[0032] In order to make the objectives, technical solutions, and advantages of the embodiments of the present disclosure clearer, the technical solutions of the embodiments of the present disclosure will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present disclosure. Obviously, the described embodiments are some, but not all, of the embodiments of the present disclosure. All other embodiments obtained by those of ordinary skill in the art based on the described embodiments of the present disclosure without creative efforts shall fall within the scope of protection of the present disclosure.

[0033] Unless otherwise defined, the technical terms or scientific terms used in the present disclosure shall have the ordinary meanings understood by those of ordinary skill in the art to which the present disclosure pertains. The "first", "second", and similar terms used in the present disclosure do not denote any order, quantity, or importance, but are only used to distinguish different components. The terms such as "including" or "comprising" mean that the elements or objects appearing before this word cover the elements or objects listed after this word and their equivalents, without excluding other elements or objects. The terms such as "connected" or "coupled" are not limited to physical or mechanical connections, but may include electrical connections, whether direct or indirect. The terms such as "upper", "lower", "left", "right", etc. are only used to represent relative positional relationships, and when the absolute position of the object being described changes, the relative positional relationship may also change accordingly.

[0034] In order to keep the following description of the embodiments of the present disclosure clear and concise, the detailed descriptions of known functions and known components are omitted in the present disclosure.

[0035] Existing friction resistance detection equipment can only perform friction resistance tests on flat cover plates, and its structural schematic diagram is as Figure 1As shown, when conducting a friction resistance test on the bridge-shaped bracelet cover plate (i.e., a curved glass cover plate), only the co-deposited sheet can be detected, and it is impossible to truly conduct a friction resistance test on the bridge-shaped bracelet cover plate, resulting in relatively low accuracy of the test results. Therefore, being able to directly conduct the AF friction resistance test on the bridge-shaped bracelet cover plate can effectively control the coating effect of the bridge-shaped bracelet cover plate.

[0036] Based on the above considerations, the first embodiment of the present disclosure provides a friction resistance test device, the structural schematic diagram of which is as Figure 2 shown, including:

[0037] A friction track control device 1, a transmission structure 2, a connecting rod 3, and a friction test structure 4; the friction test structure is arranged at one end of the connecting rod, and the friction test structure is used to conduct a friction test on the curved glass cover plate; one end of the transmission structure is arranged on the friction track control device, and the other end is provided with a connecting rod. The transmission structure moves along a predetermined track on the profiling surface of the curved glass cover plate following the movement of the friction track control device, so as to drive the connecting rod to move on the glass cover plate.

[0038] The above-mentioned profiling surface is a surface curvature imitation surface that is exactly the same as the surface form of the curved glass cover plate and has the same surface curvature as the curved glass cover plate. Thus, when the transmission structure moves, the connecting rod and the transmission structure are equivalent to moving on a surface with the same curvature, ensuring the accuracy of the test results.

[0039] Figure 2 The shown transmission mechanism is a rolling rod that can achieve rolling, which is a relatively simple form of transmission structure. Those skilled in the art can set more complex and precise transmission structures according to actual needs. For example, the transmission structure can include a bracket and small wheels, and the small wheels move on the profiling surface, and the connecting rod is connected through the bracket. Thus, when the small wheels move, it drives the connecting rod to form a synchronous movement on the glass cover plate. Of course, the transmission structure can also be a more refined structure such as one with gears, etc. Those skilled in the art can make corresponding designs according to actual needs, which will not be elaborated here. As long as the transmission structure can achieve its movement on the profiling surface and then drive the movement of the connecting rod.

