Description

FIELD OF TECHNOLOGY

[0001] The present invention relates to the field of electronic device technology and, in particular, to a display module and an electronic device.

BACKGROUND OF THE INVENTION

[0002] Since the flexible display screen has the advantages of being light and thin, not fragile, foldable, rollable, etc., the flexible display screen is widely used in electronic products such as mobile phones. However, in a conventional mobile phone, the flexible display screen has a low hardness and the surface is easily broken. Therefore, the base sheet is located on the underside of the conventional flexible display screen, so that the flexible display screen is supported by the base sheet to solve the problem of breaking the surface of the flexible display screen. However, when the base sheet is thick, the base sheet restricts bending of the flexible display screen. Therefore, the mobile phone is not easy to fold. When the support sheet is thin, although the support sheet does not restrict bending of the flexible display screen, the excessively thin support sheet does not have sufficient structural strength and cannot support the flexible display screen well.

SUMMARY OF THE INVENTION

[0003] The present invention provides a display module and an electronic device that are easy to fold and have sufficient support strength.

[0004] According to the first aspect of the present invention provides a display module. The display module includes a display screen and a support member. The display screen includes a first non-flexible region, a flexible region, and a second non-flexible region that are connected in series. In other words, the bendable region is connected between the first non-flexible region and the second non-flexible region. The support member is attached to the side of the display screen that is not part of the display. The supporting element includes the first metal plate element, the first connecting plate element and the second metal plate element, which are connected in series. In other words, the first connecting plate element is connected between the first metal plate element and the second metal plate element. The first metal plate element faces the first inflexible area. The first connecting plate element faces the bendable area. The second metal plate element faces the second rigid area. The first connecting plate element is capable of bending.

[0005] In addition, the first connecting plate element includes a metal part and organic material parts. The metal part is provided with many grooves. The slots of the plurality of grooves are located on the first surface of the metal part. The organic material parts are located in a plurality of grooves and are rigidly connected to the metal part. The reference element further includes a first buffer element. The first buffer element is located between the first metal plate and the second metal plate. The first buffer element is laid on the first surface of the metal part and is rigidly connected to the parts made of organic material.

[0006] It can be understood that the hardness of the metal part is greater than the hardness of the organic material parts. It can be understood that the stiffness of the metal part is greater than the stiffness of the organic material parts. In this case, since the first connecting plate member has both a metal part and organic material parts, the overall rigidity and hardness of the first connecting plate member is moderate. When the electronic device is in the unfolded state, the first connecting plate member has sufficient rigidity and hardness to support the bendable area of the display screen to prevent the bendable area of the display screen from breaking, namely to ensure that the display screen has good surface flatness. When the electronic device is unfolded or folded, since the first connecting plate has good flexibility, the first connecting plate has less effect on the bending of the display screen. In other words, when the electronic device is folded or unfolded, the organic material parts can absorb the stress generated by psi bending.

[0007] In addition, the first base plate, the second base plate and the third base plate of the rotary apparatus are usually provided with a large number of grooves or through holes. A groove or through hole can serve as clearance for a component or be used to tighten a fastener. In the solution in which the first connecting plate element is provided with grooves and no part of organic material is located in the grooves, when the electronic device is in the unfolded state, the peripheral edges of the grooves or through holes on the first base plate, the second base plate and the third base plate of the rotating apparatus the first connecting plate element is easily squeezed out. Because the stress on the peripheral edges of the grooves of the first connecting plate member is concentrated, the peripheral edges of the grooves can extrude the optically transparent adhesive with a large extrusion force, and the optically transparent adhesive comes out. Therefore, a black spot, a bright line, or the like appears on the display screen. However, in this implementation, the organic material parts are located in the grooves of the metal part. Therefore, when the peripheral edges of the grooves or through holes on the first support plate, the second support plate, and the third support plate of the rotary apparatus extrude the first connecting plate member, the organic material portions can absorb the partial force of the extrusion to prevent excessive concentration of stress on the peripheral edges of the grooves, and specifically to prevent the optically transparent adhesive from protruding due to excessive extrusion. Therefore, a black spot, bright line, or the like is prevented from appearing on the display screen.

[0008] In addition, when the peripheral edges of the grooves or through holes on the first base plate, the second base plate and the third base plate extrude the first connecting plate element, the first connecting plate element transmits the extrusion force to the first buffer element. In this case, the first buffer member may also absorb a partial extrusion force to further prevent the appearance of a black spot, a bright line, or the like. on the display screen due to excessive extrusion,

[0009] In addition, when the peripheral edges of the grooves or through holes on the first support plate, the second support plate, and the third support plate extrude the first connecting plate member, if the first connecting plate member is broken and extrudes the display screen, the first buffer member can also prevent direct piercing. or extrusion by a broken first connecting plate element of the display screen. Therefore, the appearance of a black spot, a bright line, and the like is largely prevented. on the display screen.

[0010] In addition, the hardness and rigidity of the first metal plate member and the second metal plate member are large. In this case, when the electronic device is folded or unfolded, the first metal plate member has good hardness and rigidity to support the first display screen rigid area, and the second metal plate member has good hardness and rigidity to support the second display screen rigid area. Therefore, the destruction of the display screen is prevented, namely, good flatness of the surface of the display unit is ensured.

[0011] In addition, the first metal plate element, the first connecting plate element, the second metal plate element, and the first buffer element may form an integral component (support element). In this case, the method of mounting the support member as a single piece on the display screen is simple, namely, the assembly method of the display unit can be simplified.

[0012] In an implementation, the first surface faces the display screen. In other words, the slot of the groove faces the display screen. In addition, the first buffer element is fixed between the first connecting plate element and the display screen. The metal part further includes a second surface opposite the first surface, and the second surface is a complete and continuous surface. It can be understood that "complete and continuous surface" means that the second surface is flat and has no groove or through hole. In this case, the first connecting plate element has good integrity. When the peripheral edges of the grooves or through holes on the first base plate, the second base plate and the third base plate extrude the first connecting plate member, the first connecting plate member has sufficient strength to resist the extrusion force. Thus, the breakage of the first connecting plate member is prevented, and the protrusion in position due to the concentrated stress is prevented.

[0013] In an implementation, the first surface faces away from the display screen. In other words, the slot of the groove faces away from the display screen. In addition, the first buffer element is fixed on the surface of the first connecting plate element facing away from the display screen. The metal part further includes a second surface opposite the first surface. The second surface is a complete and continuous surface. In this case, the surface of the second connecting plate member, which is connected to the display screen, is a flat surface. When the peripheral edges of the grooves or through holes on the first support plate, the second support plate, and the third support plate extrude the first connection plate, the first connection plate has sufficient hardness and strength to withstand the extrusion force. Therefore, the first connection plate is prevented from piercing the display screen due to the first connection plate being broken.

[0014] In one embodiment, the metal portion further includes a second surface opposite the first surface. The reference element further includes a second buffer element. The second buffer element is laid on the second surface of the metal part. In other words, the first buffer element is located opposite the second buffer element. The first buffer element is fixed between the first connecting plate element and the display screen. The second buffer element is fixed on the surface of the first connecting plate element facing away from the display screen.

[0015] It can be understood that the first buffer element is located on the first surface of the first connecting plate element, and the second buffer element is located on the second surface of the first connecting plate element. Therefore, the flexibility of the support member facing the foldable area of the display screen is greatly improved. In this case, when the electronic device is unfolded or folded, the support member facing the bendable area can reduce the impact on the display screen during the bending process. In other words, when the electronic device is folded or unfolded, the first buffer element and the second buffer element can jointly absorb the stress generated by folding.

[0016] In addition, the first buffer element is located on the surface of the first connecting plate element close to the display screen, and the second buffer element is located on the surface of the first connecting plate element that faces away from the display screen. Therefore, when the electronic device is in the unfolded state, the peripheral edges of the grooves or through holes on the first base plate, the second base plate, and the third base plate of the rotating apparatus extrude the second buffer member. Thus, since the second buffer element has good flexibility, the second buffer element has sufficient flexibility to absorb the partial extrusion force. In this case, the stress at the peripheral edges of the grooves of the metal part is not concentrated, namely, the force with which the peripheral edges of the grooves of the metal part extrude the display screen is small. Therefore, the appearance of a black spot, a bright line, and the like is largely prevented. on the display screen. In addition, when the second buffer element transmits the partial extrusion force to the first buffer element via the first connecting plate element, the first buffer element can also absorb the partial extrusion force again. In this case, a large extrusion force acting on the display screen is further reduced. Therefore, the appearance of a black spot, a bright line, and the like is largely prevented. on the display screen.

