  • Patent number: 8013965
    Abstract: A liquid crystal display device is disclosed, which comprises an upper substrate, a lower substrate, and a liquid crystal layer. The lower substrate has several pixel electrodes, metal lines, and switch elements thereon. Each switch element comprises a source electrode, a drain electrode, a gate electrode, and an opening between the source electrode and the drain electrode. A passivation layer covering the surface of the source electrode and the drain electrode forms two inclined planes separately on two sides. The two inclined planes face each other and are locating on a kink or step of the source electrode and drain electrode. The inclined planes also contact each other at the upper side of the opening. The inclinations of the inclined planes to the lower substrate are in a range from 5 to 50 degrees.

  • Patent number: 7826010
    Abstract: A color filter substrate including a substrate, a number of color filter patterns, a black matrix, a number of spacers, a number of protrusions, and a common electrode is provided. The substrate has a number of sub-pixel regions. The color filter patterns are disposed on the substrate, and each color filter is disposed within one of the sub-pixel regions. The common electrode covers the color filter patterns and the substrate. The black matrix is disposed on the common electrode and between the sub-pixel regions. The spacers are disposed on the black matrix and connected to the black matrix. The protrusions are disposed on the common electrode above the color filter patterns. The black matrix, the spacers, and the protrusions are made of the same material. As mentioned above, a color filter substrate manufactured with low cost is provided.

  • Patent number: 7378200
    Abstract: A method of fabricating a color filter substrate is provided. First, several color filter patterns are formed on a substrate. Then, an opaque layer is formed over the substrate and the color filter patterns. After that, the opaque layer is patterned to form a black matrix between the color filter patterns and several protrusions on the color filter patterns simultaneously. Finally, several spacers are formed on a part of the black matrix.

  • Publication number: 20060085583
    Abstract: The present invention provides a multi-functional integrated circuit card module with a mixed interface, which comprises a controller, multiple first pins and second pins coupled to the controller, and a non-volatile memory whose read/write function is controlled by the controller. The controller works at a first mode after detecting the first pins complying with first interface characteristics while the second pins not complying with second interface characteristics; and the controller works at the first mode plus a second mode after detecting the first pins complying with the first interface characteristics and the second complying with the second interface characteristics.
