Abstract
The present application provides a flexible display device, including a housing, at least one winding mechanism, a flexible display screen and at least one stretching mechanism. When the flexible display screen is in a first state, the stretching mechanism pulls the winding mechanism to pull the flexible display screen out of the winding mechanism; when the flexible display screen is in a second state, the stretching mechanism pulls the winding mechanism to receive the flexible display screen into the winding mechanism. The flexible display device is smaller in size by winding the flexible display screen in the housing.
Claims18
A flexible display device, comprising:
- a housing having a receiving cavity formed therein, wherein an opening is formed on at least one of two opposite side edges of the receiving cavity;
- at least one winding mechanism disposed in the receiving cavity;
- a flexible display screen disposed outside the housing, wherein one end of the flexible display screen extends into the opening and is connected to the winding mechanism;
- and
- at least one stretching mechanism disposed in the receiving cavity, wherein each of the stretching mechanisms is connected to one of the winding mechanisms;
- wherein when the flexible display screen is in a first state, the stretching mechanism pulls the winding mechanism to move in a direction away from the housing to pull the flexible display screen out of the winding mechanism;
- when the flexible display screen is in a second state, the stretching mechanism pulls the winding mechanism to move in a direction toward the housing to receive the flexible display screen into the winding mechanism;
- wherein the opening is configured as a first opening formed on one side of the receiving cavity;
- and the winding mechanism comprises a first winding member and a first roller having parallel axes and not contacting each other, and the first roller is disposed between the first winding member and the first opening, and the first winding member and the first roller are fixed on the stretching mechanism, and one end of the flexible display screen is connected to the first winding member around the first roller and extends from the first opening out of the housing;
- and
- wherein the winding mechanism further comprises a second roller, and the second roller and the first roller are disposed on two sides of the first winding member, and a distance between the second roller and the first opening is greater than a distance of the first roller from the first opening, and the axis of the first roller and an axis of the second roller are parallel, and the one end of the flexible display screen is connected to the first winding member around the second roller and the first roller in sequence and extends from the first opening out of the housing.
