본 발명은 외부에 기능키가 마련된 휴대전화기에 관한 것으로, 더욱 자세하게는 두개의 엘씨디(LCD: Liquid Crystal Display)를 갖는 폴더형 휴대 전화기에서 전화기가 접혀진 상태에서도 기능키를 조작하여 외측의 LCD를 통해 디스플레이 되는 정보를 제어할 수 있도록 한 휴대전화기에 관한 것이다.The present invention relates to a mobile phone provided with a function key on the outside, and more particularly, in a folding mobile phone having two LCDs (liquid crystal display), the function key is operated even when the phone is folded, through an external LCD. The present invention relates to a mobile phone which enables to control the displayed information.

폴더형 휴대전화기에서 듀얼 LCD를 채용하는 것이 일반화 되고 있는데, 이와 같은 휴대전화기에 대한 내용이 대한민국 등록특허 274298호에 개시되어 있다. 이와 같은 듀얼 LCD를 갖는 폴더형 휴대 전화기에 있어서, 외측의 LCD에는 주로 발신자 전화번호와 시간/날짜, 수신 감도, 배터리 상태 등을 나타내는 간단한 정보가 표시되고, 내측의 LCD에는 사용자 데이터가 표시된다. 그리고, 소모 전력을 최소로 하기 위하여 전화기가 접혀져 있는 경우에는, 내측의 LCD는 오프(off)되고, 외측의 LCD는 온(on)상태로 되며, 반대로, 휴대전화기가 개방된 상태에서는 외측의 LCD가 오프되고, 내측의 LCD가 온(on)되어 단말기 상태정보를 표시할 수 있게 한다.It is common to employ a dual LCD in a folding mobile phone, the contents of such a mobile phone is disclosed in Korean Patent No. 274298. In such a folding-type mobile telephone having a dual LCD, the outer LCD mainly displays the caller's telephone number and simple information indicating the time / date, reception sensitivity, battery status, and the like, and the user data is displayed on the inner LCD. When the phone is folded to minimize power consumption, the LCD on the inside is turned off, and the LCD on the outside is turned on. On the contrary, when the phone is open, the LCD on the outside is opened. Is turned off, and the inner LCD is turned on to display terminal status information.

하지만, 이와 같은 휴대 전화기에서는 사용자가 수신된 메시지를 확인하고자 하는 경우에도 반드시 휴대전화기를 개방한 상태에서만 가능하다는 단점이 있다.However, such a mobile phone has a disadvantage in that it is possible only when the user wants to check a received message only when the mobile phone is open.

따라서, 본 발명은 듀얼 LCD를 갖는 폴더형 휴대 전화기에서 전화기를 개방하지 않고도 외측의 LCD를 통해 수신된 메시지를 확인하거나 저장된 메시지를 전송할 수 있고, 무선 인터넷 접속 등이 가능한 휴대전화기를 제공하는데 그 목적이 있다.Accordingly, an object of the present invention is to provide a mobile phone capable of confirming a message received through an external LCD or transmitting a stored message and opening a wireless Internet connection without opening the phone in a folding portable phone having a dual LCD. There is this.

도1은 본 발명에 따른 휴대용 전화기의 사시도.1 is a perspective view of a portable telephone according to the present invention.

도2는 본 발명에 따른 휴대용 전화기의 개방 상태의 사시도.Figure 2 is a perspective view of the open state of the portable telephone according to the present invention.

상기 목적을 달성하기 위한 본 발명은, 내측에 제1 표시부(LCD)와 숫자키 제1 기능키들이 마련되고, 외측에 제2 표시부(LCD)가 마련된 폴더형 휴대전화기에 있어서, 상기 제2 표시부가 마련된 외측에는 제2 기능키가 마련되어, 휴대전화기를 개방하지 않고도 상기 제2 표시부를 통해 디스플레이 되는 정보를 제어할 수 있도록 한 것을 특징으로 한다.In the present invention for achieving the above object, in the foldable cellular phone provided with a first display (LCD) and the numeric key first function keys on the inside, a second display (LCD) on the outside, the second display portion A second function key is provided on the outer side, and the information displayed on the second display unit can be controlled without opening the cellular phone.

이하, 첨부된 도면을 참조하여 본 발명에 따른 바람직한 실시 예를 상세히 설명한다.Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

도1은 본 발명에 따른 폴더형 휴대전화기의 사시도이고, 도2는 본 발명에 따른 폴더형 휴대전화기의 개방된 상태에서의 사시도이다.1 is a perspective view of a folding cellular phone according to the present invention, and FIG. 2 is a perspective view in an open state of a folding cellular phone according to the present invention.

도면에 도시된 바와 같이, 폴더형 휴대전화기가 접혀진 상태에서도 각종 정보를 디스플레이하기 위해, 내측에 마련된 제1 LCD(1)와 동일한 크기를 가지는 제2 LCD(1')가 외측에 마련된다. 또한, 폴더형 휴대전화기가 접혀진 상태에서 디스플레이 되는 정보를 제어하기 위한 제2 기능키(2')들이 외측에 마련된다. 그리고, 폴더형 휴대전화기의 일 측면에는 외측에 마련된 제2 기능키(2')들을 잠금하거나 잠금해제하기 위한 잠금키(3)가 마련된다.As shown in the figure, in order to display various types of information even when the folding cellular phone is folded, a second LCD 1 'having the same size as the first LCD 1 provided inside is provided on the outside. In addition, second function keys 2 'are provided on the outside for controlling the information displayed in the folded state of the cellular phone. In addition, a lock key 3 for locking or releasing the second function keys 2 ′ provided at an outer side of the clamshell phone is provided.

