Document Type and Number:
WIPO Patent Application WO/2020/255211
Kind Code:
A1
Abstract:
Provided is a lightweight structure that can be used in a flexible screen or a variable-shape display device, etc., is capable, in particular, of stably maintaining a wound storage state and an unwound independent, support state, and can easily move between these two states. The structure is a band- or plate-shaped thin plate, has a convex shape in a cross-section perpendicular to the longitudinal direction, has the side forming the convex shape being the inner circumferential side thereof, and combines and arranges a first member and a second member so as to have the sides thereof that form the convex shape face inwards and so as to be adjacent along the entire longitudinal direction thereof, said first member having a curl in the longitudinal direction thereof so as to wind in a coil and said second member being a band- or plate-shaped thin plate that forms a convex shape in a cross-section perpendicular to the longitudinal direction. As a result, the wound state and a vertically independent state can be stably maintained. The first member and the second member can be easily wound as a result of fixing one end or a section thereof. Furthermore, these members ideally comprise a material having a yield strength of at least 1,000 MPa.
