Abstract: The present disclosure relates to a driving method and a driving device of display panels. The driving method includes: obtaining three-color sub-pixel data of each of pixels of a current image, obtaining a saturation value corresponding to each of the pixels in accordance with the three-color sub-pixel data of each of the pixels, obtaining a current background-white ratio in accordance with the three-color sub-pixel data and the saturation value of each of the pixels, determining whether the current background-white ratio is within a predetermined adjustment range, and reducing a white grayscale value of four-color sub-pixel data of the current image in accordance with the current background-white ratio and outputting the reduced white grayscale value to a display panel. In this way, the darker pure-color effect due to the high contrast may be reduced, which effectively enhances the darker pure-color issue of the RGBW display panel.

Abstract: The present disclosure relates to a driving system of display panels. The driving system includes a main board and a display panel. The main board is configured with a driving chip, and the driving chip electrically connects to the display panel via a flexible circuit board to drive the display panel to display. With such configuration, the driving system is configured with the main board and the driving chip, and the driving chip is arranged on the main board, instead of the flexible circuit board. With such configuration, the space of the display area occupied by the components is reduced so as to realize the narrow border design for a top border and a bottom border of the display panel. In this way, the screen ratio of the display panel is increased.

Abstract: An array substrate includes: a substrate, scan lines, and wires connecting to the scan lines. A gate driver provides scan signals to the scan lines through the wires. The wires extend dispersedly along the direction from the gate driver to the scan lines. The number of amplifiers corresponding to some output channels of the gate driver is different, so that an output drive capability provide to the some output channels of the gate driver is different. The output drive capability of the scan signals provided by the gate driver to the wires is larger if the wires is closer to the edge of the substrate, so that the RC delay are the same when the scan signals pass through the wires. It prevents uneven brightness or color of the displayed images due to different RC delays of scan signals, thus elevates the display quality.
