  • Patent number: 6888598
    Abstract: A liquid crystal display device includes an upper substrate and a lower substrate facing and spaced apart from each other; an upper orientation film on an inner surface of the upper substrate; a lower orientation film on an inner surface of the lower substrate; a liquid crystal layer interposed between the upper and lower orientation films; an upper polarizing plate on an outer surface of the upper substrate; a lower polarizing plate on an outer surface of the lower substrate; and at least one compensation film disposed between the upper substrate and the upper polarizing plate or between the lower substrate and the lower polarizing plate. In the typical IPS-LCD device with a wide viewing angle, since the metallic black matrix of the upper substrate affects the voltage between the common and pixel electrodes, the black matrix is made of resin and cannot be formed with a bent portion because of the limits of the processing technology.

  • Patent number: 6879365
    Abstract: An improved flat panel display provides reduced reflection of incident light on the display to improve display visibility. The display includes a transparent top cover panel such as glass which is bonded or laminated to the display polarizer. The outer viewing surface of the top cover panel carries a plurality of integral surface features defined in the surface, which may comprise etched bumps or micro-machined tetrahedron-shaped protuberances that may be truncated, smoothed, and/or variously oriented and sized to further reduce incident light reflectivity. A multi-layer HEA coating on the featured surface defines a graduated transition layer with an index of refraction that gradually, and preferably smoothly, varies from layer to layer of the HEA coating from the index of refraction of the top cover panel to the index of refraction of the ambient air or other material which the outermost viewable surface of the display presents an image to an observer or viewer.

  • Patent number: 6856361
    Abstract: A liquid crystal display according to the present invention uses an organic layer treated with H2 plasma before fabricating an inorganic layer on the top of the organic layer. When forming thin film transistors (TFT) used in the LCD, an Indium Tin Oxide layer is fabricated above the TFTs and acts as a pixel electrode. When the organic layer, such as a passivation layer, is treated with the H2 plasma, an intermediate layer having an O—H bonding structure is formed to enhance bonding or attachment of an inorganic layer, such as an ITO layer, to the organic layer.

  • Patent number: 6847424
    Abstract: A liquid-crystal display includes a reflective liquid-crystal panel, a light guiding plate disposed on the reflective liquid-crystal panel, a polarizer arranged between a liquid-crystal layer of the reflective liquid-crystal panel and the light guiding plate, and a light source disposed on a side surface of the light guiding plate. Light emitted from the light source propagates through the light guiding plate and has a primary direction. A smaller one of two angles between a projection of the primary direction onto the reflective liquid-crystal panel and an absorption axis of the light guiding plate is at least 50°. This resultantly improves performance of the liquid-crystal display.
