Description

Technical Field

[0001] The embodiments of the present application relate to the technical field of electronic devices, and in particular to a display module and an electronic device. Background Art

[0002] With the development of electronic devices, the demand for display performance of display modules is getting higher and higher. Correspondingly, in order to improve the performance of display modules, the size of various electronic components in display modules is getting larger and larger. For example, in order to improve the display performance, the driver chip of the display module is getting larger and larger. The driver chip is a semiconductor component, generally in a long strip shape, and is relatively brittle.

[0003] When an existing display module is subjected to a frontal impact, electronic components in the display module are easily damaged (for example, a driver chip is broken), causing the entire display module to be scrapped. Utility Model Content

[0004] The embodiments of the present application provide a display module and an electronic device, which are used to solve the problem that electronic components of the existing display module are easily damaged when subjected to a frontal impact.

[0005] In order to achieve the above purpose, the embodiment of the present application adopts the following technical solution:

[0006] In a first aspect, an embodiment of the present application provides a display module, including a display panel, a back panel, a protective plate and electronic components.

[0007] The display panel includes a display area, a bending area and a component arrangement area, and the display area and the component arrangement area are connected through the bending area. The display area and the component arrangement area are respectively located on both sides of the back plate, and a first groove is provided on the side of the back plate facing the display area. The protective plate is fixed in the first groove, one side surface of the protective plate is in contact with the display area, and there is a gap between the other side surface of the protective plate and the bottom surface of the first groove. The electronic component is arranged on a side surface of the component arrangement area away from the back plate, and the vertical projection of the protective plate on the component arrangement area covers the vertical projection of the electronic component on the component arrangement area.

[0008] The display module provided in the first aspect of the present application is configured by opening a first groove on a side of a back panel facing a display area, fixing a protective plate in the first groove, and providing a gap between the protective plate and a bottom surface of the first groove, so that the vertical projection of the protective plate on the component arrangement area covers the vertical projection of the electronic component on the component arrangement area.

[0009] In this way, when the display module is impacted from the front (i.e., the display area side), on the one hand, due to the high strength of the protective plate (for example, made of high-modulus titanium alloy, stainless steel, aluminum alloy, etc.), it can withstand a large impact without deformation, which is equivalent to making it difficult for the component arrangement area opposite to the protective plate to deform. The difficulty in deformation of the component arrangement area will not easily cause deformation and fracture of the electronic components. On the other hand, the transmission path of the impact force in the thickness direction of the display module will be blocked by the above-mentioned gap, so that the impact force will not be transmitted to the electronic components through the back plate and the component arrangement area, thereby reducing the risk of electronic components being fractured by the impact force.

[0010] In combination with the first aspect, in a possible implementation, the display module further includes a supporting rib, the protective plate includes a first area and a second area, the supporting rib is arranged in the first area of ​​the protective plate, and the supporting rib is connected to the bottom surface of the first groove. The vertical projection of the second area of ​​the protective plate on the component arrangement area of ​​the display panel covers the vertical projection of the electronic component on the component arrangement area of ​​the display panel.

[0011] In this way, due to the presence of the supporting ribs, after the protective plate is embedded in the first groove, the supporting ribs abut against the bottom surface of the first groove, so that there is still the above-mentioned gap between the second area of ​​the protective plate and the bottom surface of the first groove, and there is no need to fix the protective plate separately on the back plate, which simplifies the installation process. For example, a transition fit is adopted between the protective plate and the first groove, and the protective plate and the supporting ribs are integrally formed. When installing, it is only necessary to insert the protective plate into the first groove and make the supporting ribs abut against the bottom surface of the first groove. When the protective plate is subjected to an impact force along the thickness direction of the display module, due to the supporting effect of the supporting ribs, the protective plate will not move toward the electronic component, that is, it is ensured that the above-mentioned gap always exists between the second area of ​​the protective plate and the bottom surface of the first groove. In addition, the impact force acting on the protective plate will be transmitted to the back plate through the supporting ribs, and the transmission path of the impact force from the second area to the electronic component will be blocked by the above-mentioned gap, thereby reducing the risk of the electronic component being broken by the impact force.

[0012] In combination with the first aspect, in another possible implementation manner, the first area of ​​the protective plate extends around the second area.

[0013] In combination with the first aspect, in another possible implementation, the support ribs extend around the second area of ​​the protective plate. With this arrangement, the support ribs provide more balanced support for the protective plate. When the display module is subjected to a frontal impact, the impact force acting on the protective plate can be evenly transmitted and dispersed to the back plate through the support ribs, so that the protective plate is evenly stressed and will not tilt or shift.

