[0010] In some embodiments, a black matrix layer is arranged on the side of the protective cover plate facing the display film layer, and a projection of the light inlet surface on the cover plate body falls within the range of the black matrix layer.

[0011] In some embodiments, the area of the black matrix layer directly opposite the light inlet area comprises at least one of infrared ink and uniform light ink.

[0012] wherein the infrared ink is used to filter infrared rays in ambient light, and the uniform light ink is used to diffuse light.

[0013] According to a second aspect of the present disclosure, an electronic device is provided, comprising a frame structure and a light sensing element, and a display module as described in the first aspect.

[0014] In some embodiments, the display film layer and the middle frame structure enclose a light inlet channel, the light inlet channel comprising a first channel, a second channel and a third channel connected in sequence, the first channel and the third channel being parallel to the extension direction of the second channel.

[0015] In some embodiments, in the extension direction of the second channel, the two ends of the second channel are respectively provided with a first reflecting surface and a second reflecting surface, the first reflecting surface and the second reflecting surface being formed by part of the middle frame structure, the first reflecting surface being configured to reflect ambient light to form first reflected light, and the second reflecting surface being configured to reflect the first reflected light to form second reflected light, the second reflected light being configured to enter the photosensitive element.

[0016] In some embodiments, the first reflecting surface and / or the second reflecting surface is provided with a reflection enhancement layer.

[0017] In some embodiments, in the extension direction of the second channel, the side of the sealing part away from the display film layer is attached to the middle frame structure to form a seal.

[0018] The assembly gap between the middle frame structure and the protective cover plate is communicated with the sealing part.

[0019] In some embodiments, the sealing part at least fills the first channel.

[0020] In some embodiments, the sealing part comprises:

[0021] a first light guide structure arranged in the first channel;

[0022] a second light guide structure arranged in the second channel, the extension direction of the second light guide structure being perpendicular to the extension direction of the first light guide structure;

[0023] In some embodiments, the two ends of the second light guide structure are respectively attached to the first reflecting surface and the second reflecting surface, and the area of the second light guide structure opposite to the third channel forms the light exit surface.

[0024] In some embodiments, in the extension direction of the first channel, the side of the second light guide structure away from the first light guide structure is flush with the second channel.

[0025] The technical solutions provided by the embodiments of this disclosure may include the following beneficial effects: using a light-transmitting material to make the sealing part can not only provide sealing and waterproofing for the protective cover and display film layer, but also allow light to pass through and guide ambient light to illuminate the photosensitive element. There is no need to set up a glue groove, which helps to reduce the black border size of the display module, thereby increasing the screen ratio of the electronic device. It also avoids the situation where the adhesive in the glue groove contaminates the sealing part during assembly, which helps to improve the product yield.

[0026] It should be understood that the above general description and the following detailed description are exemplary and explanatory only, and are not intended to limit this disclosure. Attached Figure Description

[0033] Figure 6 This is illustrated according to yet another exemplary embodiment. Figure 1 Cross-sectional view along the AA direction. Detailed Implementation

[0034] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numerals in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this disclosure. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this disclosure as detailed in the appended claims.

[0035] In the related art, an electronic device is usually provided with a screen decoration piece to achieve waterproof of the screen. For example, a glue groove can be provided on the side of the screen decoration piece facing the screen cover plate, and the screen cover plate can be sealingly connected with the screen decoration piece through the adhesive in the glue groove. A light guide structure for guiding external light into a photosensitive element is usually provided on the side of the glue groove facing the screen display area, resulting in an increase in the size of the display screen black border of the electronic device (the sum of the width of the glue groove and the width of the light guide structure), which reduces the area of the effective display area. During assembly, the adhesive may also overflow to the light guide structure, affecting the light guide performance of the light guide structure, and the assembly requirements are high.

[0036] In addition, in the related art, a transparent soft silicone spray coated with a black light shielding material is usually used as the light guide structure of the photosensitive element. When manufacturing the light guide structure, the black light shielding material needs to be sprayed on the surface of the transparent soft silicone, and then the light entrance position and the light exit position are engraved to form the light entrance surface and the light exit surface. The engraving may cause impurities to remain on the light entrance surface and the light exit surface and cannot guarantee smoothness, resulting in light loss.

