Abstract

The embodiment of the invention discloses a display device. The display device comprises a display functional layer, a fingerprint identification module, at least one functional layer and at least one adhesive layer, wherein the display function layer comprises a first area and a bending area which are arranged in the first direction, and the first area comprises a first sub-area; at least one functional layer comprises at least one first functional layer, at least one adhesive layer comprises at least one first adhesive layer, the first functional layer is in contact with the first adhesive layer, and one side, facing the first adhesive layer, of the first functional layer is provided with at least one first groove; the orthographic projection of the first groove on the plane where the display function layer is located is located between the first sub-area and the bending area, so that the probability that the parallel relation between the first sub-area of the display function layer and the binding face of the fingerprint recognition module is damaged in the repeated bending process of the display device is reduced, and the fingerprint identification precision of the fingerprint identification module based on the received light or sound wave characteristics is improved.

Description

technical field [0001] The present application relates to the field of display technology, and in particular to a display device. Background technique [0002] With the development of display technology, the application of display devices has become more and more extensive, and has gradually become an indispensable electronic product used in people's daily work and life. Correspondingly, the user privacy information stored in existing display devices is also increasing. more. [0003] In order to improve the security of display devices, more and more display devices integrate fingerprint recognition functions, but the fingerprint recognition rate of existing foldable display devices integrated with fingerprint recognition functions drops rapidly during use. Contents of the invention [0004] In order to solve the above problems, the embodiment of the present application provides the following technical solutions: [0005] A display device, comprising: a display functiona...
