[0041] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0042] It should be noted that when an element is referred to as being "fixed to" or "disposed on" another element, it can be directly on the other element or indirectly on the other element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or indirectly connected to the other element.

[0044] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of this application, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0045] The display module mentioned in this application includes a backlight module and a display module. The "display module" usually mainly includes a cover plate (CL), a touch panel (TP), a thin film transistor (TFT) and a driving circuit.

[0046] The backlight module and the display module in the embodiment of the present application are fixed by bonding. Specifically, double-sided adhesive tape may be provided on the side of the backlight module close to the display module, double-sided adhesive tape may be provided on the side of the display module close to the backlight module, or double-sided adhesive tape may be provided on both the side of the display module close to the backlight module and the side of the backlight module close to the display module.

[0047] Please also read Figures 1 to 4 , the assembly jig of the display module provided in the embodiment of the present application is now described. The assembly jig includes a mounting frame 3, a base 5 and a support member 4. The mounting frame 3 is provided with a first positioning groove 30 and a second positioning groove 31. The first positioning groove 30 is used to accommodate and limit the backlight module 100 in the horizontal direction. The second positioning groove 31 is used to accommodate and limit the display module 200 in the horizontal direction. When the backlight module 100 is placed in the first positioning groove 30 and the display module 200 is placed in the second positioning groove 31, the backlight module 100 and the display module 200 are arranged at intervals. The base 5 is arranged on a side of the mounting frame 3 having the first positioning groove 30, and the base 5 is movably connected to the mounting frame 3 along the first direction. The support member 4 is arranged on a side of the base 5 close to the mounting frame 3. In the process of the mounting frame 3 and the base 5 moving close to each other along the first direction, the support member 4 can support the backlight module 100 and limit the backlight module 100 from moving toward the side close to the base 5.

[0048] The mounting frame 3 is a hollow frame structure, and the first positioning groove 30 is located on the side of the second positioning groove 31 close to the base 5. Therefore, when the backlight module 100 is placed in the first positioning groove 30 and the display module 200 is placed in the second positioning groove 31, the backlight module 100 is located on the side of the display module 200 close to the base 5. The support member 4 can be inserted into the mounting frame 3, so when the mounting frame 3 moves along the first direction close to the base 5, the support member 4 can support the backlight module 100.

[0049] The mounting frame 3 is provided with a first positioning groove 30 and a second positioning groove 31. The backlight module 100 is placed in the first positioning groove 30, and the display module 200 is placed in the second positioning groove 31. The backlight module 100 is spaced apart from the display module 200, so that the backlight module 100 and the display module 200 can be positioned in the horizontal direction and can avoid the backlight module 100 and the display module 200 from being immediately attached during the placement process. After ensuring that the backlight module 100 and the display module 200 are placed stably, the backlight module 100 and the display module 200 are driven by an external force. The mounting frame 3 approaches the base 5. Through the cooperation between the mounting frame 3 and the base 5, it can be ensured that the mounting frame 3 accurately moves in a straight line along the first direction. During the movement, the display module 200 and the backlight module 100 follow the movement until the backlight module 100 contacts the support member 4. The support member 4 restricts the backlight module 100 from continuing to move toward the side close to the base 5, while the display module 200 continues to move with the mounting frame 3, and then the display module 200 and the backlight module 100 approach each other until they are fitted together, thereby realizing the assembly of the display module.

[0050] Compared with the prior art, the assembly fixture of the display module provided in the present application uses the mounting frame 3 to simultaneously position the display module 200 and the backlight module 100, and can separate the backlight module 100 from the display module 200. After ensuring that the backlight module 100 and the display module 200 are stably placed, the mounting frame 3 is driven to move toward the base 5. Through the cooperation between the mounting frame 3 and the base 5, it is possible to ensure that the mounting frame 3 can accurately move in a straight line along the first direction. The supporting member 4 can limit the movement of the backlight module 100 toward the direction close to the base 5, so that the display module 200 can be fitted with the backlight module 100, and the precise positioning and assembly of the display module is achieved, thereby improving the assembly accuracy and ensuring the yield of the product.

