  • Publication number: 20180080973
    Abstract: The present disclosure provides a gate driving circuit, a method for detecting the gate driving circuit, an array substrate and a display apparatus. The gate driving circuit comprises a plurality of cascaded gate driving units, access units, a first signal line and a second signal line. Each access unit is connected to its corresponding gate driving unit and the gate driving unit at the next stage to its corresponding gate driving unit. The access unit corresponding to the gate driving unit at each odd stage is connected to the first signal line such that the first signal line detects an output signal from that gate driving unit via the access unit, and the access unit corresponding to the gate driving unit at each even stage is connected to the second signal line such that the second signal line detects an output signal from that gate driving unit via the access unit.

  • Publication number: 20170193935
    Abstract: Polarity reversion driving method and apparatus of liquid crystal display and a liquid crystal display are provided. In the method, four frames constitute one polarity reversion driving period, in which a first frame and a third frame have a same polarity arrangement with reversed polarities; a second frame and a fourth frame have a same polarity arrangement with reversed polarities; the first frame and the second frame have different polarity arrangements and corresponding pixels in adjacent two frames have complementary charging effects. The apparatus includes a time schedule controller, a logic controller and a source driver. Charging effects of pixels in frames are controlled by setting a polarity arrangement of pixels in each frame so that charging effects of corresponding pixels are complementary in adjacent two frames, thereby relieving the problem of reduced display quality due to inconsistent charging effects of pixels on two sides of data lines.

  • Patent number: 9478196
    Abstract: Embodiments of the present invention disclose a display method and a display device. 2D display is performed when an input source signal is a 2D image signal, and 3D display or 2D display is performed according to requirements and preferences of a user when the input source signal is a 3D image signal. Problems of blinking and tailing which are present in an existing display device are resolved, an edge blur phenomenon of images for fast motion pictures is illuminated, the “illusion” which is formed due to a visually temporary retention of human eyes is corrected, and picture stability is effectively improved; and a crosstalk phenomenon caused by simultaneous displaying of the left-eye image and the right-eye image in an existing active 3D technology is eliminated.
