Description

Display device

Technical Field

The present invention relates to a display device, and more particularly, to a display device capable of being quickly assembled and disassembled.

Background

The outermost layer of a typical display is a light transmissive cover plate. The transparent cover plate can be adhered to the edge of the back shell through double-sided adhesive tape or other adhesive tapes, or the transparent cover plate can be adhered to the middle frame through double-sided adhesive tape or other adhesive tapes before the middle frame is adhered or locked to the back shell.

However, when the parts in the back shell need to be maintained or replaced, if the transparent cover plate or the middle frame is adhered to the back shell by double-sided tape or other adhesive, the double-sided tape or other adhesive is not easy to disassemble, and the residual adhesive is easily left during disassembly, even causing damage to the articles. If the middle frame is locked and attached to the back shell by the screws, the screws partially protrude out of the back shell, so that the aesthetic feeling of the back shell is affected, and the locking and attaching of the screws are not beneficial to quick disassembly.

An embodiment of the invention discloses a display device, wherein a frame and a back shell of a cover plate are quickly assembled and disassembled, and objects are not easy to damage during assembly and disassembly.

In an embodiment of the invention, a display device includes a back case, a display module, a frame, a cover plate, and at least one engaging member. The back shell comprises at least one first clamping structure and a back plate. The frame is positioned on the back shell. The display module is clamped between the frame and the back shell. The cover plate covers and is fixedly arranged on the frame. The clamping piece is positioned on the frame. The clamping piece comprises a second clamping structure. The second clamping structure can move between a clamping position and a retreating position, and the second clamping structure in the clamping position is abutted against the first clamping structure and positioned between the first clamping structure and the backboard. The second clamping structure positioned at the retreating position is separated from the first clamping structure.

In some embodiments, the back shell has at least one through hole. The clamping piece also comprises an operation part. The operation part is interlocked with the second clamping structure. At least part of the operation part is exposed from the through hole.

In some embodiments, the through hole is formed in the back plate.

In some embodiments, the engaging member further includes at least one shielding portion. The shielding part is interlocked with the operation part. The shielding part and the operating part are arranged along the movable direction of the second clamping structure.

In some embodiments, the operation portion is at least partially located in the through hole. The shielding part is positioned outside the through hole.

In some embodiments, the engaging member further includes a limiting hole. The frame comprises a limit structure. The limiting hole is provided with a hole wall close to the backboard. The limiting structure is at least partially positioned in the limiting hole and abuts against the hole wall.

In some embodiments, the limiting structure tapers in a direction away from the hole wall.

In some embodiments, the engaging member includes a covering portion. The covering part is interlocked with the second clamping structure. The frame is partially located between the cover and the back shell. The cover portion abuts the frame.

In some embodiments, the frame includes at least one engaging member receiving slot and a through hole. The clamping piece accommodating groove is provided with a bottom surface. The through hole is arranged on the bottom surface of the clamping piece accommodating groove. The clamping piece comprises a covering part and at least one protruding part protruding out of the covering part. The cover part is movably positioned in the clamping piece accommodating groove.

In some embodiments, the first engaging structure includes a first contact surface. The second clamping structure comprises a second abutting surface and an inclined surface which are adjacent to each other. The second abutting surface of the second clamping structure abuts against the first abutting surface when the second clamping structure is located at the clamping position, and the inclined surface of the second clamping structure and the first abutting surface when the second clamping structure is located at the clamping position form an acute angle. The inclined surface of the second clamping structure is closer to the first clamping structure than the second abutting surface when the second clamping structure is positioned at the retreating position.

In some embodiments, the display device further comprises a waterproof gasket. The waterproof gasket is abutted between the frame and the back shell.

According to the embodiment, the clamping piece is arranged on the frame, and can be abutted against the first clamping structure of the back shell when in the clamping position and can be separated from the first clamping structure when in the retreating position, so that a user can clamp the clamping piece and the first clamping structure by moving the clamping piece so as to quickly fix the frame and the back shell together; in addition, the user can also make the clamping piece separate from the first clamping structure by moving the clamping piece so as to rapidly release the fixed relation between the frame and the back shell, thereby being beneficial to the user to detach the frame and the back shell. Therefore, the frame and the back shell can be quickly assembled and disassembled, and the object is prevented from being damaged during assembly and disassembly because the frame and the back shell are fixed in a clamping manner.