[0051] In another embodiment of the present application, please refer to Figures 4 to 7 There is an acting force between the mounting frame 3 and the base 5, and the acting force is used to drive the mounting frame 3 to move toward the side away from the base 5. Therefore, there is a first gap D1 between the mounting frame 3 and the base 5, and the first gap D1 can drive the mounting frame 3 to move toward the base 5 under the action of an external force during assembly, so as to achieve the display module 200 and the backlight module 100 to be close and fixed by bonding.

[0052] It should be noted that: when the backlight module 100 is placed in the first positioning groove 30 and the display module 200 is placed in the second positioning groove 31, the backlight module 100 and the display module 200 have a second gap D2. In order to ensure that the display module 200 can move toward the backlight module 100 to fit and adhere to the backlight module 100 during the movement of the mounting frame 3 toward the base 5, the first gap D1 and the second gap D2 must satisfy the relationship that the first gap D1 is larger than the second gap D2.

[0053] In another embodiment of the present application, please continue to refer to Figures 3 to 6 , the first gap D1 is larger than the second gap D2, when the mounting frame 3 moves along the first direction toward the side close to the base 5, the display module 200 moves synchronously with the mounting frame 3, and the support member 4 limits the movement of the backlight module 100. When the display module 200 moves by the distance of the second gap D2, the display module 200 is attached to the backlight module 100. At this time, the display module 200 and the mounting frame 3 are continuously driven to move under the action of external force, squeezing the double-sided adhesive 300 between the display module 200 and the backlight module 100, so that the display module 200 and the backlight module 100 are tightly attached.

[0054] In another embodiment of the present application, please refer to Figure 2 and Figure 8 A first elastic member 50 is provided between the mounting frame 3 and the base 5 , and the first elastic member 50 abuts against between the mounting frame 3 and the base 5 , and the acting force is the elastic force of the first elastic member 50 .

[0055] By arranging the first elastic member 50 between the mounting frame 3 and the base 5, the first elastic member 50 is used to make an elastic force between the mounting frame 3 and the base 5, and the elastic force drives the mounting frame 3 to move toward the side away from the base 5, so that there is a first gap D1 between the mounting frame 3 and the base 5, and the distance of the first gap D1 can be reduced by squeezing the first elastic member 50 under the action of external force, thereby ensuring that the mounting frame 3 can be driven to move toward the base 5 under the action of external force during assembly, so that the display module 200 and the backlight module 100 are close to each other and are glued and fixed. In addition, the elastic force of the first elastic member 50 can also automatically reset the mounting frame 3 after assembly is completed.

[0056] In another embodiment of the present application, the first elastic member 50 may be a spring, an elastic rubber member, an elastic silicone member, a metal spring, etc. In this embodiment, the first elastic member 50 is a spring.

[0057] In other embodiments, a magnetic component with the same magnetism is provided between the mounting frame 3 and the base 5, and the acting force is the repulsive force of the magnetic component. Specifically, a first magnetic component is fixed on the side of the mounting frame 3 close to the base 5, and a second magnetic component is fixed on the side of the base 5 close to the mounting frame 3. The first magnetic component and the second magnetic component are arranged side by side in the first direction and have the same magnetism. As a result, there is a repulsive force between the mounting frame 3 and the base 5, and the repulsive force drives the mounting frame 3 to move toward the side away from the base 5, so that there is a first gap D1 between the mounting frame 3 and the base 5, and under the action of an external force, the first magnetic component and the second magnetic component can be forced to approach to reduce the distance of the first gap D1, thereby ensuring that the mounting frame 3 can be driven to move toward the base 5 under the action of an external force during assembly, so as to achieve the display module 200 and the backlight module 100 to be close and glued and fixed. In addition, the repulsive force can also automatically reset the mounting frame 3 after the assembly is completed.

