Abstract
A reflective member is formed and spaced from a provided partial reflective layer. The reflective member is movable relative to the partial reflective layer. The reflective member is electrically coupled to a surface configured to be impinged by an electron beam
Claims36
An apparatus comprising:
- a partial reflective layer;
- a first reflective member movably supported relative to and spaced from the layer;
- and
- a first electrically conductive surface electrically coupled to at least one of the partial reflective layer and the first reflective member and configured to be impinged upon by an electron beam.

An apparatus comprising:
- a first reflector and a second reflector forming an optical cavity therebetween;
- and
- an electron beam emitting device configured to emit an electron beam, wherein the second reflector moves relative to the first reflector in response to the emitted electron beam.
An electronic device comprising:
- a plurality of pixels, each pixel including a first reflective layer and a second reflective layer forming an optical cavity therebetween;
- at least one electron beam emitting device;
- and
- a controller configured to generate control signals, when the electron beam emitting device selectively directs an electron beam to selectively modify one of the plurality of pixels in response to the control signals.

An apparatus comprising:
- a first reflector and a second reflector forming an optical cavity therebetween;
- and
- means for moving the second reflector relative to the first reflector using an electron beam.
A method comprising:
- creating a first charge on a partial reflective layer;
- and
- creating a second charge on a first reflective member opposite the partially reflective layer with an electron beam to electrostatically move the reflective member relative to the partially reflective layer.
A method comprising:
- creating a first charge on a first reflective member between and opposite to a partial reflective layer and a first electrically conductive layer;
- and
- creating a second charge on the first electrically conductive layer with an electron beam to electrostatically move the first reflective member relative to the partial reflective layer.
A method comprising:
- providing a partial reflective layer;
- and
- forming a reflective member spaced from and movable relative to the partial reflective layer, wherein the reflective member is electrically coupled to a surface configured to be impinged by an electron beam.
A method comprising:
- providing a partially reflective layer;
- providing a reflective member spaced from and movable relative to the partial reflective layer;
- and
- forming an electrically conductive layer opposite the reflective member and electrically coupled to a surface configured to be impinged by an electron beam.
1 more element
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 an electromagnetic wavelength at an intensity by optical interference;
- at least one cathode ray charge controlling mechanism configured to allow optical properties of the optical cavity to be varied by controlling a predetermined amount of charge stored on the first and second reflectors such that at least one of electromagnetic wavelength or intensity are variably selectable in correspondence with the pixel and displayable image.
