The present application will be described in further detail with reference to the following drawings and examples. It is to be noted that the following examples are only illustrative of the present application, and do not limit the scope of the present application. Likewise, the following examples are only some examples and not all examples of the present application, and all other examples obtained by a person of ordinary skill in the art without any inventive work are within the scope of the present application.

Reference herein to "an embodiment" means that a particular feature, structure, or characteristic described in connection with the embodiment can be included in at least one embodiment of the application. The appearances of the phrase in various places in the specification are not necessarily all referring to the same embodiment, nor are separate or alternative embodiments mutually exclusive of other embodiments. It is explicitly and implicitly understood by one skilled in the art that the embodiments described herein can be combined with other embodiments.

As used herein, an "electronic device" (or simply "terminal") includes, but is not limited to, an apparatus that is configured to receive/transmit communication signals via a wireline connection, such as via a Public Switched Telephone Network (PSTN), a Digital Subscriber Line (DSL), a digital cable, a direct cable connection, and/or another data connection/network, and/or via a wireless interface (e.g., for a cellular network, a Wireless Local Area Network (WLAN), a digital television network such as a DVB-H network, a satellite network, an AM-FM broadcast transmitter, and/or another communication terminal). A communication terminal arranged to communicate over a wireless interface may be referred to as a "wireless communication terminal", "wireless terminal" or "mobile terminal". Examples of mobile terminals include, but are not limited to, satellite or cellular telephones; a Personal Communications System (PCS) terminal that may combine a cellular radiotelephone with data processing, facsimile and data communications capabilities; PDAs that may include radiotelephones, pagers, internet/intranet access, Web browsers, notepads, calendars, and/or Global Positioning System (GPS) receivers; and conventional laptop and/or palmtop receivers or other electronic devices that include a radiotelephone transceiver. A cellular phone is an electronic device equipped with a cellular communication module.

It should be noted that the electronic device in the embodiment of the present application is mainly directed to an electronic device having an identification structure, and in particular, the unlocking and waking functions of the electronic device can be quickly performed by using a fingerprint identification structure. The recognition structure can generally utilize a sensing device such as an electronic device screen lower camera to acquire images so as to achieve the purpose of recognition. It can be understood that the electronic device in the embodiment of the present application may be a tablet computer, a mobile phone, a camera, a personal computer, a notebook computer, an in-vehicle device, a wearable device, or other intelligent devices with an underscreen identification structure.

Referring to fig. 1 and fig. 2, fig. 1 is a schematic view of a display screen 201 of an electronic device 200 in an embodiment related to the present application, fig. 2 is a schematic view of a stacked structure of the electronic device 200 in an embodiment related to the present application, that is, fig. 2 is a schematic view of a cross-sectional structure of the electronic device in fig. 1 along a direction a-a. For an electronic device with an underscreen fingerprint identification structure, the display 201 will typically have an identified region 2011 and a non-identified region 2012. Here, the identification area 2011 is generally set to correspond to the sensing device 202 that can perform identification.

Further, the display surface of the display screen 201 is generally attached to the inner side surface of the glass cover plate 203 of the electronic device, and a window is opened on one side of the non-display surface of the display screen 201, where the window opening position generally corresponds to the position of the identification area 2011, so as to place the sensing device 202 for identification.

However, in the study of the applicant, it was found that, in the above-mentioned display screen structure 201, due to the window, the sensing device 202 is exposed when viewed from the non-display surface of the display screen 201, and a side portion of the non-display surface of the display screen 201 is exposed. In the display process of the display screen 201, the exposed part and the non-exposed part on the non-display surface side of the display screen 201 are different in reflection condition of the light with the different refractive indexes, so that different photoelectric effects are caused on the semiconductor active layer inside the display screen 201, and therefore the phenomenon of uneven display exists in the identification area 2011 and the non-identification area 2012 of the display screen 201, and the use experience of a user is influenced.

For solving the above problem, the idea of this embodiment is that if the semiconductor active layer inside the display screen generates the photoelectric effect of the same degree, the recognition area and the non-recognition area of the display screen do not have the phenomenon of uneven display, so as to improve the user experience.

