Figure 5 is a rear view of the assembled front frame and display module provided in some embodiments of the present disclosure. Figure 6 is a schematic diagram of a middle frame provided in some embodiments of the present disclosure. Figure 7 is a cross-sectional schematic diagram of a display device provided in some embodiments of the present disclosure. Figure 8 is an enlarged view of area Q in Figure 7. Figure 9 is an enlarged view of area M in Figure 7. As shown in Figures 1 to 7, the display device includes: a front frame 1, a middle frame 3, a display module 2, a rear housing 5, and a driver assembly 4. The front frame 1 includes a cover plate 11 having a first light-transmitting portion 111. The middle frame 3 is disposed opposite the cover plate 11 and defines a first accommodating portion SP1 with the front frame 1. The display module 2 is disposed in the first accommodating portion SP1. The display module 2 includes a display area opposite the first light-transmitting portion 111. The display module 2 may be a liquid crystal display module, an OLED (Organic Light-Emitting Diode) display module, a Mini-LED (Mini Light-Emitting Diode) display module, a Micro-LED (Micro Light-Emitting Diode) display module, or a QLED (Quantum Dot Electroluminescent) display module. The rear housing 5 is disposed on a side of the middle frame 3 away from the cover plate 11 and defines a second accommodation portion SP2 with the middle frame 3. The drive assembly 4 is located in the second accommodation portion SP2 and is electrically connected to the display module 2 for providing a display drive signal to the display module 2 to control the display of the display module 2.

[0090] The middle frame 3 is detachably connected to the front frame 1 and the rear housing 5. "Detachably connected" in the disclosed embodiments means that the connection between the two is detachable; for example, the connection can be made by screws or bolts, or by a snap-fit ​​structure, or by a clamping structure.

[0091] In the embodiment of the present disclosure, since the middle frame 3 and the front frame 1, and the middle frame 3 and the rear shell 5 can be detachably connected, when the display module 2 needs to be maintained, it is only necessary to disassemble the front frame 1 and the middle frame 3, without disassembling the middle frame 3 and the rear shell 5; similarly, when the driving assembly 4 needs to be maintained, it is only necessary to disassemble the middle frame 3 and the rear shell 5, without disassembling the front frame 1 and the middle frame 3, which makes maintenance more convenient.

[0092] In some embodiments, as shown in Figures 3 to 5, the display module 2 includes a display panel 21 and a functional substrate 22. The functional substrate 22 is disposed on a side of the display panel 21 away from the support wall 32 and includes a main body 22a disposed opposite the display panel 21 and an edge 22b located around the main body 22a. The main body 22a is in contact with the display panel 21, and the edge 22a extends beyond the edge of the display panel 21.

[0093] In some embodiments, the display module 2 is a touch display module, that is, the functional substrate 22 is a touch substrate. In this case, the first light-transmitting portion 111 of the cover plate 11 is a hollow structure to facilitate the user to touch the display module 2 .

[0094] In some embodiments, as shown in Figures 1 to 5 , the front frame 1 further includes a front frame sidewall 12, which is connected to the cover plate 11. In one example, the front frame sidewall 12 and the cover plate 11 may be integrally formed. In another example, as shown in Figure 4 , the front frame 1 further includes a fitting wall 13 integrally formed with the front frame sidewall 12. The fitting wall 13 is arranged parallel to and fixedly connected to the cover plate 11, and is located on the side of the cover plate 11 facing the rear housing 5. For example, the cover plate 11 is connected to the fitting wall 13 using screws or other structures; in another example, the cover plate 11 is connected to the fitting wall 13 using adhesive, thereby maintaining a flat surface on the front frame 1.

[0095] In one example, the fitting wall 13 and the cover plate 11 form a first limiting groove, and the functional substrate 22 is located in the first limiting groove, thereby limiting the functional substrate 22 and then limiting the entire display module 2, preventing the display module 2 from shaking in the first accommodating portion SP1 along the length or width direction of the cover plate 11.

