Abstract
A viewing angle expansion plate, which is a multi-pinhole mask, includes a plurality of cell areas; and a plurality of pinholes formed in the plurality of cell areas, wherein each cell area from among the plurality of cell areas corresponds to a respective pixel from among a plurality of pixels in a flat panel display. The flat panel display includes a light source configured to emit parallel light; a flat panel, on which the parallel light is incident, configured to provide a three-dimensional image; and the viewing angle expansion plate.
Claims19
A viewing angle expansion plate comprising:
- a plurality of cell areas;
- and
- a plurality of pinholes formed in the plurality of cell areas,
- wherein each cell area from among the plurality of cell areas corresponds to a respective pixel from among a plurality of pixels in a flat panel display, and
- wherein the plurality of cell areas comprises a first cell area in which a first number of a first plurality of pinholes are formed and a second cell area in which a second number of a second plurality of pinholes are formed, the second number being different from the first number, and
- wherein a number of pinholes formed in each cell area of the plurality of cell areas is different from the number of pinholes formed in each other cell area of the plurality of cell areas.
A method of operating a flat panel display, the flat panel display including:
- a light source configured to emit parallel light;
- a flat panel on which the parallel light is incident, the flat panel being configured to provide a three-dimensional image;
- and
- a viewing angle expansion plate configured to expand the viewing angle of the three-dimensional image, the viewing angle expansion plate comprising:
- a plurality of cell areas;
- and
- a plurality of pinholes formed in the plurality of cell areas,
- wherein each cell area from among the plurality of cell areas corresponds to a respective pixel from among a plurality of pixels in a flat panel display, and
- wherein the plurality of cell areas comprises a first cell area in which a first number of pinholes are formed and a second cell area in which a second number of pinholes are formed, the second number being different from the first number,
- the method comprising moving the viewing angle expansion plate during operation of the flat panel display.