[0017] In this implementation, in the thickness direction of the display module, the thickness from the bottom wall of the groove to the surface which is the metal part and which faces away from the display screen is in the range of 0.01 mm to 0.05 mm. Thus, the metal part can have good flexibility while the hardness and rigidity of the metal part are ensured. In other words, the hardness and rigidity of the first connecting plate element are moderate. Therefore, when the electronic device is in the unfolded state, the first connecting plate member has sufficient rigidity and hardness to support the bendable area of the display screen to prevent the bendable area of the display screen from breaking. When the electronic device is unfolded or folded, since the first connecting plate has good flexibility, the first connecting plate has less influence on the bending of the display screen.

[0018] In an embodiment, the first buffer element and the organic material parts are a single structure. In this case, the first buffer member and the organic material parts have good integrity, and the bonding strength between the first buffer member and the organic material parts is also good.

[0019] In an embodiment, the material of the organic material part includes P4U. The material of the organic material part further includes at least one of PU, TPU, TPE, TPR, TPV, and EVA.

[0020] It can be understood that when the electronic device is used normally (namely, when the electronic device is not subjected to collision or impact), P4U and PU can remain soft, namely, the elasticity index of the first connecting plate element is small. In this case, when the electronic device is unfolded or folded, the first connecting plate member has less effect on the folding or unfolding of the display screen, namely, P4U and PU can ensure that the first connecting plate member has a good folding property.

[0021] In addition, when the electronic device collides or hits, the P4U and the PU strongly collide or hit the metal part. In this case, the molecules in P4U and PU can instantly block each other, quickly shrink and harden. In this case, the elasticity index of the first connecting plate member is greatly increased in order to prevent the display screen from being deformed due to extrusion by the first connecting plate member. When the impact force or extrusion force acting on P4U and PU disappears, P4U and PU can quickly return to a soft state, namely, P4U and PU become soft from hard. Thus, it is guaranteed that the display module can continue to fold or unfold,

[0022] In one embodiment, the material of the organic material part includes a UV curable adhesive or a heat curable adhesive.

[0023] In this implementation, when the material of the organic material part includes a UV-curable adhesive or a heat-curable adhesive, the bonding strength between the organic material parts and the metal part is good, and the first connecting plate member formed by the part made of organic material, and the metal part has good integrity. In addition, the method of forming the organic material part is simple and convenient to operate.

[0024] In this implementation, the plurality of grooves form a plurality of first groove groups. A plurality of first groups of grooves are arranged in the first direction. Each first groove group includes a plurality of first grooves. A plurality of first grooves in the same first group of grooves are spaced in the second direction. A plurality of first grooves in two adjacent first groove groups alternate with each other. The second direction is the direction in which the first metal plate element faces the second metal plate element. The first direction is perpendicular to the second direction. For example, the first direction may be the width direction of the electronic device, namely the X-axis direction, and the second direction may be the length direction of the electronic device, namely the Y-axis direction.

[0025] In this implementation, the first groups of grooves are located on the metal part, so that the overall flexibility of the first connecting plate member can be improved to provide good flexibility of the display module. In addition, when the organic material portions are located in the first grooves, the overall flexibility of the first connecting plate member can be further improved. In this case, when the electronic device is folded or unfolded, the organic material portions disposed in the first groove groups can effectively absorb the bending force so that the folding and unfolding of the electronic device is not affected,

[0026] In this implementation, the first groove is a strip hole. The expansion direction of the first groove is parallel to the first direction. The width of the first groove in the second direction is 0.15 mm to 3 mm.

[0027] In this implementation, when the expansion direction of the first groove is parallel to the X-axis direction, and the width of the first groove in the Y-axis direction is in the range of 0.15 mm to 3 mm, the area that is the concave region formed by the metal part, and which is located in the XY plane is large. In this case, the area of the organic material part located in the first groove and located in the XY plane is also large. Therefore, when the electronic device is unfolded or folded, the organic material parts can absorb the stress generated during the bending process, namely, the display unit is prevented from easily bending due to excessive stress on the metal part. Therefore, the folding effect of the display unit is improved.

[0028] It is understood that, in order to provide greater hardness and rigidity to the support member, the grooves located on the support member are typically small in size. In this implementation, the organic material parts are located in the first grooves, and the organic material parts can improve the hardness and rigidity of the first connecting plate member to some extent. In this case, the size of the first groove located on the metal part is large (in particular, along the Y-axis, the maximum width of the first groove can be up to 3 millimeters). In addition, in the manufacturing process of the support member, the number of first grooves produced can be reduced to a great extent. Therefore, the manufacturing cost per support member is reduced.

[0029] In one embodiment, the support element further includes a second connecting plate element and a third metal plate element that face the display screen fold area, as well as a first metal plate element, a second connecting plate element, a third metal plate element, a first the connecting plate element and the second metal plate element are connected in series. The second connecting plate element is provided with grooves. The second connecting plate element includes a metal part and parts made of organic material. The reference element further includes a third buffer element. The third buffer element is located between the first metal plate element and the third metal plate element. The third buffer element is laid on the second connecting plate element.

[0030] In this implementation, since the second connecting plate element has both a metal part and organic material parts, the overall hardness and rigidity of the second connecting plate element are moderate. In addition, the second connecting plate element is stacked with the third buffer element. In this case, the flexibility of the partial area of the opera element can be improved by the interaction between the second connecting plate element and the third buffer element. In this case, the number of regions with good flexibility on the supporting element can be increased. Therefore, when the support member is attached to the display screen, the second connecting plate member can also be attached to the large bending angle area in the bendable area of the display screen to ensure that the bendable area of the display screen has a good bending effect.

[0031] According to a second aspect of the present invention, another display module is provided. The display module includes a display screen and a support member. The display screen includes a first non-flexible region, a flexible region, and a second non-flexible region that are connected in series. In other words, the flex region is connected between the first non-flexible region and the second non-flexible region. The support member is attached to the side of the display screen that is not part of the display. The supporting element includes the first metal plate element, the first connecting plate element and the second metal plate element, which are connected in series. In other words, the first connecting plate element is connected between the first metal plate element and the second metal plate element. The first metal plate element faces the first inflexible area. The first element of the connecting plate faces the bending area. The second metal plate element faces the second rigid area. The first connecting plate element is capable of bending.

[0032] The first connecting plate element includes a metal part and organic material parts. The metal part is provided with many grooves. The slots of the plurality of grooves are located on the first surface of the metal part. The organic material parts are located in a plurality of grooves and are rigidly connected to the metal part.

[0033] In the thickness direction of the display module, the height of the metal part is equal to the height of the first metal plate element and the height of the second metal plate element -

[0034] In the second direction, the width of the organic material part is in the range of 0.15 mm to 3 mm, and the width of the metal part between two adjacent organic material parts is in the range of 0.05 mm to 0.8 mm. The second direction is the direction in which the first metal plate element faces the second metal plate element.

[0035] It can be understood that the hardness of the metal part is greater than the hardness of the organic material parts. It is understood that the rigidity of the metal part is greater than the rigidity of the organic material parts. In this case, the first connecting plate member has both a metal part and organic material parts, the width of the organic material part is in the range of 0.15 mm to 3 mm, and the width of the metal part between two adjacent organic material parts is in the range from 0.05 mm to 0.8 mm. Therefore, the overall rigidity and hardness of the first element of the connection plate are moderate. In other words, the first connecting plate member has good hardness, rigidity and flexibility. When the electronic device is in the unfolded state, the first connecting plate member has sufficient rigidity and hardness to support the bendable area of the display screen, to prevent destruction or pitting in the bendable area of the display screen, namely to ensure that the display module has a good surface flatness. . When the electronic device is unfolded or folded, the first connecting plate member does not prevent the display screen from bending.

[0036] In addition, the organic material parts are located in the grooves of the metal part, so that the metal part and the organic material parts form a single structure, namely, the first connecting plate member has good integrity. In this case, the bonding strength between the metal part and the organic material parts is good. Therefore, when the peripheral edges of the grooves or through holes on the first support plate, the second support plate, and the third support plate extrude the first connecting plate member, since the bonding strength between the metal part and the organic material parts is good, the metal part cannot be easily broken to pierce or extrude the display screen.

[0037] In addition, when the peripheral edges of the grooves or grooves on the first support plate, the second support plate, and the third support plate of the rotary apparatus extrude the first connecting plate member, the organic material portions can absorb a partial extrusion force. In this case, the stress at the peripheral edges of the grooves is not excessively concentrated. Therefore, the optically transparent adhesive is prevented from protruding due to excessive extrusion, so that black spot, bright line, and the like are prevented. on the display screen.

[0038] In this embodiment, the material of the organic material part includes P4U. The material of the organic material part further includes at least one of PU, TPU, TPE, TPR, TPV, and EVA.

[0039] It can be understood that when the electronic device is used normally (namely, when the electronic device is not subjected to collision or impact), P4U and PU may remain soft, namely, the elasticity index of the first connecting plate element is small. In this case, when the electronic device is unfolded or folded, the first connecting plate member has less influence on the folding or unfolding of the display screen, namely, P4U and PU can ensure that the first connecting plate member has a good folding property.