[0096] The shape of the first limiting groove can be adapted to the shape of the functional substrate 22. For example, the functional substrate 22 is a rectangular or rounded rectangle, and the first limiting groove is a rectangular rectangle. The length of the first limiting groove is the same as the length of the functional substrate 22, and the width of the first limiting groove is the same as the width of the functional substrate 22. The depth of the first limiting groove can be greater than the thickness of the functional substrate 22, or less than the thickness of the functional substrate 22, or equal to the thickness of the functional substrate 22. Figure 8 illustrates an example in which the depth of the first limiting groove is greater than the thickness of the functional substrate 22. It can be understood that the depth of the first limiting groove is the thickness of the fitting wall 13.

[0097] As shown in Figures 6 to 9, the middle frame 3 includes a support wall 32 and a middle frame side wall 31 connected to the support wall 32. The support wall 32 is disposed opposite the cover plate 11. The middle frame side wall 31 surrounds the support wall 32 and defines a first accommodating portion SP1 with the support wall 32 and the cover plate 11, and a second accommodating portion SP2 with the support wall 32 and the rear case 5. The middle frame side wall 31 is detachably connected to the front frame side wall 12 and the rear case 5.

[0098] In some embodiments, as shown in FIG8 , the middle frame 3 and the front frame 1 are fastened together using a first snap-fit ​​structure 01. The first snap-fit ​​structure 01 includes a first hook 01a and a first slot 01b. The first hook 01a is located on the front frame sidewall 12, and the first slot 01b is located on the middle frame sidewall 31. Alternatively, the first hook 01a can be located on the middle frame sidewall 31, and the first slot 01b can be located on the front frame sidewall 12. The middle frame 3 and the rear cover 5 are fastened together using a second snap-fit ​​structure 02. The second snap-fit ​​structure 02 includes a second hook 02a and a second slot 02b. The second hook 02a is located on the middle frame sidewall 31, and the second slot 02b is located on the rear cover 5. Alternatively, the second hook 02a can be located on the rear cover 5, and the second slot 02b can be located on the middle frame sidewall 31. Using snap-fit ​​structures to fasten the front frame 1 to the middle frame 3, and the middle frame 3 to the rear cover 5, facilitates assembly and disassembly of the display device.

[0099] In a specific example, the middle frame side wall 31 may include a connected snap-in member 31a and a main frame 31b. The snap-in member 31a is located on the side of the main frame 31a facing the cover plate 11 and is snap-fitted to the front frame side wall 12. For example, a first snap-in slot 01b is provided on the snap-in member 31a. The number of snap-in members 31a may be multiple and evenly spaced along the circumference of the main frame 31a. The main frame 31b, the support wall 32, and the rear shell 5 define a second accommodating portion SP2. The main frame 31b may include: a first wall 311 and a second wall 312 arranged along a first direction, and a third wall 313 and a fourth wall 314 arranged along a second direction; the second direction is perpendicular to the first direction. The first wall 311, the second wall 312, the third wall 313, and the fourth wall 314 are all snap-fitted to the rear shell 5 via a second snap-fit ​​structure 02.

[0100] As shown in Figure 8, the middle frame 3 may further include a retaining wall 33, which is fixedly connected to the support wall 31 and is arranged around the display panel 21. The edge portion 22b of the functional substrate 22 is clamped between the retaining wall 33 and the cover plate 11, thereby defining the position of the functional substrate 22 in the thickness direction of the cover plate 11, and further defining the position of the display module 2. In this case, there is no need to use additional connectors (such as screws, adhesive, etc.) to connect the display module 2 to the front frame 1 and / or the middle frame 3, making it easier to disassemble the display module 2 when maintenance is required.

[0101] As shown in Figures 8 and 9, a buffer layer 21c may be provided between the display module 2 and the support wall 32 of the middle frame 3 to prevent the support wall 32 from squeezing or bumping the display panel 21 during use or movement of the display device. The buffer layer 21c may be, for example, a foam pad.

