Problems solved by technology

[0006] However, in such rollable display devices, a separate power source such as a motor is required to roll the display panel
In addition, rollable display devices have other disadvantages such as complicated structures and increased part counts
[0007] In addition, foreign matter generated by friction of the operating parts during the rolling operation of the display panel may permeate or move into the space between the operating parts to generate noise, or may move outward to reduce the aesthetic quality of the appearance, which is a problem

Abstract

The invention discloses a rollable display device. The rollable display device includes a roller having a cylindrical shape and an outer circumferential surface on which a display panel is rolled. A cylinder member supports rotation of the roller, using a rotation support member coupled thereto. A housing member is rotatable together with the roller. A torsional elastic member is fixed to the cylinder member and the housing member. A housing inner member is provided on an inner circumferential surface of the housing member, such that impurities are attached thereto. Noise is prevented from being generated by impurities due to friction during operations, and impurities are prevented from moving outwardly.

Description

[0001] Cross application of related applications [0002] This application claims priority from Korean Patent Application No. 10-2017-0110311 filed on Aug. 30, 2017, which is hereby incorporated by reference for all purposes as if fully set forth herein. technical field [0003] One or more embodiments relate to a display device, and more particularly, to a rollable display device in which a display panel can be rolled or unrolled like a scroll. Background technique [0004] In general, research on flat panel display devices such as liquid crystal display (LCD) devices, plasma display devices, field emission display devices, and organic light emitting display devices has been actively conducted. Among these flat panel display devices, LCD devices and organic light emitting display devices have recently become prominent due to their advantages such as suitability for mass production, easy realization of a driving unit, and realization of high resolution. [0005] Recently, r...
