    摘要： A driving circuit of a display panel and a driving method thereof are disclosed. The display panel includes multiple data lines and fan-out traces connected to the multiple fan-out traces in one-to-one correspondence. The driving circuit includes multiple compensation circuits and a signal input unit. Each compensation circuit includes an input terminal and an output terminal. The output terminals of the multiple compensation circuits are respectively connected to the plurality of fan-out traces. At least two gear positions are set in each compensation circuit. When the gear position of the compensation circuit increases, a capacitance value or a resistance value of the compensation circuit gradually decreases. The signal input unit outputs data signals to the input terminals of the multiple compensation circuits. Each compensation circuit selects a gear position depending on a gray scale of a data signal or a scanning time during progressive scanning of the display panel.

    摘要： A semiconductor device where delay or distortion of a signal output to a gate signal line in a selection period is reduced is provided. The semiconductor device includes a gate signal line, a first and second gate driver circuits which output a selection signal and a non-selection signal to the gate signal line, and pixels electrically connected to the gate signal line and supplied with the two signals. In a period during which the gate signal line is selected, both the first and second gate driver circuits output the selection signal to the gate signal line. In a period during which the gate signal line is not selected, one of the first and second gate driver circuits outputs the non-selection signal to the gate signal line, and the other gate driver circuit outputs neither the selection signal nor the non-selection signal to the gate signal line.

    摘要： According to an aspect of the present disclosure, a display device includes a display panel having a display area and a non-display area adjacent to the display area, where the display area includes a plurality of pixels. The display device further includes a gate driver disposed in the non-display area of the display panel and configured to supply a gate signal to the plurality of pixels, and a data driver configured to supply a data voltage to the plurality of pixels and configured to supply a clock signal to the gate driver through a clock line. The display device also includes a clock pseudo line disposed in the non-display area of the display panel and applied with a clock pseudo signal with a phase inverted from a phase of the clock signal. By this configuration, the electromagnetic interference by the clock signal cancan be effectively removed or minimized.

    摘要： An array substrate, a display panel and a display device. The array substrate includes multiple pixel groups arranged in an array, each pixel group includes two sub pixel groups, each sub pixel group includes two pixels, and each pixel includes multiple sub-pixels. The sub-pixels in a same pixel group are located in a same row. Pixel groups in the same row are correspondingly connected to two adjacent scan lines, and pixel groups in different row are connected to different scan lines. In a same sub pixel group, sub-pixels having a same color and opposite polarities are connected to a same source driver IC, and are connected to different scan lines. In a same pixel group, sub-pixels having a same color and opposite polarities in different sub pixel groups are connected to the same scan line.