[0014] In combination with the first aspect, in another possible implementation, a plurality of support ribs are provided, and the plurality of support ribs are spaced apart in the first region of the protective plate. For example, the plurality of support ribs are equally spaced around the second region in the first region, so that the support ribs provide more balanced support to the protective plate. When the display module is subjected to a frontal impact, the impact force acting on the protective plate can be evenly transmitted and dispersed to the back plate through the support ribs, so that the protective plate is evenly stressed and does not tilt or shift.

[0015] In combination with the first aspect, in another possible implementation, the protective plate is provided with a plurality of first regions, and a plurality of supporting ribs are provided, and the plurality of supporting ribs correspond one to one with the plurality of first regions. For example, the plurality of first regions are evenly distributed on the entire protective plate, so that the supporting ribs support the protective plate more evenly, and when the display module is subjected to a frontal impact, the impact force acting on the protective plate can be evenly transmitted and dispersed to the back plate through the supporting ribs, so that the protective plate is evenly stressed everywhere without tilting or shifting.

[0016] In combination with the first aspect, in another possible implementation, the protective plate and the supporting ribs are integrally formed. Thus, the protective plate and the supporting ribs are integrally formed, which has a higher structural strength and can withstand greater impact. In addition, the integral forming is convenient for production and processing (for example, one-step forming by stamping, casting, etc.), thereby reducing production costs.

[0017] In combination with the first aspect, in another possible implementation, a second groove is formed on the bottom surface of the first groove, the support rib extends into the second groove, and the support rib is connected to the bottom surface of the second groove. This arrangement is equivalent to clamping the support rib in the second groove, which can prevent the protective plate from being displaced due to excessive impact force transmitted to the support rib when subjected to a large impact.

[0018] In combination with the first aspect, in another possible implementation, the display module further includes a first buffer, and the support ribs are connected to the bottom surface of the second groove through the first buffer. The first buffer may be made of elastic materials such as colloid and foam double-sided tape. For example, the first buffer is a colloid. In this way, on the one hand, the first buffer can be used to bond and fix the support ribs in the second groove, thereby fixing the protective plate. On the other hand, it is also equivalent to using the first buffer to separate the support ribs from the bottom surface of the second groove. When the display module is subjected to a frontal impact and the impact force is transmitted to the protective plate and the support ribs, the elastic deformation of the first buffer can be used to release part of the impact force (that is, the mechanical energy of the protective plate and the support ribs is converted into the internal energy of the first buffer), thereby further improving the protection of electronic components.

[0019] In combination with the first aspect, in another possible implementation, the display module also includes a second buffer, and the support ribs are connected to the side walls of the second groove and the side walls of the first groove through the second buffer. Among them, the first buffer can be made of elastic materials such as colloid and foam double-sided tape. For example, the second buffer is a colloid. In this way, the second buffer can not only be used to bond and fix the support ribs in the first groove and the second groove, so as to achieve the fixation of the protective plate. In addition, the second buffer can also be used to fill the gap between the support ribs and the side walls of the first groove and the side walls of the second groove to prevent the support ribs and the protective plate from shifting. In addition, the second buffer can also produce a certain degree of elastic deformation to release part of the impact force, further improving the protection of electronic components.

[0020] In combination with the first aspect, in another possible implementation, the display module further includes a third buffer, and the protective plate is connected to the display area through the third buffer. The third buffer may be made of elastic materials such as colloid and foam double-sided tape. For example, the third buffer is a foam double-sided tape, so that the third buffer can be used not only to bond the protective plate to the display area of ​​the display panel, but also to eliminate the step difference between the side of the protective plate facing the display area and the side of the back plate facing the display area, thereby ensuring the flatness of the display area and the back plate after bonding.

[0021] In combination with the first aspect, in another possible implementation, the display module further includes a gasket, one side surface of the gasket is bonded to the back plate, and the other side surface of the gasket is bonded to the component arrangement area of ​​the display panel. In this way, the gasket is used to increase the distance between the display area and the component arrangement area of ​​the display panel, which is equivalent to reducing the curvature of the bending area and increasing the curvature radius of the bending area, thereby reducing the risk of damage to the bending area due to excessive bending angle (for example, the cable in the bending area is broken, etc.).

[0022] In combination with the first aspect, in another possible implementation, the gasket covers the component arrangement area of ​​the display panel. In this way, the gasket covers the component arrangement area of ​​the display panel, thereby ensuring the flatness of the component arrangement area after being attached to the back plate.

