| 20120067506 | FILM PROCESSING EQUIPMENT AND METHOD USING THE SAME - A film processing equipment and a method for processing a film is provided. A feeding roller feeds the film to a swelling bath and the swelling bath immerses the film. A dyeing bath dyes the film transferred from the swelling bath and a stretching bath stretches the film. The stretching bath comprises three sets of rollers dividing a film transferring path into a first interval length and a second interval length. The first interval length is in an upstream with respect to the film transferring path and smaller than the second interval length. A crosslinking bath performs a crosslinking process on the film transferred from the stretching bath and a washing bath washes the film. A film attaching assembly performs a film attaching process on the film transferred from the washing bath and a winding device winds the film transferred from the film attaching assembly. | 03-22-2012 |
| 20110317262 | Optical Film and Stereoscopic Display Using the Same - An optical film used in a display panel is provided. The display panel has a number of pixels. The optical film includes a condenser lens array layer and a prism array layer. The condenser lens array layer, disposed in front of the pixels, includes a number of condenser lenses and at least has a first portion and a second portion, wherein the first portion and the second portion do not overlap with each other. The prism array layer at least includes a first prism sub-array having a number of first prisms. The light passing through the condenser lenses in the first portion of the condenser lens array layer is deflected to a first direction by the first prisms. The light passing through the condenser lenses in the second portion of the condenser lens array layer travels along a second direction. The first direction is different from the second direction. | 12-29-2011 |
| 20110292330 | Patterned Retarder Film and Method for Manufacturing the Same - A patterned retarder film comprises a first substrate, a pattern configuration, an alignment layer formed on the pattern configuration, and a liquid crystal layer disposed on the alignment layer. The pattern configuration comprises a plurality of first regions and a plurality of second regions, wherein the first regions are grating relief structure and interleaved with the second regions. A liquid crystal layer is coated on the alignment layer to cover the first regions and the second regions of the pattern configuration to a plane with a determined thickness on the surface of the first regions. The first phase retardation of the liquid crystal layer on the first regions and the second phase retardation of the liquid crystal layer on the second regions are different by 180°. The method for manufacturing the same is disclosed. | 12-01-2011 |
| 20110292329 | Patterned Retarder Film and Method for Manufacturing - A patterned retarder film and a method for manufacturing the same are provided. A patterned retarder film with a micro-structure comprises a first substrate, a phase retardation layer on the first substrate comprising a plurality of first retardation regions of liquid crystal materials and a plurality of second retardation regions of curable resin, wherein the structures of the first retardation regions and the second retardation regions are grating-like stripe structures and parallelly interleaved with each other and the first retardation regions provide a first phase retardation and the second retardation regions provide a second phase retardation; and a second substrate laminated on the phase retardation layer; wherein the first phase retardation and the second phase retardation are different by 180°. The method for manufacturing the patterned retarder film is also disclosed | 12-01-2011 |
| 20110292328 | Patterned Retarder Film and Method for Manufacturing the Same - A patterned retarder film with a plurality of first retardation regions and a plurality of second retardation regions and a method for manufacturing the same are provided. The method includes providing a base film; forming an alignment layer on a first surface of the base film; coating a liquid crystal material on the alignment layer as a liquid crystal layer; aligning the liquid crystal layer with the alignment layer; embossing the liquid crystal layer with a predetermined pattern to form a patterned layer with a plurality of first and second retardation regions. The structure of the first and second retardation regions are grating-like stripe structure and parallel to each other and the structure of the second retardation regions are grooving-like stripe structure and interleaved with each other. The patterned liquid crystal layer is cured. The phase retardation of the first and second retardation regions is different by 180°. | 12-01-2011 |
