Through fingerprint module 20 is embedded in the non-display area 12 of display screen 10, fingerprint module 20 can follow display area 11 receives fingerprint detection signal, makes display area 11 of display screen 10 need not set up special signal conduction structure, and has satisfied the requirement of the normal received signal of fingerprint module 20 has guaranteed the display effect of display screen 10.

In this embodiment, the display screen 10 includes a front surface 13 facing a user and a back surface 14 disposed opposite to the front surface 13, and the fingerprint module 20 is located between the front surface 13 and the back surface 14. The non-display region 12 is disposed around the display region 11. The display screen 10 is a full-screen. The width of the non-display area 12 is narrower to increase the screen occupation ratio of the display area 11. The fingerprint module 20 may be a micro module, so as to conveniently embed the fingerprint module 20 in the non-display area 12. When user's finger contradict in front 13, fingerprint module 20 can pass through display area 11 receives fingerprint detection signal, realizes display area 11 sets up the fingerprint identification region. Through can display area 11 sets up the fingerprint identification region, effectively utilized display area 11's arrangement area, and avoid non-display area 12 arranges the fingerprint identification region, prevents that non-display area 12 area from increasing, has effectively improved the screen area of display screen 10 is compared. It can be understood that, the fingerprint module 20 is embedded in the non-display area 12, and can receive the fingerprint detection signal of the user fingerprint from the display area 11, that is, the fingerprint module 20 can receive the fingerprint detection signal in the direction inclined to the normal direction of the display screen 10, and avoid the fingerprint detection signal to completely pass through the display area 11 of the display screen 10, avoid setting a conduction structure for specially conducting the fingerprint detection signal in the display area 11, prevent the structure of the display area 11 from being damaged, and ensure the display effect of the display area 11 of the display screen 10.

In this embodiment, the display screen 10 includes a first short side 15, a second short side 16, and two long sides 17. The first short side 15 is arranged opposite the second short side 16. The two long sides 17 are connected between the first short side 15 and the second short side 16. The non-display area 12 comprises a first narrow area 151 connecting the first short side 15. The first narrow region 151 may form a "chin" structure of the display screen 10. The fingerprint module 20 is embedded in the first narrow area 151. The display screen 10 may further arrange devices such as driving lines and packaging structures in the first narrow region 151. The non-display area 12 further comprises a second narrow area 161 connecting the second short side 16. The second narrow region 161 may be provided with a speaker outlet, so that after the display screen 10 is applied to an electronic device, the display region 11 of the display screen 10 may cover a speaker, and the speaker may sound through the speaker outlet.

Of course, in other embodiments, the second narrow region 161 may also be provided with a protruding region toward the first narrow region 151, so that the protruding region is utilized to arrange the camera holes, which is convenient for the camera module of the electronic device 200 to shoot through the camera holes. The raised area may be "drop" shaped, or "bang" shaped, or "triangular" shaped.

Referring to fig. 3, fig. 4 and fig. 5, in an embodiment, the display screen 10 includes a display screen cover 101, a liquid crystal panel 102 and a light emitting module 103. The display screen cover plate 101 is provided with a light transmission area 1011 and a non-light transmission area 1012, the non-light transmission area 1012 is overlapped with the non-display area 12, and the light transmission area 1011 is overlapped with the display area 11. The liquid crystal panel 102 is attached to the display cover 101. The fingerprint module 20 is fixed between the light emitting module 103 and the liquid crystal panel 102. The light emitting module 103 may provide backlight to the liquid crystal panel 102. The light emitted from the light emitting module 103 can form a display image through the liquid crystal panel 102 and exit through the light transmissive region 1011.

The display screen cover plate 101 includes a transparent glass and an ink layer attached to the transparent glass. The front surface 13 is disposed on the transparent glass. The ink layer is attached to one surface of the transparent glass, which is far away from the front surface 13. The ink layer forms the non-transmissive region 1012 in the region of the light transmissive glass. The light-transmitting area 1011 is formed by the staggered area of the light-transmitting glass and the ink layer.