이와 같은 구성을 가지는 본 발명에 따른 휴대전화기에 대해 보다 구체적으로 살펴보면 다음과 같다.Looking at the mobile phone according to the present invention having such a configuration in more detail as follows.

폴더형 휴대 전화기의 내측에는 종래와 같이 제1 LCD(1)와 제1 기능키(2)를 포함하는 다수의 키들이 마련되어 있다. 그리고, 도1에 도시된 바와 같이 폴더형 휴대전화기의 외측에는 제2 LCD(1')와 제2 기능키(2')가 마련된다. 또한, 폴더형 휴대전화기의 일 측면에 마련된 잠금키(3)는, 사용자가 폴더형 휴대전화기를 접은 상태로 휴대하고 다니는 중에 제2 기능키(2')가 작동되는 것을 방지하기 위해 마련되는데, 상기 잠금키(3)는 상/하로 슬라이딩되는 키이다.Inside the foldable cellular phone, a plurality of keys including the first LCD 1 and the first function key 2 are provided as in the prior art. As shown in Fig. 1, a second LCD 1 'and a second function key 2' are provided on the outside of the folding cellular phone. In addition, the lock key 3 provided on one side of the folding cellular phone is provided to prevent the second function key 2 'from being operated while the user is carrying the folding cellular phone in a folded state. The lock key 3 is a key sliding up and down.

이와 같은 구성을 갖는 폴더형 휴대전화기에서의 정보를 표시하기 위한 제어동작을 살펴보면 다음과 같다.Looking at the control operation for displaying information in the clamshell mobile phone having such a configuration as follows.

폴더형 휴대전화기가 접혀진 경우에는, 제어부(중앙처리장치로 도시되지 않음)는 잠금키(3)가 잠금상태인지 잠금해제상태인지 확인하여, 잠금상태이면 외측면에 마련된 제2 기능키(2')가 작동되지 않도록 제어하고, 잠금해제상태이면 제2 기능키(2')가 작동되도록 제어한다. 잠금키(3)가 잠금해제상태에서, 메시지가 수신되거나, 인터넷 접속을 하고자 하는 경우에는 폴더형 휴대전화기를 개방하지 않고, 제2 기능키(2')를 조작하여 수신된 메시지를 확인하거나, 인터넷 접속을 수행한다. 이와 같이 제2 LCD(1')를 통해 정보를 표시하다가, 사용자가 폴더형 휴대전화기를 개방하는 경우에는 제2 LCD(1')에 표시되던 정보를 제1 LCD(1)에 그대로 표시하고, 외측의 제2 기능키(2')의 상태를 잠금상태로 전환한다. 그리고, 제2 LCD(1')에는 초기 로고와 같은 다른 정보를 표시한다. 물론, 여기서 종래와 같이 폴더형 휴대전화기가 개방되는 경우에는 제2 LCD를 오프하는 것도 가능할 것이다. 한편, 다시 폴더형 휴대전화기가 접혀지면 제2 LCD(1')에는 초기 정보가 디스플레이 되고, 잠금키(3)의 상태에 따라 외측의 제2 기능키(2')는 잠금되거나 잠금해제된다.When the folding cellular phone is folded, the control unit (not shown by the central processing unit) checks whether the lock key 3 is locked or unlocked, and if it is locked, the second function key 2 ' ) Is operated so that the second function key 2 'is operated when the device is unlocked. When the lock key 3 is in the unlocked state, when a message is received or when the user wants to access the Internet, the received message is operated by operating the second function key 2 'without opening the clamshell-type mobile phone, or Perform internet access. In this way, while the information is displayed through the second LCD 1 ', when the user opens the folding cellular phone, the information displayed on the second LCD 1' is displayed on the first LCD 1 as it is. The state of the outer second function key 2 'is switched to the locked state. Then, other information such as an initial logo is displayed on the second LCD 1 '. Of course, it will be possible to turn off the second LCD when the clamshell cell phone is opened as in the prior art. On the other hand, when the folding cellular phone is folded again, initial information is displayed on the second LCD 1 ', and the outer second function key 2' is locked or unlocked according to the state of the lock key 3.

한편, 전술한 바와 같은 제어부가 제2 LCD(1')에 표시되던 정보를 제1 LCD(1)에 표시하는 방법은 일반적인 기술로, 당업자에 있어 용이하게 실시 할 수 있는 기술이다. 즉, 이와 같은 기술은 제어부가 폴더형 휴대전화기의 현재 상태를 체크하고, 개방이 되면 제2 LCD(1')로 전송되던 정보를 제1 LCD(1)로 절체하여 전송함으로써 간단하게 이루어지는 것으로, 보다 구체적인 설명은 생략한다.On the other hand, the method for displaying the information displayed on the second LCD (1 ') by the control unit as described above on the first LCD (1) is a general technique, which can be easily implemented by those skilled in the art. That is, such a technique is simply performed by the control unit checking the current state of the clamshell mobile phone and transferring the information transmitted to the second LCD 1 'to the first LCD 1 when opened. More detailed description will be omitted.

상기와 같은 본 발명에 의하면, 폴더형 휴대전화기에서 전화기를 개방하지 않고도 수신된 메시지를 확인하거나 인터넷 접속 등을 할 수 있어, 사용자들이 보다 편리하게 휴대전화기를 사용할 수 있는 효과가 있다.According to the present invention as described above, it is possible to check the received message or to connect to the Internet without opening the phone in the clamshell phone, users can use the phone more conveniently.
