The illustrative representations of the above terms do not necessarily refer to the same embodiment or example.

[0039] The technical solutions of this application will be clearly and completely described below with reference to the accompanying drawings of the embodiments in this specification. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments in this application specification, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application specification.

[0040] With the rapid development of display technology, people have higher and higher requirements for the mechanical strength of display modules. As an effective test method for detecting the mechanical strength of display modules, the drop ball test has become an indispensable part of the display module production process.

[0041] During the ball drop test, the display module needs to be placed on a ball drop platform and secured with fixing components. Currently, fixing components of corresponding sizes are usually manufactured for different display modules. This results in poor versatility of fixing components in the display module testing fixture. Different fixing components need to be prepared for different sizes of display modules, leading to high fixture investment costs and low utilization rate of fixing components.

[0042] Based on this, this application provides a new fixing component with high versatility and high utilization. The number of corner portions and extensions forming the fixing component can be determined by the size of the display module, and then the determined number of corner portions and extensions are used to enclose and form a frame structure that can fix the display module. In this way, the testing needs of display modules of various sizes can be met, and the utilization rate of test fixtures can be improved.

[0043] Specifically, as an optional implementation of the disclosure in this application, an embodiment of this application provides a fixed component. Figure 1This is a schematic diagram of the structure of a fixing component provided in one embodiment of this application. Figure 1 As shown, the fixing component may include multiple corner portions M and multiple extension portions N; the multiple corner portions M and multiple extension portions N enclose and form a frame structure L for fixing the display module.

[0044] Among them, such as Figure 2 As shown, the corner portion M includes a first corner structure M1 and a second corner structure M2 connected to each other, with the extension direction of the first corner structure M1 intersecting the extension direction of the second corner structure M2. At least one extension N is spliced ​​between the two first corner structures M1, and / or, at least one extension N is spliced ​​between the two second corner structures M2.

[0045] For example, such as Figure 1 As shown, the display module A is rectangular, with four corner parts M and two extension parts N enclosing a frame structure L. The extension parts N are located between the two first corner parts M1. The frame structure L has a fixing function, which can fix the display module A in the hollow frame.

[0046] To facilitate assembly and disassembly, the frame structure L can be made of magnetic material, so that multiple corner parts M and multiple extension parts N can be magnetically attracted and spliced ​​together to form the frame structure L.

[0047] Of course, this application is not limited to this. In some other embodiments, the frame structure L can also be made of a non-magnetic material. When the frame structure L is made of a non-magnetic material, magnetic splicing blocks can be provided at the connection between each extension N and the corner M to achieve magnetic attraction and splicing between the components through the splicing blocks. Alternatively, multiple extensions N and multiple corners M can be connected in other detachable ways.

[0048] In this way, by using multiple corner parts M and multiple extension parts N, it can be enclosed according to the different sizes of different display modules, so as to fix display modules of different sizes during the ball drop test, thereby meeting the testing needs of display modules of various sizes and effectively improving the utilization rate of the fixture.

[0049] In application, the first corner structure M1 and the second corner structure M2 can be fixedly connected.

[0050] The first corner structure M1 and the second corner structure M2 can be corner structures of the same size or corner structures of different sizes.

[0051] Specifically, the first corner structure M1 and the second corner structure M2 can be used to fix the adjacent sides of the display module respectively. Correspondingly, after the first corner structure M1 and the second corner structure M2 are fixedly connected, they form a corner part M. The shape of the corner part M is adapted to the shape of the corner part of the fixed display module.

[0052] like Figure 1 As shown, taking the display module A to be tested as a rectangle as an example, the frame structure L can be an L-shaped frame structure. The extension direction of the first corner structure M1 is perpendicular to the extension direction of the second corner structure M2. Based on the size of the display module to be tested, the number of the first corner structure M1, the second corner structure M2, and the extension N can be determined. Using the determined number of first corner structures M1, second corner structures M2, and extensions M, a fixing component that can secure the display module to be tested is formed. Specifically, the L-shaped frame structure is suitable for modules with right-angled edges, and can also be used for modules with curved edges.

[0053] It should be noted that this application only uses the fixed connection of the first corner structure M1 and the second corner structure M2 as an example for illustration, but this application is not limited to this. In some other embodiments, the first corner structure K1 and the second corner structure K2 can also be integrally formed or detachably connected.

