[0041] In order to make the above-mentioned purposes, features and advantages of the embodiments of the present application more obvious and easy to understand, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative labor fall within the scope of protection of the present application.

[0042] Figure 1 The structure of the display device in the related art is shown in FIG. 1. Please refer to FIG. 1. Figure 1 In the related art, the frame 200' includes the frame body 201' and the support portion 202' protruding from the frame body 201', the backlight assembly 100' is arranged between the support portion 202' and the back shell 400', and the back shell 400' is connected with the frame body 201' by bolts. In this way, the thickness of the frame body 201' usually needs to be greater than the size of the head of the bolt, so that the back shell 400' is stably connected with the frame 200'. However, this also leads to a large thickness of the frame body 201', and further leads to a large width of the non-display area of the display device 10', which does not meet the narrow frame design requirement of the display device 10'.

[0043] In view of this, this application provides a display device, wherein the display device includes a connector, a frame is snapped into the connector, and the connector is detachably connected to the rear shell, that is, the frame and the rear shell are indirectly connected. Furthermore, the snap-fit ​​connection between the frame and the connector, compared to the bolted connection method in related technologies, allows the frame body in this embodiment to have a smaller thickness, resulting in a smaller width of the non-display area of ​​the display device, thus meeting the narrow bezel design requirements of the display device.

[0045] Please see Figures 2 to 8 This embodiment provides a display device 10, which can be a mobile phone, tablet, monitor, etc. This embodiment does not limit the type of display device 10. For example, the display device 10 can be a monitor with a capacitive touch screen.

[0046] The display device 10 includes a light-emitting element (not shown), which serves as a backlight source for emitting light. The display device 10 also includes a backlight assembly 100 and a display module 500. The backlight assembly 100 and display module 500 are structures well-known to those skilled in the art, and this embodiment is not limiting. Exemplarily, the display assembly includes a diffuser plate / reflector 110, a light guide plate 120, and a brightness enhancement plate 130 stacked sequentially. The reflector 110 is disposed behind the light-emitting element and is used to reflect the light emitted by the light-emitting element toward the front of the display device 10. The light guide plate 120 is disposed in front of the reflector 110 and is used to convert a point light source into a surface light source. The brightness enhancement plate 130 is disposed in front of the light guide plate 120 and is used to increase the brightness of the light. The display module 500 is used to display images, text, and other information. It is understood that the display device 10 also includes a cover glass 600, which is located in front of the display module 500 and is used to protect the display module 500.

[0047] The display device 10 further comprises a frame 200, the frame 200 is arranged outside the periphery of the backlight assembly 100, that is, the frame 200 is a ring-shaped frame structure, used for fixing the backlight assembly 100, the display module 500 and the cover glass 600.

[0048] In some embodiments, the frame 200 comprises a frame body 201, the frame body 201 is arranged outside the backlight assembly 100, and the frame body 201 further comprises a support portion 202, the support portion 202 protrudes from the inner side of the frame body 201, wherein the backlight assembly 100 is located at the rear side of the support portion 202, and the display module 500 and the cover glass 600 are arranged at the front side of the support portion 202, and the support portion 202 is used for supporting the display module 500 and the cover glass 600. The cover glass 600 can be fixed on the wall surface of the front side of the frame body 201 by an adhesive.

[0049] In this way, during the assembly process of the display device 10, the backlight assembly 100 can be placed on the support portion 202 after the frame 200 is assembled and formed, and then the rear shell 400 is installed.

[0050] The frame 200 can be a rectangular frame, a circular frame, etc. Taking the frame 200 as a rectangular frame as an example, the frame 200 comprises a plurality of side strips 230, the plurality of side strips 230 are sequentially connected at the head and tail, wherein the number of the side strips 230 is four, and the four side strips 230 are usually arranged at the top side X, the bottom side Y, the left side M and the right side N of the display module 500.

[0051] The display device 10 further comprises a rear shell 400, the rear shell 400 is arranged at the rear side of the backlight assembly 100, used for supporting the backlight assembly 100 and the display module 500.

