Description

Technical Field

[0001] This application relates to the field of electronic equipment technology, and in particular to a display module and electronic equipment. Background Technology

[0002] With the rapid development of technology, the use of electronic devices such as mobile phones, tablets, and televisions is becoming increasingly common. Electronic devices typically include display modules such as LCD (Liquid Crystal Display) modules. The light source of the display module can be multiple LED (Light Emitting Diode) lamps. However, LED lamps are prone to collisions during reliability testing or user use, which can cause them to detach from their installation position or malfunction and fail to emit light, resulting in a deterioration in the display effect of the display module and affecting its reliability. Utility Model Content

[0003] In view of this, this application provides a display module and electronic device that can prevent the light-emitting components from being impacted, ensure the display effect of the display module, and improve the reliability of the display module.

[0004] Specifically, the following technical solutions are included:

[0005] In a first aspect, this application provides a display module, the display module comprising:

[0006] The frame includes a first side frame and a second side frame connected together, the first side frame and the second side frame being arranged at an included angle;

[0007] A light guide is disposed on the first frame portion;

[0008] A light-emitting component includes a light source, the light-emitting component is connected to the light guide, the light-emitting component and the second frame portion are spaced apart along a first direction, and the distance between the light source and the second frame portion is D1;

[0009] A buffer component is connected to the light-emitting component. The buffer component and the second frame portion are spaced apart along a first direction. The distance between the buffer component and the second frame portion is D2, which satisfies: D2 < D1.

[0010] In the technical solution of this application, by setting a buffer component, and the distance D2 between the buffer component and the second frame is less than the distance D1 between the light source and the second frame, when the display module is impacted by an external force, the buffer component will contact the second frame before the light-emitting component, avoiding direct collision between the light-emitting component and the second frame, thus protecting the light-emitting component, reducing the possibility of damage to the light source, ensuring that the display module has a good display effect, and improving the reliability of the display module.

[0011] In one possible implementation, the buffer assembly includes a metal component.

[0012] In the technical solution of this application, by setting metal parts, the structural rigidity and impact resistance of the buffer component are increased, ensuring that energy can be effectively dispersed when subjected to force, reducing the impact force transmitted to the light-emitting component, thereby improving the protection effect of the light-emitting component; and compared with non-metallic materials, metal parts provide higher durability and thermal conductivity, which is beneficial for heat dissipation and extending the service life of the display module.

[0013] In one possible implementation, the buffer assembly further includes a shock absorber disposed between the metal component and the light-emitting component.

[0014] In the technical solution of this application, the shock absorber, as a second-level buffer structure other than the metal part, can absorb and dissipate the residual impact transmitted by the metal part, further reduce the vibration or impact transmitted by the metal part to the light-emitting component, enhance the buffering and vibration reduction effect, and reduce the failure rate of the light source.

[0015] In one possible implementation, the dimension of the metal part in the first direction is greater than or equal to the dimension of the light-emitting component in the first direction.

[0016] In the technical solution of this application, the size of the metal part in the impact direction (i.e. the first direction) is greater than or equal to the size of the light-emitting component. The metal part can cover the orthogonal projection area of ​​the light-emitting component on the metal part, which is beneficial to fully disperse the impact force when the display module is impacted, improve the uniformity of the force on the light-emitting component, ensure that the metal part contacts the frame first, and avoid the light-emitting component directly colliding with the frame.

[0017] In one possible implementation, the second frame portion has a buffer surface at one end away from the first frame portion, and the metal part is disposed opposite to the buffer surface along the first direction.

[0018] In the technical solution of this application, the buffer surface provides a stable impact surface for the metal part, which can ensure that the end face of the metal part is uniformly stressed, avoid damage to the metal part due to local stress concentration, and help extend the service life of the metal part.

[0019] In one possible implementation, the display module further includes a display component and an adhesive layer disposed between the display component and the buffer component.

[0020] In the technical solution of this application, the adhesive layer achieves the bonding between the display component and the buffer component, improves the connection stability between the display component and the buffer component, and makes the display component and the buffer component less prone to loosening or displacement.

[0021] In one possible implementation, the adhesive layer is connected to the side surface of the second frame portion opposite to the first frame portion, thereby covering the gap between the buffer assembly and the second frame portion.

[0022] In the technical solution of this application, the adhesive layer fully covers the gap between the buffer component and the second frame, which can not only prevent dust, moisture and other substances from entering the display module and avoid causing light source corrosion or short circuit, but also prevent light from leaking from the gap, which is beneficial to improving the display effect of the display module.