[0037] To solve the problems in the related art, the embodiments of the present disclosure provide a display module and an electronic device. The display module includes a protective cover plate, a display film layer, and a sealing part. The sealing part is connected with the protective cover plate and the display film layer to block water vapor from entering the display film layer. The sealing part is made of a light-transmitting material. In the stacking direction of the protective cover plate and the display film layer, the first side of the sealing part is connected with the light entrance area of the protective cover plate to form a light entrance surface, and the second side of the sealing part faces the photosensitive element of the electronic device to form a light exit surface. In the present disclosure, the sealing part is made of a light-transmitting material, which can not only provide sealing and waterproof for the protective cover plate and the display film layer, but also transmit light to guide ambient light to irradiate the photosensitive element. Therefore, it is not necessary to provide a glue groove, which is beneficial to reduce the black border size of the edge of the display module, thereby improving the screen-to-body ratio of the electronic device. In addition, the present disclosure avoids the situation that the adhesive in the glue groove contaminates the sealing part during assembly, which is beneficial to improve the product yield.

[0038] According to an example embodiment of the present disclosure, as shown in Figure 1 and Figure 2 The present embodiment provides a display module 100 applied to an electronic device to enable the electronic device to have the function of displaying image information. The electronic device can be, for example, a smart phone, a tablet computer, a notebook computer, a remote controller, a smart wearable device, etc.

[0039] As shown in Figure 2As shown, the display module 100 includes a protective cover plate 10 and a display film layer 20, the protective cover plate 10 and the display film layer 20 are stacked, and the protective cover plate 10 can provide protection for the display film layer 20 and other components in the electronic device. The protective cover plate 10 is, for example, a transparent glass cover plate. The transparent glass cover plate can allow external ambient light to enter the electronic device to be collected by the photosensitive element 300 (to be described in detail below), and can also allow light emitted by the display film layer 20 to be transmitted through the protective cover plate 10 for display. The display film layer 20 is formed by stacking a plurality of display functional layers. Depending on the display film layer 20, the display module 100 can also be different. The display module 100 can be, for example, an LCD screen or an OLED screen. The display film layer 20 is a mature prior art, and the present embodiment does not limit the display film layer 20 too much.

[0040] Referring to Figure 2 , the protective cover plate 10 is provided with a light inlet area 11. The light inlet area 11 has a higher light transmittance than other areas of the protective cover plate 10, so that more ambient light can enter the electronic device through the light inlet area 11 to improve the detection accuracy of the photosensitive element 300. In one example, the display area 100a of the display module 100 has a low light transmittance. If the photosensitive element 300 is arranged below the display area 100a, it is easy to cause the photosensitive element 300 to detect inaccurately (i.e., under-screen light sensing technology). Therefore, the light inlet area 11 can be arranged at the edge of the protective cover plate 10, i.e., the non-display area 100b.

[0041] As shown in Figure 2 , the display module 100 further includes a sealing portion 30. The sealing portion 30 is connected to the protective cover plate 10 and the display film layer 20. The sealing portion 30 is used to prevent water vapor from entering between the plurality of display functional layers of the display film layer 20, and to prevent water vapor from entering between the protective cover plate 10 and the display functional layer, so as to avoid water vapor causing the display film layer 20 to corrode or short circuit. In one example, referring to Figure 2 , the sealing portion 30 covers the side edges of the display film layer 20, and the side of the protective cover plate 10 facing the display film layer 20, and the side of the display film layer 20 facing away from the protective cover plate 10. Therefore, the sealing portion 30 can provide sufficient protection for the display module 100.

