Problems solved by technology

[0005] In another way, the fingerprint identification module is arranged on the back of the display device (that is, the side opposite to the display screen), which will increase the thickness of the display device, which is not conducive to the thinning and thinning of the display device, and reduces the user's convenience. Experience
[0006] Moreover, in the above two methods, an additional fingerprint chip needs to be installed in the display device to process the signal of the fingerprint identification module, which further increases the cost of the display device.

Abstract

The invention discloses a display panel and a display device, belonging to the technical field of display, comprising: a display area and a non-display area surrounding the display area; the display panel includes a plurality of fingerprint identification modules, and the fingerprint identification modules include a fingerprint identification unit and a signal switching unit , signal wiring; the fingerprint recognition unit is located in the display area; the signal switching unit includes a first input end, a first output end and a second output end; the first input end is electrically connected with the signal wiring, and the first output end and the fingerprint recognition unit Electrical connection, the second output terminal is electrically connected to the conductive electrode; in the fingerprint identification stage, the first input terminal and the first output terminal are connected, and the first input terminal and the second output terminal are insulated; in the display phase, the first input terminal and the first output terminal are electrically connected. The first output terminal is insulated, and the first input terminal and the second output terminal are connected. Compared with the prior art, it is beneficial to realize a full screen and to reduce the thickness of the display panel.

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] In a display device provided in the prior art, a fingerprint recognition function is integrated. When using the display device, the user can use the fingerprint identification function to make the display device perform a specific function. The fingerprint identification function is convenient, fast, and highly secure, and is one of the important research and development directions of the display device. [0003] In the prior art, two ways of setting the fingerprint identification module are provided. [0004] In one way, the fingerprint recognition module is placed under the display screen, which will occupy more space on the display device, which is not conducive to improving the screen ratio and the display effect of the full screen. [0005] In another way, the fingerprint identification ...