[0023] In a second aspect, the present application provides an electronic device, which includes a housing, a mainboard, and the display module of the first aspect, wherein the mainboard is disposed in the housing, the display module is mounted on the housing, and the display module is electrically connected to the mainboard.

[0024] It can be understood that the beneficial effects that can be achieved by the electronic device described in the second aspect and any possible implementation thereof provided above can refer to the beneficial effects in the first aspect and any possible implementation thereof, and will not be repeated here.

The "quantity" mentioned above cannot be understood as limiting the present application.

[0051] In the description of this application, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0052] The embodiment of the present application provides an electronic device 01. Specifically, the electronic device 01 may be a portable electronic device or other types of electronic devices. For example, the electronic device may be a mobile phone, a tablet personal computer, a personal digital assistant (PDA), a monitor, a wearable device, etc. For the convenience of explanation, the following examples are all taken as an example of the electronic device 01 being a mobile phone.

[0053] See also Figure 1 and Figure 2 As shown, Figure 1 This is a schematic diagram of the overall structure of the electronic device 01 provided in the embodiment of the present application. Figure 2 For the above Figure 1 Exploded diagram of the structure of the electronic device 01. As can be seen from the above, in this embodiment, the electronic device 01 is a mobile phone, and the electronic device 01 can be in an approximately rectangular plate-shaped structure. The electronic device 01 can include a screen assembly 10, a housing 20, a camera module 30, a mainboard 40, a camera decorative cover 50 and a battery 60.

[0054] For the convenience of the following description, an XYZ coordinate system is established, and the width direction of the electronic device 01 is defined as the X-axis direction, the length direction of the electronic device 01 is defined as the Y-axis direction, and the thickness direction of the electronic device 01 is defined as the Z-axis direction. Therefore, this application does not make any special restrictions on this. It can be understood that Figure 1 and Figure 2 Only some components of the electronic device 10 are schematically shown, and the actual shapes, sizes, positions and structures of these components are not subject to the present invention. Figure 1 and Figure 2 restrictions.

[0055] The housing 20 is used to protect the electronic components inside the electronic device 01. The housing 20 may include a battery cover 21 and a frame 22. The battery cover 21 is fixed to the frame 22. For example, the battery cover 21 may be fixed to the frame 22 by bonding, threading, welding, or snapping.

[0056] The camera module 30 is used to realize video or image shooting and can realize auto focus (AF, AutoFocus), so it can be applied to various shooting scenes. Figure 1 As shown, the camera module 30 is arranged near a side edge of the rear cover 21. Alternatively, the camera module 30 may be located at a middle position of the upper portion of the rear cover 21 (not shown in the figure). Therefore, the specific position of the camera module 30 is not particularly limited in this application.

[0057] The camera decorative cover 50 is used to prevent foreign objects such as dust from outside from entering the electronic device 01 or the camera module 30, and to prevent the camera module 30 from being scratched or hit by external objects.

[0058] The mainboard 40 is used to set the electronic devices of the electronic device 10 and realize the electrical connection between the electronic devices. The battery 60 is electrically connected to the mainboard 40 to provide power to the electronic devices. Exemplarily, the electronic devices may be a control chip (e.g., a system on chip, SOC), a graphics processing unit (GPU), a universal flash storage (UFS), an earpiece, a flash module, and the camera module 30.

[0059] The above-mentioned screen assembly 10 is used to display images, videos, etc. The screen assembly 10 may include a light-transmitting cover plate 11 and a display module 12, and the light-transmitting cover plate 11 and the display module 12 are stacked. The material of the light-transmitting cover plate 11 includes but is not limited to glass. For example, the light-transmitting cover plate 11 can adopt an ordinary light-transmitting cover plate to protect the display module 12 to avoid damage to the display module 12 due to external force, and can play a dust-proof role. Alternatively, the light-transmitting cover plate 11 can also adopt a light-transmitting cover plate with a touch function, so that the electronic device 01 has a touch function, which makes it more convenient for users to use. Therefore, the present application does not specifically limit the specific material of the light-transmitting cover plate 11.

[0060] The above-mentioned light-transmitting cover plate 11 and battery cover 21 are respectively arranged on both sides of the frame 22. The light-transmitting cover plate 11 can be fixed on the frame 22 by gluing, so that the light-transmitting cover plate 11, the battery cover 21 and the frame 22 form a receiving cavity inside the electronic device 01, and the above-mentioned display module 12, main board 40, camera module 30 and battery 60 are all arranged in the receiving cavity.

