to output green light, and at least one display element configured to output blue light.

5. The method of claim 1, wherein forming the plurality of display elements includes forming at least one display element configured to output white light.

6. The method of claim 1, further comprising forming at least one filter associated with the at least one display element, the at least one filter configured to selectively transmit certain visible wavelengths and substantially filter other visible wavelengths.

7. The method of claim 1, wherein the distance is selected so that the light reflected by the display has a different white point than light illuminating the display.

8. The method of claim 1, wherein the distance is selected so that the white point is one of D55, D65, or D75.

9. A method of fabricating a display, comprising:

forming a plurality of display elements configured to output light, each of the plurality of display elements including a reflective surface configured to be positioned at distance from partially reflective surface,

wherein each of the display elements are formed with respective areas from which light is reflected and wherein each of the respective areas is selected so that white light produced by the plurality display element is characterized by a standardized white point.

10. The method of claim 9, wherein forming the plurality of display elements includes forming at least one display element configured to output red light, at least one display element configured to output green light, and at least one display element configured to output blue light.

11. The method of claim 9, wherein the respective areas are selected so that the light reflected by the display has a different white point than light illuminating the display.

12. The method of claim 9, wherein the respective areas are selected so that the white point is one of D55, D65, or D75.