[0054] It should be noted that the embodiments of this application are only illustrated by the example of a fixing component including multiple corner portions M and multiple extension portions N. However, this application is not limited to this. In some other embodiments, the fixing component may also include only multiple corner portions M, which together form a frame structure L for fixing the display module. The number of corner portions M can be determined based on the shape of the corner portions and the size of the display module. For example, as... Figure 2 As shown, the fixing component may include four corner parts M, which together form a frame structure L for fixing the rectangular display module.

[0055] In some embodiments of this application, such as Figure 3 As shown, the extension N includes at least a first extension structure N1 and a second extension structure N2. The extension direction of the first extension structure N1 and the extension direction of the second extension structure N2 are the same, and the first extension structure N1 and the second extension structure N2 are telescopically connected. In application, the first extension structure N1 and the second extension structure N2 of the same extension N are located on the same side of the display module.

[0056] The first extension structure N1 and the second extension structure N2 can be the same extension structure or different extension structures.

[0057] The first extension structure N1 and the second extension structure N2 are scalably connected. That is, the extension N formed by the first extension structure N1 and the second extension structure N2 has scalable characteristics. Therefore, after the frame structure L is formed by enclosing multiple corner portions M and multiple extension portions N, the size of the frame structure L can be adjusted using the scalable characteristics of the extension portions N to accommodate display modules of different sizes. This reduces the number of times the frame structure L is disassembled and assembled, saving testing time. Furthermore, the assembled fixed assembly can meet the testing requirements of display modules of various sizes, thereby further improving the versatility of the display module testing fixture.

[0058] Specifically, the number of first extension structures N1 and second extension structures N2, as well as their splicing order, can be set according to actual needs and are not specifically limited here. For example, the extension N can be composed of a first extension structure N1 and a second extension structure N2 that are retractably connected, or it can be composed of two first extension structures N1 and a second extension structure N2 that are retractably connected, and so on.

[0059] To better realize the expansion and contraction characteristics between the first extension structure N1 and the second extension structure N2, such as Figure 3 , Figure 4 and Figure 5 As shown, the extension N may also include a fixing plate N3, and the first extension structure N1 and the second extension structure N2 are slidably disposed on the fixing plate N3 along the extension direction of the first extension structure N1.

[0060] Specifically, such as Figure 4 As shown, the fixed plate N3 is slidably connected to the first extension structure N1 and the second extension structure N2 via the first sliding rail g1 and the second sliding rail g2, respectively. The first extension structure N1 slides along the first sliding rail g1 in its extension direction, and the second extension structure N2 slides along the second sliding rail g2 in the same direction. This sliding of the first extension structure N1 on the first sliding rail g1 and the second extension structure N2 on the second sliding rail g2 enables a retractable connection between the two structures. When the first extension structure N1 and the second extension structure N2 slide towards each other, the extension portion N shrinks; when they slide away from each other, the extension portion N extends.

[0061] To prevent unexpected changes in the adjusted dimensions of the extension N, and to ensure the stability of the connection between the first extension structure N1, the second extension structure N2, and the fixed plate N3, such as... Figure 3 and Figure 5 As shown, the fixing plate N3 is also provided with a third fixing member N4 and a fourth fixing member N5.

[0062] The third fastener N4 is configured to fix the first extension structure N1 to the fixing plate N3 at any sliding position of the first extension structure N1; the fourth fastener N5 is configured to fix the second extension structure N2 to the fixing plate N3 at any sliding position of the second extension structure N2.

[0063] Specifically, such as Figure 5 As shown, multiple fixing holes q can be provided on the side of the fixing plate N3 away from the inner side of the frame structure L. The third fixing member N4 can fix the first extension structure N1 to the fixing plate N3 through the fixing holes q at the corresponding positions to prevent the first extension structure N1 from continuing to slide on the first sliding track g1. Similarly, the fourth fixing member N5 can fix the second extension structure N2 to the fixing plate N3 through the fixing holes q at the corresponding positions to prevent the second extension structure N2 from continuing to slide on the second sliding track g2.

[0064] In application, both the third fastener N4 and the fourth fastener N5 can be fixing screws.