[0061] See also Figure 3 , Figure 4 As shown, Figure 3 A front view (parallel to the Z axis) of the display module 12 provided in the embodiment of the present application. Figure 4 A schematic diagram of a cross section (parallel to the YZ plane) at AA of a display module 12 provided in an embodiment of the present application. Specifically, the above-mentioned display module 1212 may include a display panel 121, a back plate 122 and an electronic component 125. Among them, the display panel 121 includes a display area 1211, a bending area 1212 and a component arrangement area 1213, and the display area 1211 and the component arrangement area 1213 are connected through the bending area 1212. The display area 1211 and the component arrangement area 1213 are arranged opposite to each other and are respectively located on both sides of the back plate 122, and the electronic component 125 is arranged on a side surface of the component arrangement area 1213 away from the back plate 122. The back plate 122 can be made of titanium alloy, stainless steel, aluminum alloy, etc. with high strength to serve as the supporting body of the entire display module 12.

[0062] The electronic component 125 may be a driving chip, a chip capacitor, a controller, etc. of the display panel 121 , and the present application does not impose any special limitation on this.

[0063] The above-mentioned display panel 121 can be an organic light-emitting diode (OLED) display panel 121, an active-matrix organic light-emitting diode or an active-matrix organic light-emitting diode (AMOLED) display panel, a mini organic light-emitting diode (mini organic light-emitting diode) display panel, a micro light-emitting diode (micro light-emitting diode) display panel, a micro organic light-emitting diode (micro organic light-emitting diode) display panel, a quantum dot light emitting diode (QLED) display panel, a liquid crystal display (LCD) panel, etc.

[0064] In some embodiments, in order to prevent the bending area 1212 of the display panel 121 from being damaged due to excessive bending angle (for example, the cable in the bending area 1212 is broken, etc.), the display module 12 may further include a gasket 126. Figure 4 As shown, the gasket 126 is disposed between the component arrangement area 1213 and the back plate 122, one side surface of the gasket 126 is in contact with the back plate 122, and the other side surface of the gasket 126 is in contact with the component arrangement area 1213. In this way, the gasket 126 increases the distance between the display area 1211 and the component arrangement area 1213, which is equivalent to reducing the curvature of the bending area 1212 and increasing the curvature radius of the bending area 1212, thereby preventing the bending angle of the bending area 1212 from being too large.

[0065] Furthermore, the gasket 126 covers the component arrangement area 1213 , so that the flatness of the component arrangement area 1213 after being bonded to the gasket 126 can be ensured.

[0066] In some embodiments, the display module 12 may further include a polarizer 128. The polarizer 128 may be attached to the side of the display area 1211 away from the back plate 122 by optical adhesive (OCA). The polarizer 128 is used to enhance the contrast and color expression of the display area 1211, and can reduce the reflection and glare of external light to a certain extent, thereby improving the visibility of the display module 12.

[0067] For ease of understanding, the following descriptions are all made by taking the electronic component 125 as a driver chip as an example. The driver chip is a semiconductor component, which is generally in the shape of a long strip and is relatively brittle and is easily broken when impacted.

[0068] In general, in order to reduce the deformation of the electronic component 125 when the display module 12 is impacted from the front (ie, the side of the display area 1211), please continue to refer to Figure 4 As shown, a steel sheet 129 is further arranged between the back plate 122 and the component arrangement area 1213. The vertical (parallel to the Z axis) projection of the steel sheet 129 on the component arrangement area 1213 covers the vertical (parallel to the Z axis) projection of the electronic component 125 on the component arrangement area 1213, that is, in the illustrated orientation, the steel sheet 129 is located directly above the electronic component 125.

[0069] Among them, since the two sides of the steel sheet 129 are directly in contact with the back plate 122 and the component layout area 1213, when the display module 12 is subjected to a frontal impact, the impact force will still be directly transmitted to the electronic component 125 in the thickness direction of the display module 12 through the polarizer 128, the display area 1211, the back plate 122, the steel sheet 129 and the component layout area 1213, which may cause the electronic component 125 to break and cause the entire display module 12 to be scrapped.

[0070] To solve the above problems, the present application provides another display module 12, see Figure 5 , Figure 6 As shown, Figure 5 This is a schematic diagram of a cross section (parallel to the YZ plane) of another display module 12 at AA provided in an embodiment of the present application. Figure 6 for Figure 5 An enlarged view of the first groove 1221 in FIG.

[0071] The display module 12 may include a protective plate 123, as well as the polarizer 128, a display panel 121, a back plate 122, a protective plate 123, an electronic component 125, and a gasket 126. The display area 1211 and the component arrangement area 1213 of the display panel 121 are arranged opposite to each other and are respectively located on both sides of the back plate 122, and are connected through the bending area 1212. The polarizer 128 is arranged on a side of the display area 1211 away from the back plate 122, the electronic component 125 is arranged on a side surface of the component arrangement area 1213 away from the back plate 122, and the gasket 126 is arranged between the back plate 122 and the component arrangement area 1213.

