    Abstract: Provided are a scanning driving circuit and a liquid crystal display device. The scanning driving circuit comprises multiple cascaded scanning driving units (1). Each scanning driving unit (1) comprises an input module (100) for outputting a low-level signal and a plurality of driving circuits (200). Each driving circuit (200) corresponding drives one scanning line. Each driving circuit (200) comprises: a control module (210), for outputting a control signal according to the received low-level signal; an output module (220), and a pull-down module (230), for being connected or cut off according to the received control signal; scanning lines (G(N−1), G(N), G(N+1)), for outputting a high-level or low-level scanning driving signal to pixel units. When the output module (220) is cut off, the pull-down module (230) is connected, and the scanning lines (G(N−1), G(N), G(N+1)) output the low-level scan driving signals to the pixel units; and when the output module (220) is connected, the pull-down module (230) is cut off, and the scanning lines (G(N−1), G(N), G (N+1)) output high-level scanning driving signals to the pixel units. Accordingly, a circuit of the liquid crystal display device is simplified, and the space is saved, thereby facilitating the narrow-frame design of the liquid crystal display device.

    Abstract: The present invention provides a driving method for a display panel. In an n-th scanning period, the pixel unit on the i-th row and an x-th column receives data signals. At least two subpixels with different colors on the i-th row and the x-th column of pixel unit receive the data signals according to a first sequence. In an (n+1)th scanning period, the pixel unit on the j-th row and an x-th column receives data signals. At least two subpixels with different colors on the j-th row and the x-th column of pixel unit receive the data signals according to a second sequence. A color of the subpixel which last receives the data signal in the first sequence is the same as a color of the subpixel which first receives the data signal in the second sequence.

    Abstract: A display pixel structure includes a plurality of pixel units arranged in an array. Each of the pixel units comprises the first sub-pixel, the second sub-pixel, the third sub-pixel and the fourth sub-pixel. Each of the sub-pixels includes a TFT switch. A ratio between a width/length ratio of the TFT switch of one of the first sub-pixel, the second sub-pixel, and the third sub-pixel or an average of width/length ratios of multiple TFT switches thereof and a width/length ratio of the TFT switch of the fourth sub-pixel is equal to a ratio between a storage capacitance of one of the first sub-pixel, the second sub-pixel, and the third sub-pixel or an average of multiple storage capacitances thereof and a storage capacitance of the fourth sub-pixel. An array substrate and a liquid crystal display device are also disclosed.