[0065] Of course, this application is not limited to this. In some other embodiments, the third fastener N4 and the fourth fastener N5 may also be other devices that can respectively fix the first extension structure N1 and the second extension structure N2 on the fixing plate N3, such as rivets.

[0066] like Figure 6 The diagram shows a frame structure L formed by connecting four corner sections M and four extension sections N. By adjusting the sliding positions of the first extension structure N1 and the second extension structure N2 on the fixed plate N3, the side length of the frame structure L can be adjusted to accommodate display modules of various sizes. In practical applications, the specific number of corner sections M and extension sections N required to form the frame structure L can be set according to actual needs and is not limited here. For example, Figure 7 The diagram shows a frame structure L formed by four corner sections M and six extension sections N.

[0067] In some embodiments of this application, such as Figure 2 , Figure 3 and Figure 4 As shown, at least one support structure T is provided on the inner side of the frame structure L. By providing the support structure T on the inner side of the frame structure L, the frame structure L can support the display module through the support structure T, thereby preventing the display module from falling out of the hollow area of ​​the frame structure L during the fixing process.

[0068] Since the drop ball test assesses the drop resistance of the display module, to avoid the support of the tray structure T affecting the testing of the display module, such as... Figure 8As shown, the pallet structure T may include a fixed pallet T1, and the extension length of the fixed pallet toward the center of the frame structure L is adjustable.

[0069] Preferably, each side of the frame structure L is provided with at least one support plate structure T. It should be understood that each side of the frame structure L refers to each side of the inner side of the frame structure L.

[0070] Specifically, a support structure T may be provided on the first side of the first corner structure M1, the second corner structure M2, the first extension structure N1, and / or the second extension structure N2. The first side refers to the side of the first corner structure M1, the second corner structure M2, the first extension structure N1, and the second extension structure N2 that is located inside the frame structure L.

[0071] To improve the stability of the pallet structure T, the pallet structure T may also include a first fastener T2 disposed on the frame structure.

[0072] The fixed support plate T1 is embedded inside the frame structure L and is telescopic in the embedding direction; that is, the fixed support plate T1 has the characteristic of telescopic in the embedding direction. The first fastener T2 is configured to fix the fixed support plate T1 to the frame structure L at any telescopic position.

[0073] Specifically, taking the inner side of the corner M as an example, where a support structure T is provided, such as... Figure 8 As shown, the fixing plate T1 is embedded inside the corner portion M and can extend and retract along the embedding direction. By extending and retracting in the embedding direction, the contact area between the fixing plate T1 and the display module can be adjusted. Thus, the embedding depth of the fixing plate T1 in the embedding direction can be adjusted according to the size of the display module's frame area (non-display area). This ensures that the fixing plate T1 can support the display module while preventing it from affecting the drop ball test of the display module due to contact with the display area; that is, it avoids affecting the test results due to the fixing plate T1's support of the display area.

[0074] The first fastener T2 can be a screw. When the embedding depth of the fixing plate T1 is adjusted according to the size of the display module frame area, the fixing plate T1 can be fixed with a screw to prevent the fixing plate T1, whose embedding depth has been determined, from continuing to move in the embedding direction.

[0075] It should be noted that the specific number of the pallet structure T and the number of the fixed pallet T1 and the first fixing member T2 in the pallet structure T can be set according to actual needs, and no limit is imposed here.

[0076] In some embodiments of this application, such as Figure 4 and Figure 8As shown, at least one blocking structure D extending toward the center of the frame structure L can also be provided on the frame structure L; the blocking structure D and the support plate structure T cooperate to form a fixed space along the thickness direction of the frame structure L.

[0077] Specifically, a blocking structure D may be provided on the first corner structure M1, the second corner structure M2, the first extension structure N1, and / or the second extension structure N2.

[0078] In application, the display module to be tested can be placed in a fixed space. By adjusting the size of the fixed space, the blocking structure D and the support structure T can clamp the display module to be tested, so as to prevent the display module from moving or even moving out of the fixed space due to external impact during the test.

[0079] To avoid affecting test results due to movement of the display module while it is fixed by the fixed components, such as Figure 4 and Figure 8 As shown, the blocking structure D may include a stop block D1 disposed on one side of the frame structure L and a second fastener D2 that fixes the stop block D1 to the frame structure L.