[0023] In one possible implementation, the following condition is satisfied: 0.1mm ≤ D1 ≤ 0.4mm.

[0024] In the technical solution of this application, by setting the value of D1 between 0.1mm and 0.4mm, it can provide space for the deformation of the light guide component due to thermal expansion and contraction, avoid accidental touch caused by the light-emitting component being too close to the second frame, and ensure the compactness of the display module structure, so as to avoid the large distance between the light-emitting component and the second frame affecting the thinning of the side frame of the display module.

[0025] In one possible implementation, the light-emitting component further includes a flexible circuit board connected to the light source, the flexible circuit board being bonded to the light guide, and the light source and the light guide being arranged along the first direction and abutting against each other.

[0026] In the technical solution of this application, the contact between the light source and the light guide can improve the light transmission efficiency and reduce the loss of light; the bonding between the flexible circuit board and the light guide improves the connection reliability between the light-emitting component and the light guide, and prevents the relative displacement between the light-emitting component and the light guide from causing flickering or color deviation and affecting the display effect.

[0027] In one possible implementation, the flexible circuit board is located on the side of the light guide away from the first frame portion, and the flexible circuit board is connected to the buffer assembly.

[0028] In the technical solution of this application, the light-emitting component can be assembled with the buffer component and the first reflective sheet first, and then directly assembled into the L-shaped frame with the upper opening to cooperate with the light guide. There is no need to assemble the light-emitting component and the light guide before assembling the buffer component and the first reflective sheet, which reduces the difficulty of the assembly process and helps to improve the assembly efficiency.

[0029] In one possible implementation, the display module further includes a first reflector disposed on the side of the shock absorber near the light-emitting component, and a portion of the first reflector covers the side surface of the light guide that is away from the first frame portion.

[0030] In the technical solution of this application, the first reflector is set on the side of the shock absorber close to the light-emitting component. This not only fixes the first reflector, but also reflects the light emitted by the light-emitting component at the edge of the light guide to the light guide, intercepts edge light leakage, and improves light utilization and display uniformity.

[0031] In one possible implementation, the display module further includes a second reflector disposed between the first frame portion and the light guide portion, with the light source spaced apart from the first frame portion.

[0032] In the technical solution of this application, the second reflector is used to recover the light refracted onto the first frame and reflect the light to the light guide. With the cooperation of the first reflector and the second reflector, the light utilization rate and the display uniformity of the display module are fully improved.

[0033] Secondly, this application provides an electronic device, which includes the display module provided in any embodiment of the first aspect. Attached Figure Description

Detailed Implementation

[0051] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

These directional terms are used merely to more clearly describe the relationships between structures, not to describe absolute directions.

[0053] Unless otherwise defined, all technical terms used in the embodiments of this application have the same meaning as commonly understood by one of ordinary skill in the art.

[0054] To make the technical solutions and advantages of this application clearer, the embodiments of this application will be described in further detail below with reference to the accompanying drawings.

[0055] With the rapid development of technology, the use of electronic devices such as mobile phones, tablets, and televisions is becoming increasingly common. Electronic devices typically include display modules such as LCD (Liquid Crystal Display) modules. The light source of the display module can be multiple LED (Light Emitting Diode) lamps. However, LED lamps are prone to collisions during reliability testing or user use, which can cause them to detach from their installation position or malfunction and fail to emit light, resulting in a deterioration in the display effect of the display module and affecting its reliability.

[0056] Figure 1 This is a cross-sectional view of a display module in related technologies. Figure 2 This is a front view of a display module in related technologies. For example... Figure 1 and Figure 2 As shown, the display module includes a metal frame 100, a light guide plate 200, LED lights 300, and a flexible printed circuit board (FPC) 400. The metal frame 100 is U-shaped and includes a bottom wall, side walls, and a top wall connected in sequence. The bottom wall and top wall are arranged opposite each other along the vertical direction shown in the figure. The LED lights 300 are connected to the flexible printed circuit board 400. Multiple LED lights 300 are arranged in a straight line on the flexible printed circuit board 400. The flexible printed circuit board 400 is connected to the light guide plate 200 by adhesive 500. The flexible printed circuit board 400 extends with a connecting part 401 for connecting to an LED connector. Because the light guide plate 200 expands and contracts with temperature, a gap is provided between the LED lights 300 and the side walls of the metal frame 100 (i.e., Figure 1 (The gap shown).