The above description is merely illustrative of the problems to be solved, the technical means to solve the problems, the effects to be produced, etc., and the specific details of the present invention will be described in the following detailed description and the related drawings.

Detailed Description

In the following description, numerous practical details of embodiments of the invention are set forth in the accompanying drawings, which are for purposes of clarity. However, it will be understood by those skilled in the art that these practical details are not necessary in some embodiments of the present invention and are not, therefore, to be taken as limiting the present invention. Furthermore, for the purpose of simplifying the drawings, some known and conventional structures and elements are shown in the drawings in a simplified schematic manner. In addition, the dimensions of the various elements in the drawings are not drawn to scale for the convenience of the reader.

Fig. 1 is a perspective view of a display device according to an embodiment of the invention. Fig. 2 is an exploded perspective view of the display device of fig. 1. As shown in fig. 1 and 2, the display device includes a cover plate 100, a locking member 200, a frame 300, a display module 400, and a back case 500. The cover plate 100 covers and is fixed to the frame 300. The frame 300 is positioned on the back shell 500. The display module 400 is sandwiched between the frame 300 and the back shell 500, and in practice, the display module 400 may be selectively fixed to the frame 300 or the back shell 500 according to the design. The engaging member 200 is disposed on the frame 300. The back case 500 and the frame 300 are detachably coupled by the engaging member 200. The back case 500 has a receiving space 502, and when the frame 300 is combined with the back case 500, the cover plate 100 may cover the back case 500, thereby closing the receiving space 502 of the back case 500. If the components (such as hard disk, memory or power supply) in the back shell 500 are to be replaced or maintained, the frame 300 can be detached from the back shell 500 to expose the accommodating space 502 of the back shell 500, so as to facilitate the replacement or maintenance of the components in the back shell 500. The fastener 200 disclosed herein can facilitate quick assembly and disassembly of the frame 300 and the back shell 500.

In detail, reference may be made to fig. 3 to 5, wherein fig. 3 illustrates an internal perspective assembly view of the display device viewed from the back side, fig. 4 illustrates an enlarged view of a partial region R1 of fig. 3, and fig. 5 illustrates an enlarged view of the engaging member 200 in the partial region R1 moving to another position. In this embodiment, the back shell 500 includes a back plate 510 and a first engaging structure 530. The engaging member 200 is disposed on the frame 300. The engaging member 200 includes a second engaging structure 210. The second engaging structure 210 shown in fig. 4 is located at an engaging position, and the second engaging structure 210 when located at the engaging position is located between the back plate 510 of the back shell 500 and the first engaging structure 530 and abuts against the first engaging structure 530. The second engaging structure 210 shown in fig. 5 is located at the retracted position, and the second engaging structure 210 located at the retracted position is separated from the first engaging structure 530. The engaging member 200 is at least one-dimensionally movable with respect to the back shell 500, such that the second engaging structure 210 is movable between an engaging position (shown in fig. 4) and a retracted position (shown in fig. 5). Further, the second engaging structure 210 at the engaging position can move away from the first engaging structure 530 (e.g. along arrow D1 shown in fig. 4) to the retracted position, and the second engaging structure 210 at the retracted position can move toward the first engaging structure 530 (e.g. along arrow D2 shown in fig. 5) to the engaging position.

