Problems solved by technology

[0004] However, since the infrared light source is arranged in the chin area of ​​the electronic product through the flexible circuit board and the reinforcing plate, the chin area will increase a certain width. Compared with the chin area of ​​the existing electronic product, the increase ratio of the chin area width is relatively high. The screen-to-body ratio of mobile phones is significantly reduced, which hinders the realization of full-screen electronic products

Embodiment 1

[0051] Figure 5 It is a schematic structural diagram of a mobile phone equipped with an under-screen fingerprint recognition device provided in Embodiment 1 of the present application.

[0052] refer to Figure 5 As shown, the embodiment of the present application provides an under-screen fingerprint recognition device, which is applied to electronic equipment with a liquid crystal display screen 20 and a middle frame 10, and includes a detection light source 31 and a fingerprint recognition module 32. The detection light source 31 is located on the liquid crystal display screen 20 Under the edge area of ​​the protective cover 211, the middle frame 10 is used to support the liquid crystal display screen 20, and the middle frame 10 is provided with an accommodation space 111 at a position opposite to the detection light source 31, and the detection light source 31 is at least partly located in the accommodation space 111 And it is attached to the middle frame 10; the fingerpr...

Embodiment 2

[0094] Figure 6 It is a schematic diagram of the assembly of a detection light source and a middle frame provided in Embodiment 2 of the present application. Figure 7 It is a schematic diagram of the assembly of another detection light source and the middle frame provided in Embodiment 2 of the present application.

[0095] On the basis of the first embodiment above, refer to Figure 6 and Figure 7 As shown, since at least part of the detection light source 31 is embedded in the middle frame 10, in order to avoid the detection light in the light-emitting area of ​​the detection light source 31 being blocked by the middle frame 10, the light-emitting area of ​​the detection light source 31 is located near the fingerprint recognition area 214 of the detection light source 31. side, so that the detection light in the light-emitting area can emit out of the middle frame 10, which is used to increase the intensity of the detection light irradiated on the finger.

Embodiment 3

[0103] Figure 8 It is a schematic structural diagram of a mobile phone equipped with an under-screen fingerprint recognition device provided in Embodiment 3 of the present application.

[0104] On the basis of the first and second embodiments above, when the frame 11 of the middle frame 10 adopts an arc-shaped frame, as described in the above-mentioned embodiment, the thickness of the arc-shaped frame near the protective cover 211 is only 0.6mm. The accommodating space 111 cannot be opened, and the thickness of the middle part of the frame is about 1.3 mm. Therefore, the opening of the accommodating space 111 needs to be close to the middle part of the frame 11 . Since the accommodating space 111 is close to the middle of the frame 11 of the middle frame 10, compared with the prior art, the detection light source 31 is directly arranged on the chin area of ​​the mobile phone 100 (such as image 3 As shown), the distance between the detection light source 31 and the protectiv...

Abstract

The invention provides an under-screen fingerprint identification device and electronic equipment. The under-screen fingerprint identification device is applied to electronic equipment with a liquid crystal display screen and a middle frame. The under-screen fingerprint identification device comprises a detection light source and a fingerprint identification module, the detection light source is located below the edge area of the protection cover plate of the liquid crystal display screen, a containing space is formed in the position, opposite to the detection light source, of the middle frame, and at least part of the detection light source is located in the containing space and attached to the middle frame so that the increasing width of the jaw area of the electronic equipment can be reduced, and implementation of a full screen of the electronic equipment is facilitated.

Description

technical field [0001] The present application relates to the field of display technology, in particular to an under-screen fingerprint identification device and electronic equipment. Background technique [0002] Smartphones have entered the era of full screens, and the screen-to-body ratio of mobile phones is getting larger and larger. The fingerprint recognition technology under the screen has become a trend. Organic Light-Emitting Diode (OLED for short) can control the on and off of individual pixels, and the fingerprint recognition technology under the optical screen of mobile phones using OLED screens has entered the commercial era. [0003] Different from OLED, the liquid crystal display (Liquid Crystal Display, LCD) screen generally uses a backlight strip for supplementary light for the screen display of the LCD screen, and cannot control the brightness of a single area, because the backlight module in the LCD display The existence of the reflective film prevents th...