[0057] like Figure 3 As shown, when the display module in the related technology is dropped, the light guide plate 200 will shift, causing the flexible printed circuit board 400 to move. This causes the flexible printed circuit board 400 to collide with the side wall of the iron frame 100. Simultaneously, the LEDs 300 will shift or tilt due to the impact, resulting in changes to the linearity of the arrangement of multiple LEDs 300 on the flexible printed circuit board 400 and the elevation angle of each individual LED 300 relative to the surface of the flexible printed circuit board 400. This causes uneven brightness at the lamp openings of the display module, degrading the display effect. Furthermore, the large gap between the LEDs 300 and the side wall of the iron frame 100 results in a large side bezel of the display module, hindering the improvement of the screen-to-body ratio of the electronic device.

[0058] To address the aforementioned technical problems, this application provides a display module and electronic device that can prevent the light-emitting components from being impacted, ensure the display effect of the display module, and improve the reliability of the display module.

[0059] like Figure 4 and Figure 5 As shown, the display module provided in this embodiment includes a frame 1, a light guide 2, a light-emitting component 3, and a buffer component 4. Exemplarily, the display module is an LCD display module.

[0060] The frame 1 includes a first frame portion 11 and a second frame portion 12 connected together, with the first frame portion 11 and the second frame portion 12 arranged at an included angle. A light guide 2 is disposed on the first frame portion 11. A light-emitting component 3 includes a light source 31, which is connected to the light guide 2. The light-emitting component 3 and the second frame portion 12 are spaced apart along a first direction X, and the distance between the light source 31 and the second frame portion 12 is D1. A buffer component 4 is connected to the light-emitting component 3, which is spaced apart along the first direction X, and the distance between the buffer component 4 and the second frame portion 12 is D2, satisfying: D2 < D1.

[0061] It is understandable that D1 is the distance between the light source 31 and a portion of the second frame portion 12 directly opposite to it in the first direction X, and D2 is the distance between the buffer component 4 and a portion of the second frame portion 12 directly opposite to it in the first direction X.

[0062] For example, such as Figure 4 As shown, the first direction X is horizontal, and the second direction Z is vertical. The first direction X is perpendicular to the second direction Z. The plane containing the first frame portion 11 is perpendicular to the second direction Z. The plane containing the second frame portion 12 is perpendicular to the first plane. The first frame portion 11 is perpendicular to the second frame portion 12. The cross-sectional shape of the frame 1 is approximately "L". The frame 1 surrounds the light guide 2 and provides protection for components such as the light guide 2 and the light-emitting assembly 3.

[0063] The frame 1 can be made of metal, plastic, or a composite material combining metal and plastic; this application does not impose any specific limitations on this.

[0064] exist Figure 1 In the related technologies shown, the iron frame 100 is U-shaped. After the flexible printed circuit board 400 and the light guide plate 200 are assembled, they need to be inserted obliquely into the U-shaped bend of the iron frame 100. During this process, because the space at the U-shaped bend of the iron frame 100 is relatively narrow, the LED lamp 300 may collide with the iron frame 100 and fail to emit light, resulting in an increased dead lamp rate and a decreased yield of the display module. Moreover, it places high demands on the assembly process.

[0065] The frame 1 of the display module provided in this application embodiment eliminates the traditional U-shaped bending design. Instead, it is composed of a first frame portion 11 and a second frame portion 12 forming a more open "L" shaped structure. During the assembly process of the light-emitting component 3, the collision between the light-emitting component 3 and the frame 1 can be effectively reduced, which is conducive to reducing the dead lamp rate of the display module, improving the yield of the display module, and reducing the requirements for the assembly process, which helps to reduce production costs.

[0066] For example, the light source 31 of the light-emitting component 3 is an LED, and there are multiple light sources 31. The multiple light sources 31 are distributed at intervals along a straight line so that the light-emitting component 3 presents a rectangular strip light-emitting array shape. The light guide 2 is a plate-shaped structure. The function of the light guide 2 is to convert the point light source 31 or line light source 31 generated by the light source 31 into a uniform surface light source 31, so as to achieve efficient light transmission and uniform distribution.

[0067] like Figure 4 As shown, the light guide 2 is located on one side of the first frame portion 11 in the second direction Z, the light-emitting component 3 is located on one side of the light guide 2 in the first direction X, and the light-emitting component 3 is located between the light guide 2 and the second frame portion 12. The buffer component 4 is located on one side of the light-emitting component 3 in the second direction Z, specifically on the side of the light-emitting component 3 away from the first frame portion 11.