Based on this, the embodiment of the application provides a display module assembly, display screen subassembly and electronic equipment to solve above-mentioned technical problem. Specifically, please refer to fig. 3 and 4, in which fig. 3 is a schematic structural diagram of an electronic device 100 according to some embodiments of the present application, and fig. 4 is a schematic structural diagram of the electronic device 100 according to some embodiments of the present application. It should be noted that the electronic device in the present application may include a mobile phone, a tablet computer, a notebook computer, a wearable device, and other devices. The electronic device 100 may generally include the following structure: a display screen assembly 10 and a housing 20; the display panel assembly 10 may generally include a display module 11 and a display panel cover 12.

Specifically, the display module 11 is attached to the inner surface of the display cover 12. The shell 20 is connected with the display screen cover plate 12 of the display screen assembly 10 and encloses to form an accommodating space 101, and the display module 11 of the display screen assembly 10 is arranged in the accommodating space 101.

Further, the housing 20 may generally include a rear case 21 and a middle frame 22, wherein the middle frame 22 is disposed between the display module 11 and the rear case 21 and connects the display module 11 and the rear case 21 to form an integral structural frame of the electronic device 100. In the application of the structure of the electronic device 100, the middle frame 22 is generally used to carry or fix internal components of the electronic device 100, such as a main board, a battery, a camera, or a sensing device. The rear shell 21, the middle frame 22 and the display screen cover plate 12 are enclosed to form an accommodating space 101.

The display module 11 may generally include a display surface and a non-display surface (not shown), the display surface and the non-display surface are disposed opposite to each other, the display surface of the display module 11 is attached to the inner surface of the display cover 12, and the non-display surface of the display module 11 is close to the housing 20. Specifically, the display surface of the display module 11 is located outside the electronic device 100 for displaying and corresponding human-computer interaction, and the non-display surface is located inside the electronic device 100 for connecting with other structures of the electronic device 100.

Furthermore, the display module 11 is provided with an identification area 111 for acquiring identification information to perform identification operation, so that the functions of unlocking and waking up the electronic device 100 can be conveniently performed. It can be understood that the display module 11 can be a display screen for displaying a screen, such as a Light Emitting Diode (LED) display screen, an Organic Light-Emitting Diode (OLED) display screen, and the display screen cover plate 12 can be made of glass.

Specifically, the identification information acquired by the identification region 111 may be biometric information, and may be, for example, fingerprint, palm print, iris, voice print, or facial feature information. Wherein, the fingerprint refers to lines formed by concave-convex skin on the finger abdomen at the tail end of the human finger; the palm print refers to a line on the whole palm; the iris is a part of the eye for automatically adjusting the size of the pupil; the voiceprint refers to a sound wave frequency spectrum which carries speech information and is displayed by an electro-acoustic instrument; facial features refer to features of the human face, including facial form, arrangement and appearance of five sense organs, and the like. The biometric information is unique to a user and, therefore, can be used to identify a unique user. In the embodiment of the present application, the identification information acquired by the identification area 111 may be exemplified by the acquired fingerprint information.

In order to implement the identification function of the electronic device 100, the electronic device 100 provided in the embodiment of the present application may further include a sensing device 30, where the sensing device 30 is fixedly disposed on the housing 20. Specifically, the sensing device 30 may be fixedly connected to the rear shell 21 of the casing 20, may be fixedly connected to the middle frame 22 of the casing 20, and may also be fixedly connected to the rear shell 21 and the middle frame 22 of the casing 20, which is not specifically limited in this embodiment of the present invention.

Further, the sensing device 30 is disposed corresponding to the identification area 111 of the display module 11, and the sensing surface of the sensing device 30 faces the display cover 12. Specifically, the sensing device 30 is disposed on a side of the non-display surface of the display module 11, and a projection of the sensing surface of the sensing device 30 in a direction substantially perpendicular to the display module 11 corresponds to the identification area 111, that is, a projection area of the sensing surface of the sensing device 30 projected on the display module 11 covers the identification area 111.

It will be appreciated that the sensing device 30 is a device that can convert biometric information into an electronic signal. For example, the sensing Device 30 may be a camera equipped with one or more sensors of a CCD (Charge-coupled Device), a CMOS (Complementary Metal Oxide Semiconductor), and a CIS (CMOS Image Sensor), and may convert an optical Image into an electronic signal.

