20100214526 | TOOL FOR USE IN AFFIXING AN OPTICAL COMPONENT TO A LIQUID CRYSTAL DISPLAY (LCD) - A tool for use in affixing an optical component, such as glass, to a liquid crystal display (LCD) using a silicone gel mixture of dimethyl siloxane and a vinyl terminated dimethyl polymer includes, in one embodiment, a unitary metallic platen that is shaped to define a central window. A narrow shelf is defined around the outer periphery of the central window, the shelf serving to support the optical component during the application of the silicone gel thereon. A upwardly extending partition is formed onto the top surface of the platen around the shelf, the partition serving, among other things, to retain the optical component fixed in place on the platen during the assembly process. A plurality of identical, spaced apart, upwardly extending standoffs are formed onto the free end of the partition and are designed to support the LCD a fixed distance away from the optical component. In this manner, it is to be understood that the plurality of standoffs ensure that the layer of silicone gel deposited between the optical component and the LCD is uniform in thickness to optimize performance. | 08-26-2010 |
20120002155 | METHOD AND SYSTEM FOR REPAIRING FLAT PANEL DISPLAY - The present invention provides a method and system for repairing flat panel display, which repairing hot pixels of the flat panel display by femtosecond laser. The flat panel display comprises a LCD module and a color filter disposed on the top of the LCD module, wherein the surface of the color filter corresponding to the LCD module further has a color photoresist layer. The femtosecond laser is projected onto the color photoresist layer corresponding to the hot pixels such that a phenomenon of nonlinear multiple photons absorption can be occurred to change property of the color photoresist layer so as to transform the hot pixels into dead pixels. | 01-05-2012 |
20120002156 | Structure of LCD Panel and Method of Manufacturing the Same - Pixel electrodes in a liquid crystal panel extend to cover the entire pixel regions. The light leakage is generated only on two sides of the pixel region due to the uncontinuous alignment of liquid crystal molecules when the liquid crystal panel is driven by dot inversion. Therefore, in the present invention, light-shielding layer is formed on only the corresponding region of the TFT substrate. The aperture ratio of the liquid crystal panel according to the present invention can increase and the light-shielding layer can be employed to repair the gate lines and data lines. | 01-05-2012 |