[0102] As shown in FIG. 8 , a deformation space Sp0 is defined between the clamping member 31 a and the retaining wall 33 , so that the clamping member 31 a can deform toward the retaining wall 33 , thereby facilitating the clamping of the clamping member 31 a with the front frame sidewall 12 .

[0103] As shown in Figures 8 and 9, the middle frame 3 also includes a pressing portion 34 connected to the support wall 32 and the main frame 31b. The pressing portion 34 extends from the inner side of the main frame 31b toward the middle of the second accommodating portion SP2 and presses on the edge of the driving component 4, so that the driving component 4 is clamped between the pressing portion 34 and the rear shell 5.

[0104] The display device in the embodiments of the present disclosure can be, in particular, a small-sized display device. For example, a tablet computer. In some embodiments, as shown in Figures 1, 2, and 7, the display device can further include a bracket 7, which is rotatably connected to the rear housing 5 and is used to adjust the angle between the display surface of the display module 2 and the support surface on which the display device is located. The display surface of the display module 2 is the surface used for displaying, and specifically, it can be the surface of the display module 2 away from the rear housing 5.

[0105] FIG10 is an exploded view of the rear housing 5 and bracket 7 provided in some embodiments of the present disclosure. FIG11 is a cross-sectional view of the rotating shaft 80 provided in some embodiments of the present disclosure after being installed on the shaft seat 52. FIG12 is a schematic diagram of the second seat body in FIG11. FIG13 is a cross-sectional view of the rotating shaft 80 provided in some embodiments of the present disclosure after being installed on the shaft seat 52 in another direction. As shown in FIG10 to FIG13, the rear housing 5 includes: a back plate 50 and a shaft seat 52. The back plate 50 is arranged opposite to the drive assembly 4 and is detachably connected to the middle frame 3 via a second snap-fit ​​structure 02. The shaft seat 52 is provided on the back plate 50 and has an axis hole 52v formed therein. The axis hole 52v extends in a direction parallel to the display surface of the display module 2. For example, if the display module 2 is a rectangular structure, the axis hole 52v extends in a direction parallel to the length or width of the display module 2.

[0106] In some embodiments, as shown in Figures 10 and 13, the shaft seat 52 includes a first seat body 521 and a second seat body 522. The first seat body 521 is fixed to the back plate 50. For example, the first seat body 521 and the back plate 50 can form an integral structure. The second seat body 522 is disposed on a side of the first seat body 521 away from the back plate 50 and is detachably connected to the first seat body 521, thereby facilitating the installation of the rotating shaft 80 and the shaft seat 52. For example, the first seat body 521 and the second seat body 522 can be connected by fasteners such as screws 523. A first groove 521v is defined on the side of the first seat body 521 facing the second seat body 522, and a second groove 522v is defined on the side of the second seat body 522 facing the first seat body 521. The first groove 521v and the second groove 522v form a shaft hole 52v. Of course, the first base body 521 may also have a first groove 521v formed on the side facing the second base body 522, the surface of the second base body 522 facing the first base body 521 may be flat, and the first groove 521v and the second base body 522 may form an axial hole 52v; or, the second base body 522 may have a second groove 522v formed on the side facing the first base body 521, the surface of the first base body 521 facing the second base body 522 may be flat, and the second groove 522v and the first base body 521 may form an axial hole 52v.

[0107] As shown in Figures 11 and 12, in the embodiment of the present disclosure, the first base 521 has a mounting protrusion 521a on the side facing the second base 522. For example, a threaded hole is formed in the mounting protrusion 521a, and the second base 522 is detachably connected to the mounting protrusion 521a via a fastener such as a screw 523. Accordingly, the second base 522 is provided with a through hole 522b corresponding to the screw 523. Furthermore, the second base 522 also has a second limiting groove 522s on the side facing the first base 521. At least a portion of the mounting protrusion 521a is located in the second limiting groove 522s, thereby facilitating the alignment and installation of the first base 521 and the second base 522.

