Definitions
- the use of a full-screen solution for electronic devices can enable users to obtain a larger display interface.
- users are increasingly pursuing a more technological sense of under-screen fingerprint recognition, that is, using fingerprint recognition.
- the module is arranged below the display screen, thereby increasing the screen ratio of the electronic device.
- first, second and the like in the description and claims of the present application are used to distinguish similar objects, and are not used to describe a specific order or sequence. It is to be understood that the data so used are interchangeable under appropriate circumstances so that the embodiments of the present application can be practiced in sequences other than those illustrated or described herein, and distinguish between “first”, “second”, etc.
- the objects are usually of one type, and the number of objects is not limited.
- the first object may be one or more than one.
- “and/or” in the description and claims indicates at least one of the connected objects, and the character “/" generally indicates that the associated objects are in an "or” relationship.
- an embodiment of the present application discloses a display screen, the display screen includes a display module 100 , a backlight module 200 , a fingerprint identification module 300 and a light-transmitting cover plate 500 .

- the fingerprint recognition light source 310 and the backlight source 230 are located on the same side of the light bar 220 .
- the fingerprint recognition light source 310 is required to work, only the fingerprint recognition light source 310 can be driven, and when only the backlight source 230 is required to work, only the backlight source 230 can be driven.
- Disposing the fingerprint identification light source 310 and the backlight source 230 on the same side of the light bar 220 can facilitate the wiring layout and facilitate the rational planning of the devices in the display screen.
- the backlight source 230 is generally disposed on the side of the light bar 220 facing the display module 100. Therefore, the fingerprint recognition light source 310 is also facing the display module 100, so that more light can be irradiated to the display module 100, thereby improving fingerprints. identification efficiency.
- this embodiment of the present application does not limit this. Disposing the light guide assembly 240 in the backlight module 200 can make the light emitted after the backlight source 230 or the fingerprint recognition light source 310 is driven to pass through the display module 100 more uniformly, thereby preventing the display module 100 from appearing with different brightness and darkness. phenomenon, thereby improving the display effect of the display screen and the efficiency of fingerprint recognition.
- the display screen further includes a first circuit board 400, the first circuit board 400 is electrically connected to the display module 100, the backlight source 230 is electrically connected to the first circuit board 400 through the first electrical connection line 410, and the fingerprint recognition
- the light source 310 is electrically connected to the first circuit board 400 through the second electrical connection line 420 .
- the first circuit board 400 is further provided with solder joints 401 , and the first electrical connection line 410 and the second electrical connection line 420 can be soldered with the solder joints 401 on the first circuit board 400 to realize the backlight source 230 and the fingerprint recognition light source 310 respectively. Electrical connection to the first circuit board 400 .
- the light guide assembly 240 includes a reflective sheet 241 and a light guide plate 242.
- the reflective sheet 241 and the light guide plate 242 can evenly cover the display module 100 with the light emitted by the backlight source 230 or the fingerprint identification light source 310, In order to avoid the phenomenon of uneven brightness and darkness on the display.
- the filter layer 320 and the image sensor layer 330 are disposed between the reflective sheet 241 and the light guide plate 242.
- the reflective sheet 241 can fully play a reflective role without affecting the light reflected by the finger entering the image sensor layer 330
- the light guide plate 242 is located above the filter layer 320 and the image sensor layer 330 , so that the light reflected by the finger can enter the image sensor layer 330 more uniformly.