[0040] In addition, when the electronic device collides or hits, the P4U and the PU strongly collide or hit the metal part. In this case, the molecules in P4U and PU can instantly block each other, quickly shrink and harden. In this case, the elasticity index of the first connecting plate element is significantly

is increased to prevent deformation of the display screen due to the extrusion of the first connecting plate member. When the impact force or extrusion force acting on P4U and PU disappears, P4U and PU can quickly return to a soft state, namely, P4U and PU become soft from hard. Thus, it is ensured that the display module can continue to bend or unfold.

[0041] In this implementation, in the thickness direction of the display module, the thickness from the bottom wall of the groove to the surface which is the metal part and which faces away from the display screen is in the range of 0.01 mm to 0.05 mm. Thus, the metal part can have good flexibility while the hardness and rigidity of the metal part are ensured. In other words, the hardness and rigidity of the first connecting plate member are moderate. Therefore, when the electronic device is in the unfolded state, the first connecting plate member has sufficient rigidity and hardness to support the bendable area of the display screen to prevent the bendable area of the display screen from breaking. When the electronic device is unfolded or folded, since the first connecting plate has good flexibility, the first connecting plate has less effect on the bending of the display screen.

[0042] According to a third aspect of the present invention, an electronic device is provided. The electronic device includes a housing and the above display module. The display module is mounted in the housing.

[0043] In this embodiment, the display module is easy to fold and has sufficient support strength. When the display module is applied to an electronic device, the electronic device is also easy to fold and also has sufficient support strength.

Description of Embodiments

[0060] FIG. 1 is a schematic structural representation of an electronic device in an unfolded state according to an embodiment of this application. The electronic device 100 may be a tablet computer, a mobile phone, a camera, a personal computer, a laptop, a vehicle-mounted device, or a wearable device. The electronic device 100 in the embodiment shown in FIG. 1 is described using a mobile phone as an example. For ease of description, as shown in FIG. 1, the width direction of the electronic device 100 is defined as the X-axis, the length direction of the electronic device 100 is defined as the Y-axis, and the thickness direction of the electronic device 100 is defined as the Z-axis.

[0061] With reference to FIG. 1, fig. 2 is a structural diagram of the electronic device shown in FIG. 1 when folded.

[0062] The electronic device 100 includes a first case 10, a second case 20, and a display module 30. The first case 10 and the second case 20 can be folded out relative to each other to be in an unfolded state. The first body 10 and the second body 20 can also be folded relative to each other to be in a folded state. In other words, the first body 10 and the second body 20 can be switched between the folded state and the unfolded state. In FIG. 1 shows that the electronic device 100 is in the unfolded state. In FIG. 2 shows that the electronic device 100 is in a collapsed state. It is clear that Fig. 1 shows that the direction in which the first body 10 faces the second body 20 is the positive direction of the Y-axis.

[0063] In addition, the display module 30 may be configured to display an image, video, or the like. The display module 30 includes a first part 34, a second part 35 and a third part 36. The second part 35 is connected between the first part 34 and the third part 36. The first part 34, the second part 35 and the third part 3 6 are located on one side of the first body 10 and the second body 20. In addition, the first part 34 is attached to the first body 10. The second part 35 is located between the first body 10 and the second body 20. The third part 3 6 is attached to the second body 20.

[0064] It is understood that when the electronic device 100 is in the unfolded state, the first part 34, the second part 35 and the third part 36 are approximately at an angle of 180° (slight deviation is allowed, for example, 165°, 177° or 185°). In this case, the display unit 30 has a continuous display area with a large area, namely, the display unit 30 can realize a large screen display, and the user experience is good. When the electronic device 100 is in the folded state, the display unit 30 is folded. In particular, the second part 35 is curved. The first part 34 and the third part 36 overlap each other along the Z axis. In this case, the unfolded area of the display unit 30 is small. This helps reduce the chance of damage to the display module 30.

[0065] In addition, in FIG. 2 shows that when the electronic device 100 is in the folded state, the display module 30 is located between the first case 10 and the second case 20, namely, the display module 30 can be folded inwards. In another embodiment, when the electronic device 100 is in a folded state, the first housing 10 and the second housing 20 may be located between the first part 34 and the third part 36, namely, the display module 30 can be folded outward. In particular, in this embodiment, it is not limited.

[0066] In addition, in FIG. 1 and FIG. 2 shows that the electronic device 100 can be folded once. In another embodiment, the electronic device 100 may be folded multiple times, namely, the display module 30 may include a plurality of parts. Folding can occur between any two parts.

[0067] It is understood that there are many relationships between the first body 10 and the second body 20, such as a swivel joint, a sliding joint, and a detachable latch joint. In this embodiment, the fact that the first body 10 is rotatably coupled to the second body 20 is used as an example for description. FIG. 3 is a partial exploded view of the electronic device 100 shown in FIG. 1 and FIG. 4 is a schematic representation of the installation of the rotation apparatus of the electronic device shown in FIG. 3 in the first case and the second case. The electronic device 100 further includes a rotation apparatus 40. The rotation apparatus 40 is connected to the first body 10 and the second body 20. By means of the rotation apparatus 40, the first body 10 and the second body 20 can be rotated relative to each other for folding or unfolding. The rotation apparatus 40 is located between the first body 10 and the second body 20, and the rotation apparatus 40 and the second part 35 of the display module 30 face each other.

[0068] The rotary apparatus 40 may include a first base plate 41, a second base plate 42, and a third base plate 43. The second base plate 42 is located between the first base plate 41 and the third base plate 43. In addition, the first base plate 41, the second the opera plate 42 and the third base plate 43 face the second part 35 of the display module 30.

[0069] In addition, one side of the second base plate 42 is movably connected to the first base plate 41. The other side of the second base plate 42 is also movably connected to the third base plate 43. In other words, the first base plate 41, the second base plate 42 and the third base plate plate 43 can move relative to each other. In addition, the side of the first base plate 41 facing away from the second base plate 42 is movably connected to the first body 10. The side of the third base plate 43 facing away from the second base plate 42 is movably connected to the second body 20. In this case, the first body 10 and the second body 20 can rotate relative to each other due to the interaction between the first base plate 41, the second base plate 42 and the third base plate 43 to be folded or unfolded.

[0070] It can be understood that when the electronic device 100 is unfolded, the first base plate 41, the second base plate 42, and the third base plate 43 jointly support the second portion 35 of the display module 30.

[0071] FIG. 5 is a schematic exploded view of the display module of the electronic device shown in FIG. 4. The display module 30 includes a display screen 31 and a support member 32. The display screen 31 is configured to display an image, video, and so on. The display screen 31 is a flexible display screen. For example, the flexible display screen 31 may be an organic light-emitting diocie (OLED) display screen, an active-matrix organic light-emitting diode (AMOLED} display screen, a mini mini organic light-emitting diode, micro light-emitting diode display screen, micro organic light-emitting diode display screen, or quantum dot light LED display screen emitting diodes, QLEDs).

[0072] Referring to FIG. 5 with reference to FIG. 4, the display screen 31 includes a first non-flexible region 3181, a folding region 3182, and a second non-flexible region 3183 that are connected in series. In other words, the foldable region 3182 is connected between the first non-flexible region 3181 and the second non-flexible region 3183. The first non-flexible region 3181 is part of the first portion 34 of the display module 30. The foldable region 3182 is part of the second portion 35. The second non-flexible region 3183 is part of the third portion 36.

[0073] Referring to FIG. 5 and FIG. 6, fig. 6 is a schematic representation of the display module of the electronic device shown in FIG. 4 when folded. When the electronic device 100 is in the unfolded state, the first non-flexible region 3181, the flexible region 3182, and the second non-flexible region 3183 are at approximately 180° (slight deviation is allowed, for example, 165°, 177°, or 185°). When the electronic device 100 is in the folded state, the foldable region 3182 is folded and the first non-flexible region 3181 faces the second non-flexible region 3183, FIG. 6 shows that the foldable region 3182 is approximately in the shape of a water drop. In another embodiment, the foldable region 3182 may be in the form of a half ring. In this application, it is not particularly limited,

[0074] FIG. 7a is a partial schematic cross-sectional view of an implementation of the display module of the electronic device shown in FIG. 4 along the line A-A. The display screen 31 may include a back film 311, a display panel 312, a polarizer 313 (polarizer, POL), and a protective cover 314 that are stacked in series. In other words, the display panel 312 is located between the back film 311 and the polarizer 313, and the protective cover 314 is attached to the side of the polarizer 313 that faces away from the display panel 312. The back film 311 may be configured to support the display panel 312. The display panel 312 is configured to display an image, video, or the like. The protective cover 314 is designed to protect the polarizer 313, the display panel 312, and the like.