Referring to fig. 5 and fig. 6, fig. 5 is a schematic top view structure of a display module 11 according to some embodiments of the present disclosure, and fig. 6 is a schematic cross-sectional structure of the display module 11 along the direction B-B in fig. 5 according to some embodiments of the present disclosure, where the display module 11 may substantially include an auxiliary layer 112, a substrate 113, a shielding layer 114, and a display layer 115, which are sequentially stacked. The display layer 115 includes an identification area 111, and here, the identification area 111 is a fingerprint identification area as an example. The substrate 113 includes a first portion 1131 and a second portion 1132, the first portion 1131 corresponds to a stacked structure including the sensing device 30 under the substrate 113, and the second portion 1132 corresponds to a stacked structure including the auxiliary layer 112 under the substrate 113. Here, the sensing device 30 is exemplified by a light-sensing fingerprint sensor, which can be used to realize fingerprint recognition.

Specifically, the first portion 1131 of the substrate 113 corresponds to a stacked structure including the sensing device 30, the substrate 113 located above the sensing device 30, the blocking layer 114 located above the substrate 113, and the display layer 115 located above the blocking layer 114; the second portion 1132 corresponds to a stacked structure including the auxiliary layer 112, the substrate 113 over the auxiliary layer 112, the blocking layer 114 over the substrate 113, and the display layer 115 over the blocking layer 114. Further, as seen from below in the orientation shown in fig. 6, the second portion 1132 of the substrate 113 is in contact with the auxiliary layer 112, and the first portion 1131 is exposed, i.e., in contact with air, i.e., the first portion 1131 is disposed corresponding to the identification area 111 of the display layer 115.

It should be noted that all the directional indicators (such as upper, lower, left, right, front and rear … …) in the embodiment of the present application are only used to explain the relative position relationship between the components, the motion situation, etc. in a specific posture (as shown in the drawings), and if the specific posture is changed, the directional indicator is changed accordingly.

Further, the auxiliary layer 112 is disposed corresponding to the second portion 1132 of the substrate 113, that is, an avoiding region is disposed on the auxiliary layer 112 to avoid the first portion 1131 of the substrate 113 from being avoided, so as to prevent light from entering the light-sensitive fingerprint sensor and being unable to be identified. Obviously, the auxiliary layer 112 is generally opaque. The shielding layer 114 includes a plurality of shielding units (1141, 1142, 1143 …) distributed in an array, and the display layer 115 includes a plurality of pixel units (1151, 1152, 1153 …) distributed in an array. The shielding units of the shielding layer 114 are disposed corresponding to the pixel units of the display layer 115, that is, the projection of the shielding unit 1141 projected on the display layer 115 substantially covers the pixel unit 1151, the projection of the shielding unit 1142 projected on the display layer 115 substantially covers the pixel unit 1152, the projection of the shielding unit 1143 projected on the display layer 115 substantially covers the pixel unit 1153, and so on, so as to form a structure in which the shielding units and the pixel units are disposed in one-to-one correspondence. The shielding layer 114 is generally opaque, and light can be reflected on the shielding layer 114, so that the reflected light inside the display module 100 can uniformly irradiate the pixel units of the display layer 115, and further the entire display effect of the display module 100 is consistent.

It is understood that the plurality of shielding units (1141, 1142, 1143 …) and the plurality of pixel units (1151, 1152, 1153 …) have corresponding gaps therebetween, so that light can pass through and irradiate the light-sensitive fingerprint identification sensor for identification. Furthermore, the gaps may be filled with a light-permeable material to enhance the stability of the overall structure of the display module 11.

Specifically, referring to fig. 7, fig. 7 is a partial structural schematic diagram of a pixel unit in some embodiments of the present application, and the pixel unit of the display layer 115 generally includes a light emitting element 1155 and a thin film transistor 1156, wherein the thin film transistor 1156 is electrically connected to the light emitting element 1155 to drive the light emitting element 1155 to emit light. Further, the light emitting element 1155 is provided away from the shielding layer 114, and the thin film transistor 1156 is provided close to the shielding layer 114.

Specifically, the light-emitting element 1155 generally includes an anode layer 11551, a light-emitting layer 11552, and a cathode layer 11553, which are stacked in this order, wherein the anode layer 11551 is close to the substrate 113, and the cathode layer 11553 is far from the substrate 113. The thin film transistor 1156 generally includes a source electrode 11561, a drain electrode 11562, a gate electrode 11563 and an active layer 11564, wherein the source electrode 11561 is generally electrically connected to a pixel electrode corresponding to the light emitting element 1155, so as to drive the light emitting element 1155 to emit light.

