These are relative concepts and may therefore vary depending on their location and usage. Therefore, these or other directional terms should not be interpreted as restrictive. Furthermore, the terms "first," "second," "third," and similar expressions are used only for descriptive and distinguishing purposes and should not be construed as indicating or implying the relative importance of the corresponding components.

[0036] Please see Figure 1In an embodiment of the present application, a testing device 100 is provided, which comprises a heating device 1, a bearing platform 2 and a detection support 3. The heating device 1 has a heating area formed therein, and one side of the heating device 1 has a first opening 10. The bearing platform 2 is movably installed in the heating area, and at least a part of the bearing platform 2 can be moved out of the heating area through the first opening 10, and the bearing platform 2 is used for bearing at least one display device A to be tested. The detection support 3 is located at one side of the first opening 10, and the detection support 3 comprises a detection structure 33, which is arranged higher than the bearing platform 2, and the detection structure 33 is used for detecting the at least one display device A to be tested on the at least a part of the bearing platform 2 which can be moved out of the heating area.

[0037] In the testing device 100 provided in the embodiment of the present application, since the detection structure 33 is arranged higher than the bearing platform 2, when the at least a part of the bearing platform 2 is moved from the first opening 10 of the heating device 1 towards the detection structure 33, the bearing platform 2 is located below the detection structure 33, and when the at least a part of the bearing platform 2 is moved from the first opening 10 of the heating device 1 towards the heating area, the bearing platform 2 enters the inside of the heating area from below the detection structure 33.

[0038] For example, after the display device A to be tested is installed on the bearing platform 2, the bearing platform 2 is moved to make the detection structure 33 on the detection support 3 align with the display device A to be tested, for example, the bearing platform 2 is partially or entirely moved out of the heating device 1 through the first opening 10, and then the display device A to be tested is lighted for testing. After the initial testing is completed, the bearing platform 2 which is partially or entirely moved out of the heating device 1 is moved again, so that the bearing platform 2 completely enters the heating area of the heating device 1, thereby driving the display device A to be tested on the bearing platform 2 to enter the heating area. After the display device A to be tested enters the heating area, the heating device 1 heats the heating area to a testing temperature, so that the display device A to be tested is exposed to the testing temperature for a certain time. Then, the bearing platform 2 is moved again from the first opening 10 of the heating device 1 to partially or entirely move the bearing platform 2 out of the heating device 1, and the display device A to be tested continues to be exposed below the detection structure 33 of the detection support 3, so that the detection structure 33 re-inspects the display device A to be tested after being heated, thereby realizing secondary testing of the display device A to be tested after being exposed to the heating environment, ensuring the testing quality and testing standard specification of the testing process, and improving the testing efficiency through the integration of the testing device.

[0039] It should be noted that the detection structure 33 comprises an industrial camera. In the embodiment, after the display device A to be tested is lighted, the industrial camera is used for taking a picture, and then through graphic binarization processing, the defective feature parameter values at various positions, such as the brightness, diameter and shape of the points, are calculated, and each defect is classified into a defect list and displayed and archived.

[0040] For example, the display device A to be tested described above can be a mobile phone, a tablet computer, a wearable device, a vehicle-mounted device, an augmented reality (AR) / virtual reality (VR) device, a notebook computer, an ultra-mobile personal computer (UMPC), a netbook, a personal digital assistant (PDA), or the like, which is provided with a display screen.

One end of the flexible circuit board a2 is connected to the mobile phone body a1, and the other end is connected to the bearing platform 2. The flexible circuit board a2 is formed with a BTB female connector and a docking Mark mark. When the flexible circuit board a2 is docked with the bearing platform 2, the docking Mark mark can be used to identify the connector and determine the connection direction position, and then the BTB male connector of the crimping structure is docked based on the BTB female connector.

[0042] Further, the crimping structure is formed on the bearing platform 2, and the BTB male connector of the crimping structure is used to be connected with the BTB female connector on the flexible circuit board a2 of the display device A to be tested.