[0052] In some embodiments, the display device 10 further comprises a connecting piece 300, the connecting piece 300 is clamped with the frame 200, wherein the frame body 201 is clamped with the connecting piece 300, and the connecting piece 300 extends to the inner side of the frame 200, and the rear shell 400 is detachably connected with the connecting piece 300, wherein the backlight assembly 100 is located between the support portion 202 and the connecting piece 300.

[0053] The rear shell 400 and the connecting piece 300 can be clamped and connected. In order to improve the connection stability, in some embodiments, the display device 10 further comprises a threaded connecting piece (not shown), the rear shell 400 is connected with the connecting piece 300 through the threaded connecting piece, the axis of the threaded connecting piece is perpendicular to the rear shell 400, the connection stability between the rear shell 400 and the connecting piece 300 is higher, and the rear shell 400 and the connecting piece 300 are easy to disassemble and assemble.

[0054] In this way, the frame 200 is indirectly connected with the rear shell 400 through the connecting piece 300. Meanwhile, the frame 200 is connected with the connecting piece 300 through the clamping connection. It can be understood that the size occupied by the clamping structure can be smaller than the size of the bolt head in the related art, that is, the frame body 201 in the embodiment can have a smaller thickness than the frame body 201' in the related art, so that the width of the non-display area of the display device 10 is smaller, and the design requirement of narrow frame of the display device 10 is met.

[0055] To realize the clamping connection between the frame 200 and the connecting piece 300, in some embodiments, one of the frame 200 and the connecting piece 300 is provided with a clamping protrusion 310, and the other is provided with a clamping portion 210. The clamping portion 210 is a groove-shaped structure for accommodating the clamping protrusion 310. In this way, the clamping protrusion 310 can extend into the clamping portion 210 and be clamped with the clamping portion 210.

[0056] The cross-sectional shape of the clamping protrusion 310 can be rectangular, circular, dovetail-shaped, etc. In some embodiments, referring to Figure 2 , Figure 3 and Figure 8 , the cross-sectional shape of the clamping protrusion 310 is approximately T-shaped. In this way, after the clamping protrusion 310 extends into the clamping portion 210, the clamping protrusion 310 can be prevented from being separated from the clamping portion 210 through the opening of the clamping portion 210, and the clamping stability between the clamping protrusion 310 and the clamping portion 210 is higher.

[0057] The clamping protrusion 310 can be arranged on the frame body 201, and correspondingly, the clamping portion 210 is arranged on the connecting piece 300. In some embodiments, the clamping protrusion 310 is arranged on the connecting piece 300, and the clamping portion 210 is arranged on the frame 200, that is, the clamping portion 210 is arranged on the frame body 201. In this way, when the protruding clamping protrusion 310 is arranged on the inner wall surface of the frame body 201, the size of the frame 200 needs to be increased to avoid the clamping protrusion 310 from interfering with the backlight assembly 100.

[0058] The clamping portion 210 can be arranged on the rear side surface of the frame body 201. In some embodiments, the opening of the clamping portion 210 faces the inner side of the frame 200 facing the backlight assembly 100, that is, the clamping portion 210 is arranged on the inner side surface of the frame body 201. Meanwhile, since the axis of the threaded connecting piece is perpendicular to the rear shell 400, the rear shell 400 can be connected with the rear wall surface of the threaded connecting piece. In this way, after the rear shell 400 is connected with the connecting piece 300, the connecting piece 300 can be accommodated in the cavity surrounded by the rear shell 400 and the frame 200, so as to simplify the appearance of the display device 10.

[0059] The clamping portion 210 can extend along the vertical direction of the rear shell 400, so that the clamping protrusion 310 can extend into the clamping portion 210 along the vertical direction of the rear shell 400. At this time, a locking structure can be arranged between the clamping protrusion 310 and the clamping portion 210 to prevent the clamping protrusion 310 and the clamping portion 210 from being separated from each other.

