The elastic driving body that is connected by the connection of the connecting groove and applies semi-automatic driving force to the folding of the folding hinge is composed of the first driving unit in the center and the second driving units on the left and right, and the shaft is not used at the bottom of the folding hinge. It relates to a folding hinge for a foldable device having a configuration that covers the internal structure of the folding hinge by installing a lower cover part.
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.
