[0023] Next, the technical solutions in the embodiments of the present application will be clearly described in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art belong to the scope of protection of the present application.

[0024] The terms "first", "second", etc. in the description and claims of this application are used to distinguish similar objects, rather than to describe a specific order or sequence. It should be understood that the data used in this way can be interchanged under appropriate circumstances, so that the embodiments of this application can be implemented in an order other than those illustrated or described herein, and the objects distinguished by "first", "second", etc. are generally of the same type, and do not limit the number of objects. For example, the first object can be one or more. In addition, "and / or" in the description and claims means at least one of the connected objects, and the character " / ", generally represents an "or" relationship between the associated objects before and after.

[0025] The following will combine the accompanying drawings and specifically illustrate the display module and the electronic device provided by the embodiments of this application through specific embodiments and their application scenarios.

[0026] As Figure 1 , Figure 2 and Figure 3 shown, the embodiment of this application provides a display module 100, and the display module 100 includes: a cover plate 1, a display panel 2, and an encapsulation layer 3. The cover plate 1 includes a main body portion 11 and a side wall 12. The side wall 12 is disposed on the main body portion 11, and the main body portion 11 and the side wall 12 enclose a receiving groove 13; the display panel 2 is disposed in the receiving groove 13; the encapsulation layer 3 encapsulates the side of the display panel 2 facing away from the main body portion 11, and at least a part of the encapsulation layer 3 is disposed in the receiving groove 13.

[0027] The display panel 2 is a screen body with light-emitting display capabilities. The display panel 2 can be a flexible display panel or a non-flexible display panel. The display panel 2 can include a pixel definition layer, a light-emitting device layer 21, and a driving circuit layer 22. The light-emitting device layer 21 includes a plurality of light-emitting units, and the pixel definition layer includes a plurality of pixel apertures. The light-emitting units are disposed within the pixel apertures. Exemplarily, in the embodiments of the present application, organic light-emitting diodes (OLEDs) can be selected to fabricate the above-mentioned respective light-emitting units. Alternatively, the light-emitting units can also be set as micro light-emitting diodes (Micro-LEDs) or quantum dot light-emitting diodes (QLEDs). The driving circuit layer 22 can include a plurality of sub-pixel control units for controlling whether the light-emitting units emit light and the light-emitting duration. The driving circuit layer 22 can include a gate metal layer, a source-drain metal layer, an active layer, etc. The display panel 2 of this embodiment can also include an insulating layer, an organic encapsulation layer, an inorganic encapsulation layer, a planarization layer, etc., which will not be elaborated one by one here. The display panel 2 can also include a substrate for supporting the driving circuit layer 22. When the display panel 2 is a flexible display panel 2, the material of the substrate includes flexible materials such as polyimide (PI).

[0028] The cover plate 1 is used to protect the display panel 2. The display panel 2 is received in the receiving groove 13, and the side wall 12 surrounds the display panel 2. The cover plate 1 can be made of materials such as glass, transparent ceramics, glass-ceramics, plastics, and resins. The main body portion 11 and the side wall 12 of the cover plate 1 can be an integrally formed structure. Taking the cover plate 1 as a glass cover plate as an example, a glass material with sufficient thickness can be taken first, and the glass material is processed by grooving to obtain a receiving groove 13 with sufficient depth. The middle region of the glass material forms the main body portion 11, and the edge region of the glass material forms the side wall 12.

[0029] The encapsulation layer 3 encapsulates the side of the display panel 2 facing away from the main body portion 11, thereby preventing external water and oxygen from entering the receiving groove 13 and increasing the service life of the display panel 2. The encapsulation layer 3 can also fix the display panel 2 in the receiving groove 13 to prevent relative displacement between the display panel 2 and the cover plate 1. The encapsulation layer 3 can be prepared by a sealant. After the display panel 2 is prepared in the receiving groove 13, or after the display panel 2 is assembled into the receiving groove 13, a sealant is filled on the side of the display panel 2 facing away from the main body portion 11, and the sealant is cured to form the encapsulation layer 3. The edge of the encapsulation layer 3 can be connected to the side wall 12, and the encapsulation layer 3 can also extend into the gap between the display panel 2 and the side wall 12. The encapsulation layer 3 can also be an insulating encapsulation layer or a heat-conducting encapsulation layer.

