In some embodiments, the test box 100 is a rectangular box, and includes a front wall 101 and a rear wall 102 arranged at intervals in a first direction, a first side wall 103 and a second side wall 104 arranged at intervals in a second direction, and a top wall 105 and a bottom wall 106 arranged at intervals in a third direction. The closable test area is defined by the front wall 101, the rear wall 102, the first side wall 103, the second side wall 104, the top wall 105 and the bottom wall 106. In some examples, the front wall 101 is configured as an openable and closable door structure, and the test area is opened or closed by opening and closing the front wall 101, that is, whether the test area is closed or not is controlled.

[0040] Reference Figure 2 The test system further comprises a slot member 200, which is configured as a support carrier for the object to be tested (i.e., the screen), and is configured to be switchable between a test position and an observation position. Exemplarily, the slot member 200 is a circular frame, and comprises two first frames 201 spaced apart in the second direction and two second frames 202 spaced apart in the first direction. In some embodiments, the first frames 201 and the second frames 202 are provided with scales (not shown) to facilitate the staff to read the scale parameters of the screen. When the slot member 200 is in the test position, the slot member 200 is placed horizontally to facilitate the subsequent contact and pressure gauge 501 action to realize the screen film thickness and tension test. When the slot member 200 is in the observation position (i.e., the operator moves along the Figure 2 When testing in the observation direction, the slot member 200 is arranged at a certain angle (for example, 85°) to the horizontal plane to cooperate with the subsequent lamp member 204 to facilitate the staff to observe the appearance of the screen. In some embodiments, the slot member 200 has a first end and a second end in the first direction, wherein the first end of the slot member 200 is arranged adjacent to the front wall 101 of the box member, and the slot member 200 is configured to rotate around the first end, and the slot member 200 is switched between the test position and the observation position by rotating the slot member 200 around the first end. Exemplarily, the first end of the slot member 200 is rotatably mounted on the first side wall 103 and / or the second side wall 104 through a rotating shaft. At this time, the axis of the rotating shaft of the slot member 200 extends along the second direction. Continue to refer to Figure 2The switching of the above-mentioned slot member 200 between the test position and the observation position is realized by a driving structure. In some embodiments, the above-mentioned driving structure includes at least one cylinder 203 arranged adjacent to the first end of the slot member 200 and extending along the third direction.