[0042] Referring to Figure 2 and Figure 3The sealing part 30 is made of a light-transmitting material. A first side of the sealing part 30 is connected to the light-in area 11 of the protective cover plate 10 and forms a light-in surface 30a. A second side of the sealing part 30 faces the photosensitive element 300 in the electronic device and forms a light-out surface 30b. Thus, the sealing part 30 can serve as a light guide of the display module 100, so that external ambient light can be transmitted along a preset path to the photosensitive element 300 in the electronic device. The photosensitive element 300 of the electronic device is, for example, an ambient light sensor. The control part (not shown in the figure) of the electronic device can adjust the display color temperature and display brightness of the display module 100 according to the ambient light collected by the photosensitive element 300, so that the display module 100 displays a soft picture and appropriate brightness. The material of the sealing part 30 includes, but is not limited to, transparent soft silicone.

[0043] In the embodiments of the present disclosure, the sealing part 30 is made of a light-transmitting material. The sealing part 30 can not only provide sealing and waterproof for the protective cover plate 10 and the display film layer 20, but also can transmit and guide ambient light to irradiate the photosensitive element 300. Therefore, it is not necessary to set a glue groove, which is beneficial to reduce the size of the black border at the edge of the display module 100, thereby improving the screen-to-body ratio of the electronic device. In addition, the situation that the glue in the glue groove pollutes the sealing part 30 during assembly is avoided, which is beneficial to improve the product yield.

[0044] In one example embodiment, as shown in Figure 1 and Figure 2 , the present embodiment provides a display module 100. The display module 100 includes a protective cover plate 10, a display film layer 20, and a sealing part 30. The sealing part 30 is connected to the protective cover plate 10 and the display film layer 20 to block water vapor from entering the display film layer 20. The sealing part 30 is made of a light-transmitting material. In the stacking direction of the protective cover plate 10 and the display film layer 20, a first side of the sealing part 30 is connected to the light-in area 11 of the protective cover plate 10 to form a light-in surface 30a. A second side of the sealing part 30 faces a photosensitive element 300 of an electronic device to form a light-out surface 30b.

[0045] As shown in Figure 2 , the side of the protective cover plate 10 facing the display module is provided with a black matrix layer 12 (BM for short). The projection of the light-in surface 30a on the cover plate body falls within the range of the black matrix layer 12. Figure 2 In the z direction shown in , the black matrix layer 12 is opposite to the non-display area 100b of the display module 100.

[0046] In one example, the region of the black matrix layer 12 opposite to the light-in area 11 is provided with infrared ink (also referred to as IR ink). The infrared ink can transmit infrared light and block visible light and ultraviolet light, so as to avoid the photosensitive element 300 from being affected by other light and causing inaccurate detection results. The infrared ink can be formed on the black matrix layer 12 in a silk printing manner.

[0047] In another example, the area of the black matrix layer 12 opposite to the light-in area 11 is provided with a uniform light ink. The uniform light ink can make the ambient light diffuse and uniformly enter the electronic device, improving the detection accuracy of the light detection. The uniform light ink can also be formed on the black matrix layer 12 by silk printing.

[0048] In yet another example, the area of the black matrix layer 12 opposite to the light-in area 11 is provided with both infrared light ink and uniform light ink, which will not be described again.

[0049] In the embodiment, by providing the infrared light ink and the uniform light ink in the area of the black matrix layer 12 opposite to the light-in area 11, the specific light can be more uniformly incident into the electronic device, and the light detected by the light sensing element 300 is closer to the actual external situation, which is beneficial to improve the accuracy of the result generated by the light sensing element 300, thereby improving the display effect of the display module 100.

[0050] According to an example embodiment of the present disclosure, as shown in Figure 1 and Figure 2 The present embodiment provides an electronic device, which includes a middle frame structure 200, a light sensing element 300 and a display module 100. The middle frame structure 200 is arranged between the protective cover plate 10 and the back shell of the electronic device, and has the function of mounting various electronic devices of the electronic device, such as a mainboard, a battery, a camera module and various sensors. The light sensing element 300 provided in the present embodiment is one or more of the various sensors, such as an ambient light sensor.

[0051] The display module 100 in the present embodiment can be the display module 100 provided in any of the foregoing embodiments, so that the electronic device provided in the present disclosure has all the technical effects of the display module 100 provided in the present disclosure. For example, the sealing part 30 for sealing and protecting the display film layer 20 and the protective cover plate 10 is made of a light-transmitting material, without the need to arrange an additional light guide structure, which is beneficial for assembly; and the light-in surface 30a can be arranged close to the edge of the display module 100, which is beneficial for reducing the size of the black border of the edge of the display module 100, so that the electronic device has a higher screen-to-body ratio.