The liquid crystal panel 102 may be bonded to the display cover 101 through an optical adhesive. The liquid crystal panel 102 includes a liquid crystal area 1021 and a sealing area 1022 for sealing the liquid crystal area 1021. The liquid crystal region 1021 substantially coincides with the light-transmitting region 1011. The encapsulation region 1022 is covered by the opaque region 1012. The fingerprint module 20 may be engaged with the packaging region 1022, or stacked with the packaging region 1022.

Specifically, the packaging region 1022 may be provided with a groove 1023, and the fingerprint module 20 is embedded in the groove 1023, so as to reduce the arrangement area of the non-light-transmission region 1012, i.e. increase the screen area of the display region 11 of the display screen 10. More specifically, the liquid crystal panel 102 includes a front polarizer, a pixel film, a liquid crystal layer, a TFT matrix film, and a rear polarizer, which are sequentially stacked. The front polarizer is attached to the display screen cover plate 101.

A touch layer can be arranged between the front polarizer and the display screen cover plate 101. Of course, a touch layer may also be integrated in the display screen cover 101, so that the display screen 10 is the touch display screen 10. When a user's finger abuts against the front surface 13 of the display screen cover plate 101, the touch layer can sense a finger pressing area. The liquid crystal panel 102 may form a signal conduction region according to the pressing region, so as to realize that the signal transmission region transmits a fingerprint detection signal detected by a fingerprint of a user, so that the fingerprint module 20 may receive the fingerprint detection signal.

When the fingerprint detection signal is a visible light signal, the liquid crystal panel 102 controls the orientation of the liquid crystal in the signal transmission area, so that the signal transmission area can transmit visible light, and the fingerprint module 20 can receive the fingerprint detection signal conveniently. Of course, in other embodiments, if the fingerprint detection signal is an invisible light signal, a temperature signal, an electromagnetic signal, or the like, the liquid crystal panel 102 may transmit the fingerprint detection signal in a full bright screen state or a full off screen state.

The liquid crystal panel 102 may further determine a bright screen area according to the pressing area sensed by the touch layer. The bright screen area can penetrate through the light of the light emitting module 103, so that the light of the bright screen area can be irradiated to a finger of a user through the display screen cover plate 101, a fingerprint detection signal is formed through the fingerprint of the finger of the user, and fingerprint identification is realized. That is, the liquid crystal panel 102 and the light emitting module 103 are partially lit to form an emission source of an initial fingerprint detection signal.

The light emitting module 103 includes a light emitting portion 1031 and a sealing portion 1032 connected to the light emitting portion 1031. The light emitting portion 1031 substantially overlaps the liquid crystal region 1021 of the liquid crystal panel 102. The light emitting part 1031 may emit light to the liquid crystal region 1021. The packaging part 1032 collides with the fingerprint module 20 to realize that the fingerprint module 20 is embedded in the non-display area 12 of the display screen 10. Because the thickness of the fingerprint module 20 is greater than the liquid crystal panel 102, the fingerprint module 20 can be disposed obliquely relative to the liquid crystal panel 102 or substantially parallel to the liquid crystal panel 102 when abutting against the fingerprint module 20. By utilizing the fingerprint module 20 to be firmly fixed between the liquid crystal panel 102 and the light-emitting module 103, the structural optimization of the display screen assembly 100 is realized, the display effect of the display screen assembly 100 is ensured, and the fingerprint identification requirement is met, so that the display screen assembly 100 is firmly fixed in structure.

In order to make the structure of the display screen assembly 100 more stable, the encapsulation portion 1032 of the light emitting module 103 abuts against the fingerprint module 20. The edge of the light emitting module 103 away from the fingerprint module 20 abuts against the liquid crystal panel 102. The light emitting module 103 has a bottom surface 1033 away from the liquid crystal panel 102 and inclined with respect to the liquid crystal panel 102. Since the bottom surface 1033 is inclined with respect to the liquid crystal panel 102, the increase of the overall thickness of the display screen assembly 100 is avoided, so that the display screen assembly 100 can save the arrangement space, and the display screen assembly 100 is conveniently installed in the electronic device 200.

