Optical interference pixel display with charge control
First Claim
1. An electronic device for at least partially displaying a pixel of a displayable image comprising:
- a first reflector and a second reflector defining an optical cavity therebetween and selective of a visible wavelength at an intensity by optical interference; and
, a charge-controlling mechanism to allow optical properties of the optical cavity to be varied by controlling a predetermined amount of charge stored on the first and the second reflectors, such that at least one of the visible wavelength and the intensity are variably selectable in correspondence with the pixel of the displayable image.

Abstract
An electronic device of an embodiment of the invention is for at least partially displaying a pixel of a displayable image. The electronic device includes a first reflector and a second reflector that define an optical cavity therebetween, and which is selective of a visible wavelength at an intensity by optical interference. The electronic device also includes a charge-controlling mechanism to allow optical properties of the optical cavity to be varied by controlling a predetermined amount of charge stored on the first and the second reflectors. The visible wavelength and/or the intensity are thus variably selectable in correspondence with the pixel of the displayable image.
