    Abstract: The present invention provides a source driving circuit and an LCD device. The source driving circuit includes output channels, and each output channel includes a first switch element, a second switch element, a first output end, and a second output end. The first switch element and the second switch element are respectively connected to the first output end and the second output end. When the first switch element is turned on, the output channel outputs a display signal, and when the second switch element is turned on, the output channel provides recycled charges which are generated when the display signal is changed from a positive voltage to a negative voltage. The source driving circuit can recycle charges to make the most of charges generated when the display signals change from positive voltages to negative voltages and reduce power consumption of the LCD device.

  • Patent number: 8649634
    Abstract: A device and a method for image zooming are provided, in which two FIFO buffer units and a read/write control unit are added between a data storage unit and an image zooming unit. The read/write control unit respectively controls two FIFO buffer units to obtain and output the gray values of the pixels on the two adjacent channels to the image zooming unit in parallel. Then, the image zooming unit calculates gray values of pixels to be inserted between the two adjacent channels to finish interpolation. The image zooming unit need not read the gray values of the pixels on the two adjacent channels in the zooming direction from the data storage unit in series and in turn, but instead, may simultaneously read the gray values of the pixels on the two adjacent channels to pixels to be inserted from the two FIFO buffer units in parallel.

  • Patent number: 8427746
    Abstract: The present invention discloses a stereoscopic image display system and a method of controlling the same. An eye tracking module locates current 3D spatial positions of the viewer's eyes, and generates the information of both left and right eyes' current 3D spatial positions. A control module controls a display device that can alter the direction of the light outputted, and outputs images on the display device in time multiplex mode. The light containing the left eye image is outputted to the position of left eye instead of right eye at one time point, and the light containing the right eye image is outputted to the position of right eye instead of left eye at another time point, so that a stereoscopic image is perceived according to the parallax theory. The present invention enlarges the visual range of stereoscopic image and achieves a better stereoscopic image visual experience for viewers.