Specifically, the light emitting module 103 includes a base 1034, a backlight 1035, a light source driving chip 1036, and a backlight light guide 1037. The bottom surface 1033 is disposed on the bottom plate 1034. An edge of the base plate 1034 is provided with a curved extension 1038. The inner side of the curved extension 1038 forms a receiving space, and the backlight 1035 and the light source driving chip 1036 are fixed in the receiving space. The curved extension portion 1038, the backlight 1035, and the light source driving chip 1036 constitute the encapsulating portion 1032. The curved extension 1038 shields the backlight 1035 from light leakage from the backlight 1035. The fingerprint module 20 can be supported against the curved extension 1038. The backlight light guide plate 1037 is attached to the bottom plate 1034 facing the liquid crystal panel 102. The backlight light guide plate 1037 may be tilted with respect to the liquid crystal panel 102 along with the bottom plate 1034. The backlight light guide plate 1037 is provided with a light emitting surface 1039 facing the liquid crystal panel 102. The edge of the backlight light guide plate 1037 extends into the receiving space, so that the backlight light guide plate 1037 can receive the light of the backlight source 1035 and transmit the light to the liquid crystal panel 102. The backlight source 1035 is encapsulated by the curved extension 1038, the fingerprint module 20 can be effectively supported, and the curved extension 1038 can be hidden in the non-light-transmitting area 1012 of the display screen cover plate 101, so that the display screen assembly 100 is optimized in structure, the screen occupation ratio is improved, the display effect is ensured, and the large-area fingerprint identification performance can be realized.

In this embodiment, the light emitting surface 1039 is disposed obliquely with respect to the liquid crystal panel 102. The light emitting surface 1039 at least covers the liquid crystal area 1021 of the liquid crystal panel 102 to ensure that the display area 11 of the display screen 10 can normally display images. That is, there is a gap between the light emitting surface 1039 and the liquid crystal panel 102 near the edge of the fingerprint module 20, and the edge of the light emitting surface 1039 far from the fingerprint module 20 is abutted against the liquid crystal panel 102. If the light emitting surface 1039 is isolated from the liquid crystal panel 102 by air, the brightness transmitted from the light emitting module 103 to the liquid crystal panel 102 is not uniformly distributed. In order to ensure that the brightness of the backlight light received by the liquid crystal panel 102 can be uniformly distributed, an optical filling layer 104 is disposed between the light emitting surface 1039 and the liquid crystal panel 102. The optical filling layer 104 can conduct the light of the light emitting module 103 to the liquid crystal panel 102. The optical filling layer 104 is attached to the liquid crystal panel 102 and the light emitting module 103. The light transmittance of the optical filling layer 104 may gradually increase as the thickness of the optical filling layer 104 increases. That is, the light transmittance of the optical filling layer 104 near the fingerprint module 20 is greater than the light transmittance of the optical filling layer 104 far from the fingerprint module 20. The light of the light emitting module 103 is transmitted to the liquid crystal panel 102 after passing through the optical filling layer 104, so that the brightness of the light received by the liquid crystal panel 102 can be distributed in a balanced manner, that is, the brightness of the image displayed in the display area 11 is distributed in a balanced manner. Of course, in other embodiments, the light emitting module 103 and the liquid crystal panel 102 may be isolated from each other by air, and the light emitting brightness of the light emitting module 103 may change along with the position close to or far from the fingerprint module 20, that is, the light emitting brightness of the light emitting module 103 gradually decreases from the position close to the position far from the fingerprint module 20, so that the brightness of the image displayed in the display area 11 may be evenly distributed. Since the optical filling layer 104 completely fills the gap between the light emitting module 103 and the liquid crystal panel 102, the optical filling layer 104 can support the liquid crystal panel 102 and the light emitting module 103, so that the display screen assembly 100 is stable. Of course, in other embodiments, the optical filling layer 104 may be disposed between the light emitting module 103 and the liquid crystal panel 102, the light transmittance of the optical filling layer 104 gradually decreases from close to far from the fingerprint module 20, and the light emitting brightness of the light emitting module 103 gradually decreases from close to far from the fingerprint module 20.

