  • Publication number: 20130307881
    Abstract: According to various embodiments of the invention, gamma curves for multiple pixel groups can be calibrated using look-up tables or by using reference voltage groups provided by gamma voltage generators so that the pixels can display multiple images with correct gray levels at different view angles. Therefore, color shift can be avoided or lessened without necessarily using extra circuitry on the display panel. Also, any related light transmittance or light utilization efficiency reduction may be decreased or eliminated.

  • Patent number: 8362995
    Abstract: A multi-domain LCD panel includes data lines, scan lines and pixels. Each pixel includes first and second sub-pixels respectively having first and second storage capacitors. A first data switch is selectively coupled to a first terminal of the first capacitor and one of the data lines. A second data switch is selectively coupled to a first terminal of the second capacitor and one of the data lines. First and second bias lines are respectively coupled to second terminals of the first and second capacitors. When a corresponding scan line is enabled, the first and second data switches turn on such that a signal on the data line is transmitted to the first and second sub-pixels. After the scan line is disabled, levels of the first and second bias lines are changed such that pixel voltages of the first and second sub-pixels differ from each other.

  • Publication number: 20120162415
    Abstract: The present invention discloses an image-based barrier detection and warning system and a method thereof, wherein an image processing technology is used to establish ROI and verify whether a horizontal line signal exists, and wherein the image processing technology determines whether an object is a barrier via detecting contours of an object and detecting distance to the object, and wherein the system timely outputs warning signals and presents distance to a barrier when detecting the barrier. The image-based barrier detection and warning system enables the driver to watch the surroundings of the vehicle directly and clearly and learn the relative positions of barriers, whereby the driver can park more easily and safely.
