  • Patent number: 11950016
    Abstract: The present invention provides a control method of a receiver. The control method includes the steps of: when the receiver enters a sleep/standby mode, continually detecting an auxiliary signal from an auxiliary channel to generate a detection result; and if the detection result indicates that the auxiliary signal has a preamble or a specific pattern, generating a wake-up control signal to wake up the receiver before successfully receiving the auxiliary signal having a wake-up command.

  • Publication number: 20080096300
    Abstract: A liquid crystal display panel and a manufacturing method thereof are provided. The liquid crystal display panel comprises a color filter substrate and a thin film transistor array substrate arranged in parallel and a liquid crystal layer between the substrates. In addition, several spacers are disposed on a black matrix of the color filter substrate. These spacers lean on the edge of at least one of the gate layer lines and source layer lines on the thin film transistor array substrate. The invention increases the bonding stability between the color filter substrate and the thin film transistor array substrate so that the reliability and display quality of the liquid crystal display panel is improved.

  • Patent number: 7248319
    Abstract: A multi-domain vertical alignment liquid crystal display (MVA LCD) panel has a bottom substrate, a top substrate parallel to the bottom substrate, and a liquid crystal molecule layer filled in between. The panel further has a plurality of pixel regions arranged in arrays on the bottom substrate, a plurality of common lines traversing the pixel regions, a plurality of pixel electrodes positioned in each pixel region above the common lines, a plurality of slits positioned on each pixel electrode, a common electrode layer positioned on the surface of the top substrate, and a plurality of protrusions arranged parallel to and alternatively with the slits and positioned on the surface of the common electrode layer. The protrusions and the common lines are partially overlapped.