[0030] In the embodiments provided in the present application, by providing the cover plate 1 with a receiving groove 13, the display panel 2 is received in the receiving groove 13, thereby eliminating the need to provide an adhesive layer between the cover plate 1 and the display panel 2 and reducing the thickness of the display module 100; by providing the encapsulation layer 3 to encapsulate the side of the display panel 2 facing away from the main body portion 11, external water and oxygen can be prevented or reduced from entering the receiving groove 13, thereby improving the service life of the display panel 2.

[0031] In some embodiments, the display module 100 further includes a flexible circuit board 4 and a conductive film layer 5. At least a part of the flexible circuit board 4 is received in the receiving groove 13. The flexible circuit board 4 is disposed on the side of the display panel 2 facing away from the main body portion 11. The conductive film layer 5 is received in the receiving groove 13 and is disposed between the display panel 2 and the flexible circuit board 4. The conductive film layer 5 electrically connects the display panel 2 and the flexible circuit board 4.

[0032] The conductive film layer 5 can be directly formed on the display panel 2. The conductive film layer 5 is electrically connected to the driving circuit layer 22 in the display panel 2. The conductive end of the flexible circuit board 4 is pressed against the side of the conductive film layer 5 facing away from the display panel 2, thereby realizing the electrical connection between the conductive film layer 5, the display panel 2, and the flexible circuit board 4.

[0033] Compared with connecting the flexible circuit board 4 to the side of the display panel 2 close to the main body portion 11 and then bending the flexible circuit board 4 to the side of the display panel 2 facing away from the main body portion 11, by providing the conductive film layer 5 to electrically connect the display panel 2 and the flexible circuit board 4, the bending of the flexible circuit board 4 is eliminated, and the space reserved for bending the flexible circuit board 4 is eliminated, thereby reducing the thickness of the display module 100 and being beneficial to increasing the screen-to-body ratio of the display area in the display module 100.

[0034] In some embodiments, the conductive film layer 5 is an anisotropic conductive film (ACF) connection layer. The display panel 2 and the flexible circuit board 4 are electrically connected along the first direction X on opposite sides of the conductive film layer 5, while the peripheral side of the conductive film layer 5 perpendicular to the first direction X is not conductive, thereby improving the stability of the electrical signal transmission between the display panel 2 and the flexible circuit board 4.

[0035] In some embodiments, the display module 100 further includes a light-shielding layer 6. The light-shielding layer 6 is received in the receiving groove 13. The light-shielding layer 6 and the conductive film layer 5 are disposed on the surface of the display panel 2 facing away from the main body portion 11.

[0036] The light-shielding layer 6 has a low light transmittance or is light-impermeable. The light-shielding layer 6 is disposed on the side of the display panel 2 facing away from the main body portion 11 to improve the display effect of the display module 100. The light-shielding layer 6 can be prepared from an organic material or a metal. When the light-shielding layer 6 is prepared from a metal, the light-shielding layer 6 not only has a light-shielding effect but also has a heat dissipation function. Optionally, the light-shielding layer 6 is a copper foil.

[0037] The light-shielding layer 6 and the conductive film layer 5 are both formed on the surface of the display panel 2. The light-shielding layer 6 can be disposed corresponding to the display area of the display panel 2, and the conductive film layer 5 can be disposed corresponding to the non-display area of the display panel 2. The light-shielding layer 6 and the conductive film layer 5 can be disposed at intervals to prevent electrical conduction between the conductive film layer 5 and the light-shielding layer 6, and an insulating structure can also be filled between the light-shielding layer 6 and the conductive film layer 5. When the conductive film layer 5 is an anisotropic conductive film layer, the light-shielding layer 6 and the conductive film layer 5 can also be in adjacent contact to increase the distribution area of the light-shielding layer 6 and the conductive film layer 5. Since the conductive film layer 5 is an anisotropic conductive film layer, the mutually contacting light-shielding layer 6 and conductive film layer 5 are insulated from each other.

