Abstract

The invention discloses a display panel and a display device. An Nth auxiliary unit of the display panel is located in a display area of the display panel; the output end of the Nth auxiliary unit is connected with an Nth scanning line; and since the auxiliary unit in the display area is connected with the corresponding scanning line, the falling edge of the scanning signal transmitted in the scanning line can be rapidly pulled down or the rising edge of the scanning signal can be rapidly pulled up, and the problem of scanning signal distortion caused by transmission delay in the display area can be relieved.

Description

technical field [0001] The present application relates to the field of display technology, in particular to a display panel and a display device. Background technique [0002] As a display component of electronic equipment, display devices have been widely used in various electronic products. Among them, various driving modules are an important part of the display device, and most of them are located in the peripheral area of ​​the display device. Drive signals need to be transmitted through drive signal lines. to the display area of ​​the display device. [0003] With the continuous development of current display applications, the appearance and size of display panels are constantly breaking through. More and more application scenarios have more and more diverse demands on display panels. However, as the size of the display panel continues to expand, the transmission delay of these driving signals is also increasing, and the distortion of the driving signals is also becom...
