  • Patent number: 10665185
    Abstract: A drive circuit for driving a display panel includes a dynamic refresh unit, a timer, and a black insertion drive unit. The dynamic refresh unit is configured to output a dynamic refresh signal, so as to control the display panel to display a plurality of frames in sequence. A frame time of each of the frames is adjusted according to the dynamic refresh signal. The timer is configured to compute a black insertion time signal. The black insertion drive unit is configured to output a black insertion drive signal according to the black insertion time signal, so as to perform black insertion on the frames.

  • Patent number: 10591770
    Abstract: A display device comprising a color filter layer and a light-emitting unit is provided. The color filter layer includes a first subpixel area, a second subpixel area and a third subpixel area. The first subpixel area includes a first quantum dot material, and the second subpixel area includes a second quantum dot material. The light-emitting unit provides light to the color filter layer. A wide color gamut and a polarization effect are achieved via the quantum dot materials and the polarization material. Furthermore, due to no additional loss of the light at the light-emitting unit (backlight module), the luminous efficiency is high.

  • Publication number: 20160034084
    Abstract: A touch display device is provided. The touch display device includes a display panel and a touch panel. The display panel displays a display image with a linear-polarized state, and includes an upper polarizer with a transmission axis. The touch panel is disposed on the display panel. The touch panel includes a substrate with a fast axis. The display image is converted from the linear-polarized state to the circular-polarized state when the passing through the fast axis. A touch display device having a plurality of substrates is provided. Since the substrate having the fast axis replaces the original substrate of the touch panel without adding an additional substrate, the touch display device is thinner.

  • Patent number: 8670102
    Abstract: A display panel includes an active device array substrate, an opposite substrate, and a liquid crystal layer. The active device array substrate includes a substrate and further includes a pixel array, signal lines, and first and second repairing lines all disposed on the substrate. The signal lines electrically connect the pixel array. The first repairing line includes first and second line segments respectively located on first and second sides of the pixel array. The first side is substantially perpendicular to the second side. The first and second line segments are electrically connected. The second repairing line includes third and fourth line segments respectively located on third and second sides of the pixel array. The third side is substantially parallel to the first side. The fourth and third line segments are electrically connected. The opposite substrate above the active device array substrate does not cover the first and third line segments.

  • Publication number: 20130033749
    Abstract: A stereo display device includes a display panel and a switching panel. The display panel has a plurality of unit regions, and each of the unit regions includes a right eye unit region and a left eye unit region. The switching panel is disposed on the display panel and includes a first substrate, a second substrate, a plurality of electrode patterns and an optically anisotropic medium. The first substrate and the second substrate are disposed opposite to each other. The electrode patterns are disposed on the second substrate. The optically anisotropic medium is disposed between the first substrate and the second substrate.