[0038] On the side of the display panel 2 facing away from the main body portion 11, a laminated structure formed of graphite, foam, a hard material layer, etc. can also be provided to reinforce the structure of the display panel 2. The hard material layer can be prepared from a hard material such as stainless steel (e.g., SUS).

[0039] In some embodiments, the display module 100 further includes a control module 7. The control module 7 is at least partially received in the receiving groove 13. The control module 7 is disposed on the side of the flexible circuit board 4 facing away from the main body portion 11. The encapsulation layer 3 covers at least a part of the control module 7, and the control module 7 is embedded in the encapsulation layer 3.

[0040] The control module 7 can be a module that controls the display module 100 to implement different functions. For example, the control module 7 can be a display control module that controls the display panel 2 to emit light and display, or can also be a touch control module that controls the touch response of the display panel 2. The control module 7 is disposed on the side of the display panel 2 facing away from the main body portion 11 to increase the screen-to-body ratio of the display module 100.

[0041] The control module 7 can be entirely received in the receiving groove 13, and the encapsulation layer 3 covers the surface of the control module 7 facing away from the main body portion 11. The control module 7 can also be partially received in the receiving groove 13, and the encapsulation layer 3 covers a part of the control module 7, and the surface of the control module 7 facing away from the main body portion 11 is exposed outside the encapsulation layer 3. By covering at least a part of the control module 7 with the encapsulation layer 3, the ability of the control module 7 to isolate water and oxygen is improved.

[0042] Please refer to Figure 4 and Figure 5 , in some embodiments, the display module 100 further includes a control module 7. The control module 7 is at least partially received in the receiving groove 13. The control module 7 is disposed on the side of the display panel 2 facing away from the main body portion 11. The control module 7, the driving circuit layer 22 of the display panel 2, and the flexible circuit board 4 are electrically connected in sequence. The encapsulation layer 3 covers at least a part of the control module 7, and the control module 7 is embedded in the encapsulation layer 3.

[0043] The control module 7 can be directly connected to the driving circuit layer 22 of the display panel 2, and electrically connected to the flexible circuit board 4 through the circuit in the driving circuit layer 22, and the flexible circuit board 4 is then connected to the external circuit, thereby eliminating the need to lay the flexible circuit board 4 on the control module 7 and the display panel 2, which is beneficial to reducing the thickness of the display module 100.

[0044] In some embodiments, the flexible circuit board 4 includes a first connection end 41 and a second connection end 42 that are electrically connected. The first connection end 41 is received in the receiving groove 13 and is electrically connected to the conductive film layer 5. The packaging layer 3, the first connection end 41, the conductive film layer 5 and the display panel 2 are stacked in sequence, and the second connection end 42 is located on the side of the packaging layer 3 away from the main body 11.

[0045] The first connection end 41 may include a plurality of conductive contacts, each of which is electrically connected to the circuit in the driving circuit layer 22 through the conductive film layer 5. The second connection end 42 may include a connector, and the flexible circuit board 4 is electrically connected to the external circuit through the connector. For example, the electronic device is a mobile phone, and the flexible circuit board 4 is electrically connected to the mainboard through the connector.

[0046] The first connection end 41 of the flexible circuit board 4 is encapsulated in the receiving groove 13 by the encapsulation layer 3, thereby ensuring the effective connection between the first connection end 41 and the conductive film layer 5; the second connection end 42 of the flexible circuit board 4 is located outside the encapsulation layer 3 to facilitate the assembly of the second connection end 42 and the connection with the external circuit. Optionally, a variety of electronic components can be arranged on the flexible circuit board 4, and the electronic components can be distributed outside the receiving groove 13 and arranged on the side of the flexible circuit board 4 away from the main body 11.