Since the second engaging structure 210 located at the engaging position can abut against one side of the first engaging structure 530 near the back plate 510 (as shown in fig. 4), when the back shell 500 receives the force F1 facing away from the frame 300, the second engaging structure 210 can prevent the first engaging structure 530 from moving, thereby preventing the back shell 500 from being separated from the engaging member 200 due to the force F1, and further, since the engaging member 200 is disposed on the frame 300, when the back shell 500 is engaged with the engaging member 200, the back shell 500 can be prevented from being separated from the frame 300 due to the force F1, thereby achieving the effect of fixing the back shell 500 and the frame 300. Similarly, when the engaging member 200 receives a force F2 facing away from the back plate 510, the first engaging structure 530 can prevent the second engaging structure 210 from moving, so as to prevent the engaging member 200 from being separated from the back shell 500 due to the force F2, and further, since the engaging member 200 is disposed on the frame 300, when the engaging member 200 is engaged with the back shell 500, the frame 300 can be prevented from being separated from the back shell 500 due to the force F2, thereby achieving the effect of fixing the frame 300 and the back shell 500.

On the other hand, since the second engaging structure 210 is separated from the first engaging structure 530 when being located at the retreating position (as shown in fig. 5) and is not located between the first engaging structure 530 and the back plate 510, when the back shell 500 receives the force F1 facing away from the frame 300, the second engaging structure 210 does not block the first engaging structure 530, so that the back shell 500 can be separated from the engaging member 200 under the influence of the force F1, and thus, the frame 300 where the engaging member 200 is located is separated. Similarly, when the engaging member 200 receives the force F2 facing away from the back plate 510, the first engaging structure 530 does not block the second engaging structure 210, so that the engaging member 200 can be separated from the back shell 500 under the influence of the force F2, thereby facilitating the frame 300 where the engaging member 200 is located to be separated from the back shell 500.

In some embodiments, as shown in fig. 4 and 5, the first engagement structure 530 includes a first contact surface 532. The second engaging structure 210 includes a second contact surface 212 and an inclined surface 214. The second abutment surface 212 is contiguous with the inclined surface 214. The second contact surface 212 of the second engaging structure 210 when in the engaging position contacts the first contact surface 532. The inclined surface 214 of the second engaging structure 210 when in the engaged position forms an acute angle θ with the first abutting surface 532, and the inclined surface 214 of the second engaging structure 210 when in the retracted position is closer to the first engaging structure 530 than the second abutting surface 212. In other words, the inclined surface 214 is located at an edge of the second contact surface 212 near the first engaging structure 530 and is inclined in a direction away from the first engaging structure 530. In this way, when the second engaging structure 210 moves toward the first engaging structure 530 along the arrow D2 shown in fig. 5, the inclined surface 214 can reduce the resistance of the second engaging structure 210 moving below the first engaging structure 530, so as to facilitate the engagement between the first engaging structure 530 and the second engaging structure 210. More specifically, in some embodiments, the first engaging structure 530 and the second engaging structure 210 are interference fit, and the inclined surface 214 can reduce the resistance of the first engaging structure 530 and the second engaging structure 210 during the assembling process. In other embodiments, the edge of the first contact surface 532 near the second engaging structure 210 may also be provided with an inclined surface to reduce the resistance of the first engaging structure 530 and the second engaging structure 210 during the assembling process, and in such embodiments, the inclined surface 214 of the second engaging structure 210 may be omitted. The second engaging structure 210 shown in fig. 4 and 5 shows a single inclined surface 214, but the number of inclined surfaces 214 is not limited thereto. For example, in other embodiments, the second engaging structure 210 may also include two inclined surfaces 214, and the two inclined surfaces 214 are respectively located at opposite ends of the second engaging structure 210, and the two inclined surfaces 214 are symmetrical.

In some embodiments, as shown in fig. 4 and 5, the back shell 500 has a through hole H1. The engaging member 200 further includes an operating portion 220. The operation portion 220 is interlocked with the second engaging structure 210. The through hole H1 exposes at least part of the operation portion 220. In this way, the user can insert a finger tip or a tool into the through hole H1 to toggle the operation portion 220, so as to drive the second engaging structure 210 to move between the engaging position and the retracted position. Further, in some embodiments, the through hole H1 has a length parallel to the movable direction of the second engaging structure 210 (e.g. the arrow D1 direction shown in fig. 4 or the arrow D2 direction shown in fig. 5), the operating portion 220 also has a length parallel to the movable direction of the second engaging structure 210, and the length of the through hole H1 is greater than the length of the operating portion 220, so that a user can toggle the operating portion 220 along the arrow D1 direction shown in fig. 4 or the arrow D2 direction shown in fig. 5, thereby driving the second engaging structure 210 to move between the engaging position and the releasing position.

