Referring to fig. 1, the present embodiment provides a flexible screen testing apparatus 100 for detecting a bending performance of a flexible screen 300. The flexible screen testing device 100 comprises a foldable base plate 10, a positioning assembly 30 and a clamping assembly 50, wherein the foldable base plate 10 is used for bearing a flexible screen 300, the positioning assembly 30 is arranged opposite to the foldable base plate 10, the clamping assembly 50 is connected between the foldable base plate 10 and the positioning assembly 30, and the clamping assembly 50 is at least partially arranged on one side of the positioning assembly 30, which faces away from the foldable base plate 10, so as to apply pressure towards the foldable base plate 10 to the positioning assembly 30, so that the positioning assembly 30 can press the flexible screen 300 on the foldable base plate 10.
In the present application, the flexible screen 300 to be tested is a display panel with bending capability, such as an organic light-Emitting Diode (OLED) display panel, an active matrix organic light-Emitting Diode (AMOLED) display panel, and the like. The flexible screen 300 has a flexible portion so that it can be folded or unfolded with respect to the flexible portion. Further, the flexible screen 300 includes a first flat section 3001, a second flat section 3003, and a flexible display section 3005. The flexible display portion 3005 is connected between the first flat portion 3001 and the second flat portion 3003, and the first flat portion 3001 and the second flat portion 3003 can be folded or unfolded with respect to each other by the flexible display portion 3005.
In the embodiment of the present application, the foldable substrate 10 has two opposite foldable sides, and the two sides can be turned over or/and folded under an external force until the two sides are folded or unfolded. Therefore, when the flexible screen 300 is stacked on the foldable substrate 10, the flexible screen 300 can be driven to be synchronously bent by means of the bending characteristics of the foldable substrate 10, so as to test the bending performance of the flexible screen 300.
Further, in the present embodiment, the foldable substrate 10 includes a first substrate 12 and a second substrate 14, and the first substrate 12 and the second substrate 14 are disposed at a distance from each other and can be turned over with respect to each other. The first substrate 12 is substantially plate-shaped and is used for carrying the first flat portion 3001 of the flexible screen 300, and the second substrate 14 is substantially plate-shaped and is used for carrying the second flat portion 3003 of the flexible screen 300. It should be understood that the terms "first" and "second" in this specification are used for descriptive purposes only and are not to be construed as indicating or implying relative importance or implying any number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one such feature.
In some embodiments, when the first substrate 12 and the second substrate 14 are in the flat state, the side edges of the two substrates are disposed at intervals, and a space corresponding to the flexible display portion 3005 of the flexible screen 300 is formed between the first substrate 12 and the second substrate 14, so as to prevent the bending movement of the flexible display portion 3005 from being interfered, thereby ensuring the smoothness of the testing process of the flexible screen 300 and preventing the flexible screen 300 from being damaged.
In the embodiment shown in fig. 1, the foldable substrate 10 further includes a flexible portion 16, the flexible portion 16 is connected between the first substrate 12 and the second substrate 14, and the flexible portion 16 is used for supporting the flexible display portion 3005 of the flexible screen 300 to prevent the flexible display portion 3005 from collapsing, thereby improving the reliability of the bending test. In the present embodiment, the flexible portion 16 has a bendable characteristic, so that the first substrate 12 and the second substrate 14 can be folded relatively by the flexible portion 16. Further, the foldable substrate 10 may be an integrally formed structure, and the elastic modulus of the flexible portion 16 is smaller than the elastic modulus of other portions of the foldable substrate 10, such as the elastic modulus of the first substrate 12 or the second substrate 14, so as to ensure that the flexible portion 16 has high bending performance.
It should be noted that the above-mentioned "elastic modulus" can be understood as a general physical concept, which is a measure of the magnitude of the object's ability to resist elastic deformation. In general, the bonding mode, crystal structure, chemical composition, microstructure, temperature, etc. of an object or material may affect the magnitude of the elastic modulus. For objects made of metal, their elastic modulus differs depending on alloy composition, heat treatment state, cold plastic deformation, and the like. For objects made of ordinary non-metals and metals, the cross-sectional shape and area used to carry the load will affect the magnitude of the modulus of elasticity. In the present embodiment, various schemes are provided to control the elastic modulus of the flexible portion 16 to be smaller than that of other portions of the foldable substrate 10, for example, different materials or different processing techniques are selected to prepare the flexible portion 16 and other portions of the foldable substrate 10, etc., but the embodiments illustrated in the present specification should not be limited thereto. For example, as shown in fig. 1, the foldable substrate 10 may be an integrally formed connection structure, and the flexible portion 16 has a plurality of concave structures or a plurality of hollow structures (not shown), so that the flexible portion 16 is more easily elastically deformed than other portions; as another example, the flexible portion 16 may have a thickness that is less than the thickness of other portions of the foldable substrate 10, and so on. It should be noted that, in the description of the present application, "a plurality" means at least two, e.g., two, three, etc., unless explicitly specifically defined otherwise.

Under the control of the spindle controller 18, the spindle mechanism 17 drives the first substrate 12 and the second substrate 14 to flip relatively. The rotation axis controller 18 may be a rotation motor or a steering engine having an input panel, which relatively turns the first substrate 12 and the second substrate 14 to a predetermined angle according to a user operation received by the input panel, so that the flexible screen testing apparatus 100 can independently complete the test of the flexible screen 300 without relying on other turning machines, thereby reducing the testing cost. Further, the spindle controller 18 may have an angle sensor (e.g., a hall sensor, etc.) to precisely control the angle between the first substrate 12 and the second substrate 14.

Further, in this embodiment, the first friction part 193 is substantially in the shape of a solid shaft, the second friction part 197 is substantially in the shape of a hollow tube, the first friction part 193 is accommodated in the second friction part 197, and the outer surface of the first friction part 193 is in interference fit contact with the inner surface of the second friction part 197, the interference fit between the first friction part and the second friction part 197 enables the second friction part 197 and the first friction part 193 to rotate under the action of a certain torque, and after the torque is cancelled, the first connecting part 191 and the second connecting part 195 form a self-lock under the action of the friction force of the two friction parts, so that the two connecting parts can be maintained at any position. Further, the outer surface of the first friction part 193 is substantially tapered, and has a taper angle in the range of 0.5 ° to 10 °. Correspondingly, the inner wall of the second friction part 197 may also be a tapered surface, and the taper of the tapered surface is equal to the taper of the outer surface of the first friction part 193, so as to facilitate the insertion fit between the two parts and improve the friction force between the two parts. Furthermore, the second friction part 197 is provided with a through hole, and one end of the second friction part 197, which is far away from the first friction part 193, has elasticity and can be elastically deformed to change the aperture of the through hole.
