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.

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.

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.

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.

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 y2 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.

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.
