Problems solved by technology

For some large-screen display devices, due to the long lines used to provide various signals, it is easy to cause signal delay, thus affecting the display effect of the display device
[0003] At present, in order to solve the above-mentioned signal delay caused by long lines, the usual method is to increase the width-to-length ratio of the buffer in the driving circuit to improve the driving capability of the driving circuit, but the frame of the screen cannot be further narrowed, making it difficult to Adapt to the development trend of narrow edge screen

Abstract

The invention discloses a display panel and a display device, comprising: a display area and a non-display area located around the display area; the display area includes a plurality of scanning lines extending along a first direction; the non-display area includes two first drive units and at least one second driving unit, the two first driving units are located on opposite sides of the display area; wherein, the first driving unit is arranged opposite to the display area in the first direction, and the second driving unit is arranged opposite to the display area in the second direction The regions are arranged oppositely; the second drive unit includes a plurality of second shift registers, and the output end of each second shift register is electrically connected to at least one scanning line through a connection line. Compared with the prior art, by providing the second driving unit, the driving capability of the scanning line can be effectively improved without occupying the non-display area where the first driving unit is located, which is beneficial to realize narrower frame of the display device.

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] With the continuous development of display technology and the continuous improvement of people's requirements for visual effects, narrow bezel screens have increasingly become the mainstream of display devices. For some large-screen display devices, since the lines used to provide various signals are long, it is easy to cause signal delay, thereby affecting the display effect of the display device. [0003] At present, in order to solve the above-mentioned signal delay caused by long lines, the usual method is to increase the width-to-length ratio of the buffer in the driving circuit to improve the driving capability of the driving circuit, but the frame of the screen cannot be further narrowed, making it difficult to Adapt to the development trend of narrow edge screen.