[0060] In some embodiments, the clamping portion 210 extends along the circumferential direction of the frame 200, that is, the clamping portion 210 extends along the length direction of the side bar 230 of the corresponding side. In this way, by arranging the T-shaped clamping protrusion 310, after the clamping protrusion 310 extends into the clamping portion 210, the outer wall surface of the clamping protrusion 310 abuts against the inner wall surface of the clamping portion 210, and the connection piece 300 and the frame 200 can be prevented from being separated from each other due to the movement of the connection piece 300 along the vertical direction of the rear shell 400.

[0061] To facilitate the clamping of the clamping protrusion 310 and the clamping portion 210, the extension length of the clamping portion 210 can be equivalent to the length direction of the side bar 230 of the corresponding side.

[0062] Correspondingly, the extension length of the clamping protrusion 310 can also be equivalent to the length direction of the side bar 230 of the corresponding side, and the clamping protrusion 310 can extend into the clamping portion 210 through the end of the clamping portion 210.

[0063] To reduce the manufacturing cost of the display device 10, the extension length of the clamping protrusion 310 can also be less than the length of the side bar 230 of the corresponding side. The number of clamping protrusions 310 can be one. The number of clamping protrusions 310 can also be multiple (such as Figures 4 to 7 ), and the multiple clamping protrusions 310 are arranged at intervals along the circumferential direction of the frame 200 to reduce the manufacturing cost. At the same time, the contact area between the clamping protrusion 310 and the clamping portion 210 is small, the friction between the connection piece 300 and the frame 200 is small, and the assembly is easy.

[0064] In some embodiments, the extension length of the clamping protrusion 310 along the circumferential direction of the frame 200 can also be less than the length of the side bar 230 of the corresponding side, that is, the extension length of the clamping protrusion 310 along the circumferential direction of the frame 200 is less than the extension length of the clamping portion 210 along the circumferential direction of the frame 200.

[0065] It can be understood that during the assembly process of the display device 10, the frame 200 is usually assembled first, that is, the four side bars 230 are surrounded to form a rectangular frame structure. At this time, the end of the clamping portion 210 on the side bar 230 is blocked, and the clamping protrusion 310 is not easy to extend into the clamping portion 210 from the end of the clamping portion 210.

[0066] In some embodiments, the clamping portion 210 is provided with a lead-in notch 220 which is vertically communicated with the inner and outer sides of the clamping portion 210. Specifically, the clamping portion 210 is a groove-shaped structure formed on the frame body 201, and the lead-in notch 220 can pass through the rear side wall of the clamping portion 210 (as shown in FIGS. 17 and 18). Figure 6 and Figure 7 As shown in FIGS. 17 and 18.

[0067] In some embodiments, the lead-in notch 220 has an extension length greater than or equal to that of the clamping protrusion 310, and the clamping protrusion 310 is configured to move along the clamping portion 210 after extending into the clamping portion 210 through the lead-in notch 220, so that the clamping protrusion 310 is arranged staggered with the lead-in notch 220.

[0068] That is, during the connection of the connecting piece 300 and the frame 200, the clamping protrusion 310 can be aligned with the lead-in notch 220; secondly, the connecting piece 300 is moved vertically along the rear shell 400 until the clamping protrusion 310 extends into the clamping portion 210 through the lead-in notch 220; then, the connecting piece 300 is moved along the extension direction of the clamping portion 210 until the clamping protrusion 310 is arranged staggered with the lead-in notch 220, so as to avoid the clamping protrusion 310 from being pulled out of the clamping portion 210 through the lead-in notch 220; that is, the connection of the connecting piece 300 and the edge strip 230 is achieved.

[0069] In this way, during the assembly of the display device 10, the display module 500 and the frame 200 can be assembled first, that is, after the display module 500 and the cover glass 600 are stacked, the plurality of edge strips 230 are sequentially bonded and fixed on the cover glass 600; secondly, the backlight assembly 100 is installed on the rear side of the supporting portion 202; then, the plurality of connecting pieces 300 are connected with the corresponding edge strips 230; finally, the rear shell 400 is connected with the connecting pieces 300 and the frame body 201 at the same time.