[0040] In the embodiment of the present disclosure, a transmission structure is provided between the connecting rod and the friction track control device. When the friction track control device moves, the transmission structure can move on a profiling surface that is exactly the same as the curved glass cover plate along with the track of the friction track control device. This movement will drive the friction test structure provided on the connecting rod to move on the curved glass cover plate. Then, along with the reciprocating movement of the friction track control device, the friction test structure also performs the same reciprocating movement on the curved glass cover plate, realizing the friction resistance test of the curved glass cover plate. The device has a simple structure and is easy to improve, solving the problem that the prior art cannot perform the friction resistance test on the curved glass cover plate. The detected friction resistance test structures are all obtained for the curved glass cover plate, and the test results are accurate, ensuring the coating effect.

[0041] The above-mentioned connecting rod 3 and the transmission structure 2 are connected through a first connecting member 5. The first connecting member 5 includes a fixed connection end 16 and a receiving cavity 17 connected to the fixed connection end. The fixed connection end is fixedly connected to the connecting rod, and the transmission structure is received in the cavity of the receiving cavity. There is a first predetermined gap 12 between the outer wall of the transmission structure and the inner wall of the receiving cavity to allow the transmission structure to roll in the receiving cavity. The value range of the above-mentioned first predetermined gap is preferably 0.2 mm to 0.5 mm. The connection cross-section schematic of the connecting rod and the transmission structure can be as Figure 3 shown.

[0042] The above-mentioned friction track control device is provided with a connection hole, and a limiting structure 14 is arranged in the connection hole. The limiting structure is connected to the transmission structure, and the shape of the connection surface where the limiting structure is connected to the transmission structure matches the shape of the connection surface of the transmission structure. The transmission structure is arranged in the connection hole through the limiting structure.

[0043] When the transmission structure is the Figure 2 rolling rod shown, the rolling rod needs to roll, so the limiting structure is only connected to a part of the transmission structure. There is a second predetermined gap 13 between the outer wall of the transmission structure not connected to the limiting structure and the inner wall of the connection hole. The value range of the above-mentioned second predetermined gap is preferably 0.2 mm to 0.5 mm. The connection cross-section schematic of the friction track control device and the limiting structure can be as Figure 4 shown.

[0044] In the above combination Figure 2 in the case where the transmission structure is a rolling rod, the connection parts of the transmission structure with the friction track control device and the connecting rod are described. Of course, if the transmission structure is replaced by a bracket and small wheels, there will be no change in its connection part relative to the connecting rod. However, since small wheels are provided at the bottom of the bracket and the small wheels can roll independently without the bracket rolling together, the connection with the friction track control device can be set as a fixed connection. Those skilled in the art can make adaptive modifications to its similar structure according to actual needs, and they are all within the protection scope of the embodiments of the present disclosure.

[0045] The above-mentioned friction test structure 4 specifically includes a weight 6, a second connecting member 7, and a friction head 8. Among them, the friction head is arranged on the connecting rod through the second connecting member, and the weight is used to weight the friction head. In specific implementation, the above-mentioned friction head is usually made of rubber. The shape of the side of the friction head close to the curved glass cover plate is set to match the curvature of the curved glass cover plate, so as to accurately perform the friction resistance test.

[0046] For the above-mentioned curved glass cover plate, it can be an arc-shaped glass cover plate, such as a U-shaped glass cover plate, a C-shaped glass cover plate, etc. The curved glass cover plate is a component of the display panel. Usually, the display panel can include a curved glass cover plate, a display pixel layer, and a driving circuit layer. The display pixel layer includes a pixel definition layer, a light-emitting unit, etc. For the light-emitting unit, it can include structures such as an anode, a light-emitting material, and a cathode. The driving circuit layer is used to arrange the display pixel layer, and the driving circuit layer can include wirings such as a gate, a source, a drain, a data signal line, and a power supply voltage line. The specific display panel structure can be set according to actual needs and will not be elaborated here.

[0047] The second embodiment of the present disclosure also provides a friction resistance test system, including:

[0048] A profiling carrier device and the friction resistance test device in the first embodiment of the present disclosure; among them, the profiling carrier device can refer to Figure 2 , and generally includes: a first structure 9 provided with a profiling surface, a second structure 11 provided with a carrier for the curved glass cover plate 10, and the step height 18 between the top surface of the first structure and the top surface of the second structure is set to the thickness of the curved glass cover plate.

