AI Technical Summary
Technical Problem
The existing foldable display devices are easily damaged due to excessive pressure during bending, resulting in a shortened service life.
Method used
The shaft protection piece made of shape memory alloy is used to adapt to the changes in the bending state by presenting different body phase states (austeinite phase and martensite phase) under different bending states, thereby providing better support and protection effects.
Benefits of technology
The service life of the foldable display device is extended, the damage to the parts during bending is avoided, and the support of the shaft protection is improved.