In more detail, when the second engaging structure 210 is located at the engaging position shown in fig. 4, the user can toggle the operating portion 220 along the direction of arrow D1, so as to drive the second engaging structure 210 to move to the retracted position shown in fig. 5 along the direction of arrow D1 and disengage from the first engaging structure 530; in contrast, when the second engaging structure 210 is located at the retracted position shown in fig. 5, the user can toggle the operating portion 220 along the direction of arrow D2, so as to drive the second engaging structure 210 to move to the engaging position shown in fig. 4 along the direction of arrow D2, and move between the first engaging structure 530 and the back plate 510 and abut against the first engaging structure 530. Because the user can control the engagement between the engaging member 200 and the back shell 500 only by pulling the operating portion 220, the design can facilitate the user to quickly and conveniently assemble and disassemble the display device.

In some embodiments, the operation portion 220 is at least partially located in the through hole H1, so that a user can toggle the operation portion 220. Further, since at least a portion of the operation portion 220 is disposed in the through hole H1, the user can touch and toggle the operation portion 220 without passing a finger tip or a tool through the entire through hole H1, thereby facilitating the user to operate the engaging member 200.

In some embodiments, as shown in fig. 4 and 5, the engaging member 200 further includes a shielding portion 230. The shielding portion 230 is interlocked with the operation portion 220, and the shielding portion 230 and the operation portion 220 are arranged along a movable direction (for example, an arrow D1 direction shown in fig. 4 or an arrow D2 direction shown in fig. 5) of the second engaging structure 210. In this way, the shielding portion 230 can shield the through hole H1, so as to prevent foreign objects (e.g., dust) from entering the display device by mistake through the through hole H1. In some embodiments, the shielding portion 230 may be omitted, and after the display device is assembled, a user may attach a shielding object (such as an adhesive tape or other decoration) to the exposed portion of the through hole H1, and tear the adhesive tape to toggle the operation portion 220 when the display device needs to be disassembled.

In some embodiments, when the display device is in use, the second engaging structure 210 is located at the engaging position to prevent the display device from being detached, and when the display device needs to be detached, the second engaging structure 210 is moved to the retreating position to facilitate the detachment of the display device. Since the service time of the display device is generally longer than the detachment time of the display device, when the second engaging structure 210 is located at the engaging position, the area of the shielding portion 230 exposed to the through hole H1 is preferably larger than the area of the shielding portion 230 exposed to the through hole H1 when the second engaging structure 210 is located at the retracting position, so that the shielding portion 230 can cover a larger range of the through hole H1 when the second engaging structure 210 is located at the engaging position. To achieve such a design, in some embodiments, the operation portion 220 and the shielding portion 230 are arranged along the direction in which the engagement position moves to the retracted position (i.e., the direction of arrow D1), and the shielding portion 230 is located outside the through hole H1. In this way, when the second engaging structure 210 moves along the arrow D1 direction, the area of the shielding portion 230 exposed to the through hole H1 can be reduced; in contrast, when the second engaging structure 210 moves along the direction of the arrow D2, the area of the shielding portion 230 exposed to the through hole H1 can be increased, so that the shielding portion 230 can effectively shield the through hole H1 when the display device is in use.

In other embodiments, if the shielding portion 230 is used to shield the through hole H1 of the second engaging structure 210 at the retracted position, the operation portion 220 and the shielding portion 230 may be arranged along the direction of the retracted position toward the engaging position (i.e., the direction of arrow D2), and the shielding portion 230 is located outside the through hole H1, so that when the second engaging structure 210 moves along the direction of arrow D2, the area of the shielding portion 230 exposed to the through hole H1 may be reduced; in contrast, when the second engaging structure 210 moves along the direction of arrow D1, the area of the shielding portion 230 exposed to the through hole H1 may be increased, so that the shielding portion 230 may effectively shield the through hole H1 when the second engaging structure 210 moves along the direction of arrow D1 to the retracted position.