[0072] The back plate 122 has a first groove 1221 on one side facing the display area 1211. The protective plate 123 is fixed in the first groove 1221, one side surface of the protective plate 123 is in contact with the display area 1211, and a gap 100 is formed between the other side surface of the protective plate 123 and the bottom surface of the first groove 1221. The vertical (parallel to the Z axis) projection of the protective plate 123 on the component arrangement area 1213 covers the vertical (parallel to the Z axis) projection of the electronic component 125 on the component arrangement area 1213.

[0073] The protective plate 123 may be made of a relatively high-strength metal or non-metal, such as a high-modulus titanium alloy, stainless steel, aluminum alloy, carbon fiber, and the like.

[0074] In this way, when the display module 12 is impacted from the front (i.e., the display area 1211 side), on the one hand, due to the high strength of the protection plate 123, it can withstand a large impact without deformation, which is equivalent to making it difficult for the component arrangement area 1213 located directly below the protection plate 123 to deform. The component arrangement area 1213 is difficult to deform and will not easily cause the electronic component 125 to deform or break ( Figure 6 The dashed box in the middle refers to the electronic component 125, and the component arrangement area 1213 and the gasket 126 between the electronic component 125 and the back plate 122 are omitted and not drawn). On the other hand, the transmission path of the impact force in the thickness direction of the display module 12 will be blocked by the above-mentioned gap 100, so that the impact force will not be transmitted to the electronic component 125 through the back plate 122 and the component arrangement area 1213, thereby reducing the risk of the electronic component 125 being broken by the impact force.

[0075] It is understandable that the protective plate 123 can be fixed in the first groove 1221 on the back plate 122 by bonding, clamping, welding, riveting, etc., and the present application does not make any special limitation on this.

[0076] The cross-sectional shape (parallel to the XY plane) of the protective plate 123 can be a regular or irregular shape such as a rectangle, trapezoid, circle, or ellipse, as long as the vertical (parallel to the Z axis) projection of the protective plate 123 on the component layout area 1213 can be covered by the vertical (parallel to the Z axis) projection of the electronic component 125 on the component layout area 1213. This application does not impose any special restrictions on this.

[0077] For ease of understanding, the following descriptions are all based on examples in which the protective plate 123 is a rectangular plate structure.

[0078] For example, see Figure 6 shown. Figure 6In the figure, the cross section of the protective plate 123 (parallel to the XY plane) is rectangular, and accordingly, the cross section of the first groove 1221 (parallel to the XY plane) is also rectangular, and the thickness of the protective plate 123 (parallel to the Z axis) is less than the depth of the first groove 1221 (parallel to the Z axis). After the protective plate 123 is embedded in the first groove 1221, in the orientation shown in the figure, the upper surface of the protective plate 123 and the upper surface of the back plate 122 are in the same plane, the side wall of the protective plate 123 and the side wall of the first groove 1221 are welded together (the black area C in the figure is a welding point), and there is a gap of 100 between the lower surface of the protective plate 123 and the bottom surface of the first groove 1221.

[0079] At this time, the electronic component 125 is located directly below the protective plate 123 (i.e., the electronic component 125 is located directly below the gap 100). With this arrangement, when the protective plate 123 is impacted, the transmission path of the impact force F from the protective plate 123 to the electronic component 125 will be blocked by the gap 100 and will not be transmitted to the electronic component 125.

[0080] On the basis of the above, the display module 12 may further include a supporting rib 124, see Figure 7 As shown, Figure 7 A schematic diagram of a cross section (parallel to the YZ plane) at the first groove 1221 in another display module 12 provided in an embodiment of the present application. The protective plate 123 includes a first area 1231 and a second area 1232, and the support rib 124 is disposed in the first area 1231 of the protective plate 123, and the support rib 124 is connected to the bottom surface of the first groove 1221. The vertical projection of the second area 1232 of the protective plate 123 on the component arrangement area 1213 covers the vertical projection of the electronic component 125 on the component arrangement area 1213.

[0081] In this way, due to the existence of the supporting ribs 124, after the protective plate 123 is embedded in the first groove 1221, there is still the above-mentioned gap 100 between the second area 1232 of the protective plate 123 and the bottom surface of the first groove 1221, so there is no need to fix the protective plate 123 on the back plate 122 separately, which simplifies the installation process. When the protective plate 123 is subjected to the impact force F along the thickness direction of the display module 12, due to the supporting effect of the supporting ribs 124, the protective plate 123 will not move toward the electronic component 125, that is, it is ensured that the above-mentioned gap 100 always exists between the second area 1232 of the protective plate 123 and the bottom surface of the first groove 1221.

