Abstract
A two-dimensional (2D)/three-dimensional (3D) convertible display using a pinhole array, and more particularly, a 2D/3D convertible display, which is easily convertible between the 2D or 3D modes using an electro-optic material of which the refractive index varies according to applied power is provided. A system capable of easily selecting 2D/3D can be used in many fields, which are in need of greatly improved video information, such as medical science, engineering, simulation, and stereoscopic video TV, which will emerge in the near future.
Claims7
A two-dimensional (2D)/three-dimensional (3D) convertible display in a stereoscopic video display comprising:
- an imaging display;
- and
- a pinhole array unit, the pinhole unit being disposed on the front surface of the imaging display and including a liquid crystal layer to which light passes that is emitted from the imaging display, wherein the liquid crystal layer selectively forms a pinhole region and the diameter of the pinhole region is changeable according to externally applied power;
- wherein the pinhole array unit comprises:
- a lower substrate;
- lower electrodes disposed on the lower substrate;
- a liquid crystal layer disposed on the lower electrodes;
- and
- upper electrodes disposed on the liquid crystal layer in a direction perpendicular to the lower electrodes.