In some embodiments, as shown in fig. 4 and 5, the through hole H1 is formed in the back plate 510 of the back shell 500. Further, the back plate 510 has an inner surface 512 and an exposed surface 514. The inner surface 512 is opposite the exposed surface 514. The through hole H1 penetrates the inner surface 512 and the exposed surface 514. The operation portion 220 extends into the through hole H1 from above the inner surface 512 of the back plate 510, so that a user can insert a finger tip or a tool into the through hole H1 of the back plate 510 from outside the exposed surface 514 of the back plate 510 to toggle the operation portion 220. In some embodiments, the shielding portion 230 is located on the inner surface 512 of the back plate 510 and does not extend into the through hole H1, so as to prevent the shielding portion 230 from interfering with the wall of the through hole H1 when the engaging member 200 moves.

In some embodiments, as shown in fig. 2, the back shell 500 further includes a side plate 520. The side plate 520 is disposed on the back plate 510, and the side plate 520 and the back plate 510 together define a receiving space 502 for receiving the display module 400 and other components (such as a hard disk, a memory or a power supply). The first engaging structure 530 may protrude from an inner surface (i.e., a surface facing the accommodating space 502) of the side plate 520. When the frame 300 is combined with the back shell 500, the frame 300 abuts against the surface of the side plate 520 away from the back plate 510. In some embodiments, the through hole H1 may be formed in the side plate 520, rather than the back plate 510. The operation portion 220 may extend into the through hole H1 of the side plate 520. In this way, the user can insert a fingertip or a tool into the through hole H1 of the side plate 520 from the outside of the side plate 520 to toggle the operation part 220. In other words, in some embodiments, the user can operate the engaging member 200 from outside the back plate 510, while in some embodiments, the user can operate the engaging member 200 from outside the side plate 520.

Fig. 6 is a perspective view illustrating the engaging member 200 combined with the frame 300, fig. 7 is an enlarged view of the partial region R2 of fig. 6 from another view, and fig. 8 is an enlarged view of the partial region R2 of fig. 6 when the engaging member 200 moves to another position. Referring to fig. 6 to 8, in some embodiments, the frame 300 includes a fastener receiving slot 302 and a through hole H2. The fastener receiving recess 302 includes a bottom surface 304. The through hole H2 is formed in the bottom surface 304 of the engaging member accommodating groove 302. The engaging member 200 includes a protruding portion 202 and a covering portion 204. The protruding portion 202 protrudes from the covering portion 204. The cover 204 is movably positioned in the engaging piece accommodating groove 302. The protruding portion 202 penetrates through the through hole H2, and the protruding portion 202 is movable with respect to the through hole H2. The second engaging structure 210 is located on the protruding portion 202. Further, the cover 204 is interlocked with the protrusion 202, and the cover 204 is at least one-dimensionally movable along the arrow D3 shown in fig. 6 relative to the engaging member receiving slot 302, such that the cover 204 drives the protrusion 202 to move along the arrow D1 in fig. 7 and the second engaging structure 210 to move to the retracted position; or the covering portion 204 drives the protruding portion 202 to move along the direction of arrow D2 in fig. 8, and drives the second engaging structure 210 to move to the engaging position.

Specifically, in some embodiments, as shown in fig. 7 and 8, the width of the protruding portion 202 in the direction parallel to the arrow D1 or D2 is smaller than the width of the through hole H2 in the direction parallel to the arrow D1 or D2, so that the protruding portion 202 can move along the arrows D1 and D2, thereby facilitating the movement of the second engaging structure 210 between the engaging position and the retracted position. In some embodiments, the thickness of the protruding portion 202 and the thickness of the through hole H2 may be equal, so that the protruding portion 202 moves in one dimension, and the second engaging structure 210 is ensured to be engaged with the first engaging structure 530 of the back shell 500 (as shown in fig. 4).

