The present disclosure provides a display panel and a display device, comprising: a flexible base substrate comprising a first flexible substrate, a second flexible substrate, and metal signal lines located between the first flexible substrate and the second flexible substrate; a display unit disposed on the flexible base substrate; a touch unit disposed on a light-exiting side of the display unit and covering the display unit; and a processing chip connected to the flexible base substrate for receiving and feeding back signals from the display unit and/or the touch unit. The metal signal lines are electrically connected to the processing chip and the touch unit transmits a touch signal to the metal signal lines through a conductive adhesive. By transmitting the touch signal to the processing chip through the conductive adhesive, the touch unit and the display unit can share one processing chip.

A display panel includes multiple scanning lines, sub-pixels and a scanning drive circuit. The sub-pixels include first sub-pixels, second sub-pixels and third sub-pixels. Each scanning line connects to sub-pixels of one same type of emission. The first sub-pixels include a first group and a second group, and the third sub-pixels include a first group and a second group. The scanning drive circuit is used for driving a fraction of the sub-pixels in one frame. In odd frames, only first group of the first sub-pixels, and the third sub-pixels, and the second sub-pixels are driven to emit light in odd frames. In even frames, only second group of the first sub-pixels and the third sub-pixels, and the second sub-pixels are driven to emit light. When the display screen is refreshed, the number of the sub-pixels driven to emit light is reduced, and power of charging and discharging of the sub-pixels is reduced.
