Abstract

The present invention relates to an in-folding hinge structure for a foldable type display apparatus, in which a pair of wing panels of the present invention are arranged so that facing edges are arranged as close to each other as possible, while an in-folding hinge device for a foldable type display apparatus is fully unfolded. Therefore, even when a user pushes a portion where the pair of wing panels face each other with his/her finger, a dent in a flexible display panel does not occur.

Description

접이식 디스플레이장치용 인폴딩 힌지구조In-folding hinge structure for foldable display device
본 발명은 접이식 디스플레이장치용 인폴딩 힌지구조에 관한 것으로, 더욱 자세히 설명하면, 본 발명에 따른 접이식 디스플레이장치용 인폴딩 힌지장치가 전부 펼쳐진 상태에서 본 발명의 한쌍의 윙패널은 마주보는 모서리가 서로 최대한 근접하게 배치되고, 따라서 한쌍의 윙패널이 서로 마주하는 부분을 사용자가 손가락으로 누르더라도 플렉서블 디스플레이패널이 움푹 함몰되는 현상은 발생하지 않는 것을 특징으로 하는 접이식 디스플레이장치용 인폴딩 힌지구조에 관한 것이다.The present invention relates to an in-folding hinge structure for a foldable display device, and more specifically, in a fully unfolded state of the in-folding hinge device for a foldable display device according to the present invention, a pair of wing panels of the present invention have opposite corners It relates to an in-folding hinge structure for a foldable display device, characterized in that it is arranged as close as possible, and therefore, even if a user presses a portion where a pair of wing panels face each other with a finger, a phenomenon in which the flexible display panel is not depressed occurs. .
이동 단말기는 다양한 기능을 수행할 수 있도록 구성될 수 있다. 그러한 다양한 기능들의 예로 데이터 및 음성통신 기능, 카메라를 통해 사진이나 동영상을 촬영하는 기능, 음성 저장 기능, 스피커 시스템을 통한 음악 파일의 재생 기능, 이미지나 비디오의 디스플레이 기능 등이 있다.A mobile terminal may be configured to perform various functions. Examples of such various functions include a data and voice communication function, a function of taking pictures or videos through a camera, a function of recording voice, a function of playing music files through a speaker system, and a function of displaying images or videos.
일부 이동 단말기는 게임을 실행할 수 있는 추가적 기능을 포함하고, 다른 일부 이동 단말기는 멀티미디어 기기로서 구현되기도 한다. 더욱이 최근의 이동단말기는 방송이나 멀티캐스트(multicast) 신호를 수신하여 비디오나 텔레비전 프로그램을 시청할 수 있다.Some mobile terminals include an additional function for playing games, and some other mobile terminals are implemented as multimedia devices. Moreover, recent mobile terminals can watch video or television programs by receiving broadcast or multicast signals.
상기 기능에 부가하여 현재 이동 단말기의 기능을 지지하고 증대하기 위한 노력들이 계속되고 있다. 상술한 노력은 이동 단말기를 형성하는 구조적인 구성요소의 변화 및 개량뿐만 아니라 소프트웨어나 하드웨어의 추가 및 개량도 포함한다.Efforts are ongoing to support and augment the capabilities of current mobile terminals in addition to the above capabilities. The above efforts include not only changes and improvements in structural elements forming the mobile terminal, but also addition and improvement of software or hardware.
일반적으로 이동 단말기에서 디스플레이 모듈은 이동 단말기에서 처리되는 정보를 표시한다. 예를 들어 이동 단말기가 통화 모드인 경우 통화와 관련된 UI(User Interface) 또는 GUI(Graphic User Interface)를 표시한다. In general, a display module in a mobile terminal displays information processed in the mobile terminal. For example, when the mobile terminal is in a call mode, a UI (User Interface) or GUI (Graphic User Interface) related to a call is displayed.
그리고 이동 단말기가 화상 통화 모드 또는 촬영 모드인 경우 촬영 또는/및 수신된 영상 또는 UI, GUI 를 표시한다. 상기 디스플레이 모듈은 액정 디스플레이(liquid crystal display), 박막 트랜지스터 액정 디스플레이(thin film transistor-liquid crystal display), 유기 발광 다이오드(organic light-emitting diode), 플렉시블 디스플레이(flexible display), 3차원 디스플레이(3D display) 등으로 구성될 수 있다.In addition, when the mobile terminal is in a video call mode or a shooting mode, a photographed or/and received video, UI, or GUI is displayed. The display module includes a liquid crystal display, a thin film transistor-liquid crystal display, an organic light-emitting diode, a flexible display, and a 3D display. ) and the like.
그 중에서 플렉시블 디스플레이(flexible display)(또는 플렉시블 LCD)는 모양을 마음대로 변형할 수 있다는 장점 때문에 현재 그 연구가 본격화되고 있다. 하지만, 현재 공상영화에서 보여주는 것처럼 완전히 종이와 같은 디스플레이를 두루마리처럼 가지고 다니기까지는 앞으로 많은 시간이 걸릴 것으로 보여진다.Among them, a flexible display (or flexible LCD) is currently being researched in earnest because of the advantage of being able to change its shape at will. However, it seems that it will take a lot of time in the future to carry a completely paper-like display like a scroll, as shown in current science fiction films.
따라서, 플렉시블 디스플레이의 개발이 진행되어 사용이 본격적으로 활성화되기 전까지는 과도기적 형태가 많이 사용될 것이며 이 형태는 현재의 단말기 구조와 크게 다르지 않을 것이다. 또한, 현재 개발되고 있는 플렉시블 디스플레이가 이동 단말기에 사용될 때 그 사용 형태 및 그 보호방법에 대하여 기술할 필요성이 대두된다.Therefore, the transitional form will be used a lot until the flexible display is developed and used in earnest, and this form will not be significantly different from the current terminal structure. In addition, when a flexible display currently being developed is used in a mobile terminal, there is a need to describe its use form and its protection method.