Referring to fig. 6, in another embodiment, substantially the same as the embodiment shown in fig. 5, except that the light-emitting module 103 includes a bottom plate 1034, a filling plate 105 and a backlight light guide plate 1037 stacked in sequence, the bottom surface 1033 is disposed on the bottom plate 1034, the light-emitting surface 1039 is disposed on the backlight light guide plate 1037, and the fingerprint module 20 is fixed at a position where the bottom plate 1034 is opposite to the non-display region 12. The light emitting surface 1039 is attached to the liquid crystal panel 102, that is, the backlight light guide plate 1037 is attached to the liquid crystal panel 102. The bottom plate 1034 is inclined with respect to the backlight light guide plate 1037. The edge of the backlight light guide plate 1037 close to the fingerprint module 20 extends into the curved extension 1038 and abuts against the backlight source 1035, so that the backlight light guide plate 1037 receives the light of the backlight source 1035. The backlight light guide plate 1037 may be abutted against the fingerprint module 20 through the curved extension 1038 to reduce the occupation ratio of the non-display area 12 of the display screen 10 and increase the occupation ratio of the display area 11. The infill panel 105 is close to the thickness of fingerprint module 20 department is greater than keeping away from the thickness of fingerprint module 20 department. The filling board 105 effectively supports the backlight light guide plate 1037, so that the light emitting module 103 has a stable structure. Because the thicknesses of the backlight light guide plates 1037 are uniform and uniform, the brightness of the light received by the liquid crystal panel 102 is uniformly distributed, and the packaging part 1032 of the light emitting module 103 can effectively support the fingerprint module 20, thereby ensuring the display performance of the display screen assembly 100 and meeting the requirement of fingerprint identification under the screen.

Referring to fig. 7, in another embodiment, substantially the same as the embodiment shown in fig. 6, except that a space 1040 exists between the backlight light guide plate 1037 and the fingerprint module 20. The fingerprint module 20 can send or/and receive fingerprint detection signals through the gap 1040. It can be understood that the backlight light guide plate 1037 includes a reflective film, a light guide film, a brightness enhancement film and a light uniformizing film, which are sequentially attached. The light transmittance of the reflecting film, the light guide film, the brightness enhancement film and the light homogenizing film is 1%, 60%, 1.4% and 3.8% in sequence. When the fingerprint detection signal received by the fingerprint module 20 is an optical signal, it is obvious that the backlight light guide plate 1037 has a higher blocking ratio for the optical signal. Through backlight light guide plate 1037 with set up between the fingerprint module 20 interval 1040, fingerprint module 20 passes through interval 1040 sends or/and receives fingerprint detection signal, in order to guarantee fingerprint module 20 can effectively receive or/and send fingerprint detection signal, guarantees fingerprint identification's validity. Of course, it can be understood that, when the fingerprint detection signal is other non-optical signals, the backlight light guide plate 1037 and the fingerprint module 20 are disposed with the gap 1040 therebetween, and the gap 1040 can also ensure effective conduction of the fingerprint detection signal, so as to reduce the blockage of the backlight light guide plate 1037 to the fingerprint detection signal, and meet the validity of fingerprint identification.

Referring to fig. 8, in another embodiment, substantially the same as the embodiment shown in fig. 4, except that the light emitting module 103 is disposed in parallel with the liquid crystal panel 102. An optical filling layer 104 is disposed between the light emitting module 103 and the liquid crystal panel 102. The two opposite surfaces of the optical filling layer 104 are arranged in parallel, and the optical filling layer 104 transmits the light of the light emitting module 103 to the liquid crystal panel 102. Of course, in other embodiments, the light emitting surface 1039 of the light emitting module 103 may be isolated from the liquid crystal plane by air, and the light emitting surface 1039 of the light emitting module 103 is disposed in parallel with the liquid crystal panel 102.