[0080] The size of the fixing space can be adjusted by adjusting the position of the second fixing member D2 in the thickness direction of the frame structure L; and / or the extension length of the stop block D1 toward the center of the frame structure L is adjustable, and the second fixing member D2 is also configured to fix the stop block D1 to the frame structure at any telescopic position of the stop block D1.

[0081] Different display modules may have different thicknesses. By adjusting the position of the second fixing member D2 in the thickness direction of the frame structure L, the size of the fixing space can be adjusted, which can further improve the versatility of the fixing components and ensure that the frame structure L can be used for display modules of various thicknesses.

[0082] Furthermore, the extension length of the stop D1 toward the center of the frame structure L is adjustable, which can improve the versatility of the fixing components and make it suitable for display modules of more sizes.

[0083] Specifically, taking the blocking structure D as an example, which is respectively set on the corner part M and the extension part N, in order to make it easier to adjust the position of the blocking block D1, such as Figure 4 and Figure 8 As shown, the stop block D1 and the frame structure L are slidably connected via a third sliding rail g3. Specifically, the third sliding rail g3 is set on the frame structure L, and the extension length of the stop block D1 towards the center of the frame structure L via the third sliding rail g3 is adjustable. By adjusting the sliding dimension of the stop block D1 on the third sliding rail g3, the blocking dimension of the blocking structure D can be adjusted. The blocking dimension is the length by which the stop block D1 extends into the hollow area of ​​the frame structure L due to sliding.

[0084] It is important to understand that the sliding dimension of the stop D1 can be adjusted according to the size of the display module's bezel area. Specifically, the stop D1 can be adjusted so that it slides into the bezel area of ​​the display module. This ensures that the stop D1 can block the display module while preventing it from contacting the display area of ​​the display module and thus affecting the ball drop test. In other words, it avoids the test results being affected by the stop D1's obstruction of the display area.

[0085] After adjusting the fixed position of the stop block D1 according to the size of the display module bezel area, the second fixing component D2 can be used to fix the stop block D1 in that position to ensure the stability of the obstruction of the display module. In application, the second fixing component D2 can be a screw. The screw is set on the stop block D1, and after the position of the stop block D1 is adjusted, the screw can be used to fix the stop block D1 to the frame structure L, thereby obstructing the display module and thus cooperating with the support structure T to fix the display module.

[0086] In application, the second fixing member D2 can be made of a longer screw so that the height of the screw on the stop D1 can be adjusted to accommodate display modules of different thicknesses.

[0087] It should be noted that, to better protect the display module, a buffer layer can be placed at the bottom of the screw to prevent damage to the display module when fixing the stop block D1 with the screw. The material of the buffer layer can be selected according to actual needs and is not limited here.

[0088] Furthermore, the specific number of the blocking structure D and the stop block D1 and the second fixing member D2 in the blocking structure D can be set according to actual needs, and is not limited here.

[0089] In some embodiments of this application, the fixing component may further include a buffer strip disposed on the inner side of the frame structure L.

[0090] Specifically, the buffer strip can be attached to the inside of the frame structure L so that the buffer strip is located between the display module to be tested and the frame structure L, and is used to protect the edge of the display module.

[0091] In application, the buffer strip can be attached to the area inside the frame structure L that contacts the display module to be tested. The material of the buffer strip can be set according to actual needs, such as rubber, foam, etc.

[0092] In some embodiments of this application, the fixing component may further include a vacuum adsorption device; the vacuum adsorption device can be used to fix the frame structure.

[0093] In application, after forming a frame structure by using multiple corners and extensions, the adsorption characteristics of the vacuum adsorption device can be used to adsorb each corner and extension of the frame structure, fixing it on the adsorption device, thereby improving the stability of the frame structure and avoiding failure of the enclosed splicing of multiple corners and extensions during the test.

[0094] As an optional implementation of the disclosure of this application, embodiments of this application also provide a display module test fixture, which may include the fixing components as described in any of the above embodiments.

[0095] Preferably, the display module test fixture may also include a ball-dropping device.

[0097] The above description of the disclosed embodiments enables those skilled in the art to make or use this application.
