Abstract: A display panel includes: a pixel driving circuit, a base substrate, a second conductive layer, a third conductive layer. The second conductive layer is disposed on a side of the base substrate, includes first signal lines, orthographic projections of the first signal lines extend in a first direction and spaced apart in a second direction, the first direction and the second direction intersect; the third conductive layer is disposed on a side of the second conductive layer away from the base substrate and includes second signal lines, orthographic projections of the second signal lines extend in the second direction and spaced apart in the first direction; the first signal lines and the second signal lines are configured to provide the same first signal to the pixel driving circuit, part of the first signal lines and the second signal lines are coupled through via holes.

Abstract: Embodiments of the present disclosure provide a display panel and a drive method thereof, and a display device. The display panel includes a plurality of sets of pixel columns and a plurality of drive circuits. Each of the sets of pixel columns includes a plurality of subpixel columns. The plurality of drive circuits correspond to the plurality of sets of pixel columns respectively. Each of the drive circuits is further configured to send, to an adjacent drive circuit, a source data signal for the subpixel column in the set of pixel columns of the drive circuit, and/or receive, from the adjacent drive circuit, a source data signal for the subpixel column in the set of pixel columns of the adjacent drive circuit and generate a data signal for driving the subpixel column in the set of pixel columns of the drive circuit, based on the received source data signal.

Abstract: A display panel, a display module and a display method thereof, and a display device are provided. The display module includes a backlight module and a display panel. A driving circuit and a photosensor are provided on the display panel, and the photosensor is electrically connected with the driving circuit. When the backlight module receives a backlight control signal, the backlight module emits light based on a light emission frequency indicated by the backlight control signal, and the backlight control signal is converted from a display signal output from a host. The photosensor detects an optical signal generated by the backlight module, converts the optical signal into an electric signal, and transmits the electric signal to the driving circuit, such that the driving circuit drives the display panel to display an image.