[0075] In addition, the display screen 31 further comprises an optical transparent adhesive 315. The optically transparent adhesive 315 is attached between the polarizer 313 and the protective cover 314. The optically transparent adhesive 315 may allow the display light emitted by the display panel 312 to spread outside the electronic device 100, and can also enhance the flexibility of the display module 30.

[0076] In an implementation, the display screen 31 may be a touch screen. The display screen 31 may be configured to generate a touch signal based on a user's touch action. Specifically, when the user touches the camera software icon on the display screen 31, the display screen 31 can generate a touch signal based on the user's touch action and transmit the touch signal to a processor (not shown in the figure) of the electronic device 100. The processor receives the touch signal and opens the software. camera based on the touch signal. The processor may be installed in the first housing 10 (see Fig. 4) or in the second housing 20 (see Fig. 4).

[0077] The display panel 312 may have a touch function. In other words, the display panel 312 has a touch panel function. For example, the touch panel is embedded in the light emitting layer of the display panel 312 using on-cell technology. In another implementation, the display panel 312 may not have a touch function. In this case, the display screen 31 further includes a touch panel (not shown in the figure). The touchpad may be secured between the protective cover 314 and the polarizer 313 or may be positioned between the polarizer 313 and the display panel 312.

[0078] Referring again to Fig. 7a, the display screen 31 includes an outer surface 316 and an inner surface 317 that are opposed to each other. The outer surface 316 of the display screen 31 is the surface of the display screen 31 and faces the user when the user normally uses the electronic device 100, namely the display side of the display screen 31. The inner surface 317 of the display screen 31 is the surface of the display screen 31 and faces the inside of the electronic device 100 when the display unit 30 is installed in the first cabinet 10 and the second cabinet 20, namely, the non-display side of the display screen 31. The support member 32 of the display module 30 is fixed to the inner surface 317 of the display screen 31 . In one embodiment, the support member 32 may be fixed to the inner surface 317 of the display screen 31 with optical transparent adhesive (OCA), PVB film, foam tape, a material obtained by combining the above adhesive, and the like. In FIG. 7a shows that the optically transparent adhesive 39 is located between the support member 32 and the inner surface 317 of the display screen 31.

[0079] In this application, the support member 32 has a variety of arrangements. The following specifically describes four methods for positioning the support member 32 with reference to the respective accompanying drawings. It can be understood that in each embodiment, the structure of the support member 32 has good flexibility, strength, and hardness. In addition, the support member 32 also has good surface integrity and flatness,

[0080] In the first embodiment, again with reference to FIG. 7a, the support member 32 includes a first metal plate member 321, a first connecting plate member 322, a second metal plate member 323, and a first buffer member 324. The first connecting plate member 322 is connected between the first metal plate member 321 and the second metal plate member 323. It is understood that the direction in which the first metal plate member 321 faces the second metal plate member 323 is the length direction of the electronic device 100, namely the positive Y-axis direction. plate element 323 is the direction of the X axis.

[0081] The first buffer element 324 is located between the first metal plate element 321 and the second metal plate element 323, and the first buffer element 324 is fixed between the first connecting plate element 322 and the display screen 31. In FIG. 7a, the first metal plate member 321, the first connecting plate member 322, and the second metal plate member 323 are distinguished from each other using a dotted line.

[0082] In addition, the first buffer element 324 is located between the first metal plate element 321 and the second metal plate element 323, and the first buffer element 324 is stacked on the first connecting plate element 322. In this implementation, the first buffer element 324 is attached between the first connecting plate element 322 and a display screen 31. Specifically, the first buffer element 324 is attached to the foldable region 3182 with an optically clear adhesive 39.

[0083] In addition, as shown in FIG. 6, the first metal plate member 321 faces the first non-bending region 3181. The first metal plate member 321 is part of the first portion 34 of the display module 30. In particular, the first metal plate member 321 is attached to the first bendable region 3181, 3181 with an optically clear adhesive 39. .

[0084] Both the first connecting plate element 322 and the first buffer element 324 face the foldable region 3182. The first connecting plate element 322 and the first buffer element 324 are each part of the second part 35.

[0085] The second metal plate element 323 faces the second non-bending region 3183. The second metal plate element 323 is part of the third part 36. Both the first connecting plate element 322 and the first buffer element 324 can be bent. Specifically, the second metal plate member 323 is attached to the second rigid region 3183 with an optically clear adhesive 39.

[0086] Referring again to FIG. 6 and FIG. 7a, when the electronic device 100 is in the folded state, the first connecting plate member 322 and the first buffer member 324 are bent, and the first metal plate member 321 and the second metal plate member 323 face each other. In FIG. 6 shows that the support member 32 is approximately in the shape of a water drop. In another embodiment, the support element 32 may be in the form of a ring. In this application, this is not particularly limited. When the electronic device 100 is in the unfolded state, the first metal plate element 321, the first connecting plate element 322, the second metal plate element 323, and the first buffer element 324 are approximately at an angle of 180° (slight deviation is allowed, for example, 165°, 177° or 185°).

[0087] The materials of the first metal plate member 321 and the second metal plate member 323 are metals. For example, the first metal plate member 321 and the second metal plate member 323 may be made of, but are not limited to, copper, aluminum, beryllium copper, stainless steel, titanium alloy, and the like. In this case, the first metal plate member 321 and the second metal plate member 323 have good hardness and rigidity.

[0088] The material of the first buffer element 324 may be a polymeric material, but is not limited to. For example, the material of the first buffer element 324 may be another elastic material. In this case, the first buffer element 324 has good flexibility.

[0089] Referring to FIG. 7a, the first connecting plate member 322 includes a metal portion 3221 and organic material portions 3222. The metal part 3221 includes a first surface 3223 and a second surface 3224 that are opposed to each other. The first surface 3223 faces the display screen 31 . The metal part 3221 is provided with a plurality of grooves 3225. Each groove 3225 is recessed in the direction from the first surface 3223 to the second surface 3224. In other words, the slot of the groove 3225 is located on the first surface 3223 and faces the display screen 31. Parts 3222 of organic material are located in a plurality of grooves 3225 and are rigidly connected to the metal part 3221. In addition, the first buffer element 324 is stacked on the first surface 3223 of the metal part 3221. In other words, the first buffer element 324 is rigidly connected to the metal part 3221. In addition, , the first buffer element 324 is rigidly connected to the organic material portions 3222. It is understood that in the Y-axis direction, the number of organic material parts 3222 is not limited to the six shown in FIG. 7a.

[0090] The material of the metal part 3221 may be, among other things, copper, aluminum, beryllium copper, stainless steel, titanium alloy, and the like. Meanwhile, the metal part 3221 has good hardness and rigidity.

[0091] In addition, the material of the organic material portion 3222 may be, among other things, a polymeric material. In this case, the organic material portion 3222 has good flexibility.

[0092] In addition, in the Z direction, the height of the metal part 3221 is H1, the height of the first metal plate member 321 is H2, and the height of the second metal plate member 323 is H3. In this implementation, H1 is less than H2 and H1 is less than H3. Of course, in another implementation H1 could be equal to H2 and H1 could be equal to H3.

[0093] It can be understood that the hardness of the metal part 3221 is greater than the hardness of the organic material parts 3222. It is clear that the rigidity of the metal part 3221 is greater than the rigidity of the organic material parts 3222. In this case, since the first connecting plate member 322 has both a metal part 3221 and organic material parts 3222, the overall rigidity and hardness of the first connecting plate member 322 are moderate. When the electronic device 100 is in the unfolded state, the first connecting plate member 322 has sufficient rigidity and hardness to support the bendable area 3182 of the display screen 31 to prevent the bending area 3182 of the display screen 31 from breaking, namely, to ensure that the display screen 31 has good surface flatness. When the electronic device 100 is unfolded or folded, since the first connection plate 322 has good flexibility, the first connection plate 322 is less affected by the bending of the display screen 31. In other words, when the electronic device 100 is folded or unfolded, the organic material portions 3222 can absorb stress generated by bending.

[0094] In addition, the first base plate 41, the second base plate 42, and the third base plate 43 of the rotation apparatus 40 are usually provided with a large number of grooves or through holes. A groove or through hole can serve as clearance for a component or be used to tighten a fastener. In the solution in which the first connecting plate member 322 is provided with grooves 3225 and no organic material part 3222 is located in the grooves 3225, when the electronic device 100 is in the unfolded state, the peripheral edges of the grooves or through holes on the first base plate 41, the second base plate 42 and the third base plate 4 3 of the rotary apparatus 40, the first connecting plate member 322 is easily extruded. adhesive 39 protrudes. Therefore, a black spot, a bright line, or the like appears on the display screen 31 . However, in this implementation, the organic material portions 3222 are disposed in the grooves 3225 of the metal portion 3221. Therefore, when the peripheral edges of the grooves or through holes on the first base plate 41, the second base plate 42, and the third base plate 43 of the rotation apparatus 40 extrude the first connecting plate member 322 , the organic material portions 3222 can absorb a partial extrusion force to prevent excessive stress concentration at the peripheral edges of the grooves 3225, namely, to prevent the optically clear adhesive 39 from protruding due to excessive extrusion. Therefore, a black spot, a bright line, or the like is prevented. on the display screen 31.

