Foldable display apparatus

摘要

Embodiment relate to a structure for supporting a bending portion of a flexible display panel in an unfolded state so that the bending portion does not flex when pressed. The structure also enables the bending portion of the flexible display panel to bend at a predetermined curvature in a folded state. The structure includes two rotating plates rotating about two axes that slide relative to flexible supporting members extending from portions of the flexible display panel that do not bend as the flexible display panel is bent. As the flexible display panel is bent, the distance between ends of the rotating plates are increased so that the bending portion of the flexible display panel would have an increased radius of curvature.

主权项

1. A foldable display device comprising:
a flexible display panel comprising a first display area, a second display area and a bending display area between the first display area and the second display area; a first supporting member under the first display area and extending below a first portion of the bending display area to provide support for the first portion of the bending display area in an unfolded state of the foldable display device; a second supporting member under the second display area and extending below a second portion of the bending display area to provide support for the second portion of the bending display area in the unfolded state, an edge of the second supporting member under the bending display area separated from an edge of the first supporting member under the bending display area by a predetermined distance in the unfolded state, the second supporting member bent away from the second portion of the bending display area in the folded state to increase a distance between the edge of the first supporting member and the edge of the second supporting member; a first rotation plate configured to rotate about a first axis and extend towards the edge of the first supporting member to support a portion of the first supporting member in the unfolded state; and a second rotation plate configured to rotate about a second axis parallel to the first axis, the second rotation plate extending towards the edge of the second supporting member to support a portion of the second supporting member in the unfolded state; and wherein the first supporting member stretches and slides relative to the first rotation plate and the second supporting member stretches and slides relative to the second rotation plate when the first case is rotated relative to the second case.