[0108] As shown in Figures 1 and 10 to 13, the display device further includes: a damping member 86 and a rotating shaft 80 fixedly connected to the bracket 7. For example, the two ends of the bracket 7 are respectively connected to two rotating shafts 80; the bracket 7 and the rotating shaft 80 can be an integral structure. The rotating shaft 80 passes through the shaft hole 52v and can rotate around its own axis relative to the shaft seat 52. The damping member 86 is located in the shaft hole 52v and is sleeved on the rotating shaft 80. The damping member 86 is used to provide a rotational damping force for the rotating shaft 80. The damping member 86 has a certain degree of elasticity. Its inner side is tightly wrapped around the rotating shaft 80, and its outer side is tightly wrapped by the shaft seat 52, so that when the rotating shaft 80 rotates, the damping member 86 does not rotate, thereby providing a rotational damping force f1 to the tightly wrapped rotating shaft 80, which can achieve multi-angle transformation and infinite angle adjustment, so that the bracket 7 can hover at any angle.

[0109] In some embodiments, the orthographic projection of the shaft hole 52v onto a reference plane perpendicular to the axis of the rotating shaft 80 is a polygon, and the shape of the damping member 86 matches the shape of the shaft hole 52v, thereby ensuring that the damping member 86 does not rotate with the rotating shaft 80. The shape of the damping member 86 matches the shape of the shaft hole 52v, meaning that the outer surface of the damping member 86 matches the shape of the inner wall of the shaft hole 52v, thereby ensuring that there is no gap between them. For example, the shaft hole 52v is a square hole, and the damping member 86 has a square outer surface and a round inner surface.

[0110] In some embodiments, as shown in Figures 10 and 13 , the bracket 7 includes a first support arm 71 and a second support arm 72. The first support arm 71 and the second support arm 72 are each connected to two rotating shafts 80. Each rotating shaft 80 is located on the side of the first support arm 71 or the second support arm 72 closer to the center of the rear housing 5. The two rotating shafts 80 pass through two shaft seats 52, which are located on opposite sides of the rear housing 5. The first support arm 71 and the second support arm 72 are located on the outside of the middle frame sidewall 31, that is, on the side of the middle frame sidewall 31 away from the second accommodating portion SP2; the shaft seats 52 are located on the side of the middle frame sidewall 31 closer to the second accommodating portion SP2. As shown in Figures 1 and 2 , the middle frame sidewall 31 has an escape notch 31v. The two rotating shafts 80 connected to the first support arm 71 and the second support arm 72 pass through the escape notch 31v and extend into the shaft hole 52v.

[0111] As shown in Figures 10 and 13, the rotating shaft 80 includes a first shaft portion 801 and a second shaft portion 802. The first shaft portion 801 is connected between the second shaft portion 802 and the bracket 7 and is located within the shaft hole 52v. The second shaft portion 802 is located outside the shaft hole 52v. The display device also includes a locking structure provided on the second shaft portion 802 for limiting axial movement of the rotating shaft 80 to prevent the rotating shaft 80 from falling out of the shaft hole 52v.

[0112] Furthermore, as shown in Figures 10 and 13, the display device also includes a damping washer 85, which is sleeved on the second shaft portion 802 and located between the locking structure and the shaft seat 52. When the rotating shaft 80 rotates, the locking structure rotates accordingly, causing the damping washer 85 to contact the side of the shaft seat 52 to generate a rotational damping force f2, and also generates a rotational damping force f3 with the locking structure, thereby further ensuring the support stability of the bracket 7 for the display device at any angle.

[0113] In some embodiments, as shown in Figures 10 to 13 , the retaining structure includes a spring washer 83, a flat washer 84, and a fastener 82a. The spring washer 83 is sleeved onto the second shaft portion 802; the flat washer 84 is sleeved onto the second shaft portion 802 and is located on the side of the spring washer 83 away from the shaft seat 52. The fastener 82a is fixed to the second shaft portion 802 and is located on the side of the flat washer 84 away from the shaft seat 52. In some embodiments, the fastener 82a includes a first nut 82 threadedly connected to the second shaft portion 802. The first nut 82 may be a locknut.

