Abstract

The present invention relates to a foldable hinge module installed in a foldable display device, wherein a folding support module for supporting the folding of a joint part is provided inside the joint part consisting of a plurality of joints such that joints on both sides simultaneously operate at the same angle with respect to a central joint while the joint part is performing a folding or unfolding operation, thus preventing damage to a foldable display panel provided on the joint part, and since all constituent parts of the folding support module are hidden inside the joint part, no damage to the folding support module outside the foldable display device occurs, and thus, the durability of foldable display devices such as smartphones is improved.

Description

폴더블 디스플레이 디바이스에 설치되는 접히는 힌지모듈Folding hinge module installed on a foldable display device

본 발명은 폴더블 디스플레이 디바이스에 설치되는 접히는 힌지모듈로서, 더욱 자세히 설명하면, 다수개의 관절로 구성된 관절부의 안쪽에 내측에 관절부의 폴딩을 지지하는 폴딩지지모듈이 설치되어 관절부가 접히거나 펼쳐지는 동작을 하는 동안에 중앙관절을 중심으로 양측의 관절들이 동시에 동일한 각도만큼 동작을 하도록 구성되어 관절부상에 설치되는 폴더블 디스플레이 패널의 손상이 방지되고, 폴딩지지모듈의 모든 구성부품들이 관절부의 안쪽에 숨겨져 위치하기 때문에 폴더블 디스플레이 디바이스의 외부에서 폴딩지지모듈이 손상되는 문제가 발생되지 않아서 스마트폰 등의 폴더블 디스플레이 디바이스의 내구성을 형상시키는 것을 특징으로 하는 폴더블 디스플레이 디바이스에 설치되는 접히는 힌지모듈에 관한 것이다.The present invention is a folding hinge module installed in a foldable display device, and in more detail, an operation in which a folding support module supporting folding of the joint part is installed inside the joint part composed of a plurality of joints to fold or unfold the joint part. During operation, the joints on both sides around the central joint are configured to operate at the same angle at the same time, preventing damage to the foldable display panel installed on the joint, and all components of the folding support module are hidden inside the joint. Therefore, it relates to a folding hinge module installed in a foldable display device, characterized in that the folding support module is not damaged from the outside of the foldable display device, thereby shaping the durability of a foldable display device such as a smartphone. .

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.The 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 a picture or a video through a camera, a function of recording a voice, a function of playing a music file through a speaker system, and a function of displaying an image or video.

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 to play a game, while others are implemented as multimedia devices. Furthermore, 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.In addition to the above functions, efforts are being made to support and increase the functions of the current mobile terminal. The above-described efforts include not only changes and improvement of 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, in a mobile terminal, a display module displays information processed by the mobile terminal. For example, when the mobile terminal is in a call mode, a user interface (UI) or a graphical user interface (GUI) 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 photographing mode, a photographed or/and received image, 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. ), etc.

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 studied 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, until the development of the flexible display is in progress and its use is activated in earnest, a transitional form will be used a lot, and this form will not be very different from the current terminal structure. In addition, when the currently developed flexible display is used in a mobile terminal, the necessity of describing the usage type and the protection method thereof arises.
