Method and apparatus for providing brightness control in an interferometric modulator (IMOD) display
First Claim
1. An interferometric modulator display pixel comprising:
- a microelectromechanical systems (MEMS) interferometric modulator having an associated first color spectrum indicating a reflectance of light at a first pre-determined peak wavelength, wherein the microelectromechanical systems (MEMS) interferometric modulator is operable to shift the first color spectrum relative to a second color spectrum to control a visual brightness of the interferometric modulator display pixel independent of a color of the interferometric modulator display pixel, the second color spectrum indicating absorption of light except at a second pre-determined peak wavelength that is different from the first pre-determined wavelength.

Abstract
Methods and systems for providing brightness control in an interferometric modulator (IMOD) display are provided. In one embodiment, an interferometric modulator display pixel is provided that includes a microelectromechanical systems (MEMS) interferometric modulator having an associated first color spectrum, and a color absorber located substantially in front of the interferometric modulator display pixel, in which the color absorber has an associated second color spectrum. The microelectromechanical systems (MEMS) interferometric modulator is operable to shift the first color spectrum relative to the second color spectrum to control a visual brightness of the interferometric modulator display pixel independent of a color of the interferometric modulator display pixel.
