BACKGROUND 
       [0001]    1. Technical Field 
         [0002]    The present disclosure generally relates to a test system and method, especially to a system and method for testing the shock-resistance of an object, such as a display panel. 
         [0003]    2. Description of Related Art 
         [0004]    A display device needs to pass a plurality of tests before it is put on the market. An impact test is used to test the impact performance or the shock-resistance of the display device. In testing, a tester positions of a display device on a test desk, and then uses an impact ball to impact the display device. However, in real-life use of the display device, the display device is not always static when the display device impacts with other bodies, thus the factory test result may deviate from the real shock-resistant ability of the display device. 
         [0005]    What is needed, therefore, is a means which can overcome the described limitations.

     DETAILED DESCRIPTION 
       [0013]    Reference will be made to the drawings to describe the embodiments. 
         [0014]      FIG. 1 , illustrates a test system  1  in accordance with an exemplary embodiment. The test system  1  is configured to simulate an impact between a first body  100  and a second body  300 , and obtain a result quantifying the shock-resistance of the first body  100  or the second body  300 . In the embodiment, the first body  100  serves as a body under test, and the second body  300  serves as an impact component. 
         [0015]    The test system  1  includes a rotating device  10  and a stationary device  30 . The rotating device  10  is rotatable around a center axis  11 . One of the first and second bodies  100 ,  300 , such as the first body  100 , is mounted on the rotating device  10 , and moves together with the rotating device  10 . The stationary device  30  is configured to support the non-moving body, such as the second body  300 , and can locate the second body  300  in the path of the moving first body  100 . 
         [0016]    Referring also to  FIG. 2 , the rotating device  10  may include a spindle  110 , a rotating arm  130 , and a holding portion  131 . The spindle  110  and the holding portion  131  are interconnected by the rotating arm  130 . One of the ends of the rotating arm  130  defines a hole (not labeled), the spindle  110  is fixed in the hole, a rotating axis of the spindle  110  coincides with the center axis  11 , and the rotating arm  130  rotates together with the spindle  110 . The rotating arm  130  may be perpendicular to the spindle  110 . The holding portion  131  is detachably mounted to the other end of the rotating arm  130  or integrally formed at the other end of the rotating arm  130 . The first body  100  is held by the holding portion  131 . In this illustrated embodiment, the first body  100  is a display panel. The first body  100  rotates together with the rotating arm  130  in a direction as indicated by the arrow X in  FIG. 1 . 
         [0017]    The stationary device  30  is positioned on the path  13  traced by the first body  100 . The stationary device  30  includes a main body  320  and a telescopic pole  310  mounted on the main body  320 . The second body  300  is fixed to the telescopic pole  310 . The telescopic pole  310  is extendable and can be stretched or shrunk in length. When the telescopic pole  310  is extended, the second body  300  is put on the path  13  traced by the first body  100  at a certain point C. When the telescopic pole  310  is retracted, the second body  300  is removed from the path  13  traced by the first body  100  and not subject to any impact or collision. 
         [0018]    Referring also to  FIG. 3 , the test system  1  further includes a driving unit  150 , a position-detection unit  170 , and a control unit  190 . The driving unit  150  is configured to drive the spindle  130  to rotate. The position-detection unit  170  is configured to detect when the first body  100  arrives at a point S of the path  13  traced by the first body  100  and generate a signal when the first body  100  arrives at point S of the path  13  traced by the first body  100  under the condition that the telescopic pole  310  is in the extended state. 
         [0019]    The point S is located at a predetermined distance before the first body  100  arrives at the point C when the first body  100  is moving along the path  13  traced by the first body  100  in the X direction. The control unit  190  receives and processes the signal, and then outputs a control signal to turn off the driving unit  150 . In this illustrated embodiment, the circumferential distance between the point S and the point C is 5 centimeters. 
