Abstract
A three-dimensional display apparatus capable of producing an image in three dimensions without the aid of optical illusions or perspective trickery. The display apparatus is comprised of a plurality of pixels which are, in turn, comprised of a plurality of cells. The cells illuminate in one of the three primary colors red, green and blue such that a combination of a red, green and blue cell into a pixel, is capable of producing any color in the visible spectrum. The cells are oriented in the pixel such that light from the pixel is perceivable in six directions, thereby creating a three-dimensional light source. By combining a plurality of these three-dimensional light sources, i.e. a plurality of pixels in a three-dimensional matrix, a three-dimensional image is capable of being displayed.
Claims42
A light emitting element, comprising:
- a plurality of walls configured in a pyramidal shape to enclose a volume filled with a gas;
- an anode;
- a cathode;
- and
- a light emitting material that emits light when energized, wherein when the cathode and anode are electrically charged, a discharge is created between the anode and cathode electrically exciting the gas in the volume to energize the light emitting material,
- wherein each wall of the plurality of walls is transparent to visible light and not transparent to ultraviolet light.
A light emitting element, comprising:
- a plurality of walls configured in a pyramidal shape to enclose a volume filled with a gas, wherein the pyramidal shape is configured such that the height is one half the width of one side of the pyramidal shape;
- an anode;
- a cathode;
- and
- a light emitting material that emits light when energized, wherein when the cathode and anode are electrically charged, the light emitting material is energized.
A cell for use in a three-dimensional display, comprising:
- a plurality of cell walls defining a gas filled volume;
- a positively charged element;
- a negatively charged element;
- and
- a light emitting element, wherein, when the positively charge element and the negatively charged element are charged, a discharge is created between the positively and negatively charged elements, and wherein the discharge energizes the gas causing the light emitting element to emit light, wherein each cell wall of the plurality of cell walls is transparent to visible light and not transparent to ultraviolet light.
A cell for use in a three-dimensional display, comprising:
- a plurality of cell walls defining a gas filled volume, wherein the cell walls are configured in a pyramidal shape having a height that is one half the width of one side of the pyramidal shape;
- a positively charged element;
- a negatively charged element;
- and
- a light emitting element, wherein, when the positively charge element and the negatively charged element are charged, the light emitting element emits light.
A light emitting element, comprising:
- a plurality of walls defining a gas filled volume, the walls being arranged in a pyramidal shape having a height that is one half the width of one side of the pyramidal shape;
- a first electrical element;
- a second electrical element;
- and
- a light emitting element, wherein, when the first and second electrical elements are charged, a discharge is created between the first and second elements, and wherein the discharge energizes the light emitting element to emit light that passes through each of the plurality of walls.
