  • Publication number: 20170039918
    Abstract: A display panel is provided. The display panel includes a plurality of data lines and a sub-pixel array. The sub-pixel array includes a plurality of pixel units. The pixel units are arranged along a first direction or a second direction, the first direction is inclined at a first angle relative to a column direction, and the second direction is inclined at a second angle relative to the column direction. Each of the pixel units includes a plurality of sub-pixels respectively corresponding to three different colors and adjacently arranged in a row direction. Each of the data lines is coupled to a first sub-pixel unit at a side of the data line along the column direction and a second sub-pixel unit at another side of the data line along the column direction. The first sub-pixel unit and the second sub-pixel unit are located in different rows.

  • Publication number: 20140292675
    Abstract: A control system applied to touch and capable of switching two-dimensional (2D)/three-dimensional (3D) mode includes a timing controller, a liquid crystal barrier controller, a backlight controller, and a backlight driving unit. The timing controller receives an image signal and a 2D/3D switching signal from a host, receives a touch signal from a touch panel, and generates a first timing control signal and a second timing control signal. The liquid crystal barrier controller generates and outputs a liquid crystal barrier control signal to the touch panel according to the first timing control signal. The backlight controller generates and outputs a backlight luminance control signal according to the second timing control signal. The backlight driving unit generates and outputs a backlight driving signal to a backlight unit of the touch panel according to the backlight luminance control signal.

  • Publication number: 20130271388
    Abstract: A touch sensing three-dimensional (3D) display device includes a display panel and a touch sensing parallax integrated panel. The touch sensing parallax integrated panel located on the display panel includes a first substrate, a second substrate, a touch sensing structure, a display medium layer, a first parallax electrode layer, and a second parallax electrode layer. The second substrate is disposed opposite to the first substrate. The first substrate is located between the display panel and the second substrate. The touch sensing structure is located on the second substrate. The display medium layer is disposed between the first substrate and the second substrate. The first parallax electrode layer disposed on the first substrate is located between the display medium layer and the first substrate. The second parallax electrode layer disposed on the second substrate is located between the display medium layer and the second substrate.

  • Publication number: 20130044121
    Abstract: An electrophoretic display capable of reducing ghost shadows includes an electrophoretic panel, a pixel gray level recording unit, and a control signal generation unit. The electrophoretic panel includes a plurality of pixels. The pixel gray level recording unit is used for recording gray levels of the plurality of pixels when the electrophoretic panel displays a frame according to an image signal. The control signal generation unit is coupled to the pixel gray level recording unit and the plurality of pixels for providing a first refresh control signal for a first group pixels of the plurality of pixels and a second refresh control signal different from the first refresh control signal for a second group pixels of the plurality of pixels according to the gray levels of the plurality of pixels when the electrophoretic panel refreshes the frame according to the image signal.

  • Publication number: 20110084971
    Abstract: An adaptive frame rate modulation system and method thereof are described. A frame processing unit is employed to receive a first frame and a second frame for dividing the second frame into a plurality of second block frames. A frame change detection unit compares the first block frames with the second block frames correspondingly for detecting the change status between the first and second frames. A timing generator classifies the second block frames of the second frame to construct a plurality of frame rates based on the compared results of the first and second block frames. The timing generator further modulates the frame rates of the second frames.