In some embodiments, as shown in fig. 6, the engaging member receiving groove 302 includes a limiting wall 306. The limiting wall 306 is erected on the bottom surface 304 of the engaging member receiving groove 302, and the limiting wall 306 extends along the movable direction (i.e. the arrow D3 direction) of the covering portion 204. The cover 204 of the engaging member 200 covers the bottom 304 of the engaging member accommodating groove 302 and abuts against the limiting wall 306. In this way, the limiting wall 306 can help to constrain the cover 204 to move along the direction of arrow D3 in one-dimensional manner, so as to ensure that the second engaging structure 210 can engage with the first engaging structure 530 of the back shell 500 (as shown in fig. 4).

It should be noted that, in some embodiments, when the cover 204 abuts against the limiting wall 306 such that the movable path of the cover 204 is limited, the thickness of the protrusion 202 may be smaller than the thickness of the through hole H2, and the limiting wall 306 is used to constrain the fastener 200 to move unidimensionally along the direction of the arrow D3. In some embodiments, when the thickness of the protruding portion 202 is equal to the thickness of the through hole H2, the engaging member receiving groove 302 may not have the limiting wall 306, or the covering portion 204 may not abut against the limiting wall 306, and the engaging member 200 is constrained to move unidimensionally along the arrow D3 direction by matching the thicknesses of the protruding portion 202 and the through hole H2. In some embodiments, when the cover 204 abuts against the limiting wall 306, the thickness of the protruding portion 202 and the thickness of the through hole H2 may be equal, so as to further restrict the one-dimensional movement of the engaging member 200 along the direction of the arrow D3.

In some embodiments, as shown in fig. 7 and 8, the engaging member 200 further includes a limiting hole 240. The retaining hole 240 has a hole wall 242 adjacent to the back plate 510 (see fig. 4 or 5). The hole wall 242 is also the inner wall of the limiting hole 240 farthest from the covering portion 204. The frame 300 also includes a spacing structure 310. The limiting structure 310 is at least partially located in the limiting hole 240 and abuts against the hole wall 242 of the limiting hole 240. Further, when the user inserts the engaging member 200 into the engaging member receiving groove 302 along the direction of arrow D4 shown in fig. 6, the protrusion 202 of the engaging member 200 enters the through hole H2 and interferes with the limiting structure 310, and when the user continues to apply the force along the direction of arrow D4, the frame 300, the protrusion 202 or both slightly deforms to make the limiting structure 310 enter the limiting hole 240 and abut against the hole wall 242, so that the limiting structure 310 can prevent the engaging member 200 from being separated from the frame 300 along the direction opposite to the direction of arrow D4 through the abutting relationship with the hole wall 242, thereby facilitating the engaging member 200 to be stably located in the engaging member receiving groove 302.

In some embodiments, the frame 300 is more flexible than the engaging member 200, such that the frame 300 can be deformed due to the force during the assembly process of the engaging member 200 and the frame 300, so as to allow the protrusion 202 to cross the limiting structure 310 to enable the limiting structure 310 to enter the limiting hole 240, so as to clamp the engaging member 200 and the frame 300; in contrast, during the process of disassembling the engaging member 200 from the frame 300, the frame 300 may be deformed due to the force, so as to allow the limiting structure 310 to leave the limiting hole 240, and facilitate the protrusion 202 to leave the through hole H2 of the frame 300, so as to disassemble the engaging member 200 from the frame 300. For example, the material of the engaging member 200 may be metal, and the material of the frame 300 may be plastic.

In some embodiments, as shown in fig. 7 and 8, the limiting structure 310 is tapered along a direction away from the hole wall 242 of the limiting hole 240. In other words, the limiting structure 310 is gradually widened along a direction away from the engaging member receiving groove 302, such that the limiting structure 310 has an inclined surface 312. In this way, when the user inserts the engaging member 200 into the engaging member receiving groove 302 along the arrow D4 shown in fig. 6, the protruding portion 202 can move along the inclined surface 312 to cross the limiting structure 310, that is, the inclined surface 312 can reduce the resistance of the protruding portion 202 crossing the limiting structure 310, so as to facilitate the assembly of the engaging member 200 and the frame 300.