[0114] When the shaft 80 rotates, the damping element 86 does not rotate, but instead generates a rotational damping force f1 on the shaft 80. One side of the damping washer 85 contacts the side of the shaft seat 52, generating a rotational damping force f2, while the other side of the damping washer 85 contacts the flat washer 84, generating a rotational damping force f3. The locking locknut, spring washer 83, and flat washer 84 clamp the damping washer 85, and the greater the preload force, the greater the generated rotational damping force f2 and f3. Assuming the thread tightening force is F, the final damping force that dampens the rotation of the shaft 80 is f. To achieve a damping effect, F > f1 + max(f2, f3). The damping force on one side of the shaft 80, f = f1 + min(f2, f3). This ensures that the first nut 82, flat washer 84, and spring washer 83 all rotate with the shaft 80, and the damping element 86 and damping washer 85 generate a damping effect. The damping effect can be adjusted by adjusting the pre-tightening force of the first nut 82. When F < f1 + max (f2, f3), when the shaft 80 is rotated, the first nut 82 will become loose and the damping will fail.

[0115] FIG14 is a three-dimensional view of the bracket 7 provided in some other embodiments of the present disclosure after being installed on the shaft seat 52, FIG15 is an exploded view of the bracket 7 provided in some other embodiments of the present disclosure after being installed on the shaft seat 52, FIG16 is a side view of the bracket 7 provided in some other embodiments of the present disclosure after being installed on the shaft seat 52, and FIG17 is a schematic diagram of the groove on the rotating shaft 80 provided in some other embodiments of the present disclosure. As shown in FIG14 to FIG17, in some other embodiments, a groove 802 is provided on the second shaft portion 802, and the fastener 82a includes a second nut 87 and a clamping member 88. The second nut 87 is threadedly connected to the second shaft portion 802, and the clamping member 88 is located on the side of the second nut 87 away from the flat washer 84 and is clamped with the groove 802. The second nut 87 can be an ordinary nut, and does not have to be a lock nut; the clamping member 88 can be an E-type retaining spring. When assembling fastener 82a and damping washer 85, damping washer 85, spring washer 83, and flat washer 84 are first placed on rotating shaft 80. After tightening second nut 87 and applying sufficient preload, the E-shaped retaining spring is engaged, preventing second nut 87 from retracting, thereby ensuring a constant damping force. For example, as shown in FIG17 , the second portion of rotating shaft 80 is provided with two sections of external threads 8011 and 8012, located on either side of groove 802. At the location of groove 802, the diameter of the second portion of rotating shaft 80 is equal to the inner diameter of the E-shaped retaining spring, for example, both being 2.5 mm, to prevent second nut 87 from dislodging.

[0116] Figure 18 is a schematic diagram of the bracket 7 provided in some embodiments of the present disclosure changing from a supporting state to a folded state. As shown in Figures 2, 10 and 18, the bracket 7 includes, in addition to the above-mentioned first support arm 71 and the second support arm 72, a connecting arm 73. The first end of the first support arm 71 and the first end of the second support arm 72 are both rotatably connected to the rear shell 5, and the connecting arm 73 is connected between the second end of the first support arm 71 and the second end of the second support arm 72. The connecting arm 73 and the first support arm 71 and the second support arm 72 can be an integral structure. The buffer sleeve 81 is sleeved on the connecting arm 73, and the setting of the buffer sleeve 81 can play an anti-slip role when the support frame is in the supporting state. For example, the buffer sleeve 81 can be a silicone sleeve. The number of the buffer sleeves 81 can be one or more.

