  • Patent number: 7821583
    Abstract: A three-dimension display suitable for a viewer wearing a pair of eyeglasses is disclosed. The eyeglasses have two circular polarized eyeglass lenses with different polarizations. The three-dimension display includes a flat display panel, a quarter-wave plate and a patterned half-wave plate. The flat display panel has a plurality of pixels arranged in an array, wherein the flat display panel is suitable to display a linear polarized image. The quarter-wave plate is disposed between the flat display panel and the eyeglasses. The patterned half-wave plate is disposed between the flat display panel and the eyeglasses, wherein the patterned half-wave plate corresponds to a part of the pixels. The present invention also provides a fabrication method of a three-dimension display.

  • Publication number: 20100047468
    Abstract: A method of forming transflective LCD panel includes forming a compensation material having reactive liquid crystal monomers, thermal initiators and a solvent on a first substrate. Then, a first heating process is performed on the compensation material to remove parts of the solvent and then a photo-polymerizing process is performed, and parts of the compensation material disposed in a reflective region are turned into birefringent zones. Moreover, a second heating process is performed, in which the first substrate is kept in a predetermined temperature for a predetermined time, and thereafter nitrogen gas flows in to the chamber to form a non-oxygen condition. Accordingly, parts of the compensation material disposed in a transmission region are turned into isotropic zones. The predetermined temperature of the second heating process is higher than the cleaning point of the reactive liquid crystal monomers.

  • Publication number: 20090168397
    Abstract: An optical film of a display and a method for producing the same are provided. The display includes a light source and an optical film. The light source provides the first light. The optical film includes at least one coating layer. The coating layer has a first surface and a second surface opposite to the first surface. The coating layer is adapted to absorb the first light from the first surface to excite a second light to emit through the second surface. The intensity of the second light is larger than that of the first light.
