The target optical signal a1 is reflected by the fingerprint grain F to the fingerprint identification sensor 1, the fingerprint identification sensor 1 receives the target optical signal a1 and converts the target optical signal a1 into a target electrical signal, and the processor stores and identifies the fingerprint information of the fingerprint grain F according to the target electrical signal.
Through set up firstpoint light source 41 in backlight 4 atdisplay screen 10, first light signal a of firstpoint light source 41 transmission jets out behind thedisplay screen 10 with fingerprint line F interact, in order to form target light signal a1, this target light signal a1 is received by fingerprint identification sensor 1 offingerprint sensor module 30 under the screen ofdisplay screen 10 internal integration, so as to realize fingerprint information's discernment,fingerprint sensor module 30 is located the display area ofdisplay screen 10 under the screen, do not occupy the space inelectronic device 100's non-display area, and then can improveelectronic device 100's screen and account for the ratio.
In this embodiment, referring to fig. 6, the fingerprint vein F has a valley F1 and a ridge F2, when the fingerprint vein F touches thetouch substrate 2, the ridge F2 directly contacts thesurface 211 of thetouch substrate 2, and the valley F1 has an air gap with thesurface 211 of thetouch substrate 2. The refractive index n1 (e.g., n1 is 1.55) of the ridge F2 is closer to the refractive index n3 (e.g., n3 is 1.5 for normal glass) of thetouch substrate 2 than the refractive index n2 (e.g., n2 is 1) of air, and thus the intensity of the reflected light of the first optical signal a at thesurface 211 of thetouch substrate 2 is greater than the intensity of the reflected light at the surface of the ridge F2. Therefore, in the fingerprint image acquired by the fingerprint recognition sensor 1, the brightness of the image area corresponding to the valley F1 is strong, and the brightness of the image area corresponding to the ridge F2 is weak. Of course, in other embodiments, the fingerprint pattern F may be located on thetouch substrate 2 and spaced apart from thetouch substrate 2, and the fingerprint image may be obtained by using the difference of the reflection intensity of the light by the valleys F1 and the ridges F2 of the fingerprint pattern F.
In this embodiment, the first optical signal a may be infrared light to reduce interference with the display image of thedisplay screen 10. The second optical signal b may be visible light. In other embodiments, the first optical signal a may also be one or a combination of near infrared light, ultraviolet light, near ultraviolet light, visible light, and the like.
Thus, thedisplay screen 10 integrates touch, display and fingerprint recognition functions at the same time.