[0082] In addition, the impact force F acting on the protective plate 123 will be transmitted to the back plate 122 through the supporting ribs 124, and the transmission path of the impact force F from the second area 1232 to the electronic component 125 will be blocked by the gap 100, thereby reducing the risk of the electronic component 125 being broken by the impact force ( Figure 7 The dashed box in the middle refers to the electronic component 125, and the component arrangement area 1213 and the gasket 126 between the electronic component 125 and the back plate 122 are omitted and not drawn).

[0083] It is understandable that the protective plate 123 and the supporting ribs 124 can be connected by welding, bonding, clamping, etc. Alternatively, the protective plate 123 and the supporting ribs 124 can also be connected to form an integral structure, that is, the protective plate 123 and the supporting ribs 124 form a structural component as a whole, and there is no separation fault between the two. Compared with the split structure, the integral structure is more solid and easy to manufacture (for example, one-time molding by stamping, casting, 3D printing, etc.), thereby reducing production costs.

[0084] For example, see Figure 7 As shown. The cross-section (parallel to the XY plane) of the protective plate 123 and the cross-section (parallel to the XY plane) of the first groove 1221 are both rectangular, and a transition fit is adopted between the protective plate 123 and the first groove 1221, and the protective plate 123 and the supporting rib 124 are integrally formed, the first area 1231 is located on both sides of the second area 1232, and the supporting rib 124 is arranged close to the edge of the protective plate 123. During installation, the protective plate 123 is inserted into the first groove 1221, and the supporting rib 124 is abutted against the bottom surface of the first groove 1221, and there is a gap 100 between the second area 1232 of the protective plate 123 and the bottom surface of the first groove 1221.

[0085] In some embodiments, see Figure 8 As shown, Figure 8 A schematic diagram of the connection between a protective plate 123 and a supporting rib 124 provided in an embodiment of the present application, wherein a first region 1231 of the protective plate 123 extends around a second region 1232 .

[0086] In this case, the supporting rib 124 may extend around the second area 1232 of the protective plate 123. Alternatively, a plurality of supporting ribs 124 may be provided, and the plurality of supporting ribs 124 are arranged at intervals in the first area 1231 of the protective plate 123.

[0087] In this way, the support ribs 124 provide more balanced support for the protective plate 123. When the display module 12 is subjected to a frontal impact, the impact force acting on the protective plate 123 can be evenly transmitted and dispersed to the back plate 122 through the support ribs 124, so that the protective plate 123 is evenly stressed and will not tilt or shift.

[0088] For example, see Figure 8 , Fig. 9As shown, the cross-section (parallel to the XY plane) of the protection plate 123 is rectangular, and the second region 1232 is also rectangular and located in the middle of the protection plate 123. The first region 1231 is rectangular and extends along the edge of the protection plate 123. Correspondingly, the cross-section (parallel to the XY plane) of the support rib 124 is also rectangular and extends along the first region 1231.

[0089] For another example, see Fig. 9 As shown, Fig. 9 Another connection diagram of a protective plate 123 and a supporting rib 124 provided in an embodiment of the present application. The cross-section (parallel to the XY plane) of the protective plate 123 is rectangular, and the second region 1232 is also rectangular and is located in the middle of the protective plate 123. The first region 1231 is a rectangular ring and extends along the edge of the protective plate 123. There are four supporting ribs 124, namely, the first supporting rib 124a, the second supporting rib 124b, the third supporting rib 124c and the fourth supporting rib 124d. The first supporting rib 124a, the second supporting rib 124b, the third supporting rib 124c and the fourth supporting rib 124d are respectively arranged at the four vertex positions of the protective plate 123.

[0090] In other embodiments, see Fig.10 As shown, Fig.10 A schematic diagram of another connection between a protective plate 123 and a supporting rib 124 provided in an embodiment of the present application. In particular, a plurality of first regions 1231 of the protective plate 123 are provided, and a plurality of supporting ribs 124 are also provided, and the plurality of supporting ribs 124 correspond one to one with the plurality of first regions 1231. In this arrangement, the impact force acting on the protective plate 123 can also be evenly transmitted and dispersed to the back plate 122 through the supporting ribs 124, so that the protective plate 123 is evenly stressed at all locations without tilting or shifting.