[0117] In some embodiments, as shown in FIG18 , when the bracket 7 is in the folded state, it is sleeved on the outside of the middle frame side wall 31. The phrase “sleeved on the outside of the middle frame side wall 31” does not mean that the bracket 7 completely surrounds the middle frame side wall 31, but rather that the bracket 7 may be in a state of semi-surrounding the middle frame side wall 31. Specifically, the rotating shaft 80 extends along the first direction. As shown in FIG2 , the main frame 31b includes: a first wall 311 and a second wall 312 arranged along the first direction, and a third wall 313 and a fourth wall 314 arranged along the second direction. The second direction is perpendicular to the first direction, and an avoidance notch 31v is provided on the first wall 311 and the second wall 312. The two rotating shafts 80 connected to the bracket 7 pass through the avoidance notches 31v on the first wall 311 and the second wall 312, respectively. When the bracket 7 is completely folded, the first support arm 71 of the bracket 7 is arranged opposite to the first wall 311, the second support arm 72 is arranged opposite to the second wall 312, and the connecting arm 73 is arranged opposite to the third wall 313 or the fourth wall 314, thereby reducing the space occupied by the entire display device when the bracket 7 is in the folded state.

[0118] In some embodiments, the distances from the third wall 313 and the fourth wall 314 to the axis of the rotating shaft 80 are equal, so that the bracket 7 can achieve a rotation of 0 to 180 degrees.

[0119] In one example, the lengths of the first support arm 71 and the second support arm 72 can meet the following conditions: when the connecting arm 73 is located at the connection position between the outer surface of the middle frame side wall 31 and the back of the rear shell 5 (such as position A in Figure 18), the connection position produces a slight squeeze on the buffer pad, and eventually the first support arm 71 and the second support arm 72 can be parallel to the back of the rear shell 5.

[0120] Among them, the longitudinal cross-section of the connecting arm 73 can be a rectangular structure. When the bracket 7 is in a folded state, the surface of the buffer pad facing the middle frame side wall 31 is in contact with the third wall 313 or the fourth wall 314, and the connecting arm 73 can no longer move toward the direction close to the cover plate 11, that is, the extreme position of the bracket 7 is: the first support column, the second support column and the back of the rear shell 5 are parallel.

[0121] In some embodiments, the axes of the two rotating shafts 80 connected to the bracket 7 are located on the same straight line, and the rear shell 5 is mirror-symmetrical about the straight line where the axes of the rotating shafts 80 are located, thereby reducing the error rate during assembly.

[0122] In some embodiments, when the rotating shaft 80 extends in the first direction, the ends of the front frame 1 in the second direction extend beyond the third wall 313 and the fourth wall 314, respectively. That is, when the rotating shaft 80 extends in the left-right direction, the upper end of the front frame 1 is higher than the third wall 313, and the lower end of the front frame 1 is lower than the fourth wall 314, thereby concealing the bracket 7 in the folded state. Similarly, when the rotating shaft 80 extends in the second direction, the ends of the front frame 1 in the first direction extend beyond the first wall 311 and the second wall 312, respectively.

[0123] As shown in Figures 1 and 10, the rear housing 5 further includes reinforcing ribs 51 on the back plate 50 to improve the strength of the rear housing 5. The driving assembly 4 rests against the reinforcing ribs 51 to prevent the driving assembly 4 from loosening.

[0124] In one example, the back cover 5 includes at least one set of reinforcing ribs 51. Each set of reinforcing ribs 51 includes a plurality of first reinforcing ribs 51a arranged along the second direction and a plurality of second reinforcing ribs 51b arranged along the first direction. The first reinforcing ribs 51a extend along the first direction, while the second reinforcing ribs 51b extend along the second direction. Within the same set, a plurality of second reinforcing ribs 51b arranged along the first direction are disposed between two adjacent first reinforcing ribs 51a. Each second reinforcing rib 51b is connected at both ends to two first reinforcing ribs 51a, thereby increasing the overall support strength of each set of reinforcing ribs 51 and, consequently, the overall strength of the back cover 5.

[0125] In one example, the reinforcing ribs 51 on the back plate 50 may also be mirror-symmetrical about the axis of the rotating shaft 80. For example, the rear housing 5 includes two sets of reinforcing ribs 51, and the two sets of reinforcing ribs 51 are mirror-symmetrical about the axis of the rotating shaft 80, so that the driving assembly 4 is subjected to evenly distributed support force.