[0052] As shown in Figure 2 , the display film layer 20 of the display module 100 and the middle frame structure 200 enclose a light-in channel 400, which includes a first channel 60, a second channel 70 and a third channel 80 connected in sequence. The extension directions of the first channel 60 and the third channel 80 are parallel to the thickness direction (z direction) of the electronic device, and the extension direction of the second channel 70 is parallel to the length direction (x direction) of the electronic device. Figure 2 Figure 2 ​The x-direction shown is parallel, that is, the extension directions of the first channel 60 and the third channel 80 are parallel, and both are perpendicular to the extension direction of the second channel 70.

[0053] See Figure 2 The middle frame structure 200 partially forms the first reflective surface 40 and the second reflective surface 50, in the extending direction of the second channel 70 ( Figure 2 In the x direction shown, the first reflective surface 40 and the second reflective surface 50 are respectively disposed at the two ends of the second channel 70. The first reflective surface 40 and the second reflective surface 50 can change the light path of the light incident into the light inlet channel 400. While ensuring that the incident direction and the exit direction remain unchanged, the positions of the incident surface and the exit surface can be adjusted, which is beneficial to the layout of the internal components of the electronic device.

[0054] For example, see Figure 2 The first reflecting surface 40 is disposed at the end of the second channel 70 connected to the first channel 60. The plane containing the first reflecting surface 40 has a first angle with the z-direction shown in Figure 2. Taking the first angle as an example, the first angle is equal to 45°, and the light rays in the first channel 60 can travel along... Figure 2 As shown, when light from the first channel 60 shines back onto the first reflective surface 40 in the z-direction, it is certain that the light will be reflected when it hits the first reflective surface 40, thus changing the light path. The ambient light after the change in the light path will then travel along... Figure 2 The ray travels in the x-direction as shown and forms the first reflected ray. (Continue reading...) Figure 2 The second reflective surface 50 is located at the end where the second channel 70 and the third channel 80 are connected, and the plane where the second reflective surface 50 is located is parallel to the plane of the third channel 80. Figure 2 The z-direction shown has a second included angle. Taking a second included angle of 45° as an example, it can be determined that when the first reflected ray hits the second reflecting surface 50, reflection will occur, thus changing the light path. The first reflected ray after changing the light path will then travel along... Figure 2 The reverse travel in the z-direction shown in the figure forms a second reflected ray, which then enters the photosensitive element 300.

[0055] In some alternative implementations, the first included angle and the second included angle can also be other values, as long as the incident direction and the exit direction of the light are kept consistent.

[0056] Among them, see Figure 2 A reflection enhancement layer is provided on at least one of the first reflective surface 40 and the second reflective surface 50. The reflection enhancement layer can reduce the reflection loss of light on the reflective surface, thereby reducing the difference in light between the incident light surface 30a and the emitting light surface 30b, and thus improving the detection accuracy of the photosensitive element 300. In one example, the reflection enhancement layer may be a high-reflectivity metal coating.

[0057] Among them, seeFigure 2 Along the extension direction of the second channel 70 ( Figure 5 (As shown in the x-direction), the side of the sealing part 30 away from the display film layer 20 is bonded to the side of the middle frame structure 200 to form a seal. The assembly gap 500 between the middle frame structure 200 and the protective cover plate 10 is connected to the sealing part 30. That is, the sealing part 30 can prevent external moisture from entering the light-gathering channel 400 through the assembly gap 500 between the middle frame structure 200 and the protective cover plate 10. As can be seen from the above, in the electronic device provided in this embodiment, the sealing part 30 is made of a light-transmitting material, so that the sealing part 30 can not only provide a seal and waterproof for the protective cover plate 10 and the display film layer 20, but also allow light to pass through and guide ambient light to illuminate the photosensitive element 300. There is no need to set up a glue groove, which helps to reduce the size of the black border at the edge of the display module 100, thereby increasing the screen ratio of the electronic device. It also avoids the situation where the adhesive in the glue groove contaminates the sealing part 30 during assembly, which helps to improve the product yield.

