  • Patent number: 10365494
    Abstract: An adjustment structure of a bridle including a bridle, rotating shaft, and a knob is provided. The bridle has a rack. The rotating shaft has a first ring gear and a second ring gear both around an axis, wherein the first ring gear is coupled to the rack, such that the rotating shall moves along the bridle by rotating about the axis itself. The knob is rotated about the axis and moved along the axis to be movably coupled to the rotating shaft. The knob has a third ring gear to be engaged with or released from the second ring gear by the knob moving along the axis. When the third ring gear is engaged with the second ring gear, the knob is forced to drive the rotating shaft to rotate about the axis.

  • Publication number: 20140198021
    Abstract: A display driving apparatus, including an image processor, a timing controller, and a plurality of source drivers, is provided. The image processor determines whether an image frame corresponding to a frame data is a static image and outputs the frame data and a determination result. The timing controller receives the frame data from the image processor and outputs the frame data. The source drivers receive the frame data from the timing controller and drive a display panel according to the frame data. Each of the source drivers includes a memory module configured to store the frame data corresponding to the static image. When the source drivers drive the display panel according to the frame data corresponding to the static image, the image processor stops outputting the frame data to the timing controller, and the timing controller stops outputting the frame data to the source drivers.