In some embodiments, the operation portion 220 and the shielding portion 230 are located on the protruding portion 202, and the operation portion 220, the shielding portion 230 and the second engaging structure 210 protrude from the same side of the protruding portion 202. In some embodiments, the protruding portion 202, the second engaging structure 210, the operating portion 220, the shielding portion 230 and the covering portion 204 are interlocked. In other words, when the operation portion 220 is pushed, the protruding portion 202, the second engaging structure 210, the shielding portion 230 and the covering portion 204 move together. For example, the engaging member 200 may be an integrally formed structure, such as: an integrally formed metal shaft.

In some embodiments, a fastener 200 may include a plurality of second engaging structures 210, and the back shell 500 may also include a corresponding plurality of first engaging structures 530. Because the second engaging structures 210 are interlocked with the operation portion 220, a user can engage or disengage the second engaging structures 210 with or from the corresponding number of first engaging structures 530 by pulling the single operation portion 220, and compared with the conventional method of locking with a large number of screws, the present embodiment can greatly shorten the assembly/disassembly time of the display device.

In some embodiments, as shown in fig. 2, the frame 300 has a through opening 308. The cover plate 100 includes a transparent region 110 and an opaque region 120. The opaque region 120 surrounds the transparent region 110. The visible area of the display module 400 is exposed through the opening 308 and the transparent area 110. In other words, the visual area of the display module 400 is located right behind the through opening 308 and the light-transmitting area 110, so that a user can watch the display screen of the visual area of the display module 400 from the front of the cover plate 100. In some embodiments, the display module 400 may be a liquid crystal display module, an electrophoresis display module or an organic light emitting diode display module, but the invention is not limited thereto. In some embodiments, the cover 100 may be a glass cover or a touch module, but the invention is not limited thereto. When the cover plate 100 is a touch module, the light-transmitting region 110 may include light-transmitting conductive materials such as Indium Tin Oxide (ITO), indium zinc Oxide (Indium Zinc Oxide, IZO), nano silver or metal mesh (metal mesh), but the invention is not limited thereto. When the cover 100 is a touch module, the opaque material of the opaque region 120 can shield the peripheral trace of the transparent conductive material of the transparent region 110. For example, the opaque region 120 may comprise ink, but the invention is not limited thereto.

In some embodiments, the display module 400 and the frame 300 may be fixed by locking or adhering, or the display module 400 may be fixed to the back shell 500 by locking or buckling, but the invention is not limited thereto. In some embodiments, the cover plate 100 and the frame 300 may be fixed by locking or adhering, but the invention is not limited thereto.

Fig. 9 is a partial cross-sectional view of a display device according to another embodiment of the invention. As shown in fig. 9, the difference between the present embodiment and the foregoing embodiment is at least that: the display device of the present embodiment further includes a waterproof gasket 600. The waterproof gasket 600 is abutted between the frame 300 and the back case 500, and prevents moisture in the external environment from penetrating into the display device from the gap between the frame 300 and the back case 500. In some embodiments, the frame 300 is partially located between the cover 204 and the back shell 500, and the cover 204 abuts against the bottom 304 of the engaging member receiving groove 302 of the frame 300. Since the second engaging structure 210 in the engaging position is the first engaging structure 530 abutting against the back shell 500 above it, and the covering portion 204 is the bottom surface 304 abutting against the engaging member receiving groove 302 of the frame 300 below it, the engaging member 200 can facilitate clamping the frame 300 and the back shell 500, thereby facilitating clamping the waterproof gasket 600 between the frame 300 and the back shell 500, so as to further enhance the waterproof capability.

While the present invention has been described with reference to the embodiments, it will be understood by those skilled in the art that various changes and modifications may be made without departing from the spirit and scope of the invention, and it is intended that the scope of the invention be limited only by the appended claims.