[0068] Since D2 < D1, when the display module is impacted by an external force, in the first direction X, the buffer component 4 will contact the second frame portion 12 before the light-emitting component 3, so as to avoid the light-emitting component 3 directly colliding with the second frame portion 12, and prevent the light source 31 from being damaged by the collision, resulting in uneven brightness on the lamp port side of the display module.

[0069] For example, the buffer assembly 4 may include an elastic material, such as rubber, plastic, spring, or other materials with elastic deformation capabilities, to improve vibration damping capacity and achieve better vibration damping effect. The buffer assembly 4 may also include a metallic damping material, which has high strength and stiffness, and is not easily damaged while absorbing vibration energy. The buffer assembly 4 may also include a flexible material, such as foamed plastic or other foam damping materials.

[0070] The display module provided in this application embodiment has a buffer component 4. The distance D2 between the buffer component 4 and the second frame portion 12 is less than the distance D1 between the light source 31 and the second frame portion 12. When the display module is impacted by an external force, the buffer component 4 will contact the second frame portion 12 before the light-emitting component 3, thus preventing the light-emitting component 3 from directly colliding with the second frame portion 12. This protects the light-emitting component 3, reduces the possibility of damage to the light source 31, ensures that the display module has a good display effect, and improves the reliability of the display module.

[0071] In some embodiments, the buffer component 4 includes a metal part 41.

[0072] The metal part 41 is made of pure metal or alloy material. For example, the metal part 41 can be made of aluminum alloy, steel or other materials.

[0073] like Figure 4 As shown, the metal part 41 is in the form of a sheet or plate, and the metal part 41 is located above the light-emitting component 3.

[0074] By incorporating the metal component 41, the structural rigidity and impact resistance of the buffer component 4 are increased, ensuring that energy can be effectively dispersed when subjected to force, reducing the impact force transmitted to the light-emitting component 3, thereby improving the protection effect of the light-emitting component 3; in addition, compared with non-metallic materials, the metal component 41 provides higher durability and thermal conductivity, which is beneficial for heat dissipation and extending the service life of the display module.

[0075] In some embodiments, the buffer assembly 4 further includes a shock absorber 42 disposed between the metal part 41 and the light-emitting assembly 3.

[0076] For example, the shock absorber 42 can be made of rubber, silicone, foam, cushioning rubber layer, etc. Figure 4 As shown, the shock absorber 42 is located below the metal part 41 and above the light-emitting component 3. It plays a role in buffering and absorbing force between the metal part 41 and the light-emitting component 3. When the shock absorber 42 is a buffer adhesive layer, the shock absorber 42 not only achieves the bonding between the metal part 41 and the light-emitting component 3, but also provides a buffering and vibration reduction effect.

[0077] In this embodiment, the shock absorber 42 serves as a second-level buffer structure in addition to the metal component 41. It can absorb and dissipate the residual impact transmitted by the metal component 41, further reducing the vibration or impact transmitted by the metal component 41 to the light-emitting component 3, enhancing the buffering and vibration reduction effect, and reducing the failure rate of the light source 31.

[0078] In some embodiments, the size of the metal part 41 in the first direction X is greater than or equal to the size of the light-emitting component 3 in the first direction X.

[0079] Optionally, such as Figure 4 As shown, the end face of the metal part 41 near the second frame portion 12 is flush with the end face of the light-emitting component 3 near the second frame portion 12; or, the end face of the metal part 41 near the second frame portion 12 is closer to the second frame portion 12 than the end face of the light-emitting component 3 near the second frame portion 12. This arrangement ensures that when the display module is impacted, the metal part 41 contacts the second frame portion 12, preventing the light-emitting component 3 from directly colliding with the frame 1.

[0080] In this embodiment, the size of the metal part 41 in the impact direction (i.e., the first direction X) is greater than or equal to the size of the light-emitting component 3. The metal part 41 can cover the orthogonal projection area of ​​the light-emitting component 3 on the metal part 41, which is beneficial to fully disperse the impact force when the display module is impacted, improve the uniformity of the force on the light-emitting component 3, ensure that the metal part 41 contacts the frame 1 first, and avoid the light-emitting component 3 directly colliding with the frame 1.

[0081] In some embodiments, the second frame portion 12 has a buffer surface 121 at one end away from the first frame portion 11, and the metal part 41 is disposed opposite to the buffer surface 121 along the first direction X.

