Abstract

The present invention relates to a foldable structure which enables folding two folded units together by using a folding unit, and at the same time, is implemented so that, when the two folded units are unfolded, the respective upper surfaces of the two folded units, including between the two folded units, are completely flat.

When a component is referred to as being “connected” to another component, it may be directly connected to the other component, but it should be understood that other components may exist in between. On the other hand, when it is mentioned that a certain element is "directly connected" to another element, it should be understood that the other element does not exist in the middle. Meanwhile, other expressions describing the relationship between elements, that is, “between” and “in between” or “neighboring to” and “directly adjacent to”, etc., should be interpreted similarly.

일 실시 예에서, 플렉시블유닛(150)은, 제1폴더대상유닛(110)과 제2폴더대상유닛(120) 사이를 접었을 때에 제1영역의 상면이 제2영역의 상면과 접하도록 형성할 수 있으며, 이때 제3영역은 제1삽입공간부(111)와 제2삽입공간부(121)양측으로 밀려들어가면서 물방울 형태로 폴딩됨으로써(도 9 참조), 찌그러짐이 발생하지 않고 접히는 부분에도 선이 형성되지 않아 화면 표시 시에 깨끗한 화질을 제공할 수 있다.In one embodiment, the flexible unit 150 may be formed such that the upper surface of the first area is in contact with the upper surface of the second area when the first folder target unit 110 and the second folder target unit 120 are folded. At this time, the third region is folded in the form of a water droplet while being pushed into both sides of the first insertion space 111 and the second insertion space 121 (see FIG. 9 ), so that no distortion occurs and a line is formed in the folded part Therefore, it is possible to provide a clear picture quality when displaying the screen.
상술한 바와 같은 구성을 가진 폴더 구조(100)는, 접철유닛(130)을 이용하여 두 개의 폴더대상유닛(110, 120) 사이를 접을 수 있도록 함과 동시에, 두개의 폴더대상유닛(110, 120) 사이를 펼쳤을 때에 두 개의 폴더대상유닛(110, 120)사이를 포함해서 두 개의 폴더대상유닛(110, 120)의 상면이 완전히 평탄하도록 구현함으로써, 폴더대상유닛(110, 120) 상에 다른 유닛(즉, 플렉시블유닛(150))을 구비시키기 쉬우며, 특히 휘어지거나 접어지는 표시패널(즉, 플렉시블유닛(150) 중플렉시블 표시모듈)을 폴더대상유닛(110, 120) 상에 구비시키더라도 접었을 때에 완전히 접힐 수 있을 뿐만 아니라, 접을 때에도 플렉시블 표시모듈의 찌그러짐이 발생하지 않고 접히는 부분에도 선이 형성되지 않아 화면 표시 시에 깨끗한 화질을 제공할 수 있다.The folder structure 100 having the configuration as described above uses the folding unit 130 to fold between the two folder target units 110 and 120, and at the same time, the two folder target units 110 and 120 ) by implementing such that the top surfaces of the two folder target units 110 and 120 are completely flat, including between the two folder target units 110 and 120, when spread between the other units on the folder target units 110 and 120. (That is, it is easy to provide the flexible unit 150), and in particular, even if a display panel that is bent or folded (that is, a flexible display module among the flexible unit 150) is provided on the folder target units 110 and 120, it would be folded. Not only can it be completely folded when folded, no distortion of the flexible display module occurs even when folded, and no lines are formed on the folded part, so it is possible to provide a clean picture quality when displaying the screen.