[0126] In one example, the back plate 50 may be further provided with auxiliary reinforcing ribs 53 to further enhance the overall strength of the rear housing 5. The height of the auxiliary reinforcing ribs 53 may be less than that of the first and second reinforcing ribs 51a, 51b. That is, the auxiliary reinforcing ribs 53 do not support the drive assembly 4 but serve only to enhance the strength of the rear housing 5. The distribution of the auxiliary reinforcing ribs 53 may be configured as needed; for example, the auxiliary reinforcing ribs 53 may extend along the second direction.

[0127] As shown in Figure 1, the drive assembly 4 includes a mounting plate 45, a battery 42, a system motherboard 41, and a microprocessor 44. The mounting plate 45 rests on the reinforcing ribs 51. In one embodiment, the mounting plate 45 includes a mounting base 451 and mounting side panels 452 connected to the edges of the mounting base 451. The mounting base 451 and mounting side panels 452 may be integral structures. The mounting base 451 rests on the reinforcing ribs 51, while the mounting side panels 452 rest on the pressing portion 34 of the middle frame 3. Thus, the pressing portion 34 and the rear case 5 clamp the mounting plate 45. This eliminates the need for additional connectors to secure the mounting plate 45 to the rear case 5 or the middle frame 3, facilitating disassembly and maintenance of the display device.

[0128] The battery 42 is fixed to the side of the mounting base 451 facing the middle frame 3 and is used to power the system motherboard 41. The system motherboard 41 is fixed to the side of the mounting base 451 facing the middle frame 3. For example, the system motherboard 41 can be fixed to the side of the mounting base 451 facing the middle frame 3 using fasteners such as screws. The system motherboard 41 is electrically connected to the battery 42 and the display module 2. As shown in Figure 2, the middle frame 3 is provided with a first hollow portion 32a, a second hollow portion 32b, and a second hollow portion 32b. The system motherboard 41 is electrically connected to the display module 2 via a first connecting line (not shown), and the first connecting line passes through the first hollow portion 32a.

[0129] The microprocessor 44 is fixed to the side of the middle frame 3 facing the mounting plate 45. For example, a positioning column is provided on the side of the middle frame 3 facing the back plate 50, and the microprocessor 44 is fixed to the positioning column by a screw. The microprocessor 44 is electrically connected to the system motherboard 41 and is electrically connected to the display module 2 through a second connecting line (not shown), and the second connecting line passes through the first hollow portion 32a. Among them, a third hollow portion 32c is also provided on the support wall 32, and the microprocessor 44 can be set at the position of the third hollow portion 32c, which is conducive to reducing the overall thickness of the middle frame 3 and the microprocessor 44 and reducing the overall weight of the display device. It should be noted that the microprocessor 44 is set at the position of the third hollow portion 32c, which means that the positive projection of the microprocessor 44 on the back plate 50 overlaps with the positive projection of the third hollow portion 32c on the back plate 50.

[0130] The size and shape of the first hollow portion 32a can be adjusted according to actual needs, thereby ensuring that the support wall 32 supports the display module 2 while reducing the overall weight of the middle frame 3. In one example, the area of ​​the first hollow portion 32a is larger than the area of ​​either the second hollow portion 32b or the third hollow portion 32c.

[0131] As shown in Figure 1 , the drive assembly 4 also includes a keypad 43, which is fixed to the side of the mounting plate 45 facing away from the rear housing 5 and is electrically connected to the system motherboard 41. The keypad 43 has a first key 431, which can protrude from the sidewall of the mounting plate 45. A trigger 31s is provided on the sidewall 31 of the middle frame. The trigger 31s contacts the first key 431 on the keypad 43. By controlling the trigger 31s, the first key 431 can be indirectly pressed. For example, the first key 431 is used to provide an on / off signal to the system motherboard 41 to control the power on / off of the display module 2.

