Abstract
A method and device for manipulating color in a display includes a display in which one or more of the pixels includes one or more display elements, such as interferometric modulators, configured to output colored light and one or more display elements configured to output white light. Other embodiments include methods of making such displays. In addition, embodiments include color displays configured to provide a greater proportion of the intensity of output light in green portions of the visible spectrum in order to increase perceived brightness of the display.
Claims60
A display, comprising:
- a plurality of pixels, each of the pixels comprising:
- at least one red subpixel comprising at least one interferometric modulator configured to output red light;
- at least one green subpixel comprising at least one interferometric modulator configured to output green light;
- at least one blue subpixel comprising at least one interferometric modulator configured to output blue light;
- and
- at least one white subpixel comprising at least one interferometric modulator configured to output colored light.
A display, comprising:
- a plurality of interferometric modulators, said plurality of interferometric modulators comprising:
- at least one interferometric modulator configured to output red light;
- at least one interferometric modulator configured to output green light;
- at least one interferometric modulator configured to output blue light;
- and
- at least one interferometric modulator configured to output white light,
- wherein said at least one interferometric modulator configured to output white light outputs white light having a standardized white point.
A display, comprising:
- a plurality of display elements, each comprising a reflective surface configured to be positioned at a distance from a partially reflective surface, said plurality of display elements comprising at least one of said plurality of display elements configured to output colored light and at least one of said plurality of display elements configured to interferometrically output white light.
A method of fabricating a display, comprising:
- forming a plurality of display elements configured to output light, each of said plurality of display elements comprising a reflective surface configured to be positioned at distance from a partially reflective surface,
- wherein each of said respective distances is selected so that at least one of the plurality of display elements is configured to output colored light and at least one other of said plurality of display elements is configured to interferometrically output white light.
The method of claim 33, wherein said respective distances are selected so that light reflected by said display has a different white point than light illuminating said display.
A display, comprising:
- first means for outputting colored light;
- and
- second means for interferometrically outputting white light, said first and second means comprising microelectromechanical systems.
A display comprising:
- a plurality of pixels each comprising red, green, and blue interferometric modulators that are configured to output red, green, and blue light, respectively,
- wherein each of said pixels are configured to output a greater intensity of green light than red light and configured to output a greater intensity of green light than blue light when each of said interferometric modulators are set to output red, green, and blue light.
A method of fabricating a display, comprising:
- forming a plurality of pixels, forming said plurality of pixels comprising:
- forming interferometric modulators configured to output red light;
- forming interferometric modulators configured to output green light;
- forming interferometric modulators configured to output blue light,
- wherein each of said pixels are configured to output a greater intensity of green light than red light and configured to output a greater intensity of green light than blue light when each of said interferometric modulators are set to output red, green, and blue light.
A display comprising:
- a plurality of pixels each comprising red, green, and blue interferometric modulators that are configured to output red, green, and blue light, respectively,
- wherein each of said pixels are configured to output a greater intensity of green light than red light and configured to output a greater intensity of green light than blue light and
- wherein at least one of said interferometric modulators configured to output red light and said interferometric modulators configured to output blue light are configured to output light having a wavelength selected to compensate for said greater intensity of green light.
