Display panel and display device

Abstract

The embodiment of the invention discloses a display panel and a display device. The display panel comprises a fingerprint identification unit, Q first gate drive circuits, a drive chip, a first decoding circuit and M first signal lines, wherein the driving chip comprises M first signal output ends; the first decoding circuit comprises M first signal input ends, a second signal input end and N signal output ends; the first signal output end and the first signal input ends are electrically connected through first signal lines; the second signal output end and the second signal input end are electrically connected through a second signal line; each first gate drive circuit is connected to a signal output end; the first signal output end outputs a pulse signal, and the pulse signal comprises a first level signal and a second level signal; the second signal output end outputs a third level signal, the potential of the first level signal is higher than that of the second level signal, and the potential of the second level signal is higher than that of the third level signal. Therefore, the width of the frame can be reduced.

Description

technical field [0001] Embodiments of the present invention relate to the field of display technology, and in particular, to a display panel and a display device. Background technique [0002] With the development of science and technology, it has become a development trend to integrate more and more functions in display devices. For example, there are many display devices with fingerprint recognition functions on the market, such as mobile phones, tablet computers and smart wearable devices. . [0003] With the increase of application scenarios of the fingerprint recognition function, the fingerprint recognition area is gradually advancing from partial areas to full-screen fingerprint recognition. In the existing full-screen fingerprint identification technology, the fingerprint identification unit is usually divided into partitions in the display device, and the fingerprint identification units in different areas are driven by different driving circuits, and at least one ...

AI Technical Summary

Problems solved by technology

In the existing full-screen fingerprint identification technology, the fingerprint identification unit is usually partitioned in the display device, and the fingerprint identification units in different areas are driven by different driving circuits, and at least one signal signal is provided between each driving circuit and the driving chip. line, resulting in a wider frame of the display device, which is not conducive to the realization of a narrow frame