Referring to fig. 9, in another embodiment, substantially the same as the embodiment shown in fig. 4, except that the light emitted from the light emitting module 103 can form a display image through the display cover 101. The light emitting module 103 is provided with a plurality of pixel light sources 103c arrayed in the display area 11, and light rays of the pixel light sources 103c can form a display image to be emitted through the light transmitting area 1011. Each pixel light source 103c may be a micro LED lamp bead. Namely, the display screen 10 is a Micro-LED display screen 10. The light emitting module 103 includes a light emitting portion 103a and a driving portion 103 b. The light emitting portion 103a substantially coincides with the light transmitting area 1011 of the display panel cover 101. The plurality of pixel light sources 103c are arrayed in the light emitting portion 103 a. The driving portion 103b is configured to drive the plurality of pixel light sources 103c to emit light. The non-light-transmitting region 1012 of the display panel cover 101 covers the driving portion 103 b. The fingerprint module 20 is fixed between the driving portion 103b and the display screen cover 101. The light emitting module 103 may be disposed to be inclined with respect to the display cover 101, or may be disposed to be parallel to the display cover 101.

Further, referring to fig. 10, the fingerprint module 20 includes a detection signal source 21 and a signal sensing chip 22 fixed relative to the detection signal source 21, the detection signal source 21 can transmit an initial detection signal to the display area 11, and the signal sensing chip 22 can receive a fingerprint detection signal from the display area 11.

In this embodiment, the detection signal source 21 may emit an initial detection signal toward the light-transmitting area 1011 of the display panel cover 101. When the finger of the user contacts the light-transmitting area 1011, the initial detection signal is conducted to the finger of the user, and the initial detection signal has different reflectivities in the ridge area and the valley area of the fingerprint of the user, so that the initial detection signal forms a fingerprint detection signal after being reflected by the surface of the fingerprint of the user. The fingerprint detection signal has a ridge signal reflected from a ridge area of the fingerprint and a valley signal reflected from a valley area, and a rate of change of the ridge signal is different from a rate of change of the valley signal. After the signal sensing chip 22 senses the fingerprint detection signal, a fingerprint image can be formed by processing according to the change rate of the ridge signal and the change rate of the valley signal.

It is understood that, in other embodiments, the detection signal source 21 emits an initial detection signal toward the transparent area 1011 of the display screen cover 101, the user's finger abuts against the transparent area 1011, the initial detection signal enters the inside of the user's finger and is conducted to the area where the user's finger contacts the display screen cover 101, and the initial detection signal has different emittance in the ridge area and the valley area of the user's finger fingerprint, so that the initial detection signal forms a fingerprint detection signal after being emitted through the surface of the user's fingerprint. The fingerprint detection signal has a ridge signal emerging from a ridge region of the fingerprint and a valley signal emerging from a valley region, and a rate of change of the ridge signal is different from a rate of change of the valley signal. After the signal sensing chip 22 senses the fingerprint detection signal, a fingerprint image can be formed by processing according to the change rate of the ridge signal and the change rate of the valley signal.

Specifically, the orientation of the detection signal source 21 and the orientation of the signal sensing chip 22 may form an included angle. The detection signal source 21 and the signal sensing chip 22 may be respectively arranged on two supporting surfaces of the fingerprint module 20, which form an included angle therebetween.

More specifically, the fingerprint module 20 further includes a package 23, and the package 23 has a top surface 231 facing the display cover 101. The package 23 also has a bottom surface 1033 disposed opposite the top surface 231. The package 23 also has a first side 232 connected to the top surface 231 and the bottom surface 1033 and a second side 233 opposite the first side 232.