[0047] Please refer again Figure 3 In some embodiments, the surface of the encapsulation layer 3 facing away from the main body 11 and the surface of the side wall 12 facing away from the main body 11 are in the same reference plane, so that one side of the display module 100 has a flat surface, which facilitates the installation of the display module 100 on other planes. The flexible encapsulation glue can be filled into the receiving groove 13, and the surface of the flexible encapsulation glue and the surface of the side wall 12 facing away from the main body 11 are in the same reference plane. The surface of the encapsulation layer 3 facing away from the main body 11 and the surface of the side wall 12 facing away from the main body 11 formed by curing the flexible encapsulation glue are in the same reference plane.

[0048] The thickness of the side wall 12 along the first direction X is greater than the thickness of the main body 11 along the first direction X, ensuring the strength of the peripheral side of the display module 100, so that when the display module 100 is assembled to other structures, the thicker side wall 12 can be assembled with other structures. The main body 11 is thin and has good elasticity, and the side wall 12 is thick and has good strength, so that the cover plate 1 is not easy to break.

[0049] In some embodiments, the display module 100 further includes a light adjustment layer 8. The light adjustment layer 8 is disposed in the receiving groove 13, and the light adjustment layer 8 is disposed on the side of the display panel 2 close to the main body portion 11. The light adjustment layer 8 includes a first flat layer 81, a light filtering layer 82, and a second flat layer 83. The first flat layer 81 is disposed between the main body portion 11 and the light filtering layer 82, and the second flat layer 83 is disposed between the light filtering layer 82 and the display panel 2.

[0050] The light adjustment layer 8 can adjust the light emitted by the display panel 2 to reduce the reflection of the display module 100 and improve the brightness and contrast of the display module 100.

[0051] The first flat layer 81 can planarize the surface of the main body portion 11 close to the display panel 2 to provide a flat surface for forming the light adjustment layer 8. The second flat layer 83 can planarize the functional layer on the side of the display panel 2 close to the main body portion 11 to facilitate the installation or preparation of the display panel 2. The functional layer can be the light filtering layer 82. Optionally, the main body portion 11, the first flat layer 81, the light filtering layer 82, the second flat layer 83, and the display panel 2 are stacked in sequence.

[0052] The light filtering layer 82 can be a polarizing layer, and the polarizing layer can adopt a polyvinyl alcohol (PVA) film layer. Since the first flat layer 81 and the second flat layer 83 are provided, the protective layer adhesive layers for protecting the polarizing layer on the opposite sides of the polarizing layer can be omitted, reducing the thickness of the display module 100. For example, a triacetyl cellulose (TAC) film layer for protecting the polarizing layer.

[0053] The light filtering layer 82 can also be a color filter (CF). The color filter includes a plurality of light filtering units 821a. The light filtering units 821a can select the light waves in the desired passing band range and reflect the other bands that are not desired to pass, improving the color saturation of the display panel 2.

[0054] When preparing the display module 100, the cover plate 1 with the receiving groove 13 can be prepared first, and then the first flat layer 81, the light filtering layer 82, the second flat layer 83, the display panel 2, the flexible circuit board 4, and the encapsulation layer 3 can be sequentially disposed in the receiving groove 13. The display panel 2 can be prepared in the receiving groove 13. That is, when preparing the display panel 2, with the cover plate 1 as the substrate, the light emitting device layer 21 is prepared first, and then the driving circuit layer 22 is prepared.

[0055] In some embodiments, the display panel 2 includes a light-emitting device layer 21. The light-emitting device layer 21 includes a plurality of light-emitting units 211. The color filter layer 82 includes a plurality of color filter units 821a. The orthographic projection of the light-emitting unit 211 on the main body portion 11 and the orthographic projection of the color filter unit 821a on the main body portion 11 at least partially overlap.