[0058] In another embodiment of the present application, please refer to Figure 2 and Figure 8 A limiting column 32 is provided on the mounting frame 3, and a limiting hole 51 is provided on the base 5. One end of the limiting column 32 passes through the first elastic member 50 along the first direction and is inserted into the limiting hole 51.

[0059] The limiting column 32 is passed through the first elastic member 50. During the extension and retraction of the first elastic member 50, the limiting column 32 limits and guides the first elastic member 50 to prevent the first elastic member 50 from tilting. The limiting column 32 is movably inserted into the limiting hole 51 to ensure that the mounting frame 3 can move relative to the base 5 in the first direction. At the same time, the limiting hole 51 also guides the limiting column 32.

[0060] In another embodiment of the present application, please continue to refer to Figure 2 The base 5 is provided with a guide assembly 52, which is used to move the mounting frame 3 along the first direction. This ensures that the mounting frame 3 will not shift in other directions when moving, and can only accurately move in a straight line along the first direction, thereby ensuring the assembly accuracy of the display module 200 and the backlight module 100.

[0061] In another embodiment of the present application, please continue to refer to Figure 2 and Figure 8 The guide assembly 52 includes a guide column 520 and a linear bearing 521, and the guide column 520 is arranged on the base 5. The linear bearing 521 is sleeved on the guide column 520 and can slide relative to the guide column 520 in a first direction, and the outer cylinder of the linear bearing 521 is connected to the mounting frame 3. By arranging the guide column 520 on the base 5 and sleeved on the guide column 520, when the mounting frame 3 moves in the vertical direction, rolling friction occurs between the linear bearing 521 and the guide column 520.

[0062] Specifically, the guide column 520 is fixed on the base 5 , the mounting frame 3 is provided with a guide groove 33 , the outer cylinder of the linear bearing 521 is fixed on the guide groove 33 of the mounting frame 3 , and the inner wall of the linear bearing 521 is slidably connected to the guide column 520 .

[0063] In another embodiment of the present application, please refer to Figure 3 and Figure 4 The mounting frame 3 is provided with two sockets 36, one of which is a square socket for limiting the horizontal movement of the backlight module 100, and the other is a long socket for limiting the horizontal rotation of the backlight module 100. Accordingly, the backlight module 100 is provided with two plugs 1001, which can be inserted into the two sockets 36 along the first direction.

[0064] In another embodiment of the present application, see Figure 3 and Figure 4 When the back plate of the backlight module 100 is a die-casting, the plug post 1001 is a conical truncated cone structure, and a support block is also provided on the mounting frame 3. When the backlight module 100 is placed on the mounting frame 3, the plug hole 36 clamps the plug post 1001, and the support block supports the backlight module 100. With this positioning structure, the horizontal displacement gap between the plug post 1001 and the plug hole 36 can be zero, thereby further improving the assembly accuracy of the backlight module 100 and the display module 200.

[0065] In order to ensure that the jack 36 can correspondingly clamp the pin 1001, a third gap D3 is provided between the support member 4 and the backlight module 100. At this time, the backlight module 100 is not supported by the support member 4, so that the jack 36 and the pin 1001 are coaxial in the first direction, thereby accurately positioning the backlight module 100. In addition, it should be supplemented that when the third gap D3 is provided between the support member 4 and the backlight module 100, the first gap D1, the second gap D2 and the third gap D3 must satisfy the relationship that the first gap D1 is greater than the sum of the second gap D2 and the third gap D3. That is, when the mounting frame 3 moves along the first direction toward the side close to the base 5, the backlight module 100 cannot be restricted from moving due to the third gap D3 between the support member 4 and the backlight module 100. Therefore, the display module 200 and the backlight module 100 move synchronously. When the distance of the third gap D3 is moved, the support member 4 begins to contact the backlight module 100 and restricts the backlight module 100 from continuing to move, while the display module 200 and the mounting frame 3 continue to move the distance of the second gap D2, and the display module 200 moves to contact the backlight module 100 to fit together. At this time, the display module 200 and the mounting frame 3 continue to be driven to move under the action of external force, squeezing the double-sided adhesive 300 between the display module 200 and the backlight module 100, so that the display module 200 and the backlight module 100 are tightly adhered.