[0095] In addition, when the peripheral edges of the grooves or through holes on the first support plate 41, the second support plate 42, and the third support plate 43 extrude the first connecting plate member 322, the first connecting plate member 322 transmits the extrusion force to the first buffer member 324. B In this case, the first buffer member 324 may also absorb a partial extrusion force to further prevent the appearance of a black spot, bright line, or the like. on the display screen 31 due to excessive extrusion.

[0096] In addition, when the peripheral edges of the grooves or through holes on the first base plate 41, the second base plate 42 and the third base plate 43 extrude the first connecting plate member 322, if the first connecting plate member 322 is broken and extrudes the display screen 31, the first buffer the element 324 can also prevent the broken first connecting plate element 322 of the display screen 31 from being directly pierced or extruded. Therefore, the appearance of a black spot, a bright line, and the like is largely prevented. on the display screen 31.

[0097] In addition, the hardness and rigidity of the first metal plate member 321 and the second metal plate member 323 are large. In this case, when the electronic device 100 is folded or unfolded, the first metal plate member 321 has good hardness and rigidity to support the first rigid area 3181 of the display screen 31, and the second metal plate member 323 has good hardness and rigidity to support the second rigid area 3183 of the screen. 31 displays. In this way, the destruction of the display screen 31 is prevented, namely, a good flatness of the surface of the display module 30 is ensured.

[0098] In addition, the first metal plate member 321, the first connecting plate member 322, the second metal plate member 323, and the first cushion member 324 may form an integral component (support member 32). on the display screen 31 is simple, namely, the assembly method of the display unit 30 can be simplified.

[0099] In an implementation, the first metal plate member 321, the metal part 3221, and the second metal plate member 323 form a single structure. In other words, the first metal plate member 321, the metal part 3221, and the second metal plate member 323 form a single structure. In this case, the connection strength between the first metal plate member 321, the metal part 3221, and the second metal plate member 323 is better. In addition, there are fewer steps to form the first metal plate member 321, the metal part 3221, and the second metal plate member 323. This can reduce the manufacturing cost of the support member 32.

[00100] Specifically, the first metal plate member 321, the metal portion 3221 of the first connecting plate member 322, and the second metal plate member 323, which are connected in series, are formed on the solid plate member by CNC machining. In another embodiment, the first metal plate member 321, the metal part 3221, and the second metal plate member 323, which are connected in series, may be formed in a manner such as injection molding or chemical corrosion.

[00101] In another embodiment, the first metal plate member 321, the metal part 3221, and the second metal plate member 323 may be formed by welding or connected by a latch.

[00102] In an implementation, the materials of the first metal plate member 321, the metal portion 3221, and the second metal plate member 323 are the same. In this case, the support member 32 has fewer types of materials. This can shorten the material preparation step of the support member 32 and reduce the manufacturing cost of the support member 42.

[00103] In an embodiment, the first metal plate member 321, the metal portion 3221, and the second metal plate member 323 are formed using a single step. It is understood that one-step molding includes techniques such as extrusion molding, injection molding, compression molding, and

calendering. Thus, the support member 32 has fewer manufacturing steps. This can reduce the manufacturing cost of the support member 32.

[00104] In an implementation, the second surface 3224 is a complete and continuous surface. It can be understood that "complete and continuous surface" means that the second surface 3224 is flat and has no groove or through hole. In this case, the second connecting plate element has good integrity. When the peripheral edges of the grooves or through holes on the first base plate 41, the second base plate 42, and the third base plate extrude the first connecting plate member 322, the first connecting plate member 322 has sufficient strength to withstand the extrusion force. Thus, breakage of the first connection plate 322 is prevented, and protrusion in position due to concentrated stress is prevented.

[00105] Referring to FIG. 7a, again in the Z direction, namely in the thickness direction of the display module 30, the height H1 of the metal part 3221 is in the range of 0.015 mm to 0.3 mm. Thus, the first connecting plate member 322 can have good flexibility while the hardness and rigidity of the first connecting plate member 322 is ensured. In other words, the hardness and rigidity of the first connecting plate member 322 are moderate.

[00106] Referring to FIG. 7a, in the Z direction, the height H2 of the first metal plate member 321 and the height H3 of the second metal plate member 323 are at. range from 0.1 mm to 0.5 mm. Thus, the first metal plate member 321 and the second metal plate member 323 have sufficient hardness and rigidity. Thus, when the electronic device 100 is unfolded or folded, the first metal plate member 321 and the second metal plate member 323 can support the display screen 31 effectively. In addition, the first metal plate member 321 and the second metal plate member 323 are thin. Therefore, the first metal plate member 321 and the second metal plate member 323 do not increase the thickness of the display module 30 to a great extent.

[00107] FIG. 7b is a schematic enlargement of the electronic device shown in FIG. 7a at position B. In the Z direction, the height H5 of the first buffer element 324 is in the range of 0.01 mm to 0.2 mm. Thus, when the peripheral edges of the grooves or through holes on the first support plate 41, the second support plate 42, and the third support plate 43 extrude the first connecting plate member 322, the first connecting plate member 322 transmits the extrusion force to the first buffer member 324. In this case, the first buffer member 324 has sufficient flexibility to absorb the extrusion force to further prevent black spot, bright line, and the like. on the display screen 31 due to excessive extrusion.

[00108] In addition, when the peripheral edges of the grooves or through holes on the first base plate 41, the second base plate 42 and the third base plate 43 extrude the first connecting plate member 322, if the first connecting plate member 322 is broken and extrudes the display screen 31, the first buffer the element 324 has a sufficient thickness to prevent direct piercing or extrusion of the broken first connecting plate element 322 of the display screen 31 . Therefore, the appearance of a black spot, a bright line, and the like is largely prevented. on the display screen 31.

[00109] Referring to FIG. 7b, the groove 3225 includes a side wall 3229 and a bottom wall 3228. The bottom wall 3228 is connected to the side wall 3229. In the Z direction, the thickness H6 from the bottom wall 3228 of the groove 3225 to the surface consisting of the metal part 3221 and facing away from the screen 31 display, ranges from 0.01 mm to 0.05 mm. In other words, the thickness H6 from the bottom wall 3228 of the groove 3225 to the second surface 3224 is 0.01 mm to 0.05 mm. Thus, the metal part 3221 can have good flexibility while the hardness and rigidity of the metal part 3221 are ensured. In other words, the hardness and rigidity of the first connecting plate member 322 are moderate. Therefore, when the electronic device 100 is in the unfolded state, the first connecting plate member 322 has sufficient rigidity and hardness to support the bendable area 3182 of the display screen 31 to prevent the bending area 3182 of the display screen 31 from breaking. When the electronic device 100 is unfolded or folded, since the first connection plate member 322 has good flexibility, the first connection plate member 322 is less affected by the bending of the display screen 31.

[00110] FIG. 8 is a partial schematic structural view of the first connecting plate element of the display module shown in FIG. 7a. The metal portion 3221 is provided with a plurality of first groove groups M and two second groove groups N. Two second groups N of grooves are respectively located on two sides of the plurality of first groups M of grooves. In FIG. 8 shows one second group N of grooves in the positive X-axis direction. It will be understood that one second group N of grooves is respectively also located in the negative X-axis direction. Of course, in another embodiment, the metal part 3221 may not have two second groups N of grooves.

[00111] A plurality of first groove groups M are arranged in the X-axis direction. It is understood that in the X-axis direction, each two first groove groups M can be arranged parallel to each other, but a slight deviation is allowed, for example, 155°, 166° or 177°. In addition, each first groove group M includes a plurality of first grooves 3226. A plurality of first grooves 3226 are spaced in the Y-axis direction. slight deviation, such as 155°, 166° or 177°. In addition, in FIG. 8 shows that a plurality of first grooves 3226 in two adjacent first groove groups M alternate with each other. In other words, there is an overlapping portion between the first grooves 322 6 in two adjacent first groove groups M. In another embodiment, the plurality of first grooves 3226 in the first groove groups M may be spaced apart from each other.

[00112] Every second groove group N includes a plurality of second grooves 3227. A plurality of second grooves 3227 in the same second groove group N are spaced in the Y-axis direction. It is understood that in the Y-axis direction, every two second grooves 3227 may parallel to each other, but a slight deviation is allowed, for example, 155°, 166° or 177°. In addition, a plurality of second grooves 3227 in the same second groove group N extend through the side surface of the metal piece 3221. In FIG. 8 shows that a plurality of second grooves 3227 in the second group of grooves N in the positive direction of the X axis extend through the side surface of the metal piece 3221.

