Problems solved by technology

However, since the mobile device disclosed in this patent publication cannot maintain the curved region of the folded display in a flat state due to the empty spaces between the links of the hinge, the curved region of the unfolded display is pushed by an external force, and for this reason , the image is distorted
Also, since the curved area of ​​the display that is bent at a specific curvature with respect to the hinge is exposed, the curved area of ​​the display can be damaged by an external impact

Abstract

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.

Description

[0001] Cross References to Related Applications [0002] This application claims priority from Korean Patent Application No. 10-2014-0195899 filed on December 31, 2014, which is hereby incorporated by reference as if set forth in its entirety herein. technical field [0003] The present invention relates to a foldable display device, in particular to a foldable display device that is bent with a specific curvature or folded into a flat state. Background technique [0004] Display devices using a flat display panel such as a liquid crystal display (LED) device, a plasma display device, an organic light emitting display device, an electrophoretic display device, or an electrowetting display device are generally applied to notebook computers, portable electronic devices, televisions (TVs) ) and the monitor. [0005] Recently, even in portable electronic devices, demand for large screens is increasing; therefore, devices including display units displaying large screens by conne...
