Fig. 1 is a schematic structural diagram of a curled display module according to an embodiment of the present invention. As shown in fig. 1, the apparatus includes: a flexible display panel 101, an inflatable support assembly 102, and a crimping assembly 103.
The flexible display panel 101 is fixed with the curling assembly 103 so that the curling assembly 103 spreads or curls the flexible display panel 101. The inflatable support assembly 102 is secured to the flexible display panel 101 and the crimping assembly 103 such that the inflatable support assembly 102 is retracted as the flexible display panel 101 is deployed or crimped.
Wherein the flexible display panel 101 may include an unfolded state and a curled state; the flexible display panel 101 in the unfolded state, a user can interact with the flexible display panel 101 through a touch operation. The flexible display panel 101 in the curled state occupies less space and is convenient to carry and store.
When the flexible display panel 101 is in the unfolded state, the inflatable support assembly 102 is in the inflated state and can support the back (non-display surface) of the flexible display panel 101, so that the strength of the flexible display panel 101 can be enhanced, and the touch experience is improved; when the flexible display panel 101 is in a curled state, the inflatable support component 102 is in a deflated state, and the inflatable support component 102 in the deflated state occupies less space and is convenient to carry and store;

The flexible display panel 101 in the curled state and the inflatable support member 102 in the deflated state may be housed in different spaces, or may be housed in the same space, and may be specifically set according to actual needs.
In some embodiments, as shown in fig. 2, the inflatable support assembly 102 may include a cushioning inflatable membrane 21 and a membrane spool 22.
The film spool 22 is mounted on the crimping assembly 103. As shown in fig. 2, the film winding shaft 22 and the curling assembly 103 may have a sleeve structure, and the film winding shaft 22 may be installed in the curling assembly 103. As shown in fig. 3, the diameter of the film winding shaft 22 may be smaller than the diameter of the curling assembly 103, and when the film winding shaft 22 and the curling assembly 103 are wound and unwound, the curling linear speeds of the film winding shaft and the curling assembly 103 may be set to be consistent or inconsistent, and may be specifically determined according to actual needs. For example, the buffer inflatable film 21 may be an elastic member, the length of which increases after inflation and the length of which decreases after deflation, and the linear speed of the film winding shaft 22 when the buffer inflatable film 21 is curled may be smaller than the linear speed of the curling member 103 when the flexible display panel 101 is curled, and the linear speed of the film winding shaft 22 when the buffer inflatable film 21 is unwound may be smaller than the linear speed of the curling member 103 when the flexible display panel 101 is unwound, in order to realize the supporting and storing functions.

Based on the above-mentioned structure, when this buffering inflatable membrane 21 is in the state of aerifing, can support at flexible display panel 101 back, be located between the third end 231 of flexible display panel 101 of roll up membrane axle 22, the buffering inflatable membrane 21 under the state of aerifing can provide outside tension, tighten flexible display panel 101 to the hardness of the buffering inflatable membrane 21 under the state of aerifing strengthens, is difficult to take place deformation, and this buffering inflatable membrane 21 supports on flexible display panel 101 for flexible display panel 101 also is difficult to take place deformation, with this rigidity that can strengthen flexible display panel 101 has promoted the touch-control experience.
In some embodiments, the crimp assembly 103 may be a multi-segment structure that forms a gap therebetween that may be used to cushion the passage of the inflatable membrane 21. The number of cushioning gas-filled membranes 21 may be plural, and the number of cushioning gas-filled membranes 21 may correspond to the number of gaps in the crimping assembly 103, one cushioning gas-filled membrane 21 for each gap.
The cushioning inflatable membrane 21 may include one or more strips. When the curling component 103 can be of a multi-section structure, the gaps of the curling component 103 can be uniformly distributed when the buffering inflatable films 21 are multiple, and the buffering inflatable films 21 can be uniformly distributed on the flexible display panel, so that the rigidity of the whole plane of the flexible display panel 101 can be enhanced, the deformation difficulty of the flexible display panel 101 is higher, and the touch experience is better.

The power supply is used for supplying power to the controller, the first motor and the second motor. The controller is used for controlling the air pump and the air release valve through the first motor, and the controller is used for controlling the film winding shaft and the screen winding shaft through the second motor. The controller may be a programmable logic controller (Programmable Logic Controller, PLC).
In some embodiments, as shown in fig. 3, the curling assembly 103 further includes a platen shaft 23, the platen shaft 23 and the film reeling shaft 22 may be connected by a gear, and the second motor may control the platen shaft 23 and the film reeling shaft 22 to simultaneously rotate at the same linear speed.
In some embodiments, the screen winding shaft 23 may include a plurality of segments of pipe shafts, and the inner diameter of the pipe shaft is larger than the outer diameter of the film winding shaft 22, each segment of pipe shaft of the screen winding shaft 23 is sequentially sleeved on the film winding shaft 22, and a gap between every two adjacent pipe shafts is used for buffering the gas filled film 21.

As an example, the crimping assembly may include an outer housing within which an inflator, a deflate valve, a controller, a film spool, a screen spool, etc. may be mounted, and which may also be used to place the flexible display panel in a crimped state and the inflatable support assembly in a deflated state.
In some embodiments, the side wall of the film winding shaft may be provided with an automatic air charging hole, and the film winding shaft and the curling assembly may be controlled by a second motor. The two ends of the automatic air charging hole are fixedly used for buffering an air charging film, one end of the automatic air charging hole is used for charging, and the other end of the automatic air charging hole is used for discharging. When the flexible display panel is in a stowed state (which may also be referred to as a rolled state), the cushioning inflatable membrane is rolled outside the membrane roll.
The second motor can control the rotation operation of the film winding shaft and the curling assembly simultaneously.
When the flexible display panel is required to be scratched (the scratching is the initial action of the unfolding process), the motor can control the curling component to rotate anticlockwise, after the flexible display panel is scratched, the controller can control the output of the motor, so that the inflator pump hidden in the curling component inflates the buffering inflation film, and the film is fully filled with gas for supporting the screen body;