[00113] In addition, in FIG. 8 shows that at least a portion of each second groove 3227 is located between the first two grooves 3226. In other words, there is an overlap between the second groove 3227 and the first groove 3226. Alternatively, each second groove 3227 may be spaced apart from the first groove 3226.

[00114] in this implementation, the first group M of grooves and the two second groups N of grooves are located on the metal part 3221, so that the overall flexibility of the first connecting plate element 322 can be improved to ensure good flexibility of the display module 30. In addition, when the parts 3222 of organic material are located in the first grooves 3226 and the second grooves 3227, the overall flexibility of the first connecting plate element 322 can be further improved. In this case, when the electronic device 100 is folded or unfolded, the organic material portions 3222 can effectively absorb the bending force so that the folding and unfolding of the electronic device 100 is not affected.

[00115] In addition, a plurality of second grooves 3227 extend through the side surface of the first connection plate member 322 to avoid partial stress concentration in the side portion of the first connection plate member 322. In this case, when the electronic device 100 is unfolded or folded, the second grooves 3227 may to absorb the stress generated during the bending process of the display module 30, namely, the display module 30 is prevented from bending easily due to too much stress on the side surface of the first connecting plate member 322.

[00116] With reference to FIG. 8, fig. 9a is a partial structural view of the first connecting plate element shown in FIG. 8, which does not contain a portion of organic material. The first groove 3226 is a strip hole. The extension direction of the first groove 322 6 is parallel to the X-axis direction. The width d1 of the first groove 3226 in the Y-axis direction is 0.15 mm to 3 mm. For example, d1 is equal to 0.15 mm, 0.2 6 mm, 1 mm, 2 mm, or 3 mm. In another implementation, the direction of continuation of the first groove 3226 may be parallel to the direction of the Y axis.

[00117] In this embodiment, when the expansion direction of the first groove 3226 is parallel to the X-axis direction, and the oil width of the first groove 3226 in the Y-axis direction is in the range of 0.15 mm to 3 mm, an area that is a hollow region formed metal part 3221, and which is located in the X-Y plane, is large. In this case, the area of the organic material part 3222 located in the first groove 3226 and located in the X-Y plane is also large. Thus, when the electronic device 100 is unfolded or folded, the organic material portions 3222 can absorb the stress generated during the folding process, namely, prevent the display module 30 from easily bending due to excessive stress on the metal part 3221. Therefore, the folding effect of the display module 30 is improving.

[00118] It is understood that, in order to provide greater hardness and rigidity to the support member 32, the grooves located on the support member are typically small in size. In this embodiment, the organic material portions 3222 are located in the first grooves 3226, and the organic material portions 3222 can improve the hardness and rigidity of the first connector plate member 322 to some extent. In this case, the size of the first groove 3226 located on the metal part 3221 is large (in particular, along the Y-axis, the maximum value of the width d1 of the first groove 3226 can be up to 3 millimeters). In addition, during the manufacturing process of the support member 32, the number of first grooves 3226 produced can be significantly reduced. Therefore, the manufacturing cost of the support member 32 is reduced.

[00119] In one embodiment, the second groove 3227 is a strip hole. The expansion direction of the second groove 3227 is parallel to the X direction. The width d2 of the second groove 3227 in the Y direction is 0.15 mm to 3 mm. For example, d2 is 0.15 mm, 0.26 mm, 1 mm, 2 mm, or 3 mm. In another embodiment, the expansion direction of the second groove 3227 may be parallel to the Y direction.

[00120] In this implementation, when the expansion direction of the second groove 3227 is parallel to the X-axis direction, and the width d2 of the second groove 3227 along the Y-axis is in the range of 0.15 mm to 3 mm, the area which is the hollow area formed by the metal part 3221 , and which is located in the X-Y plane, is large. In this case, the area of the organic material part 3222 located in the second groove 3227 and located in the X-Y plane is also large. Therefore, when the electronic device 100 is unfolded or folded, the organic material portions 3222 can absorb the stress generated during the folding process of the display module 30, namely, prevent the display module 30 from easily bending due to excessive stress on the metal part 3221. Therefore, the effect folding of the display module 30 is improved.

[00121] It is understood that, in order to provide greater hardness and rigidity to the support member 32, the grooves 3225 located on the support member are typically small in size. In this implementation, the size of the second groove 3227 located on the metal part 3221 may be large (in particular, the maximum value of the width of the second groove 3227 along the Y-axis may be up to 3 millimeters). In this case, during the manufacturing process of the support member 32, the number of second grooves 3227 produced can be reduced to a great extent. Therefore, the manufacturing cost of the support member 32 is reduced.

[00122] In the Y-axis implementation, the distance d3 between two adjacent first grooves 3226 in the same first groove group M is in the range of 0.05 mm to 0.8 mm. For example, d3 is equal to 0.05 mm, 0.1 mm, 0.2 mm, 0.5 mm, 0.6 mm, or 0.8 mm.

[00123] It is understood that in order to provide great flexibility of the support member 32, the distance between two adjacent grooves 3225 on the support member 32 is usually small, namely the size of the metal portion 3221 between the grooves 3225 is small. In this embodiment, the distance d3 between the two first grooves 322 6 may be large (for example, along the Y-axis, the maximum value of the distance d3 between the two first grooves 3226 may be up to 0.8 millimeters). In this case, the organic material portions 3222 are arranged in the grooves 3225. Therefore, the support member 32 can be guaranteed to have good hardness and rigidity, and the flexibility of the support member 32 can be improved to some extent.

[00124] FIG. 9b is a partial schematic structural representation of another embodiment of the first connecting plate element shown in FIG. 8, which does not contain part of the organic material. The plurality of first grooves 3226 and the plurality of second grooves 3227 communicate with each other. In this case, the plurality of first grooves 3226 and the plurality of second grooves 3227 form a mesh structure. In this case, the first connecting plate element 322 has more flexibility, namely, the first connecting plate element 322 has less influence on the bending of the display screen 31.

[00125] It can be understood that the organic material portion 3222 located in the groove 3225 has a variety of forming methods.

[00126] In the first embodiment, as shown in FIG. 7a in FIG. 9a, the organic material parts 3222 are bonded to the metal part 3221 by injection molding. In other words, the organic material parts 3222 are formed on the metal part 3221 using an injection molding technique and bonded to the metal part 3221.

[00127] Specifically, the resin material is injected into the groove 3225 of the metal piece 3221 using an injection molding technique. Upon cooling and curing, the polymeric material forms the organic material portion 3222.

[00128] It can be understood that the organic material parts 3222 are connected to the metal part 3221 by injection molding, so that the strength of the connection between the organic material parts 3222 and the metal part 3221 can be improved, and the first connecting plate member 322 is formed of the part 3222 from organic material, and the metal part 3221 has good integrity.

[00129] In one embodiment, the material of the organic material portion 3222 includes at least one material of polyurethane (polyurethane, PU), thermoplastic polyurethane (thermoplastic polyurethane, TPU), thermoplastic' elastomer (thermoplastic elastomer, TPE), thermoplastic rubber material (thermo-plastic-rubber material, TPR), thermoplastic vulcanizate (thermoplastic vulcanizate, TPV) and ethylene-vinyl acetate copolymer (EVA). The organic material portion 3222 further includes P4U. In this embodiment, the organic material portion 3222 includes P4U and PU. In another implementation, the organic material portion 3222 may include P4U, TPR, and TPV.

[00130] It should be understood that when the electronic device 100 is used normally (namely, the electronic device 100 is not subjected to collision or shock), P4U and PU can remain soft, namely, the elasticity index of the first connecting plate member 322 is small. In this case, when the electronic device is unfolded or folded, the first connecting plate member 322 has less influence on the folding or unfolding of the display screen 31, namely, P4U and PU can provide a good folding property of the first connecting plate member 322.

[00131] In addition, when the electronic device 100 is collided or hit, the P4U and PU are strongly collided or hit by the metal part 3221. In this case, the molecules in the P4U and the PU can momentarily block each other, quickly shrink and solidify. In this case, the elasticity index of the first connecting plate member 322 is greatly increased to prevent the display screen 31 from being deformed due to extrusion by the first connecting plate member 322. into a soft state, namely, P4U and PU from hard to soft. Therefore, it is guaranteed that the display module 30 can continue to be bent or unfolded.

[00132] In one embodiment, the implementation of the first buffer element 324 and parts 3222 of organic material are a single structure. In this case, the first buffer member 324 and the organic material portions 3222 have good integrity, and the bonding strength between the first buffer member 324 and the organic material portions 3222 is also good.

[00133] In one embodiment, the materials of the first buffer element 324 and the organic material portion 3222 are the same. In other words, the material of the first buffer element 324 includes P4U. The material of the first buffer element 324 further includes at least one of PU, TPU, TPE, TPR, TPV, and EVA. In this case, the support member 32 has fewer types of materials. This can shorten the material preparation step of the support member 32 and reduce the manufacturing cost of the support member 42.

