For example, in the field of vehicles, windshields, windows or sunroofs of vehicles may be used as carriers for display media, such transparent display panels having a certain light transmission, while also enabling image display to improve the user experience. The display medium may be in the form of a film, and in the process of manufacturing the display panel, the film may be disposed on the film jig, and then other layer structures (such as a coating film and the like) are formed on the film, so as to manufacture the transparent display panel.

The film jig in this embodiment may also be applied to manufacturing of other display panels, for example: television display panels, computer displays, etc. It can be understood that the film jig in this embodiment can also be applied to verification or debugging of the film. The application scene of the film jig is not limited in this embodiment, and the film jig is only required to be used for fixing the film so as to facilitate processing, debugging or verification.

Illustratively, one 201 of the adjacent two support blocks 201 of the at least two support blocks 201 is provided with an embedded groove 2071 along an end parallel to the other face 202, and the other 201 of the adjacent two support blocks 201 is provided with an embedded block 2081 along an end parallel to the other face 202; the insertion block 2081 is inserted into the insertion groove 2071 when each support block 201 is mounted on the bracket 10 to complete the splice between the adjacent two support blocks 201.

In the above implementation manner, in the two adjacent support blocks 201, the cross-sectional shape of the mounting hole 205 of the outer support block 201 may be a regular shape such as a rectangle or a circle, and of course, the cross-section of the mounting hole 205 of the outer support block 201 may also be another irregular shape, which is not limited in the cross-sectional shape of the mounting hole 205 in this embodiment. Correspondingly, the cross-sectional outline of the inner supporting block 201 parallel to the other surface 202 is the same as the cross-sectional shape of the mounting hole 205 of the outer supporting block 201, and the areas are equal, so that when the outer supporting block 201 is sleeved on the inner supporting block 201, no gap exists between the inner supporting block 201 and the outer supporting block 201, and the other surfaces 202 of the two supporting blocks 201 are spliced into a continuous supporting surface 204 (as shown in fig. 6).

By improving the dimensional accuracy of each support block 201 and the fitting accuracy between adjacent support blocks 201, the gap between the inner support block 201 and the outer support block 201 in the adjacent two support blocks 201 can be further eliminated, and the gap between the other faces 202 of the two adjacent support blocks 201 can be avoided.
