  • Publication number: 20100259701
    Abstract: A liquid crystal display (LCD) is provided. The LCD includes a display panel and a voltage supply device (VSD). The display panel includes a plurality of scan lines, a plurality of data lines disposed substantially perpendicularly with the scan lines, and a plurality of pixels. The pixels are respectively electrically connected with the corresponding data line and the corresponding scan line, and are arranged in an array. Each of the pixels includes a common line and a compensation line, wherein the common line is located in the transparent area to receive a common voltage, and the compensation line is located in the reflection area to receive a stable voltage. The VSD is coupled to the compensation line of each of the pixels for continuously and correspondingly providing the stable voltage to the compensation line of each of the pixels.

  • Publication number: 20100238143
    Abstract: A high-reliability gate driving circuit includes a plurality of odd shift register stages and a plurality of even shift register stages. Each odd shift register stage generates a corresponding gate signal furnished to a corresponding odd gate line according to a first clock and a second clock having a phase opposite to the first clock, and further functions to pull down a gate signal of at least one even gate line or at least one odd gate line different from the corresponding odd gate line. Each even shift register stage generates a corresponding gate signal furnished to a corresponding even gate line according to a third clock and a fourth clock having a phase opposite to the third clock, and further functions to pull down a gate signal of at least one odd gate line or at least one even gate line different from the corresponding even gate line.

  • Publication number: 20100059758
    Abstract: A tri-gate pixel structure includes three sub-pixel regions, three gate lines, a data line, three thin film transistors (TFTs), three pixel electrodes, and a common line. The gate lines are disposed along a first direction, and the data line is disposed along a second direction. The TFTs are disposed in the sub-pixel regions respectively, wherein each TFT has a gate electrode electrically connected to a corresponding gate line, a source electrode electrically connected to the data line, and a drain electrode. The three pixel electrodes are disposed in the three sub-pixel regions respectively, and each pixel electrode is electrically connected to the drain electrode of one TFT respectively. The common line crosses the gate lines and partially overlaps the three gate lines, and the common line and the three pixel electrodes are partially overlapped to respectively form three storage capacitors.

  • Publication number: 20090179875
    Abstract: A flat display includes a substrate, multiple data lines, multiple scan lines, a source driving unit and a gate driving unit. The substrate includes a pixel array. The data lines are electrically connected to the pixel array. The scan lines including p groups of scan lines are electrically connected to the pixel array, wherein p is a positive integer. Some of the scan lines in the same group are not adjacent to each other. The source driving unit is electrically connected to the data lines. The gate driving unit includes p shift register circuits respectively enabling the p groups of scan lines. In a first frame period, p groups of scan lines are enabled according to a first sequence of groups, and in a second frame period, p groups of scan lines are enabled according to a second sequence of groups which is different from the first sequence of groups.
