  • Publication number: 20070139587
    Abstract: A transflective liquid crystal display (LCD) panel, a color filter and a fabricating method thereof are provided. The color filter includes a substrate, a light-shielding pattern, a plurality of thickness compensating patterns, and a plurality of color filter patterns. The light-shielding pattern is disposed on the substrate and defines a plurality of sub-pixel regions on the substrate. Wherein, each sub-pixel has a reflecting area and a transparent area. The thickness compensating patterns are disposed in the transparent area. Each of the color filter patterns is disposed in one of the sub-pixel regions and covers the thickness compensating pattern. Therefore, each color filter pattern has two different thicknesses in the reflecting area and the transparent area respectively. The color filter can improve the brightness uniformity and chroma uniformity of the images displayed in various sub-pixel regions of the transflective LCD panel.

  • Patent number: 6967875
    Abstract: The memory system includes a plurality of memory cells that are arranged for forming a column, and the plurality of memory cells are coupled with a first bitline and a second bitline individually. Additionally, the memory system further includes a bitline conditioning circuit to perform the pre-charge procedure thereof; and that includes a plurality of wordlines. Furthermore, the memory system further includes a compensating-circuit to keep the voltage that is requirement for the access procedure, wherein the bitline conditioning circuit and the compensating-circuit couple to receive a pair of complemental signals so as to control the interaction between the pre-charge procedure and the compensation procedure from each other.

  • Patent number: 6755672
    Abstract: A protection cover integrally formed of plastic by molding ejection is provided. An elastic locking structure is disposed at two sides of the protection cover. An abutting portions having a ‘<’-shaped part and a ‘>’-shaped part is formed on the locking structure to abut against the outer edge wall of the connector so that the protection cover and the connector can be firmly connected together. Reinforcement portions are formed at the inner top face and the link positions at two inner sides of the protection cover.

  • Publication number: 20040102068
    Abstract: An improved connector protection cover integrally formed of plastic by molding ejection is provided. An elastic locking structure is disposed at two sides of the protection cover. An abutting portions having a ‘<’-shaped part and a ‘>’-shaped part is formed on the locking structure to abut against the outer edge wall of the connector so that the protection cover and the connector can be firmly connected together. It is not necessary to use a professional tool like a screwdriver to separate the protection cover from the connector. Scrapes on the surface of the connector can also be avoided. Moreover, reinforcement portions are formed at the inner top face and the link positions at two inner sides of the protection cover to prevent the protection cover from crushing terminals in the connector due to stacking of the connectors during transportation.

  • Publication number: 20030142598
    Abstract: An optical pickup tilt control module and a method for controlling a tilt value of an optical pickup to reduce the jitter value of a generated reproducing signal. The optical pickup tilt control module includes a reproducing signal generator, a jitter detector, a tilt controller and a tilt actuator. The reproducing signal generator receives a RF signal generated from the optical pickup and generates an EFM signal. The jitter detector receives the EFM signal and detects a jitter value of the EFM signal. The tilt controller generates optimum tilt control values during a correction stage and outputs a tilt control value according to a track position of reproduction data during an adjusting stage. The tilt actuator controls the tilt of the optical pickup according to the tilt control value.