[00134] In one embodiment, the first buffer element 324 and the organic material portions 3222 are formed in one step. Specifically, when the uncured resin material is injected into the groove 3225, the uncured resin material overflows through the groove 3225 and solidifies between the first metal plate 321 and the second metal plate 323 to form the first buffer member 324.

[00135] In this implementation, the first buffer element 324 and the organic material portions 3222 are formed in one step. Thus, the support member 32 has fewer manufacturing steps. This can reduce the manufacturing cost of the support member 32.

[00136] In a second embodiment, the organic material portions 3222 are bonded to the metal portion 3221 through UV curing and thermal curing. Specifically, the organic material portion 3222 includes a UV curable adhesive or a heat curable adhesive.

[00137] In an embodiment, the organic material portion 3222 includes a UV curable adhesive. In particular, the groove 3225 is filled with an uncured UV-curable adhesive. The uncured, ultraviolet cured adhesive is irradiated with ultraviolet light. When exposed to UV light, the uncured UV cured adhesive cures to form the organic material portion 3222.

[00138] In this embodiment, the organic material parts 3222 are bonded to the metal part 3221 by ultraviolet curing, so that the bonding strength between the organic material parts 3222 and the metal part 3221 can be improved, and the first connecting plate member 322 formed by the metal parts 3222 organic material, and the metal part 3221 have good integrity. In addition, the method of forming part 3222 from organic material is simple and easy to operate.

[00139] In one embodiment, the first buffer element 324 and parts 3222 of organic material are a single structure. In this case, the first buffer member 324 and the organic material portions 3222 have good integrity, and the bonding strength between the first buffer member 324 and the organic material portions 3222 is also good.

[00140] In one embodiment, the materials of the first buffer element 324 and the organic material portion 3222 are the same. In other words, the first buffer element 32 4 includes a UV curable adhesive. In this case, the step of preparing the material of the support member 32 can be shortened, and the manufacturing cost of the operculum 42 can be reduced.

[00141] In one embodiment, the first buffer element 324 and the organic material portions 3222 are formed in one step. Specifically, when the uncured UV-cured adhesive is filled into the groove 3225, the uncured UV-cured adhesive overflows through the groove 3225. In this case, the uncured UV adhesive in the groove 3225 and the uncured UV adhesive between the first metal plate member 321 and the second metal plate element 323 are simultaneously irradiated with ultraviolet light. The uncured UV-cured adhesive in groove 3225 cures to form organic material portion 3222. The uncured, UV curable adhesive between the first metal plate member 321 and the second metal plate member 323 cures to form the first buffer member 324.

[00142] In this implementation, the first buffer element 324 and the organic material portions 3222 are formed in one step. Thus, the support member 32 has fewer manufacturing steps. This can reduce the manufacturing cost of the support member 32.

[00143] In an embodiment, the organic material portion 3222 includes a heat-set adhesive.

[00144] In particular, the groove 3225 is filled with a non-cured thermoset adhesive. The thermoset adhesive may be, but is not limited to, an adhesive. In this case, the adhesive can naturally cure at normal temperature to form part 3222 of organic material.

[00145] In one embodiment, the implementation of the first buffer element 324 and parts 3222 of organic material are a single structure. In this case, the first buffer member 324 and the organic material portions 3222 have good integrity, and the bonding strength between the first buffer member 324 and the organic material portions 3222 is also good.

[00146] In one embodiment, the materials of the first buffer element 324 and the organic material portion 3222 are the same. In other words, the first buffer element 324 includes a thermally set adhesive. In this case, the support member 32 has fewer types of materials. This can shorten the material preparation step of the support member 32 and reduce the manufacturing cost of the support member 42.

[00147] In one embodiment, the first buffer element 324 and the organic material portions 3222 are formed in one step.

[00148] In particular, the uncured thermoset adhesive is filled in the groove 3225, and the uncured thermoset adhesive overflows through the groove 3225 and flows between the first metal plate member 321 and the second metal plate member 323. The uncured thermoset adhesive in the groove 3225 is cured to form an organic part 3222. material. The uncured thermoset adhesive between the first metal plate member 321 and the second metal plate member 323 cures to form the first buffer member 324.

[00149] In this embodiment, the first buffer element 324 and the organic material portions 3222 are formed in one step. Thus, the support member 32 has fewer manufacturing steps. This can reduce the manufacturing cost of the support member 32.

[00150] The foregoing specifically describes a method for forming part 3222 from organic material. The following further specifically describes the support member 32 having a different design.

[00151] FIG. 10 is a partial schematic cross-sectional view of another embodiment of the display module of the electronic device shown in FIG. 4 in line A-A. The support member 32 further includes a third buffer member 3256, as well as a third metal plate member 3251 and a second link plate member 3252, which face the foldable area 3182 of the display screen 31. In addition, the first metal plate member 321, the second connection plate member 3252, the third metal plate member 3251, the first connection plate member 322, and the second metal plate member 323 are connected in series.

[00152] In the Z direction, the height H4 of the second connecting plate element 3252 is less than the height H2 of the first metal plate element 321 and the height H3 of the second metal plate element 323. In another embodiment, in the Z direction, the height H4 of the second connecting plate element 3252 may be equal to the height H2 of the first of the metal plate member 321 and height H3 of the second metal plate member 323. In addition, the second connecting plate member 3252 is provided with grooves 3225. The second connecting plate member 3252 includes a metal portion 3221 and organic material portions 3222 disposed in the grooves 3225. Parts 3222 of organic material are rigidly connected to the metal part 3221.

[00153] In addition, the third buffer element 3256 is located between the first metal plate element 321 and the third metal plate element 3251 and is stacked on the second connecting plate element 3252. In one implementation, the third buffer element 3256 is attached between the second connecting plate element 3252 and the bendable area 3182 screens 31 displays.

[00154] It should be understood that the method of locating the groove 3225 in this embodiment refers to the method of locating the groove 3225 of the first connecting plate element 322 in previous implementations. The details are not repeated here. With respect to the material and arrangement methods of the metal portion 3221 in this embodiment, the material and arrangement method of the metal portion 3221 of the first connecting plate member 322 in the previous embodiments is applicable. The details are not re-described here. With respect to the material and arrangement method of the organic material portion 3222 in this embodiment, the material and arrangement method of the organic material portion 3222 of the first connecting plate member 322 in the previous embodiments is applicable. The details are not repeated here.

[00155] In this embodiment, since the second connecting plate member 3252 has both a metal part 3221 and organic material parts 3222, the overall hardness and rigidity of the second connecting plate member 3252 is moderate. In addition, the second connecting plate element 3252 is stacked with the third buffer element 3256. In this case, the flexibility of a partial area of the support element 32 can be improved due to the interaction between the second connecting plate element 3252 and the third buffer element 3256. In this case, the number of areas with good flexibility on the support element 32 can be increased. Therefore, when the support member 32 is attached to the display screen 31, the second connecting plate member 3252 can also be attached to a large bending angle area in the bending area 3182 of the display screen 31 to ensure that the bending area of the display screen 31 has a good bending effect.

[00156] In another embodiment, the opening of the groove 3225 may face away from the display screen 31. In other words, the third buffer element 3256 is fixed on the surface of the second connecting plate element 3252, which is removed from the display screen 31. Alternatively, in another embodiment, the support element 32 may not include the third buffer element 3256.

[00157] In another embodiment, support member 32 may further include a fourth metal plate member, a fifth metal plate member, ... and S ^th metal plate member. S is an integer greater than or equal to 6. In addition, the support member 32 may further include a third plate connection, a fourth plate connection, . . . and a P ^th plate connection. P is an integer greater than or equal to 5. The connection plate P ^th is connected between two metal plate elements. The connecting plate element P ^th is provided with grooves 3225. The connecting plate element P ^th includes a metal part 3221 and organic material parts 3222 located in grooves 3225. The organic material parts 3222 are rigidly connected to the metal part 3221.

[00158] The foregoing specifically describes the first embodiment (first surface 3223 facing away from the display screen 31) of the display module 30. Next, the second embodiment (first surface 3223 facing away from the display screen 31) is specifically described using the corresponding accompanying drawings.

[00159] In the second embodiment, the same content as in the first embodiment is not described again. In other words, most of the contents of the first embodiment can be directly applied to the second embodiment.

[00160] FIG. 11 is a partial schematic cross-sectional view of another embodiment of the display module of the electronic device shown in FIG. 4 along the line A-A. The first surface 3223 faces away from the display screen 31 . In other words, the slot of the groove 3225 faces away from the display screen 31 . In this case, the first buffer member 324 is attached to the surface that is the first connecting plate member 322 and faces away from the display screen 31 . With respect to the material and method of forming the first buffer member 324 in this embodiment, the material and method of forming the first buffer member 324 in the first embodiment is applicable. The details are not repeated here.