[0049] For the thickness range of the curved glass cover plate, it is preferably 0.4 mm - 2.0 mm; it is a conventional means in the art to design different profiling carrier devices for curved glass cover plates with the same curvature but different thicknesses. However, curved glass cover plates with the same curvature but different thicknesses have the common feature of the same curvature. In order to reduce the manufacturing cost, the embodiments of the present invention provide a solution that can share the profiling carrier device for curved glass cover plates with the same curvature but different thicknesses. The above-mentioned profiling carrier device can also include a height adjusting member 19, which is arranged above the second structure and is used to adjust the step height to make the curved glass cover plate and the profiling surface at the same height. Furthermore, curved glass cover plates of the same size but different thicknesses can share a profiling carrier device, reducing the manufacturing cost.

[0050] As Figure 5 shown, the curved glass cover plate relative to Figure 2The thickness of the shown curved glass cover plate is reduced. In order to share the profiling bearing device, a layer of height adjusting member 19 is added under the curved glass cover plate, so as to adjust the top surface of the curved glass cover plate and the top surface of the profiling surface to be at the same height.

[0051] In a preferred embodiment, the above-mentioned first structure and second structure are an integrally formed structure, and its structural schematic diagram can be as Figure 6 shown. The integrally formed structure can save space and is more portable to move, and can be designed according to different forms of curved glass cover plates.

[0052] The existing friction resistance test scheme for glass cover plates can only perform friction resistance tests on flat glass cover plates. Figure 7 It is a schematic diagram of the water contact angle test after friction.

[0053] After testing with the friction resistance test system provided by the embodiments of the present disclosure, the profiling surface and the form of the curved glass cover plate are completely consistent. The friction trajectory control device drives the transmission structure to roll on the profiling surface, so as to drive the friction head to rub the curved glass cover plate through the connecting rod. The friction weight is determined by the weights, and the arc-shaped profiling surfaces of the friction head and the curved glass cover plate ensure that the force on the glass by the friction head is consistent during the friction process and the wear of the friction head is uniform. Figure 8 It is a schematic diagram of the water contact angle test after friction.

[0054] During the repeated process of the friction resistance test for the curved glass cover plate, the conventional friction resistance specification is 2,500 cycles, and the water contact angle > 100°. The definition of one cycle is starting position → middle position → end position → middle position → starting position. The friction stroke of the friction head (rubber or steel wool) can be defined according to the size of the curved glass cover plate. For the VA window display area of the curved glass cover plate with a length of 35 mm, the stroke can be specified as the arc length of 15 mm - 25 mm.

[0055] In addition, although exemplary embodiments have been described herein, the scope includes any and all embodiments based on the present disclosure having equivalent elements, modifications, omissions, combinations (e.g., schemes that cross various embodiments), adaptations, or alterations. The elements in the claims will be broadly interpreted based on the language used in the claims and are not limited to the examples described in this specification or during the implementation of this application, and the examples will be interpreted as non-exclusive. Therefore, this specification and examples are intended to be considered only as examples, and the true scope and spirit are indicated by the full scope of the following claims and their equivalents.

[0056] The foregoing description is intended to be illustrative and not restrictive. For example, the above examples (or one or more aspects thereof) may be used in combination with each other. For example, other embodiments may be used by those of ordinary skill in the art upon reading the above description. Additionally, in the above detailed description, various features may be grouped together to simplify the disclosure. This should not be construed as an intention that any non-claimed disclosed feature is necessary for any claim. On the contrary, the subject matter of the disclosure may be less than all of the features of a particular disclosed embodiment. Thus, the following claims are hereby incorporated into the detailed description as examples or embodiments, where each claim stands on its own as a separate embodiment, and it is contemplated that these embodiments may be combined with each other in various combinations or permutations.
