  • Publication number: 20120306828
    Abstract: The invention provides a driving circuit applied in a LCD apparatus and operating method thereof. The driving circuit includes at least one first channel, at least one second channel, a timing controller, and a panel driver. The timing controller includes a digital signal switching unit. The digital signal switching unit selectively performs a polarity exchange to a first digital data signal and a second digital data signal according to a control signal. The panel driver includes an analog signal switching unit. The analog signal switching unit performs a switching corresponding to the polarity exchange according to the control signal to make the driving circuit selectively operated under a first operation mode or a second operation mode.

  • Publication number: 20120075263
    Abstract: A driving circuit and an operating method thereof are disclosed. The driving circuit includes at least one first channel, at least one second channel, a selecting module, and at least one switching module. The selecting module is coupled to input ends of the first channel and the second channel. The at least one switching module is coupled to output ends of the at least one first channel and the at least one second channel. The selecting module and the switching module will perform corresponding switching actions to make the driving circuit selectively under a first operating mode or a second operating mode.

  • Patent number: 7760277
    Abstract: An exemplary active matrix liquid crystal display (AMLCD) panel (20) includes a first substrate (400), a second substrate (600), and a liquid crystal layer (500) sandwiched between the two substrates. The second substrate includes gate lines that are parallel to each other, common lines that are alternate with and parallel to the gate lines, and data lines that are parallel to each other and crossing to the gate lines. The data lines cross the gate lines to define pixel regions. Each of the pixel regions includes a pixel electrode that is between the data lines, a first shielding metal line positioned at a side of the pixel electrode, a second shielding metal line positioned at another side of the pixel electrode. The second shielding metal line is connected to the common line. The first shielding metal line is an electrically floating body.
