    Abstract: A driving circuit for a display panel is disclosed. The driving circuit includes at least a driving signal line connected to a display driving signal transmission unit delivering display driving signal produced by the display driving signal transmission unit to sub-pixels of the display panel through the driving signal line; and a number of data signal lines connected to a display data provision unit delivering display data signal produced by the display data provision unit to the sub-pixels. For each subset of the sub-pixels that are of a same component color, at least two data signal lines, starting from different points of time, deliver display data signal to the subset of sub-pixels that are of the same component color. The driving circuit effectively resolves glitches to input signal resulted from heavy transient load to the input signal.

    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: 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 display panel and an array substrate including a plurality of pixel cells including colorful sub-pixels and one white sub-pixel. Each of the sub-pixels includes at least one sub-pixel electrode and at least one sub-pixel transistor corresponding to each of the sub-pixel electrode. The sub-pixel transistors are configured within the white sub-pixel to enhance an aperture rate of the colorful sub-pixels. As the sub-pixel transistors are configured within the same white sub-pixel, the brightness of the white sub-pixel may be decreased. At the same time, the aperture rate of the colorful sub-pixels may be greatly enhanced so as to enhance the performance of colorful images.
