Display apparatus and electronic device

An electronic device, comprising a display apparatus and a power supply;

• wherein the power supply is configured to power the display apparatus;
• the display apparatus comprises a display panel, a protection housing, an ignition assembly, and a protection assembly;
• wherein the display panel is arranged in the protection housing, and the protection housing comprises a cooperating chamber, the protection assembly comprises a compressible airbag and an ignition material, the cooperating chamber comprises a gas chamber and a storage space, the gas chamber is communicated with the storage space, the storage space is configured to accommodate the ignition material, and the compressible airbag seals an opening of the gas chamber;
• the ignition assembly is connected to the protection housing, the ignition assembly comprises an ignition leading-wire and an ignition leading-ball, one end of the ignition leading-wire is connected to the storage space, and the ignition leading-ball is configured to contact with the other end of the ignition leading-wire when a fall is sensed to ignite the ignition material, so as to increase the air pressure in the gas chamber to inflate the compressible airbag;
• wherein the cooperating chamber comprises an accommodating chamber adjacent to the gas chamber, an opening of the accommodating chamber faces the same direction as the opening of the gas chamber, the protection assembly comprises a protection cover and a rotating rod, the protection cover is located on one side of the compressible airbag away from the gas chamber, the protection cover at least partially covers the opening of the accommodating chamber, the rotating rod is located at the opening of the accommodating chamber, the protection cover is rotationally connected to the protection housing through the rotating rod, and the protection cover is configured to rotate under an action of the compressible airbag after inflation, such that a part of the protection cover is located in the accommodating chamber;
• wherein the compressible airbag comprises a gas leakage hole configured to the deflate gas in the compressible airbag;
• wherein the protection assembly comprises a reset spring connected to the rotating rod, and the reset spring is configured to drive the protection cover to rotate to the side of the compressible airbag away from the gas chamber after the compressible airbag shrinks.