[0058] In one exemplary embodiment, such as Figure 6 As shown, this embodiment provides an electronic device, which includes a mid-frame structure 200, a photosensitive element 300, and a display module 100. The display module 100 includes a protective cover plate 10, a display film layer 20, and a sealing part 30. The sealing part 30 is connected to the protective cover plate 10 and the display film layer 20 to prevent moisture from entering the display film layer 20. The sealing part 30 is made of a light-transmitting material. In the stacking direction of the protective cover plate 10 and the display film layer 20, the first side of the sealing part 30 is connected to the light-incident area 11 of the protective cover plate 10 to form a light-incident surface 30a, and the second side of the sealing part 30 faces the photosensitive element 300 of the electronic device to form a light-emitting surface 30b.

[0059] The electronics provided in this embodiment may include the various structural devices of the display module 100 provided in any of the foregoing embodiments, or the various structures and devices of the electronic device provided in any of the foregoing embodiments.

[0060] The sealing portion 30 of the display module 100 at least fills the first channel 60 of the light inlet channel 400.

[0061] In some embodiments, see Figure 2 The sealing portion 30 is columnar and fills only within the first channel 60. A light-emitting surface 30b is formed at the end of the sealing portion 30 facing the first reflective surface 40. This arrangement reduces the material used in the sealing portion 30, thereby lowering costs.

[0062] In other embodiments, the sealing portion 30 is L-shaped to fill the first channel 60 and extend into the second channel 70. In one example, see [reference needed]. Figure 3, part of the structure of the sealing part 30 extends into the second channel 70, but does not adhere to the second reflecting surface 50, so that the sealing part 30 can seal and protect the side of the display film layer 20 away from the protective cover plate 10. In another example, referring to Figure 2 and Figure 2 , the sealing part 30 includes a first light guide structure 31 and a second light guide structure 32, the first light guide structure 31 is arranged in the first channel 60, the second light guide structure 32 is arranged in the second channel 70, and the extension direction of the second light guide structure 32 is perpendicular to the extension direction of the first light guide structure 31. The two ends of the second light guide structure 32 respectively adhere to the first reflecting surface 40 and the second reflecting surface 50, and the surface of the second light guide structure 32 opposite to the third channel 80 forms the light emitting surface 30b. By arranging the sealing part 30 to adhere to the first reflecting surface 40 and the second reflecting surface 50, the loss of part of the first reflected light due to the diffuse reflection of the inner wall of the second channel 70 can be avoided, so as to ensure the intensity of the light entering the photosensitive element 300, and the installation reliability of the fixing part can be enhanced.

[0063] , referring to Figure 2 , the side of the second light guide structure 32 away from the first light guide structure 31 is flush with the second channel 70 along the extension direction of the first channel 60 (z direction shown in Figure 4 ), so that the light emitting surface 30b is parallel to the light entering surface 30a, and the sealing part can be easily installed into the light entering channel 400.

[0064] , in combination with ​ and ​ , the display module 100 and the middle frame structure 200 of the electronic device provided by the embodiment can be assembled in the following way:

[0065] First, at least one of the infrared ink and the uniform light ink is formed on the black matrix area of the protective cover plate 10 by using the silk screen process.

[0066] Then, the sealing part 30 is placed in a mold with a specific cavity, and the sealing part 30 is cured.

[0067] Then, the first reflecting surface 40 and the second reflecting surface 50 are arranged on the middle frame structure 200, and a reflection enhancement layer is plated on the first reflecting surface 40 and the second reflecting surface 50.

[0068] Finally, the display module 100 and the middle frame structure 200 are assembled, and part of the surface of the sealing part 30 adheres to the first reflecting surface 40 and the second reflecting surface 50.

[0069] Other embodiments of the disclosure will be apparent to those skilled in the art from consideration of the specification and practice of the embodiments disclosed herein. It is intended that the disclosure be construed as including any patents, patent applications, publications, publications, or other disclosure that modifies or adds to the function or characteristics of any devices disclosed herein.