[0132] In one example, the battery 42 is roughly rectangular in structure, the system mainboard 41 is L-shaped, and the system mainboard 41 and the keypad 43 are located on adjacent sides of the battery 42, thereby facilitating the battery 42 to power the system mainboard 41 and the keypad 43 and improving the structural compactness of the drive assembly 4.

[0133] As shown in Figures 1 and 2, the cover plate 11 further includes a second light-transmitting portion 112 located to one side of the first light-transmitting portion 111. For example, the second light-transmitting portion 112 and the first light-transmitting portion 111 are aligned along the second direction. The display device also includes a camera 6, which is fixed to the side of the cover plate 11 facing the rear housing 5 and extends through the second hollow portion 32b. The orthographic projection of the fitting wall 13 of the front frame 1 on the cover plate 11 is located outside the area where the second light-transmitting portion 112 is located to prevent obstruction of light to the camera 6.

[0134] In some embodiments, as shown in FIG6 , the middle frame 3 further includes a support member 35 located in the first accommodation portion SP1. The orthographic projections of the support member 35 and the camera 6 on the plane of the cover plate 11 are located on the same side as the orthographic projection of the display module 2 on the plane of the cover plate 11. The support member 35 is connected to the middle frame sidewall 32 and abuts against the fitting wall 13, thereby supporting the cover plate 11 and preventing the corresponding portion of the cover plate 11 from sagging due to force.

[0135] For example, as shown in Figures 6 and 9, the support wall 32 of the middle frame 3 includes a first support sub-wall 321 and a second support sub-wall 322. The first support sub-wall 321 and the second support sub-wall 322 can be parallel or approximately parallel to the cover plate 11. The retaining wall 33 is arranged around the first support sub-wall 321. It should be noted that the "surrounding" here does not mean that the retaining wall 33 is a closed annular structure, it can also be a semi-closed structure. The support member 35 is arranged on the side of the second support sub-wall 322 facing the cover plate 11, and the second support sub-wall 322 has the above-mentioned second hollow portion 32b. Among them, the support member 35 can include a plurality of support plates, and the plurality of support plates should avoid the position of the second hollow portion 32b. For example, the second support sub-wall 322 can be on the same plane as the pressing portion 34.

[0136] For example, as shown in Figures 2 and 4 , the surface of the mating wall 13 facing the rear housing 5 is provided with two positioning posts 1203 and two studs 1202. The two positioning posts 1203 are located at two diagonally opposite positions on the camera 6 circuit board, while the studs 1202 are located at two other diagonally opposite positions. The positioning posts 1203 ensure the accurate positioning of the camera 6 circuit board, which is then secured to the positioning posts 1203 and studs 1202 using screws. The lens of the camera 6 is positioned opposite the second light-transmitting portion 112. The camera 6 can transmit signals to the driver assembly 4; for example, the camera 6 can capture facial image information of a user and transmit it to the system motherboard 41. The system motherboard 41 processes the facial image information captured by the camera 6 and controls the display of the display module 2. For example, the camera 6 can be connected to the system motherboard 41 via a cable within the display device; however, it can also be electrically connected to an external control device via a cable, which in turn is electrically connected to the system motherboard 41.

[0137] In addition, the display device may further include a light sensor, for example, the light sensor may be used to detect the distance between an object or person in front of the display device and the display device.

[0138] The portion of the cover plate 11 other than the first light-transmitting portion 111 and the second light-transmitting portion 112 is a light-shielding portion. For example, a light-shielding material may be coated on the cover plate 11 other than the first light-transmitting portion 111 and the second light-transmitting portion 112. The cover plate 11 may be made of glass or a transparent organic material, such as polyimide (PI).

[0139] It is understood that the above embodiments are merely exemplary embodiments for illustrating the principles of the present disclosure, and the present disclosure is not limited thereto. Those skilled in the art may make various modifications and improvements without departing from the spirit and substance of the present disclosure, and such modifications and improvements are also considered to be within the scope of protection of the present disclosure.