[0082] like Figure 4 and Figure 5 As shown, the buffer surface 121 is located at the upper end of the second frame portion 12, and the metal part 41 and the buffer surface 121 are directly opposite each other along the first direction X. The distance D1 between the buffer assembly 4 and the second frame portion 12 is the distance between the metal part 41 and the buffer surface 121 in the first direction X.

[0083] Optionally, the buffer surface 121 is planar. For example, the buffer surface 121 can be a plane perpendicular to the first direction X; or the buffer surface 121 can be a plane inclined to the first direction X. At the same time, the end face of the metal part 41 near the buffer surface 121 is also inclined to the first direction X, and the inclination angle of the end face is consistent with the inclination angle of the buffer surface 121, so that the end face and the buffer surface 121 can fit together, thereby increasing the contact area between the metal part 41 and the buffer surface 121 and improving the uniformity of the force on the metal part 41.

[0084] Optionally, the buffer surface 121 and the end face of the metal part 41 near the buffer surface 121 can also be mutually adapted curved surfaces, so that collision energy absorption can be achieved through the concave-convex fit between the buffer surface 121 and the end face of the metal part 41 near the buffer surface 121.

[0085] In this embodiment, the buffer surface 121 provides a stable impact surface for the metal part 41, which can ensure that the end face of the metal part 41 is subjected to uniform force, avoid damage to the metal part 41 due to local stress concentration, and help extend the service life of the metal part 41.

[0086] In some embodiments, the display module further includes a display component 5 and an adhesive layer 6, wherein the adhesive layer 6 is disposed between the display component 5 and the buffer component 4.

[0087] The adhesive layer 6 achieves the bonding between the display component 5 and the buffer component 4, improving the connection stability between the display component 5 and the buffer component 4, and making it less likely for the display component 5 and the buffer component 4 to loosen or shift.

[0088] Optionally, the adhesive layer 6 can be OCA optical adhesive, UV curable adhesive, etc., and this application does not make specific limitations on it.

[0089] like Figure 4 As shown, the display component 5 is generally located above the metal part 41 (i.e., on the side of the metal part 41 facing away from the light-emitting component 3). The display component 5 includes at least an upper polarizer 51, a color filter layer 52, a thin-film transistor layer 53, and a lower polarizer stacked along the second direction Z. The upper polarizer 51 and the lower polarizer are used to block light in a certain direction. The color filter layer 52 is used to control the color of the emitted light and realize color display. The thin-film transistor layer 53 is used to control the display of the display component 5. The display module also includes an optical film group 8, which is disposed between the display component 5 and the light guide 2. The optical film group 8 is used for light homogenization and light focusing to improve display uniformity and display effect.

[0090] In some embodiments, the adhesive layer 6 is connected to the side surface of the second frame portion 12 opposite to the first frame portion 11, thereby covering the gap between the buffer assembly 4 and the second frame portion 12.

[0091] like Figure 4 As shown, the adhesive layer 6 protrudes outward relative to the side end face of the metal part 41 near the buffer surface 121, so that the adhesive layer 6 connects with the second frame portion 12 while covering the gap between the metal part 41 and the second frame portion 12.

[0092] In this embodiment, the adhesive layer 6 fully covers the gap between the buffer component 4 and the second frame portion 12, which not only prevents dust, moisture and other substances from entering the interior of the display module and avoiding corrosion or short circuit of the light source 31, but also prevents the light source 31 from leaking light from the gap, which is beneficial to improving the display effect of the display module.

[0093] In some embodiments, the following condition is satisfied: 0.1mm≤D1≤0.4mm.

[0094] In related technologies, Figure 1 The gap shown is approximately 0.6mm. The horizontal distance between the LED 300 and the iron frame 100 is relatively large, resulting in a large side bezel of the display module, which hinders the improvement of the screen ratio of electronic devices.

[0095] In the display module provided in this application embodiment, since a buffer component 4 is provided to protect the light-emitting component 3, the distance D1 between the light-emitting component 3 and the second frame portion 12 of the frame 1 can be greatly reduced, effectively reducing the width of the side frame of the display module, which is beneficial to improving the screen ratio of the electronic device.

[0096] In this embodiment, by setting the value of D1 between 0.1mm and 0.4mm, it can provide space for the deformation of the light guide 2 due to thermal expansion and contraction, avoid accidental touch caused by the light-emitting component 3 being too close to the second frame portion 12, and ensure the compactness of the display module structure, so as to avoid the large distance between the light-emitting component 3 and the second frame portion 12 affecting the thinning of the side frame of the display module.