It is understood that in the display module structure, each pixel unit has a Thin Film Transistor (TFT), a gate of the TFT is connected to a scan line, a drain of the TFT is connected to a data line, and a source of the TFT is connected to a pixel electrode. When enough voltage is applied to the scanning line, all the thin film transistors on the scanning line are turned on, and at the moment, the display signal voltage on the data line is written into the pixel to control the transmittance of different liquid crystals so as to achieve the effect of controlling the color. It should be further understood that the specific connection mode and operation principle of the light emitting element and the thin film transistor are within the understanding range of those skilled in the art, and therefore, the embodiments of the present application are not described in detail.

Further, since the sensing device 30 does not have the auxiliary layer 112 at a corresponding position, so that the stacking structures of the first portion 1131 and the second portion 1132 of the substrate 113 are different, in use, light emitted by the luminescent material inside the display module 11 will be reflected and refracted at the interface between the first portion 1131 of the substrate 113 and the auxiliary layer 112 and the interface between the second portion 1132 and the air, and the reflected and folded light will irradiate the active layer 11564 of the tft 1156. Typically, the active layer 11564 is made of a semiconductor material, such as semiconductor polysilicon. Under the irradiation of light, the active layer generates a photoelectric effect to generate a photon-generated carrier, which causes the change of the carrier concentration in the channel of the thin film transistor, so that a certain amount of induced charges are accumulated on the back of the display module, and a reverse electric field is formed to act on the channel carrier.

Specifically, when the first portion 1131 and the second portion 1132 of the substrate 113 have different reflection or refraction conditions, the concentration of carriers in the channel is also different accordingly, so that the amount of induced charges accumulated on the back surface of the display module is different, and the display effects of the identification region 111 and the non-identification region of the display layer 115 are inconsistent.

Based on this, the embodiment of the present application provides the shielding layer 114 between the substrate 113 and the display layer 115, wherein the light emitting element 1155 of the display layer 115 is disposed away from the shielding unit of the shielding layer 114, and the active layer 11564 of the thin film transistor 1156 is disposed close to the shielding unit of the shielding layer 114, so that the active layer 11564 can receive uniform reflected light. Specifically, when the shielding layer 114 is disposed between the substrate 113 and the display layer 115, light emitted by the light emitting element 1155 can be almost totally reflected on the shielding layer 114, so that the reflected light received by the active layer 11564 is uniform, the concentration of carriers in the channel is substantially the same, and the amount of induced charges accumulated on the back surface of the display module is substantially the same, so that the identification region 111 and the non-identification region of the display layer 115 have a uniform display effect.

It should be noted that the terms "first", "second" and "third" in the present application are used for descriptive purposes only and are not to be construed as indicating or implying relative importance or implying any number of indicated technical features. Thus, a feature defined as "first," "second," or "third" may explicitly or implicitly include at least one of the feature. In the description of the present application, "plurality" means at least two, e.g., two, three, etc., unless explicitly specifically limited otherwise.

In further research, the applicant finds that if induced charges accumulated on the back surface of the display module are conducted away, a reverse electric field is not formed to act on channel carriers to influence the display effect. In view of this, in some embodiments of the present disclosure, the shielding layer 114 is made of a metal material for guiding away the induced charges accumulated on the back surface of the display module. Specifically, the shielding layer 114 is grounded to form a shielding layer, so that the induced charges are not accumulated on the surface of the display module 11 away from the display layer 115, and the display effect of the display module 11 is uniform.

Further, the shielding layer 114 may be made of a conductive metal material such as molybdenum (Mo), copper (Cu), etc., and is made by a patterning process, i.e., the shielding layer 144 is patterned to form shielding units distributed in an array. For example, the shielding units may be formed in an array by patterning processes such as Physical Vapor Deposition (PVD), Atomic Layer Deposition (ALD), Pulsed Laser Deposition (PLD), or Sputter Deposition (Sputter Deposition).

In some embodiments of the present application, the display module 11 further includes an insulating layer 116, and the insulating layer 116 is disposed between the shielding layer 114 and the display layer 115, so that the shielding layer 114 and the display layer 115 are insulated from each other, and moisture and the like can be blocked from entering the display module.

Further, the insulating layer 116 is generally made of transparent silicide, which not only can perform an insulating function, but also can prevent light from entering and planarize the display module, so that the overall structure of the display module is more stable. For example, the insulating layer 116 may be made of one or more of silicide such as SiNx and SiOx. In order to achieve the full-surface insulation effect, the insulating layer 116 may be made by Chemical Vapor Deposition (CVD). Of course, in other embodiments, the insulating layer 116 may also be made of an insulating material such as polycycloolefin polymer.