[0056] The display panel 2 may further include a pixel definition layer having pixel openings, and the light-emitting units 211 are disposed within the pixel openings. The plurality of light-emitting units 211 may be light-emitting units 211 capable of emitting light of different colors respectively. For example, it may be a red light-emitting unit 211 capable of emitting red light, a green light-emitting unit 211 capable of emitting green light, and a blue light-emitting unit 211 capable of emitting blue light. The light-emitting units 211 may be arranged in one-to-one correspondence with the pixel openings.

[0057] The plurality of color filter units 821a may be color filter units 821a capable of transmitting light of different colors respectively. For example, it may be a red color filter unit 821a capable of transmitting red light, a green color filter unit 821a capable of transmitting green light, and a blue color filter unit 821a capable of transmitting blue light. The orthographic projection of the light-emitting unit 211 on the main body portion 11 and the orthographic projection of the color filter unit 821a on the main body portion 11 at least partially overlap, so that the light-emitting unit 211 and the color filter unit 821a are arranged in correspondence. The color filter unit 821a can transmit the light emitted by the corresponding light-emitting unit 211 and filter other colors of light. The red color filter unit 821a may be arranged in correspondence with the red light-emitting unit 211 to transmit the red light emitted by the red light-emitting unit 211. The green color filter unit 821a may be arranged in correspondence with the green light-emitting unit 211 to transmit the green light emitted by the green light-emitting unit 211. The blue color filter unit 821a may be arranged in correspondence with the blue light-emitting unit 211 to transmit the blue light emitted by the blue light-emitting unit 211. Unless otherwise specified, the orthographic projection on the main body portion 11 in this application is the orthographic projection on the main body portion 11 along the first direction X. The first direction X may be the thickness direction of the display module 100 or the direction perpendicular to the surface of the cover plate 1 facing away from the display panel 2.

[0058] The color filter layer 82 may further include a light-blocking portion, and the light-blocking portion may be disposed between adjacent color filter units 821a, thereby reducing the mixing of light emitted by adjacent light-emitting units 211.

[0059] Please refer to Figure 6 , in some embodiments, the color filter layer 82 includes a plurality of color filter groups 821, and the color filter group 821 includes a plurality of color filter units 821a;

[0060] The light adjustment layer 8 includes a first lens layer 84. The first lens layer 84 is located on the side of the light filtering layer 82 close to the main body 11. A first flat layer 81 covers the side of the first lens layer 84 close to the main body 11. The first lens layer 84 includes a plurality of first lens structures 841. The first lens structures 841 are convex lenses. The surface of the first lens structure 841 close to the main body 11 is a convex surface. The orthographic projection of the first lens structure 841 on the main body 11 overlaps with the orthographic projection of the light filtering group 821 on the main body 11.

[0061] A plurality of light emitting units 211 can form a light emitting group, and a plurality of light emitting groups are arranged in an array. The light filtering units 821a in the light filtering group 821 and the light emitting units 211 in the light emitting group can be correspondingly arranged. For example: the light emitting group includes 1 red light emitting unit 211, 1 blue light emitting unit 211, and 2 green light emitting units 211, and the light filtering group 821 includes 1 red light filtering unit 821a, 1 blue light filtering unit 821a, and 2 green light filtering units 821a.

[0062] By setting the orthographic projection of the first lens structure 841 on the main body 11 to overlap with the orthographic projection of the light filtering group 821 on the main body 11, a first lens structure 841 can refract a part of the light emitted from the light filtering group 821 to one direction, such as the left eye of the user, and the first lens structure 841 can also refract another part of the light emitted from the light filtering group 821 to one direction, such as the right eye of the user, so that the left and right eyes of the user can see different lights, realizing 3D stereoscopic display.

