     DETAILED DESCRIPTION 
       [0032]    In order to make objects, technical details and advantages of the embodiments of the disclosure apparent, the embodiments of present disclosure will be described in connection with the drawings. Apparently, the described embodiments are just a part but not all of the embodiments of the disclosure. Based on the described embodiments herein, those skilled in the art can obtain other embodiment(s), without any inventive work, which should be within the scope of the disclosure. 
         [0033]      FIG. 1  is a view of an application scenario of a lighting jig  01 , as shown in  FIG. 1 , the lighting jig  01  includes a tray  011  for carrying a display panel A and a support frame  012  for supporting the tray  011 , and the tray  011  is fixedly connected to the support frame  012 . When the display panel A is detected, the lighting jig  01  is placed onto a work table  00  (the work table  00  may be provided in a form of desktop) by means of the support frame  012 , and the display panel A is arranged onto the tray  011  and is lighted up. A staff changes the relative position between himself/herself and the tray  011  by moving his/her own position to vary the viewing angle, and thus to view the display panel A from different perspectives. Due to the need for the staff to move his/her own position, the detection process of the display panel is complicated. In the lighting jig shown in  FIG. 1 , the height of the support frame  012  is fixed, and artificial error may occur in the detection process, for example, due to the height deviation among staffs, there may be differences in the detection results because of the difference between the heights of the staffs. 
         [0034]    To solve the above problem, the embodiments of present disclosure provide a lighting jig, which includes a tray, a support frame and an angle adjusting mechanism, and the tray is in a movable connection with the support frame by means of the angle adjusting mechanism; and the tray is configured to carry the display panel, and the support frame is configured to support the tray. Due to the movable connection of the tray with the support frame by means of the angle adjusting mechanism, it is possible to adjust the angle of the tray by means of the angle adjusting mechanism without the need that the staff moves his/her own position. Therefore, the lighting jig provided by the embodiments of present disclosure solves the problem that the current detection process of the display panel is complicated, and achieves a beneficial effect of simplifying the detection process of the display panel. 
         [0035]    Referring to  FIG. 2 , which illustrates a structural schematic view of a lighting jig  02  provided in one embodiment of the present disclosure, the lighting jig  02  may be used to detect the display panel, such as, to detect the bright spots, the black spots, the foreign matters and the like on the display panel. 
         [0036]    As shown in  FIG. 2 , the lighting jig  02  may include a tray  021 , a support frame  022  and an angle adjusting mechanism  023 . The tray  021  is in a movable connection with the support frame  022  by means of the angle adjusting mechanism  023 , and the angle adjusting mechanism  023  may be used to adjust the angle of the tray  021 ; the tray  021  is configured to carry the display panel B, and the support frame  022  is configured to support the tray  021 . As shown in this figure, in a case that the lighting jig is in an operation state, the tray  021  is disposed obliquely with respect to the horizontal direction, so as to facilitate an operator to view the display panel placed on the tray  021 . 
         [0037]    For example,  FIG. 3  is a structural schematic view of a lighting jig  02  provided in another embodiment of the present disclosure, such a lighting jig  02  may be used to detect a display panel, for example, to detect bright spots, black spots, foreign matters and the like at the display panel. 
         [0038]    As shown in  FIG. 3 , the lighting jig  02  may include a tray  021 , a support frame  022  and an angle adjusting mechanism  023 , the tray  021  is in a movable connection with the support frame  022  by means of the angle adjusting mechanism  023 , the tray  021  is configured to carry the display panel B, and the support frame  022  is configured to support the tray  021 . 
         [0039]    For example, as shown in  FIG. 3 , the angle adjusting mechanism  023  may further include a connecting rod  0231  and a sphere  0232  fixedly connected to one end of the connecting rod  0231 , and the other end of the connecting rod  0231  is connected with the tray  021 , the support frame  022  is provided with a concave C in which the sphere  0232  is arranged, and the sphere  0232  is in contact with an the inner wall of the concave C, hence forming, for example, an universal spherical joint structure, and the tray is rotable around the axis of the support frame by means of the angle adjusting mechanism. 
         [0040]    For example, as shown in  FIG. 3 , the lighting jig  02  further includes a lock mechanism  024  with which the sphere  0232  is in contact. When the lock mechanism  024  is released, the sphere  0232  is movable within the concave C; and when the lock mechanism  024  is locked, the sphere  0232  is fixed within the concave C. For example, the sphere  0232  may be a rigid sphere, and the connecting rod  0231  may be integral with the sphere  0232 , in this way, it is possible to enhance the rigidity of the angle adjusting mechanism  023 . The concave C may be a curved concave (a concave with a curved surface), thus it is possible to facilitate the movement of the sphere  0232  in the concave C. 
