Abstract

The invention discloses a display panel and a display device, and relates to the technical field of display, the display panel comprises a drive circuit, wherein the drive circuit comprises N stages of shift registers cascaded with each other, and N is greater than or equal to 2; each shift register includes: a first control unit; a second control unit; a third control unit; and a fourth control unit which is used for receiving the third voltage signal and the fourth voltage signal and generating an output signal in response to the signal of the second node and the signal of the fourth node, wherein the third voltage signal is a high-level signal, the fourth voltage signal is a low-level signal, the potential of the first voltage signal is higher than the potential of the third voltage signal, and / or the potential of the second voltage signal is lower than the potential of the fourth voltage signal. The shift register solves the problem that a shift register in the prior art cannot meet different voltage requirements of a pixel circuit for different signals.

Description

technical field [0001] The present invention relates to the field of display technology, and more particularly, to a display panel and a display device. Background technique [0002] At present, display technology is widely used in television, mobile phones and display of public information, bringing great convenience to people's daily life and work. In the prior art, a scan driving circuit is required to provide a driving signal to the pixel circuit in a display panel for displaying a picture, so as to control the display panel to realize the function of scanning, so that the image data input to the display panel can be refreshed in real time, thereby Realize dynamic display. [0003] However, the existing scanning driving circuit cannot meet the different voltage requirements of the pixel circuit for different signals. Contents of the invention [0004] In view of this, the present invention provides a display panel and a display device to solve the problem that the sh...
