Abstract

A display apparatus comprises a display device including a display panel and a back cover on a rear surface of the display panel, and a curvature variation device at the back cover to vary a curvature of the display device, the curvature variation device may include an arc member at a rear region of the display device parallel to a first direction, a supporting plate at the rear region of the display device, a rotation driver on the supporting plate, a rectilinear driver on the supporting plate to perform a rectilinear motion, a rotation link part coupled to a center portion of the arc member on the supporting plate to rotate the center portion of the arc member based on a rectilinear motion of the rectilinear driver, and a holder part rotatably supporting the center portion of the arc member on the supporting plate.

Dependent claims

A display apparatus comprising:

a display device including a display panel configured to display an image and a back cover disposed at a rear surface of the display panel;
and
a curvature variation device disposed at the back cover and varying a curvature of the display device,
wherein the curvature variation device comprises:
an arc member disposed at a rear region of the display device parallel to a first direction;
a supporting plate disposed at the rear region of the display device;
a rotation driver disposed at the supporting plate;
a rectilinear driver disposed on the supporting plate to perform a rectilinear motion in a second direction intersecting along the first direction based on a rotation of the rotation driver;
a rotation link part coupled to a center portion of the arc member on the supporting plate to perform a rotational motion based on a rectilinear motion of the rectilinear driver to rotate the center portion of the arc member;
and
a holder part rotatably supporting the center portion of the arc member on the supporting plate.
