The flexible display panel 101 is secured to the curling assembly 103 such that the curling assembly 103 unwinds or curls the flexible display panel 101. The inflatable support assembly 102 is secured to the flexible display panel 101 and the curling assembly 103 so that the inflatable support assembly 102 can be retracted and deployed as the flexible display panel 101 is unfolded or curled.
Wherein the flexible display panel 101 may comprise an unfolded state and a rolled state; the flexible display panel 101 is in an unfolded state, and a user can interact with the flexible display panel 101 through touch operation. The flexible display panel 101 in the rolled state occupies a small space, and is convenient to carry and store.
When the flexible display panel 101 is in the unfolded state, the inflatable supporting assembly 102 is in the inflated state and can support the back surface (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 can be improved; when the flexible display panel 101 is in a curled state, the inflatable support assembly 102 is in a deflated state, and the inflatable support assembly 102 in the deflated state occupies a small space and is convenient to carry and store;

The two ends of the automatic inflation hole are fixedly used for buffering the inflation film, one end of the automatic inflation hole is used for inflation, and the other end of the automatic inflation hole is used for deflation. When the flexible display panel is in a stored state (which may also be referred to as a rolled state), the buffer inflation film is rolled outside the film roll.
The second motor may control the rotational operation of the film spool and the curling assembly simultaneously.
When the flexible display panel is required to be scribed out (the scribing is an initial action of the unfolding process), the motor can control the curling assembly to rotate anticlockwise, and after the flexible display panel is scribed out, the controller can control the output of the motor to enable the inflator pump hidden in the curling assembly to inflate the buffering inflation film, so that the film is filled with gas for supporting the screen body;
