Abstract: A display module and a driving method thereof, and a display device are provided. The display module includes a backlight structure including a plurality of backlight partitions. The display module includes a first display mode and a second display mode. Resolution of the display module in the first display mode is greater than the resolution of the display module in the second display mode. In the first display mode, a quantity of the plurality of backlight partitions of the backlight structure is n1, and an area of one of the plurality of backlight partitions of the backlight structure is S1. In the second display mode, the quantity of the plurality of backlight partitions of the backlight structure is n2, and the area of one of the plurality of backlight partitions of the backlight structure is S2, with n1>n2, and S1

Abstract: A touch control display panel and a touch control display device are provided. The touch control display panel comprises a plurality of first and second touch control sensing electrodes; a plurality of first and second touch control sensing signal lines; and a first integrated circuit. The first integrated circuit has a longer distance to the first touch control sensing electrode than to the second touch control sensing electrode. R1 and R2 satisfy a predetermined relationship, such that touch control sensing signals respectively outputted by the first touch control sensing signal line and the second touch control sensing signal line exhibit substantially same signal delay time. R1 is a total resistance of the first touch control sensing electrode and the electrically connected first touch control sensing signal line, and R2 is a total resistance of the second touch control sensing electrode and the electrically connected second touch control sensing signal line.

Abstract: A display panel and a display apparatus are provided. The display panel includes a display area. The display area includes color pixels and pixel groups. The color pixels include a first pixel, a second pixel and a third pixel that have different colors from one another, each of the pixel groups includes one first pixel, one second pixel, one third pixel and at least one color-changing pixel. An operating state of the at least one color-changing pixel includes a transparent state and a black state. The display panel provided by the present disclosure can achieve a transparent display effect, and can also display black pixel information in an image by using a black state of the color-changing pixel, which solves the technical problem in the related art in which transparent display is difficult to display black pixel information in the image.