[0091] For example, see Fig.10 As shown, Fig.10 In the figure, the cross section (parallel to the XY plane) of the protective plate 123 is rectangular, the first area 1231 and the second area 1232 are also rectangular, and the first area 1231 is provided with two, namely the first sub-area 123a and the second sub-area 123b. The second area 1232 is provided with one, and the first sub-area 123a and the second sub-area 123b are respectively located on both sides of the second area 1232. The supporting rib 124 is a rectangular strip, and the supporting rib 124 is provided with two, namely the first rib and the second rib, the first supporting rib 124a is located in the first sub-area 123a, and the second supporting rib 124b is located in the second sub-area 123b.

[0092] The above merely illustrates some possible distribution modes of the first area 1231 or the supporting ribs 124 on the protective plate 123, and does not constitute a special limitation on the present application. Those skilled in the art may make adjustments according to actual needs.

[0093] For further information, see Fig.11 As shown, Fig.11 A schematic diagram of a cross section (parallel to the YZ plane) of another display module 12 at the first groove 1221 provided in an embodiment of the present application. A second groove 1222 is also provided on the bottom surface of the first groove 1221, and the support rib 124 extends into the second groove 1222, and the support rib 124 is connected to the bottom surface of the second groove 1222. In this way, it is equivalent to clamping the support rib 124 in the second groove 1222, which can prevent the protective plate 123 from being too large when being subjected to a large impact, and causing the support rib 124 to shift.

[0094] For example, see Fig.12 As shown, Fig.12 for Figure 8 Schematic diagram of the corresponding support rib 124 and the second groove 1222. Fig.17 The second groove 1222 on the bottom surface of the first groove 1221 is Fig. 9 That is, the cross section (parallel to the XY plane) of the first groove 1221 is rectangular, and the cross section (parallel to the XY plane) of the second groove 1222 is rectangular and extends along the bottom edge of the first groove 1221.

[0095] For another example, see Fig.13 As shown, Fig.13 for Fig. 9 Schematic diagram of the corresponding support rib 124 and the second groove 1222. Fig.18 The second groove 1222 on the bottom surface of the first groove 1221 is Fig.11 That is, the cross section (parallel to the XY plane) of the first groove 1221 is rectangular, and the second groove 1222 is provided with four, namely, the first sub-groove 122a, the second sub-groove 122b, the third sub-groove 122c and the fourth sub-groove 122d, which are respectively provided at the four vertex positions of the bottom surface of the first groove 1221.

[0096] For another example, see Fig.14 As shown, Fig.14 for Fig.10 Schematic diagram of the corresponding support rib 124 and the second groove 1222. Fig.19The second groove 1222 on the bottom surface of the first groove 1221 is Fig.13 That is, the cross section (parallel to the XY plane) of the first groove 1221 is rectangular, the second groove 1222 is provided with two, namely the first sub-groove 122a and the second sub-groove 122b, the cross sections (parallel to the XY plane) of the first sub-groove 122a and the second sub-groove 122b are also rectangular, the first sub-groove 122a and the second sub-groove 122b are respectively located on both sides of the bottom surface of the first groove 1221, the first supporting rib 124a extends into the first sub-groove 122a, and the second supporting rib 124b extends into the second sub-groove 122b.

[0097] On the basis of the above, see Fig.15 As shown, Fig.15 A schematic diagram of a cross section (parallel to the YZ plane) of another display module 12 at the first groove 1221 provided in an embodiment of the present application. The display module 12 may further include a first buffer 127a, and the support rib 124 is connected to the bottom surface of the second groove 1222 through the first buffer 127a.

[0098] The first buffer member 127a may be made of elastic materials such as colloid, foam double-sided tape, etc.

[0099] For example, see Fig.15 As shown, the first buffer 127a is a colloid, and the first buffer 127a completely covers the bottom surface of the second groove 1222. In the illustrated orientation, the upper surface of the protective plate 123 and the upper surface of the back plate 122 are in the same plane, and the lower surface of the supporting rib 124 is completely in contact with the first buffer 127a.

[0100] In this way, on the one hand, the first buffer member 127a can be used to bond and fix the support rib 124 in the second groove 1222, thereby fixing the protective plate 123. On the other hand, the first buffer member 127a is used to separate the support rib 124 from the bottom surface of the second groove 1222. When the display module 12 is impacted from the front and the impact force F is transmitted to the protective plate 123 and the support rib 124, the elastic deformation of the first buffer member 127a can be used to release a part of the impact force F (that is, the mechanical energy of the protective plate 123 and the support rib 124 is converted into the internal energy of the first buffer member 127a), thereby further improving the protection of the electronic component 125.

