Flexible display device

A flexible display device comprising:

• a fixed portion;
• a shaft, arranged on the fixed portion;
• a first screen end fixing member, slidably mounted on the fixed portion, and a sliding direction being perpendicular to an axial direction of the shaft;
• a second screen end fixing member, slidably mounted on the fixed portion, and a sliding direction being perpendicular to the axial direction of the shaft;
• a flexible display screen, wound on the shaft, one end of the flexible display screen being fixed to the first screen end fixing member, and the other end of the flexible display screen being fixed to the second screen end fixing member;
• at least one first elastic member, mounted between the fixed portion and the first screen end fixing member, and providing a first elastic force to the first screen end fixing member;
• and
• at least one second elastic member, mounted between the fixed portion and the second screen end fixing member, and providing a second elastic force to the second screen end fixing member;
• wherein the first elastic force at least partially maintains equilibrium with the second elastic force;
• and at least one of a power supply structure or a stress balancing structure arranged between the first screen end fixing member and the fixed portion, the power supply structure and the stress balancing structure are arranged between the first screen end fixing member and the fixed portion, or between the second screen end fixing member and the fixed portion, or between the fixed portion and the shaft, the power supply structure is configured to provide a driving force to the fixed portion to move relative to the first screen end fixing member and an anchoring force when the fixed portion is fixed relative to the first screen end fixing member, and the stress balancing structure is configured to provide the anchoring force when the fixed portion is fixed relative to the first screen end fixing member.