         [0041]    For example, the lock mechanism  024  may further include at least two first bolts  0241 , the support frame  022  may comprise a columnar structure, and a lateral side of the support frame  022  is provided with at least two first screw holes (not shown in  FIG. 3 ) communicating with the concave C, each of the at least two first bolts  0241  is able to pass through one of the first screw holes and to press against the sphere  0232  within the concave C, in this way, when a plurality of first bolts  0241  having different extending directions presses against the sphere  0232  at the same time, the sphere can be fixed. In the process of locking the lock mechanism  024  in  FIG. 3 , the movement directions of the at least two first bolts  0241  are distinct. 
         [0042]    For example, the support frame  022  may include a first cylindrical structure  0221  and a second cylindrical structure  0222 , the first cylindrical structure  0221  is provided therein with a cavity (not shown in  FIG. 3 ), the second cylindrical structure  0222  is fixedly arranged in the cavity of the first cylindrical structure  0221 , one bottom surface of the second cylindrical structure  0222  is disposed in the cavity of the first cylindrical structure  0221 , and the other bottom surface of the second cylindrical structure  0222  is provided with the concave C. 
         [0043]    For example, the lighting jig  02  may further include a height adjusting mechanism  025 , the height adjustment mechanism  025  is provided at the support frame  022  for the adjustment of the height of the support frame  022 . In this way, the lighting jig  02  is enabled to eliminate artificial errors (for example, to eliminate errors in the detection results of the staffs having different heights). 
         [0044]    For example, as shown in  FIG. 3 , the height adjusting mechanism  025  includes a second bolt  0251 . A lateral side of the second cylindrical structure  0222  is provided with at least two second screw holes (not shown in  FIG. 3 ) along the height direction of the support frame  022 , and a lateral side of the first cylindrical structure  0221  is provided with at least two third screw holes (not shown in  FIG. 3 ) along the height direction of the second cylindrical structure  0222 , and the second bolt  0251  is able to pass through one of the third screw holes and arbitrary one of the second screw holes sequentially, so as to fixedly connect the first cylindrical structure  0221  and the second cylindrical structure  0222 . For example, each of the second screw holes and each of the third screw holes have their extending directions perpendicular to the height direction of the second cylindrical structure  0222 . 
         [0045]    As an example and also as shown in  FIG. 4  which is a structural schematic view of a first cylindrical structure  0221  provided in the embodiment shown in  FIG. 3 , see  FIG. 4 , the lateral side of the first cylindrical structure  0221  is provided with a third screw hole E. The number of the third screw hole E may be one or more, and the embodiment of present disclosure is not limited thereto. For example, as shown in  FIG. 4 , the number of the third screw holes E may be two. The two third screw holes E are symmetrically disposed at the lateral side of the first cylindrical structure  0221  with the axial sectional plane of the first cylindrical structure  0221  as the symmetrical plane, and the axis x 1  of each third screw hole E may be perpendicular to the height direction y 1 . 
         [0046]    As an example and also referring to  FIG. 5  which illustrates a structural schematic view of a second cylindrical structure  0222  provided in the embodiment shown in  FIG. 3 , see  FIG. 5 , the lateral side of the second cylindrical structure  0222  is provided with at least two second screw holes F along the height direction y 2  of the second cylindrical structure  0222 , and each of the second screw holes F has its axis x 2  perpendicular to the height direction y 2  of the second cylindrical structure  0222 . It should be noted that, in practical situations, according to the difference in the positions and numbers of the third screw hole E at the first cylindrical structure  0221 , the lateral side of the second cylindrical structure  0222  may be provided with a plurality of groups of screw holes P along the height direction y 2  of the second cylindrical structure  0222 , each of the groups of screw holes P includes at least two second screw holes F, the aperture of the second screw hole F may be equal to that of the third screw hole E, and the apertures of the second screw hole F and the third screw hole E are greater than the diameter of the screw rod of the second bolt  0251 , so that the second bolt  0251  can pass through the third screw hole E and arbitrary one of the second screw holes F sequentially, so as to fixedly connect the first cylindrical structure  0221  and the second cylindrical structure  0222 . 
         [0047]    For example, as shown in  FIG. 3 , at least two catching structures (not shown in  FIG. 3 ) is provided at the carrying surface, configured to carry the display panel, of the tray  021 , such a catching structure is configured to catch a display panel. The tray  021  is provided with at least two catching structures, each of which can catch one display panel, and accordingly, the tray  021  may carry at least two display panels at the same time, so that the lighting jig  02  can detect at least two display panels at the same time, thus it is possible to increase the detection efficiency. 