In some embodiments of the present application, please refer to fig. 8 in combination, where fig. 8 is a schematic structural diagram of the auxiliary layer 112 in some embodiments of the present application, in which the auxiliary layer 112 generally includes a buffer 1121 and a ground element 1122. Specifically, the buffer 1121 is disposed close to the substrate 113, and the ground 1122 is disposed away from the substrate 113.

Further, the auxiliary layer 112 is adhered to the substrate 113 by a glue 118 to fixedly connect the auxiliary layer 112 and the substrate 113. Further, the buffer 1121 is bonded to the substrate 113 through the adhesive 118.

Specifically, the buffer 1121 may be made of a material having a certain elasticity, such as foam, rubber, or the like; the ground 1122 may be made of a conductive material such as Cu; the gel 118 may be made of one or more materials such as double-sided Adhesive, OCA (Optical Clear Adhesive, OCA), Optical Clear Resin (OCR), and Pressure Sensitive Adhesive (PSA).

It can be understood that the buffer 1121 is made of an elastic material to provide a good buffering protection effect. The grounding member 1122 is made of a conductive material, so that induced charges accumulated on a surface of the display module 11 corresponding to the grounding member 1122 can be conducted away, thereby preventing a reverse electric field from being generated.

Further, the substrate 113 is generally made of a transparent material such as PET (polyethylene terephthalate), PI (Polyimide), etc., and has a light weight and does not greatly affect the overall weight of the device. However, the applicant has found that when the ground element 1122 conducts away the induced charges accumulated on the side of the display module 11 corresponding to the ground element 1122, the induced charges accumulated on the substrate 113 not corresponding to the ground element 1122 will cause inconsistent display effect of the display module if not conducted away. Based on this, the substrate 113 provided in the embodiment of the present application may be made of a transparent conductive material. For example, sulfur ions may be added to PET to form a conductive material having conductivity.

The display module assembly that this application embodiment provided shelters from the layer through setting up for the inside photoelectric effect that produces the same degree of display module assembly that the identification area on display layer and non-identification area correspond, and then make the whole face display effect of display module assembly even unanimous, promote user's use and experience.

In other embodiments of the present application, please refer to fig. 9, where fig. 9 is a schematic structural diagram of the auxiliary layer 112 in other embodiments of the present application, wherein the auxiliary layer 112 further includes a heat dissipation element 1123, and the heat dissipation element 1123 is disposed between the buffer element 1121 and the ground element 1122. The heat sink 1123 is generally made of heat sink materials such as graphite, aluminum sheet, copper sheet, etc., which have high heat conduction efficiency.

In other embodiments of the present application, please refer to fig. 10, fig. 10 is a schematic structural diagram of the display module 11 in other embodiments of the present application, in which the display module 11 further includes a base 117, and the base 117 is disposed between the substrate 113 and the shielding layer 114 for isolating moisture and oxygen and planarizing the display module.

Further, the substrate 117 is made of a transparent material, for example, the substrate 117 may be made of a transparent material such as PET, PI, etc., which has a light weight and does not have a great influence on the overall weight of the machine. Of course, in other embodiments, the substrate 117 may also be a composite layer structure, for example, the substrate 117 may be made of PI, the PI may be made of two layers, each layer has a thickness of approximately 8-10 μm, and an inorganic thin film may be disposed between the two PI films to prevent moisture and the like from entering. The material of the inorganic thin film includes, but is not limited to, one or a combination of two or more of Al2O3, TiO2, SiNx, SiCNx, SiOx, and the like, and an inorganic functional material for increasing a water blocking function.

Referring to fig. 3 and 4, the present embodiment further provides a display panel assembly 10, where the display panel assembly 10 may generally include a display module 11 and a display panel cover 12, and a display surface of the display module 11 is attached to an inner surface of the display panel cover 12. The display module 11 may be the display module 11 described in the foregoing embodiments.

Of course, in other embodiments, the display panel assembly 10 may further include a touch panel (not shown) attached between the display module 11 and the display cover 12.

Specifically, the touch panel can be attached between the display module 11 and the display panel cover 12 through the OCA optical adhesive. The display module 11 may be the display module 11 described in the foregoing embodiments, and will not be described in detail here.