[0101] In some embodiments, see Fig.16 As shown, Fig.16A schematic diagram of a cross section (parallel to the YZ plane) of another display module 12 at the first groove 1221 provided in an embodiment of the present application. The display module 12 may further include a second buffer 127b, and the support rib 124 is connected to the side wall of the second groove 1222 and the side wall of the first groove 1221 through the second buffer 127b.

[0102] The first buffer member 127a may be made of elastic materials such as colloid, foam double-sided tape, etc.

[0103] For example, see Fig.16 As shown, the second buffer member 127b is a colloid, and the second buffer member 127b completely covers the side walls of the second groove 1222 and the side walls of the second groove 1222. In the illustrated orientation, the upper surface of the protective plate 123 and the upper surface of the back plate 122 are in the same plane, and the side walls of the protective plate 123 and the side walls of the supporting ribs 124 are respectively completely fitted with the second buffer member 127b.

[0104] In this way, the second buffer member 127b can be used to bond and fix the support rib 124 in the first groove 1221 and the second groove 1222, thereby fixing the protective plate 123. In addition, the second buffer member 127b can be used to fill the gap between the support rib 124 and the side wall of the first groove 1221 and the side wall of the second groove 1222, so as to prevent the support rib 124 and the protective plate 123 from shifting.

[0105] In some embodiments, see Fig.17 As shown, Fig.17 The cross-section (parallel to the YZ plane) of another embodiment of the present application at the first groove 1221 of the display module 12 is shown in FIG. The display module 12 may further include a third buffer 127c, and the protective plate 123 is connected to the display area 1211 via the third buffer 127c.

[0106] The third buffer member 127c may be made of elastic materials such as colloid, foam double-sided tape, etc.

[0107] For example, see Fig.17 As shown, the third buffer member 127c is a double-sided foam tape. In the illustrated orientation, the third buffer member 127c completely covers the upper surface of the protective plate 123, and the upper surface of the third buffer member 127c is in the same plane as the upper surface of the back plate 122.

[0108] In this way, not only can the third buffer member 127c be used to bond the protective plate 123 to the display area 1211, but the third buffer member 127c can also be used to eliminate the step difference between the side of the protective plate 123 facing the display area 1211 and the side of the back panel 122 facing the display area 1211, thereby ensuring the flatness of the display area 1211 and the back panel 122 after bonding.

[0109] The following is a description of the installation process of the protective plate 123 and the supporting rib 124, taking the protective plate 123 and the supporting rib 124 as an integrally formed body, and the first buffer 127a, the second buffer 127b and the third buffer 127c as colloids as an example:

[0110] The first step, such as Fig.18 As shown, Fig.18 for Fig.17 Schematic diagram of the installation process of the middle protection plate 123 and the supporting ribs 124 Figure 1 , etching a first groove 1221 on the back plate 122;

[0111] The second step is, Fig.19 As shown, Fig.19 for Fig.17 Schematic diagram of the installation process of the middle protection plate 123 and the supporting ribs 124 Figure 2 According to the number of the supporting ribs 124 and their distribution on the protective plate 123 , a second groove 1222 corresponding to the supporting rib 124 is etched on the bottom surface of the first groove 1221 ;

[0112] The third step is Fig. 20 As shown, Fig. 20 for Fig.17 Schematic diagram of the installation process of the middle protection plate 123 and the supporting ribs 124 Figure 3 , in the illustrated orientation, a first buffer member 127a is coated on the bottom surface of the second groove 1222;

[0113] The fourth step is Fig.21 As shown, Fig.21 for Fig.17 Schematic diagram of the installation process of the middle protection plate 123 and the supporting ribs 124 Figure 4 , in the illustrated orientation, the second buffer member 127b is coated on the sidewall of the second groove 1222 and the sidewall of the first groove 1221;

[0114] Step 5: Fig. 22 As shown, Fig. 22 for Fig.17 Schematic diagram of the installation process of the middle protection plate 123 and the supporting ribs 124 Figure 5, insert the supporting rib 124 into the second groove 1222, and embed the protective plate 123 into the first groove 1221. In the illustrated position, the lower surface of the second region 1232 of the protective plate 123 is spaced a certain distance (i.e., a gap of 100) from the bottom surface of the first groove 1221;

[0115] Step 6. Please return to Fig.17 As shown, in the illustrated orientation, a third buffer member 127c is coated on the upper surface of the protection plate 123 to eliminate the step difference between the protection plate 123 and the back plate 122, and the installation is completed.

[0116] In the description of this specification, specific features, structures, materials or characteristics may be combined in an appropriate manner in any one or more embodiments or examples.
