Embodiment Construction
[0062] Certain terms are used, for example, in the description and claims to refer to particular components. Those skilled in the art should understand that hardware manufacturers may use different terms to refer to the same component. The specification and claims do not use the difference in name as a way to distinguish components, but use the difference in function of components as a criterion for distinguishing. As mentioned throughout the specification and claims, "comprising" is an open term, so it should be interpreted as "including but not limited to". "Approximately" means that within an acceptable error range, those skilled in the art can solve the technical problem within a certain error range and basically achieve the technical effect. In addition, the term "coupled" herein includes any direct and indirect electrical coupling means. Therefore, if it is described that a first device is coupled to a second device, it means that the first device may be directly elect...

The present application discloses a display panel and a display device, which are provided with a display area and a non-display area surrounding the display area, wherein the display panel includes: a first substrate, including a plurality of pieces of data extending along a first direction and arranged in a second direction Signal line; second substrate, set opposite to the first substrate; multiple fingerprint identification units, arranged in the display area, the fingerprint identification unit includes fingerprint identification driving electrodes and fingerprint identification sensing electrodes, and the fingerprint identification driving electrodes are arranged on the first substrate Above, the fingerprint identification sensing electrodes are arranged on the second substrate; the fingerprint identification driving electrodes include a plurality of data signal lines. In this way, the frame width of the display device is reduced, which is beneficial to realize the narrow frame design of the display device, and the fingerprint recognition drive electrode of the present application multiplexes the data signal lines in the display panel, which reduces the process of separately manufacturing the fingerprint recognition drive electrode and simplifies While improving the manufacturing process, it is also beneficial to reduce the cost and reduce the overall thickness of the display device.
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] With the continuous development of electronic equipment, fingerprint identification has become a major selling point of electronic equipment. Currently, common fingerprint identification devices are usually optical fingerprint sensor devices and semiconductor fingerprint sensor devices. Optical fingerprint sensors are usually bulky and their applications are limited. The semiconductor fingerprint sensing device has the advantages of low price, small size and high recognition rate, and is more and more used in various electronic devices. [0003] The combination of the semiconductor fingerprint sensing device and the display device will undoubtedly bring a series of advanced functions, for example, the fingerprint recognition device can be used to safely perform operations such as turning on and off ...