[0070] In some embodiments, the connecting piece 300 extends along the length direction of the edge strip 230, and each edge strip 230 can correspond to one or more connecting pieces 300. In order to facilitate assembly, each edge strip 230 in the present embodiment corresponds to one connecting piece 300, so that the number of connecting pieces 300 is less than or equal to the number of edge strips 230, that is, the number of connecting pieces 300 can be one, two, three or four.

[0071] When the number of the connecting pieces 300 is four, the rear shell 400 is connected with the four connecting pieces 300 at the same time. Since the extending directions of the two adjacent connecting pieces 300 are perpendicular to each other, after the rear shell 400 is connected with the four connecting pieces 300, the two adjacent connecting pieces 300 can limit each other, so as to avoid the rear shell 400 from moving relative to the frame 200 after being connected with the connecting pieces 300. That is to say, even if no fixing structure is arranged between the connecting pieces 300 and the side bars 230, the rear shell 400, the four connecting pieces 300 and the four side bars 230 can still form a stable whole.

[0072] In some embodiments, when the number of the connecting pieces 300 is less than the number of the side bars 230, the number of the connecting pieces 300 can be one, two or three, so that the manufacturing cost of the display device 10 is relatively low. The rear shell 400 includes a first side and a second side. The first side is detachably connected with the connecting pieces 300, and the second side is detachably connected with the frame 200. For example, the second side can be connected with the frame 200 through a threaded fastener (not shown), so that the connection stability is relatively high and the rear shell 400 is easy to disassemble and assemble.

[0073] For example, when the display device 10 has three connecting pieces 300, the rear shell 400 has three first sides and one second side.

[0074] When the display device 10 includes three connecting pieces 300, the three connecting pieces 300 can be arranged at any position of the display device 10, for example, the three connecting pieces 300 are arranged at the left side M, the ground side Y and the right side N of the display device 10 respectively. In order to optimize the appearance of the display device 10, the three connecting pieces 300 can also be arranged at the left side M, the sky side X and the right side N of the display device 10 respectively. In this way, the second side of the rear shell 400 is located at the ground side Y of the display device 10, and the threaded fasteners between the rear shell 400 and the connecting pieces 300 are located at the ground side Y of the display device 10, so that the threaded fasteners between the rear shell 400 and the connecting pieces 300 are avoided from being exposed in the field of view of the user, and the appearance of the display device 10 is optimized.

[0075] Meanwhile, when the number of the connecting pieces 300 is less than the number of the side bars 230, the rear shell 400 is connected with the connecting pieces 300 and the frame 200 at the same time. Even if no fixing structure is arranged between the clamping protrusions 310 and the clamping portions 210, the rear shell 400 can also be avoided from moving relative to the frame 200 after being connected with the connecting pieces 300, that is, the rear shell 400, the connecting pieces 300 and the side bars 230 form a stable whole.

[0076] In some embodiments, the rear shell 400 includes a rear shell body 410, and the rear shell body 410 is detachably connected with the connecting pieces 300. Correspondingly, the rear shell body 410 is provided with a plurality of through holes through which the threaded fasteners pass.

[0077] The rear shell 400 further comprises a folded edge 420, which forms an angle with the rear shell body 410. Depending on the relative position between the folded edge 420 and the frame body 201, the angle between the folded edge 420 and the rear shell body 410 can be an acute angle, an obtuse angle or a right angle.

[0078] In some embodiments, the frame body 201 is generally perpendicular to the rear shell body 410, and the angle between the folded edge 420 and the rear shell body 410 is a right angle (as shown in FIG. 4B), i.e. the folded edge 420 is perpendicular to the rear shell body 410. In this case, the folded edge 420 can be attached to the inner side of the frame body 201. Figure 3

[0079] It can be understood that the folded edge 420 is arranged at the second side of the rear shell 400, so that the folded edge 420 is detachably connected to the frame 200. In this way, the first side of the rear shell 400 is connected to the plurality of connecting members 300, and the second side of the rear shell 400 is connected to the frame body 201, so that the rear shell 400, the connecting members 300 and the frame 200 are connected into a stable whole.
