  • Patent number: 9105253
    Abstract: A liquid crystal display (LCD) device is disclosed. The LCD device comprises a plurality of pixel units arranged in the form of a matrix. Each of the pixel units comprises: a scan line; a data line; a first storage capacitor; a liquid crystal capacitor; and a first TFT, having a source electrically connected to the data line, a gate electrically connected to the scan line, and a drain electrically connected to the first storage capacitor. Each of the pixel units further comprises a second TFT, having a gate, a source electrically connected to the drain of the first TFT, and a drain electrically connected to the liquid crystal capacitor. The gates of the second TFTs are electrically connected with each other to control the second TFTs to be turned on simultaneously so as to tilt the liquid crystal molecules. Because this shortens the time to wait for scanning of the gates is shortened and increases the time duration in which the backlight can emit light, the number of LEDs can be reduced to lower the cost.

  • Publication number: 20140370632
    Abstract: The present invention discloses a TFT, an LCD panel and method for manufacturing the same. In the LCD panel, a transparent conducting layer forms a first electrode of a TFT and a second electrode of a TFT directly, and the transparent conducting layer also serves as a connecting line between a TFT and a data line and between a TFT and an LC capacitor. So it is not necessary to form a via hole over the TFT to link the TFT and the transparent conducting layer. In this way, an area of a pixel electrode can be further extended, and the aperture rate of an LCD panel can be also increased, raising a transmittance of light from light sources passing through the pixel electrode In this way, not only a design in pixels becomes more flexible but also the aperture rate of an LCD panel becomes higher.

  • Publication number: 20140354913
    Abstract: An LCD panel and method for forming the same are proposed. In the LCD panel, the TFT includes a source and a drain formed by a transparent conducting layer, and a gate formed by a metal layer. The source is electrically connected with a data line through a via hole over the data line. The source connects to the drain via an active layer. Whatever the number of data lines are, each pixel corresponds to an associated via hole, so the number of via holes does not increase, and not reduce the aperture ratio. Therefore, the present invention is proper to a design using more data lines and working in a high frequency. Moreover, the matrix circuitry of LCD is well applied in a display which not only increases a density of data lines to raise the frame rate, but also maintains the aperture ratio and brightness.

    Abstract: A method of white balancing an image includes mapping pixels of the image to a color space diagram. Each of the pixels of the image include a red (“R”), a green (“G”), and a blue (“B”) subvalue. A first central tendency of each of the RGB subvalues of pixels mapped in a first pre-defined region of the color space diagram is determined and a second central tendency of each of the RGB subvalues of pixels mapped in a second pre-defined region of the color space diagram is determined. The first pre-defined region is associated with a first illuminating source and the second pre-defined region is associated with a second illuminating source. RGB values of a white pixel are generated based on the first and second central tendencies.
