Problems solved by technology

[0005] However, the existing roll-up flexible display device such as Korean Patent No. 818170 is inconvenient to use because the fixing unit for maintaining the unfolded state of the flexible display is fragile, and it is particularly difficult to perform multi-touch
[0006] For example, Korean Patent Publication No. 2009-0076996, it is difficult to use a hinged frame to support a flexible display in a large-screen display, and the length of the screen that needs to be expanded cannot be adjusted freely.

Abstract

A scroll type flexible display apparatus is provided to improve user convenience while maintaining an unfolded state of a flexible display by a length adjustment member. A flexible display part(102) is rolled and unrolled by being supported by a main body housing(100). A length control member(103) maintains an unrolled state of the flexible display part by being connected to the main body housing. The length control member has a structure which is able to be extended by unrolling the flexible display part. A fixing member fixes the extended length of the length control member.

Description

technical field [0001] The present invention relates to a flexible display device, and more specifically, to a rollable flexible display device capable of adjusting the length. Background technique [0002] The roll-up flexible display device is composed of a flexible display that is rolled up and stored in the main body casing, and then unfolded for use when necessary. It is not only easy to carry, but also can reduce the size of the device, so it is attracting attention as a next-generation display. [0003] Examples of patent documents related to roll-up flexible display devices include Korean Patent No. 818170 and Korean Laid-Open Patent No. 2009-0076996. Korean Patent No. 818170 discloses a roll-up flexible display device, which is installed on one side or both sides of a PDA, and includes a display drive unit that can be connected and fixed to the PDA. The display drive unit has: a fixing member; A rotating case, which serves as a supporting shaft capable of winding t...