         [0048]    Further, in the lighting jig  02  provided by the embodiment of the present disclosure, the tray  021  is rotatable around the axis of the support frame  022  by means of the angle adjusting mechanism  023 , and as an example, the tray  021  can make a 360-degree rotation about the axis of the support frame  022  by means of the angle adjusting mechanism  023 , so that the staff can detect the display panel from different perspectives without changing his/her own position. For example, to improve the rigidity of the lighting jig  02  so as to ensure the reliability of the rotation of the tray  021  around the axis of the support frame  022 , as shown in  FIG. 3 , the lighting jig  02  further includes a support bar  026 , one end of which is fixedly connected to the tray  021  and the other end of which is fixedly connected to the lateral side of the support frame  022 , and referring to  FIG. 3 , the other end of the support bar  026  is fixedly connected to the lateral side of the second cylindrical structure  0222  of the support frame  022 . 
         [0049]    As an example, referring to  FIG. 6 , which illustrates a front view of a tray  021  provided in the embodiment shown in  FIG. 3 , and referring to  FIG. 6 , the tray  021  includes at least two catching structures  0211  provided on the carrying surface W, configured to carry the display panel, of the tray, such a catching structure is configured to catch the display panel. Each of the catching structures  0211  includes at least two stoppers, and the stoppers include a stationary stopper and a movable stopper. 
         [0050]    For example, as shown in  FIG. 6 , the catching structure includes two stationary stoppers  02111  and one movable stopper  02112 , length directions of the two stationary stoppers  02111  are perpendicular to each other, and the length direction of the movable stopper is perpendicular to the length direction of one of the stationary stoppers  02111 . 
         [0051]      FIG. 6  illustrates by taking the example that two catching structures  0211  are provided on the carrying surface W. The provision of the movable stopper  02112  enables the lighting jig  02  to detect display panels of different sizes, and each of the stationary stoppers  02111  may be fixedly provided on the carrying surface W of the tray  021  by screws (not shown in  FIG. 6 ). As shown in  FIG. 6 , any adjacent two catching structures  0211  may share one stationary stopper  02111 , thus it is possible to reduce the number of the stationary stoppers  02111  which is used to form the catching structure  0211  on the tray  021 . And in the embodiment of the present disclosure, in order to prevent the stoppers (including the stationary stoppers  02111  and the movable stopper  02112 ) from damaging the edge of the display panel, the location, being in contact with the display panel, of the stopper of each catching structure  0211  is provided with a rubber pad  02113 . 
         [0052]    For example, as shown in  FIG. 6 , the carrying surface W of the tray  021  is provided thereon with a slide rail  02114  along which the movable stopper  02112  is movable, so as to adjust the region defined by the stopper for the adaption to display panels of different sizes. The movable stopper  02112  is provided with a fourth screw hole (not shown in  FIG. 6 ), the bottom of the slide rail  02114  is provided with a through hole (not shown in  FIG. 6 ) extending along the thickness direction of the tray  021 , the third bolt can pass through the fourth screw hole of the movable stopper  02112  and the through hole at the bottom of the slide rail  02114  so as to connect the slide rail  02114  with the movable stopper  02112 . 
         [0053]    For example,  FIG. 7  is a front view of a tray  021  carrying a display panel provided in the embodiment shown in  FIG. 3 , referring to  FIG. 7 , the carrying surface W of the tray  021  carries two display panels B, and each display panel B is disposed in a region defined by one catching structure, and each display panel B is provided with a circuit board B 1  which may be a flexible printed circuit, the circuit board B 1  is provided with a connector interface through which the display panel B can be applied with a signal, so that the display panel B is lighted up, and then detection is performed upon the display panel B. 
         [0054]    In summary, the lighting jig provided by the embodiments of the present disclosure includes a tray, a support frame and an angle adjusting mechanism, and the tray is in a movable connection with the support frame by means of the angle adjusting mechanism; and the tray is configured to carry a display panel, and the support frame is configured to support the tray. Due to the movable connection of the tray with the support frame by means of the angle adjusting mechanism, it is possible to adjust the angle of the tray by using the angle adjusting mechanism without requiring the staffs to change their positions. In addition, such a lighting jig can be further provided with a height adjustment mechanism so as to eliminate errors brought by the staffs of different heights in the detection result. Therefore, the lighting jig provided by the embodiments of present disclosure solves the problem that the current detection process of the display panel is complicated, and achieves a beneficial effect of simplifying the detection process of the display panel.