[0097] In some embodiments, the light-emitting component 3 further includes a flexible circuit board 32 connected to the light source 31. The flexible circuit board 32 is bonded to the light guide 2. The light source 31 and the light guide 2 are arranged along the first direction X and abut against each other.

[0098] like Figure 4 As shown, the flexible circuit board 32 and the light source 31 are distributed along the second direction Z. The flexible circuit board 32 and the light guide 2 are bonded together by the adhesive layer 321. The light source 31 is located on one side of the light guide 2 in the first direction X. The display module is a side-mounted display module.

[0099] The light source 31 is electrically connected to the flexible circuit board 32. The flexible circuit board 32 can be located on the side of the light source 31 close to the first frame portion 11, or on the side of the light source 31 away from the first frame portion 11.

[0100] like Figure 4 As shown, the display module also includes a PCB board 9 and a connector 10. The PCB board 9 and the connector 10 are located on the side of the first frame portion 11 away from the second frame portion 12. The flexible circuit board 32 can be electrically connected to the connector 10 after bending, so that the light-emitting component 3 can be electrically connected to other electronic devices through the connector 10.

[0101] In this embodiment, the light source 31 abuts against the light guide 2, which can improve the light transmission efficiency and reduce light loss; the flexible circuit board 32 is bonded to the light guide 2, which improves the connection reliability between the light-emitting component 3 and the light guide 2, and prevents relative displacement between the light-emitting component 3 and the light guide 2 from causing flickering or color deviation and affecting the display effect.

[0102] In some embodiments, the flexible circuit board 32 is located on the side of the light guide 2 away from the first frame portion 11, and the flexible circuit board 32 is connected to the buffer assembly 4.

[0103] Please refer to Figure 1 and Figure 4In related technologies, the flexible printed circuit board 400 is located below the LED lamp 300. The flexible printed circuit board 400 and the LED lamp 300 need to be assembled together with the light guide plate 200 first, and then assembled together into the U-shaped bent iron frame 100. However, in the embodiment of this application, the flexible circuit board 32 is located above the light source 31. The light-emitting component 3 can be assembled together with the buffer component 4 and other components first, and then directly assembled into the L-shaped frame 1 with the upper opening to cooperate with the light guide 2. There is no need to assemble the light-emitting component 3 and the light guide 2 in advance and then assemble the buffer component 4 and other components, which reduces the difficulty of the assembly process and helps to improve the assembly efficiency.

[0104] In some embodiments, the display module further includes a first reflector 71, which is disposed on the side of the shock absorber 42 near the light-emitting component 3, and a portion of the first reflector 71 covers the side surface of the light guide 2 opposite to the first frame portion 11.

[0105] like Figure 4 As shown, the first reflector 71 is located between the shock absorber 42 and the light-emitting component 3, and a portion of the first reflector 71 covers the upper surface of the light guide 2.

[0106] The first reflective element 71 can be a PET (polyethylene terephthalate) reflective sheet, composite film, etc., and this application does not make specific limitations on it.

[0107] By placing the first reflector 71 on the side of the shock absorber 42 close to the light-emitting component 3, not only is the first reflector 71 fixed, but the light emitted by the light-emitting component 3 at the edge of the light guide 2 is also reflected to the light guide 2, blocking edge light leakage and improving light utilization and display uniformity.

[0108] In some embodiments, the display module further includes a second reflector 72, which is disposed between the first frame portion 11 and the light guide 2, and the light source 31 is spaced apart from the first frame portion 11.

[0109] like Figure 4 As shown, the second reflector 72 is located below the light guide 2, and the first reflector 71 and the second reflector 72 are located on both sides of the light guide 2 in the second direction Z.

[0110] The second reflective element 72 can be a PET (polyethylene terephthalate) reflective sheet, composite film, etc., and this application does not make specific limitations on it.

[0111] By setting a second reflector 72, the light refracted onto the first frame portion 11 is recovered by the second reflector 72 and reflected to the light guide 2. With the joint cooperation of the first reflector 71 and the second reflector 72, the light utilization rate and the display uniformity of the display module are fully improved.

[0112] This application also provides an electronic device, which includes the display module provided in any of the above embodiments. Since the electronic device includes the display module of the above embodiments, it possesses all the advantages and functions of the display module, and will not be repeated here.

[0113] Electronic devices include, but are not limited to, mobile phones, laptops, tablets, e-book readers, wearable devices, navigators, handheld game consoles, virtual and reality devices, augmented reality devices, and televisions.
