During application, a fluid, such as water, is introduced into second subchamber 312; the driving device 5 drives the carrier 2 and the pressing cavity 31 to move relatively in the vertical direction, the second sub-cavity 312 of the pressing cavity 31 extends into the placing cavity 412 through the placing opening 411 to apply pressure to the flexible display panel 200, and due to the arbitrary deformation of the fluid, and the cavity wall of the second sub-cavity 312 is the flexible cavity wall 314, so that the second sub-cavity 312 can be in full contact with the flexible display panel 200 (for example, as shown in fig. 3, continuous points P1 and P2 … … Pn on the flexible cavity wall 314 are in contact with the flexible display panel 200), so as to attach the flexible display panel 200 to the curved cover plate 100, thereby preventing a gap from occurring between the flexible display panel 200 and the curved cover plate 100. Since the pressing cavity 31 includes the first sub-cavity 311 surrounded by the rigid cavity wall 313 and the second sub-cavity 312 surrounded by the flexible cavity wall 314, the first sub-cavity 311 has a first opening 3111 facing downward, the second sub-cavity 312 has a second opening 3121 facing upward, and the second opening 3121 is in sealed abutment with the first opening 3111, that is, a part of the pressing cavity 31 is surrounded by the rigid cavity wall 313, and another part is surrounded by the flexible cavity wall 314, but not all is surrounded by the flexible cavity wall 314, so that during the pressing fit of the pressing cavity 31 on the flexible display panel 200, the volume of the part of the second sub-cavity 312 outside the placing cavity 412 is small, so that the volume of the second sub-cavity 312 expanding can be greatly reduced, thereby reducing the deformation of the flexible cavity wall of the second sub-cavity 312 during the pressing fit on the flexible display panel 200, and the deformation of the flexible cavity wall is reduced, which is beneficial to the improvement of the life of the material of the flexible cavity wall 314, the damage is not easy to occur, so that the replacement times of the second sub-cavity 312 can be reduced, and the use cost of the curved surface fitting jig is reduced.

Thus, in the process of pressing the flexible display panel 200 by the pressing cavity 31, the pressure adjusting device 32 can increase the pressure in the second sub-cavity 312 to further increase the pressure of the flexible cavity wall 314 of the second sub-cavity 312 on the flexible display panel 200, so that the flexible display panel 200 and the curved cover plate 100 are more sufficiently attached to each other, and gaps (bubbles) are better avoided between the flexible display panel 200 and the curved cover plate 100.

The moving driving unit 323 drives the adjusting piston 322 to slide along the axial direction of the adjusting sleeve 321 to compress the fluid in the second sub-chamber 312, so as to increase the pressure applied by the flexible chamber wall 314 of the second sub-chamber 312 to the flexible display panel 200.
The pressure adjusting device 32 may have the following structure: the pressure adjusting device 32 comprises an air pump and a ventilation pipeline, one end of the ventilation pipeline is communicated with the air pump, and the other end of the ventilation pipeline is communicated with the second sub-cavity 312. Gas is pumped into the second sub-cavity 312 by the gas pump to increase the pressure in the second sub-cavity 312, so that the pressure applied by the flexible cavity wall 314 of the second sub-cavity 312 to the flexible display panel 200 can be increased. Compare pressure adjustment device 32 and include the embodiment of air pump and vent line, pressure adjustment device 32 includes the embodiment of adjusting cover 321, adjusting piston 322 and removal drive unit 323, only need to remove adjusting piston 322 and just can adjust the pressure in the second subchamber 312, need not frequently to let in gas through the opening in to second subchamber 312, guarantee second subchamber 312, the leakproofness of first subchamber 311 more easily like this, be difficult to cause the fluid leakage, thereby guarantee the stability of the pressure in second subchamber 312 more easily.
