Embodiment Construction

[0051] In the related art, a fingerprint recognition under the side screen is designed. figure 1 It is a partial structural schematic diagram of a display device in the related art. like figure 1 As shown, the flexible display device includes a flexible curved screen 2 and a housing 1, the flexible curved screen 2 and the housing 1 enclose an accommodating cavity, and the curved display area of ​​the flexible curved screen 2 is provided with a fingerprint recognition module on the side close to the accommodating cavity. Group 3, and the fingerprint identification module 3 is bonded to the flexible curved screen 2 through glue. However, due to the limited support of the fingerprint identification module 3 on the side of the flexible curved screen 2, the flexible curved screen 2 is reduced when it is close to the fingerprint identification module. Structural strength at the bend region 4 of 3. In this way, when the flexible display device vibrates or bends, wrinkles are likely...

Abstract

The invention provides a fingerprint recognition device and a display device, relates to the technical field of fingerprint recognition, and aims at solving the technical problem of poor display of a display panel due to the fact that the strength of the display panel is easily reduced by an existing fingerprint recognition module. The fingerprint recognition device comprises a supporting piece and a fingerprint recognition module arranged on the supporting piece; the supporting piece comprises a first supporting face and a second supporting face which face different directions, the first supporting face is used for abutting against at least part of the side edge of a display panel of the display device, and the second supporting face is used for abutting against the inner side of a bottom shell of the display device; and a containing cavity is formed in the supporting piece, and the fingerprint recognition module is located in the containing cavity. According to the fingerprint recognition device and the display device, the strength of the side edge of the display panel can be improved, the display effect of the display panel is improved, and the reliability of the display device is improved.

Description

technical field [0001] The present application relates to the technical field of fingerprint identification, in particular to a fingerprint identification device and a display device. Background technique [0002] At present, people's awareness of information security protection is gradually strengthening. Based on this, more and more terminal devices adopt fingerprint recognition technology, which is realized by fingerprint recognition sensors. [0003] Due to its excellent information security protection performance and small size, the fingerprint recognition sensor has gradually become the standard configuration of terminal equipment. There are many types of fingerprint recognition sensors. Among them, in the display panel, the optical fingerprint recognition module is the more commonly used one, usually located under the screen body. The principle is that the light emitted by the display device illuminates the finger and is reflected back to the optical detector imaging...