[0063] For example: the light filtering group 821 includes 2 sub - groups. One sub - group includes 1 red light filtering unit 821a, 1 blue light filtering unit 821a, and 1 green light filtering unit 821a, and the other sub - group includes 1 red light filtering unit 821a, 1 blue light filtering unit 821a, and 1 green light filtering unit 821a. The orthographic projection of the first lens structure 841 on the main body 11 covers the orthographic projections of 2 red light filtering units 821a, 2 blue light filtering units 821a, and 2 green light filtering units 821a on the main body 11. The two sub - groups are arranged at intervals along the second direction Y. A plurality of light filtering groups 821 are arranged along the second direction Y to form a light filtering column, and the light filtering columns are arranged at intervals along the third direction Z. When the user uses the display module 100, the second direction Y can be the direction of the line connecting the user's two eyes. The first lens structure 841 can refract the light emitted from one sub - group of the light filtering group 821 to the right eye of the user, and refract the light emitted from the other sub - group of the light filtering group 821 to the left eye of the user, realizing 3D stereoscopic display.

[0064] In some embodiments, the light adjustment layer 8 includes a second lens layer 85. The second lens layer 85 is located on the side of the light filtering layer 82 away from the main body portion 11. A second flat layer 83 covers the side of the second lens layer 85 away from the main body portion 11. The second flat layer 83 includes a plurality of second lens structures 851. The second lens structures 851 are convex lenses. The surface of the lens structure away from the main body portion 11 is a convex surface. The orthographic projection of the second lens structure 851 on the main body portion 11 overlaps with the orthographic projection of the light filtering unit 821a on the main body portion 11.

[0065] The second lens layer 85 may be a microprism structure. The second lens layer 85 can concentrate the light emitted by the light emitting unit 211. The light emitting unit 211 and the second lens structure can be arranged in one-to-one correspondence. Both the first lens structure 841 and the second lens structure 851 can be prepared from a resin material with high light transmittance and high refractive index to achieve the refraction effect of light.

[0066] Please refer to Figure 7 and Figure 8 In some embodiments, the display module 100 includes at least one bent display area AA1 and a plurality of non-bent display areas AA2. The at least one bent display area AA1 divides the display module 100 into a plurality of non-bent display areas AA2. The cover plate 1 further includes a groove 14 provided in the main body portion 11. The groove 14 is located in the bent display area. The display module 100 further includes a buffer layer 9. The buffer layer 9 is disposed in the groove 14. The elasticity of the buffer layer 9 is greater than that of the main body portion 11.

[0067] The display module 100 can be used to display images. The display module 100 has a folded state and an unfolded state. When the display module 100 is folded, at least a part of the bent display area bends into an arc around the bending axis. The non-bent display areas AA2 connected to the bent display area AA1 can be stacked, so as to reduce the volume of the flexible display module 100. When the bent display area is unfolded, the bent display area AA1 and the non-bent display areas AA2 connected to the bent display area AA1 can be flattened and displayed together, so as to obtain a larger display area. Optionally, the number of the bent display areas AA1 can be one, and the number of the non-bent display areas AA2 is two. The two non-bent display areas AA2 are disposed on both sides of the bending axis.

[0068] The buffer layer 9 can be formed by filling a groove 14 with an elastic transparent resin or the like. When the display module 100 is switched from the unfolded state to the folded state, there is an outward bending force on each layer structure in the display module 100. The buffer layer 9 can absorb this outward bending force, and after each layer structure in the display module 100 is bent, it can be partially received in the groove 14, thereby reducing the fracture of the bent display area and improving the problem of film layer fracture caused by stress concentration. The thinner the thickness of the cover plate 1, the smaller the bending radius. Optionally, the thickness of the cover plate 1 is 1um - 1000um, the thickness of the main body portion 11 located in the bent display area AA1 is 30um, the thickness of the main body portion 11 located in the non-bent display area AA2 is 80um, and the thickness of the side wall 12 is 600um.