[00161] It can be understood that after the interaction of the first connecting plate element 322 with the first buffer element 324, the overall rigidity and hardness of the support element 32 facing the bending region 3182 are moderate. In this case, when the electronic device 100 is in the unfolded state, the support member 32 has sufficient rigidity and hardness to support the bendable area of the display screen 31 to prevent the bendable area of the display screen 31 from breaking, namely, to ensure that the display module 30 had good surface flatness,

[00162] In addition, the first buffer member 32 4 is located on the surface of the first connecting plate member 322 facing away from the display screen 31 to further increase the flexibility of the support member 32 facing the foldable area 3182 of the display screen 31. When the electronic device 100 is unfolded or folded, the support member 32 facing the foldable region 3182 has good flexibility so that the display screen 31 is prevented from bending due to the large hardness and rigidity of the support member 32. In other words, when the electronic device 100 is folded or unfolded, the first buffer member 324 can absorb the stress generated by bending.

[00163] In addition, the first buffer element 324 is located on the surface of the first connecting plate element 322 facing away from the display screen 31. Therefore, when the electronic device 100 is in the unfolded state, the peripheral edges of the grooves or through holes on the first base plate 41, the second base plate 42, and the third base plate 43 of the rotation apparatus 40 extrude the first buffer member 324. Thus, the first buffer member 324 can absorb the partial extrusion force. In this case, the stress on the peripheral edges of the grooves 3225 of the metal part 3221 is not concentrated, namely, the force with which the peripheral edges of the grooves 3225 of the metal part 3221 extrude the display screen 31 is small. Therefore, the appearance of a black spot, a bright line, and the like is largely prevented. on the display screen 31.

[00164] In an embodiment, the second surface 3224 is a complete and continuous surface. In this case, the surface of the second connecting plate member 43, which is connected to the display screen 31, is a flat surface. When the peripheral edges of the grooves or through holes on the first base plate 41, the second base plate 42, and the third base plate 43 extrude the first connecting plate member 322, the first connecting plate member 322 has sufficient hardness and strength to withstand the extrusion force. Therefore, the first connecting plate member 322 cannot pierce the display screen 31 because the first connecting plate member 322 is broken.

[00165] In the third embodiment, the same content as in the first embodiment is not described again. In other words, most of the contents of the first embodiment can be directly applied to the third embodiment.

[00166] FIG. 12 is a partial schematic cross-sectional view of another embodiment of the display module of the electronic device shown in FIG. 4 along the line A-A. The support member 32 further includes a second buffer member 325. The second buffer member 325 is attached to the first connecting plate member 322, and the second buffer member 325 is positioned opposite the first buffer member 324. In other words, the second buffer member 325 is secured to the second surface. 3224 when the first buffer element 324 is attached to the first surface 3223. Alternatively, the second buffer element 325 is attached to the first surface 3223 when the first buffer element 324 is attached to the second surface 3224. An example in which the second buffer element 325 is attached to the second surface 3224, when the first buffer element 324 is attached to the first surface 3223, is used for description below.

[00167] With respect to the material and method of formation of the second buffer element 325, the material and method of formation of the first buffer element 324 in the first embodiment is applicable. The details are not repeated here.

[00168] It should be understood that the first buffer element 324 is located on the first surface 3223 of the first connecting plate element 322, and the second buffer element 325 is located on the second surface 3224 of the first connecting plate element 322. Therefore, the flexibility of the support element 32 facing the bending area 3182 of the display screen 31 is greatly improved. In this case, when the electronic device 100 is unfolded or folded, the support member 32 facing the bending region 3182 can reduce the impact on the display screen 31 during the folding process. In other words, when the electronic device 100 is folded or unfolded, the first buffer element 324 and the second buffer element 325 can jointly absorb the stress generated by bending.

[00169] In addition, the first buffer element 324 is located on the surface of the first connecting plate element 322 and is adjacent to the display screen 31, and the second buffer element 325 is located on the surface of the first connecting plate element 322, and faces away from the display screen 31. Therefore, when the electronic device 100 is in the unfolded state, the peripheral edges of the grooves or through holes on the first base plate 41, the second base plate 42, and the third base plate 43 of the rotation apparatus 40 extrude the second buffer member 325. Thus, since the second buffer member 325 has good flexibility, the second buffer member 325 has sufficient flexibility to absorb the partial extrusion force. In this case, the stress on the peripheral edges of the grooves 322 5 of the metal part 3221 is not concentrated, namely, the force with which the peripheral edges of the grooves 3225 of the metal part 3221 extrude the display screen 31 is small. Therefore, the appearance of a black spot, a bright line, and the like is largely prevented. on the display screen 31. Further, when the second buffer member 325 transmits the partial extrusion force to the first buffer member 324 via the first connecting plate member 322, the first buffer member 324 can also absorb the partial extrusion force again. In this case, the large extrusion force acting on the display screen 31 is further reduced. Therefore, the appearance of a black spot, a bright line, and the like is largely prevented. on the display screen 31.

[00170] The embodiments of the three designs of the display module 30 have been described above using the respective accompanying drawings. In three embodiments, support member 32 has good flexibility, rigidity, and hardness. The following describes a fourth embodiment of the display module 30 using the corresponding accompanying drawings, namely, another design of the support member 32.

[00171] In the fourth embodiment, the same content as in the first embodiment is not described again. In other words, most of the contents of the first embodiment can be directly applied to the fourth embodiment.

[00172] FIG. 13 is a partial schematic cross-sectional view of another embodiment of the display module of the electronic device shown in FIG. 4 along the line A-A. In the Z direction, the height of the first connecting plate member 322 is equal to the height of the first metal plate member 321 and the height of the second metal plate member 323. In addition, the groove slit 3225 of the metal piece 3221 faces the display screen 31. In another embodiment, the slot of the groove 3225 may face away from the display screen 31.

[00173] In addition, in the Y direction, the width L1 of the organic material portion 3222 is in the range of 0.15 mm to 3 mm. For example, L1 is equal to 0.15 mm, 0.26 mm, 1 mm, 2 mm, or 3 mm. The width L2 of the metal part 3221 between two adjacent organic material parts 3222 is 0.05 mm to 0.8 mm. L2 is equal to 0.05 mm, 0.1 mm, 0.2 mm, 0.5 mm, 0.6 mm or 0.8 mm.

[00174] It can be understood that the hardness of the metal part 3221 is greater than the hardness of the organic material parts 3222. It can be understood that the rigidity of the metal part 3221 is greater than the rigidity of the organic material parts 3222. In this case, the first connecting plate member 322 has both the metal part 3221 and the organic material parts 3222, the width L1 of the organic part 3222 is in the range of 0.15 to 3 millimeters, and the width L2 of the metal part 3221 between two adjacent parts from organic material 3222 is in the range from 0.05 mm to 0.8 mm. Therefore, the overall rigidity and hardness of the first connecting plate element 322 is moderate. In other words, the first connecting plate member 322 has good hardness, rigidity, and flexibility. When the electronic device 100 is in the unfolded state, the first connecting plate member 322 has sufficient rigidity and hardness to support the foldable area 3182 of the display screen 31 to prevent the foldable area 3182 of the display screen 31 from breaking or notching, namely, ensuring that the display module 30 had good surface flatness. When the electronic device 100 is unfolded or folded, the first connecting plate member 322 does not prevent the display screen 31 from bending.

[00175] In addition, the organic material parts 3222 are located in the grooves 3225 of the metal part 3221, so that the metal part 3221 and the organic material parts 3222 form a single structure, namely, the first connecting plate member 322 has good integrity. In this case, the bonding strength between the metal part 3221 and the organic material parts 3222 is good. Therefore, when the peripheral edges of the grooves or grooves on the first base plate 41, the second base plate 42, and the third base plate 43 extrude the first plate connecting member 322, since the bonding strength between the metal part 3221 and the organic material parts 3222 is in order, the metal part 3221 is not easily break to pierce or extrude the display screen 31.

[00176] In addition, when the peripheral edges of the grooves or grooves on the first base plate 41, the second base plate 42, and the third base plate 43 of the rotary apparatus 40 extrude the first connecting plate member 322, the organic material portions 3222 can absorb a partial extrusion force. In this case, the stress at the peripheral edges of the grooves 3225 is not overly concentrated. Therefore, the optically transparent adhesive 39 is prevented from protruding due to excessive extrusion, so that black spot, bright line, and the like are prevented. on the display screen 31.

[00177] In this implementation, the groove location method 3225 refers to the groove location method 3225 in the first embodiment. The details are not repeated here. In addition, with respect to the material and forming method of the metal part 3221, the material and forming method of the metal part is applicable. 3221 in the first embodiment. Details are not repeated here.