[0066] In another embodiment of the present application, see Fig. 9 When the back plate of the backlight module 100 is a sheet metal part, the pin 1001 is a cylinder, the socket 36 is a blind hole, the blind end of the socket 36 supports the pin 1001, and a third gap D3 is provided between the backlight module 100 and the support member 4.

[0067] In another embodiment of the present application, see Fig.10 When the back plate of the backlight module 100 is a sheet metal part, the plug post 1001 is a cylindrical structure, and the plug hole 36 is a through hole. Since it is a through hole, it cannot support the plug post 1001, and the backlight module 100 is supported by the support member 4, that is, the third gap D3 is equal to zero.

[0068] In another embodiment of the present application, please refer to Fig.11 and Fig.12 The mounting frame 3 is provided with a clamping block 34 , and the clamping block 34 is provided with a clamping wall 340 for fitting with the side corner of the display module 200 . The clamping wall 340 cooperates with the groove wall of the second positioning groove 31 so that the display module 200 is clamped in the second positioning groove 31 .

[0069] When the traditional assembly jig is used to assemble the backlight module 100 and the display module 200, the dimensional tolerance of the jig groove, the dimensional tolerance of the display module 200, the dimensional tolerance of the pin 1001, the dimensional tolerance of the socket 36, and the tolerance between the pin 1001 and the wall of the jig groove are often involved. These tolerances can cause large deviations between the display module 200 and the backlight module 100 after assembly, resulting in insufficient assembly accuracy.

[0070] In the embodiment of the present application, a tightening block 34 is added to the mounting frame 3, and the display module 200 is placed in the second positioning groove 31. The display module 200 is pressed against the groove wall of the second positioning groove 31 by the tightening block 34, so as to fix the position of the display module 200 and prevent the display module 200 from shaking during the movement. Furthermore, since the display module 200 is pressed against the groove wall of the second positioning groove 31, that is, there is a zero displacement gap between the display module 200 and the groove wall of the second positioning groove 31, the influence of the dimensional tolerance of the second positioning groove 31 of the mounting frame 3 and the dimensional tolerance of the display module 200 on the assembly accuracy is solved, and the assembly accuracy is further improved. If this solution is combined with the above-mentioned conical truncated cone structure of the pin 1001, the assembly accuracy of the display module 200 and the backlight module 100 can be higher, and only the processing deviation of the mounting frame 3 exists.

[0071] In another embodiment of the present application, please refer to Fig.11 and Fig.12The mounting frame 3 is provided with a second elastic member 35, which is connected to the pressing block 34. The second elastic member 35 can drive the pressing block 34 to move along the diagonal direction of the display module 200. Under the action of the second elastic member 35, the pressing block 34 presses against the side corner of the display module 200, and cooperates with the groove wall of the second positioning groove 31 to fix the display module 200.

[0072] In another embodiment of the present application, please continue to refer to Fig.11 and Fig.12 A mounting groove 341 is provided on the pressing block 34 , and one end of the second elastic member 35 extends into the mounting groove 341 , thereby providing a limiting and guiding effect on the extension and retraction of the second elastic member 35 .

[0073] In another embodiment of the present application, the second elastic member 35 may be a spring, an elastic rubber member, an elastic silicone member, a metal spring, etc. In this embodiment, the second elastic member 35 is a spring.

[0074] In another embodiment of this application, please refer to Figure 2 The assembly jig further includes a pressing plate 1 , which is disposed on a side of the mounting frame 3 having the second positioning groove 31 , and the pressing plate 1 can limit the display module 200 from moving relative to the mounting frame 3 along a first direction.

[0075] Specifically, the pressing plate 1 can be connected to an external pressing device, and the external pressing device drives the display module 200 and the mounting bracket 3 to move by applying pressure to the pressing plate 1 .
