Embodiment 1

[0048] figure 1 It is a schematic structural diagram of a display device for under-screen fingerprint recognition provided by Embodiment 1 of the present invention. figure 2 It is a schematic structural diagram of a support layer of a display device for under-display fingerprint recognition provided by Embodiment 1 of the present invention.

[0049]The inventor of the present invention found in the actual research process that in the current under-screen fingerprint recognition technology, the fingerprint recognition device is usually arranged on the back of the display screen, and a plurality of small holes for light transmission are opened in the display screen, and the fingerprint The identification device is arranged opposite to the light-transmitting small hole, and can receive the light transmitted through the light-transmitting small hole. During the fingerprint identification process, when the user's finger touches the display screen, the fingerprint of the finger wi...

Embodiment 2

[0082] image 3 It is a schematic structural diagram of a support layer of a display device for under-display fingerprint recognition provided by Embodiment 2 of the present invention. refer to image 3 As shown, on the basis of the first embodiment above, the second embodiment of the present invention also provides another structure of the display device for fingerprint recognition under the screen. Compared with the first embodiment, the difference between the two The reason is that the structure of the supporting layer 30 is different.

[0083] Specifically, the support layer 30 is a whole-layer structure, and at least one through hole 33 connecting the display panel 10 and the fingerprint module 20 is opened on the support layer 30 , and a light-transmitting area is formed inside the through hole 33 .

[0084] It should be noted that, in this embodiment, the support layer 30 is provided as a whole-layer structure, which can ensure the support strength of the support laye...

Embodiment 3

[0088] Figure 4 It is a schematic structural diagram of a support layer of a display device for under-screen fingerprint recognition provided by Embodiment 3 of the present invention. refer to Figure 4 As shown, on the basis of the first and second embodiments above, the third embodiment of the present invention also provides another structure of a display device for fingerprint recognition under the screen, and the third embodiment is similar to the first and second embodiments The difference is that the structure of the support layer 30 is different.

[0089] Specifically, the supporting layer 30 is a light-transmitting whole-layer structure.

[0090] It should be noted that, in order to further ensure the support effect of the support layer 30 on the display panel 10, the support layer 30 can be set as a whole layer structure, that is, no channel structure is opened on the support layer 30. At this time, in order to ensure that the support layer 30 has In the light-tra...

Abstract

The invention provides a display device for under-screen fingerprint identification. The display device includes a display panel and a fingerprint module, a support layer is arranged between the display panel and the fingerprint module and extends along the joint face of the display panel and the fingerprint module, and at least part of the support player is located at the joint between the display panel and the edge of the fingerprint module. By adopting the display device for under-screen fingerprint identification, pressure generated when the display panel fits the fingerprint module can beeffectively relieved; the situations are avoided that fingerprint module profile impressions appear on the display panel, and the display panel deforms; the surface flatness and attractiveness of thedisplay panel are improved, the light inlet amount of the fingerprint module is increased, and the fingerprint identification accuracy is improved.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a display device for fingerprint identification under the screen. Background technique [0002] Under-screen fingerprint recognition technology refers to the technology of collecting fingerprints on the front of the display screen through the fingerprint recognition device set on the back of the display screen to complete fingerprint recognition. Since the fingerprint collector is set on the back of the display screen, it can save the front display area to improve user experience. [0003] In the current under-screen fingerprint recognition technology, the fingerprint recognition device is usually arranged on the back of the display screen, and a small hole for light transmission is opened in the display screen, and the fingerprint recognition device can receive the light transmitted through the small hole. When the user's finger touches the display screen, the light reflected ...