         [0020]    In this illustrated embodiment, the position-detection unit  170  includes a sensor  172  and a light source  200 . The light source  200  is fixed outside the path  13  traced by the first body  100 , with the light source  200 , the point S of the path  13  traced by the first body  100 , and a center of the path  13  traced by the first body  100  being in alignment. The light source  200  emits light beams, and the light beams pass through the point S of the path  13  traced by the first body  100  and are received by the sensor  172 . When the first body  100  arrives at the point S, the light beams emitted from the light source  200  are blocked from the sensor  172 . The sensor  172  generates a signal based on the change of the received light beams. In this illustrated embodiment, the driving unit  150  is a motor, and the light source is an infrared light source. 
         [0021]    During testing, a tester can first fix the first body  100  to the rotating device  10 , and fix the second body  300  to the stationary device  30  (see  FIG. 1 ), and test the shock-resistance of the first body  100  when the first body  100  impacts the second body  300 . After that, the tester can fix the first body  100  to the stationary device  30 , fix the second body  300  to the rotating device  10  (see  FIG. 4 ), and further test the shock-resistance of the first body  100  when the first body  100  is impacted by the second body  300 . Then, the tester has two test situations from which the total shock-resistance of the first body  100  can be established. The precision of the testing of the shock-resistance of the first body  100  is thus improved. 
         [0022]    Referring to  FIGS. 5-6 ,  FIGS. 5-6  show a flowchart summarizing a method for testing the shock-resistance of the first body  100  according to an exemplary embodiment of the present disclosure. The testing steps are described below. 
         [0023]    In step S 10 , the first body  100  is mounted on the holding portion  131  of the rotating device  10 , and the second body  300  is fixed to the telescopic pole  310  of the stationary device  30 . 
         [0024]    In step S 11 , the stationary device  30  is adjusted to be located just under the plane of the path  13  traced by the first body  100 . When the telescopic pole  310  is extended, the second body  300  intersects the path  13  traced by the first body  100  at point C, and when the telescopic pole  310  is retracted, the second body  300  drops below the plane of the path  13  traced by the first body  100 . 
         [0025]    In step S 12 , the light source  200  is fixed at the outside of the path  13  traced by the first body  100 , so that the light source  200 , the point S of the path  13  traced by the first body  100 , and the center of the path  13  traced by the first body  100  are in alignment, therefore, the light beams emitted from the light source  200  pass through the point of point S of the path  13  traced by the first body  100  and be received by the sensor  172 . 
         [0026]    In step S 13 , the spindle  110  is driven to rotate by the driving unit  170 , and the first body  100  rotates together with the spindle  110  in a direction as indicated by the arrow X in  FIG. 1 . 
         [0027]    In step S 14 , when the first body  100  is rotating along the path  13 , and in a period from when the first body arrives at the point C for the first time to when the first body arrives at the point C for the second time, the telescopic pole  310  is switched to be in the extended state after the first body  100  arrives at the point C for the first time, and the second body  300  is thereby on the path  13  at the point C. The position-detection unit  170  is switched on when the telescopic pole  310  is switched to be in the extended state. When the position-detection unit  170  detects that the first body  100  is at the point S of the path  13 , the position-detection unit  170  outputs the signal to the control unit  190 , and the control unit  190  turns off the driving unit  150 . Inertia carries the first body  100  to continue to the point C for the second time, and the first body  100  impacts the second body  300 . The shock-resistance of the first body  100  is tested when the first body  100  impacts the second body  300 . 
         [0028]    In step S 15 , the first and second bodies  100 ,  300  are exchanged (see  FIG. 4 ), and the shock-resistance of the first body  100  when the first body is impacted by the second body  300  is tested. 
         [0029]    In step S 16 , the tester can determine the total shock-resistance of the first body  100  according to the two impact tests, and the precision of the testing and therefore of the result of the testing of the first body  100  is thus improved. 
         [0030]    It is believed that the present embodiments and their advantages will be understood from the foregoing description, and it will be apparent that various changes may be made thereto without departing from the spirit and scope of the embodiments or sacrificing all of their material advantages.
