Display device
A display device includes a first rotation member configured to rotate, a second rotation member configured to rotate, the second rotation member being spaced apart from the first rotation member, a conveyance member that is extended between the first rotation member and the second rotation member, is configured to be conveyed between the first rotation member and the second rotation member in accordance with respective rotations of the first rotation member and the second rotation member, and has an inner surface and an outer surface, an abutting movement member that is disposed between the first rotation member and the second rotation member, and is configured to move to cause the conveyance member to be partially pushed up while being abutted against the inner surface, and a display member having flexibility that is attached to the outer surface, and displays an image using an organic light emitting phenomenon.
1. An organic electroluminescence (EL) display device comprising:
a flexible display that is windable or unwindable in a first direction, has first and second ends in the first direction, and includes a plurality of organic light emitting elements;
a movement mechanism that is connected to the first end of the flexible display and is configured to elongate and shorten in the first direction;
a rotation member that is connected to the second end of the flexible display and is configured to wind or unwind the display member therearound in the first direction;
a motor configured to rotate the rotation member such that the flexible display is wound or unwound in the first direction; and
a housing configured to house at least the rotation member and the motor.
2. The display device according to claim 1 , wherein the movement mechanism is configured to elongate or shorten in the first direction in accordance with the motor rotating the rotation member to wind or unwind the flexible display around the rotation member in the first direction.
3. The display device according to claim 1 , wherein the movement mechanism comprises four pivot plates.
4. The display device according to claim 1 , further comprising at least one of:
a roller configured to clean the flexible display;
a brush; or
a blower.
5. The display device according to claim 4 , wherein the roller, the brush, or the blower is configured to clean at least a surface on which the organic light emitting elements are disposed.
6. The display device according to claim 4 , wherein the housing is configured to further house the roller, the brush, or the blower.
7. The display device according to claim 1 , further comprising brushes opposed to each other via the flexible display.
8. The display device according to claim 7 , wherein the brushes are disposed between the support and the rotation member in the first direction.
