    Abstract: The present disclosure relates to a driving method and a driving device of touch display panels, and a touch display. The driving method includes: detecting a voltage potential of at least one pixel electrode within the areas of the touch display panel corresponding to different touch scanning partitions, negating the voltage potential, overlapping the negated voltage potential and feed-backed touch pulse signals, and adopting overlapped signals to be the detected touch pulse signals. With the configuration of the touch scanning partitions, the voltage potentials of the pixel electrodes within each of the areas are adopted to respectively adjust the feed-backed touch pulse signals such that the display scanning and the touch scanning can be conducted simultaneously. The detection precision of the touch pulse signals may be enhanced without affecting the display performance.

    Abstract: The present disclosure relates to a display component and a circuit component of display devices. The display component includes a display panel having a display area and an assembly area, a flexible circuit board, a display driving circuit configured within the assembly area or the flexible circuit board for processing the display signals so as to drive the backlight component of the display panel. One end of the flexible circuit board being fixed within the assembly area, and the other end of the flexible circuit board connecting to the host to input the display signals. With such configuration, the manufacturing efficiency of display components and display devices may be enhanced while the dynamic backlight adjustment may be realized.

    Abstract: The present disclosure relates to a driving method and a driving device of display panels. The driving method includes: dividing a saturation interval of an original image frame to be displayed by a display panel into a plurality of sub-saturation intervals; obtaining saturation values corresponding to each of the pixels in the original image frame; calculating numbers of pixels in the original image frame falling within each of the sub-saturation intervals in accordance with the saturation values corresponding to each of the pixels. In this way, the backlight brightness outputted by the backlight module may be adjusted in accordance with the saturation values of the original image frame so as to enhance the low brightness issue when a pure-color image is displayed by the display panel configured with RGBW sub-pixels.
