Description

휴대용단말기의 듀얼타입 엘시디 장치{APPARATUS OF DUAL TYPE LCD OF MOBILE PHONE}Dual type LCD device of portable terminal {APPARATUS OF DUAL TYPE LCD OF MOBILE PHONE}

본 발명은 휴대용단말기에 관한 것으로서, 특히 하나의 엘시디를 이용하여 듀얼폴더의 형태로 이용하기 위한 휴대용단말기의 듀얼타입 엘시디 장치에 관한 것이다The present invention relates to a portable terminal, and more particularly, to a dual type LCD device of a portable terminal for use in the form of a dual folder using one LCD.

휴대용단말기는 소형화, 경량화 되어가고 있고, 또한 화상통화까지 가능하게 되었을 뿐만 아니라 근거리에서 선이 없이도 데이터와 음성을 전송할 수 있는 근거리 무선통신 기술인 블루투스(Bluetooth)의 적용으로 근거리에서 휴대용단말기를 원격으로 조정할 수 있도록 비약적인 발전을 이루어 가고 있다.Handheld terminals are becoming smaller and lighter, and they are able to make video calls as well as remotely control portable terminals at short distances through the application of Bluetooth, a short-range wireless communication technology that can transmit data and voice without a line at a short distance. A leap forward is being made.

이러한 발전은 휴대용단말기의 이용자에게 보다 편리한 휴대 및 이용기능을 제공함으로서 각광을 받고 있다. 휴대폰의 소형화 및 경량화에 있어서는 휴대용단말기에 사용되는 전자부품의 소형화 및 경량화 못지 않게 중요한 것이 휴대폰의 기본적 구조 형태이다. 현재까지 개발 및 판매되고 있는 휴대용단말기들 중에 보편화된 형태의 하나가 폴더타입(Folder-type) 휴대용단말기이다.These developments are in the limelight by providing more convenient portable and use functions for users of portable terminals. In the miniaturization and light weight of a cellular phone, the basic structural form of the cellular phone is equally important as the miniaturization and lightweight of electronic components used in portable terminals. Among the portable terminals that have been developed and sold to date, one of the most popular types is a folder-type portable terminal.

폴더형 휴대용단말기는 폴더가 본체에 장착된 키패드를 보호하여 키의 오 작동을 방지하고, 통화모드시 통화중의 음의 반사판 역할을 수행하여 음을 모아주며, 폴더에 스피커장치나 엘시디창을 설치할 수 있기 때문에 본체 소형화에 대단히 유리하다.The folder type portable terminal protects the keypad mounted on the main body to prevent the malfunction of the keys, collects the sound by acting as a reflector of the sound during the call mode, and installs a speaker device or LCD window in the folder. It is very advantageous for miniaturizing the main body.

이하, 종래의 휴대용단말기에 대해 도시한 도면을 통하여 설명하면 다음과같다.Hereinafter, the conventional portable terminal will be described with reference to the accompanying drawings.

도 1은 폴더형 휴대용단말기의 개방상태의 사시도이고, 도 1에서 도시한 바와 같이, 종래의 폴더형 휴대용단말기(100)는 크게 두 부분으로 구성되며, 본체부(110)와 폴더부(120), 그리고 본체부(110) 상부면 일단에 복개 가능하게 폴더부(120)가 힌지 결합되도록 구성된다.1 is a perspective view of an open state of a clamshell portable terminal, and as shown in FIG. 1, a conventional clamshell portable terminal 100 is largely composed of two parts, a main body 110 and a clamshell 120. And, the folder portion 120 is hingedly coupled to one end of the upper surface of the main body portion 110.

상기 본체부(110)는 데이터를 입력하기 위한 키패드(111)와 그 하부에 음성신호를 전송하기 위한 마이크(112)를 포함하도록 구성된다.The main body unit 110 is configured to include a keypad 111 for inputting data and a microphone 112 for transmitting a voice signal thereunder.

상기 폴더부(120)는 소리를 듣기 위한 스피커부(121)와 상기 키패드(111)의 조작에 따른 운용상태를 보이도록 엘시디(122)를 포함하여 구성된다.The folder unit 120 is configured to include an LCD 122 to show the operating state according to the operation of the speaker unit 121 and the keypad 111 for listening to the sound.

이러한 폴더형 휴대용단말기(100)는 시간 및 휴대용단말기의 상태를 보기 위서 폴더부(120)를 항상 열어야 하는 불편함을 보완하기 위하여, 폴더부(120)의 외표면에 시간과 휴대용단말기의 상태를 보이기 외부엘시디를 추가로 부착한 듀얼폴더형 휴대용단말기를 사용하게 되었다.In order to compensate for the inconvenience of having to always open the folder unit 120 in order to view the time and the state of the portable terminal, the clamshell portable terminal 100 displays the time and state of the portable terminal on the outer surface of the folder unit 120. The dual folder portable terminal with an additional external LCD is now available.

도 2는 종래의 듀얼폴더 휴대용단말기의 개방상태의 사시도 이고, 도 4는 종래의 듀얼폴더 휴대용단말기의 닫힘상태의 사시도이다.Figure 2 is a perspective view of the open state of a conventional dual-folder portable terminal, Figure 4 is a perspective view of a closed state of a conventional dual-folder portable terminal.

도 2와 도 3에서 도시한 바와 같이, 종래의 듀얼폴더 휴대용단말기(200)는 본체부(210)와 폴더부(220), 그리고 본체부(210)의 상부면 일단에 복개 가능하게 폴더부(220)가 힌지 결합되도록 구성된다.As shown in Figure 2 and 3, the conventional dual-folder portable terminal 200 is a body portion 210, the folder portion 220, and the folder portion (1) to be covered on one end of the upper surface of the body portion 210 ( 220 is configured to be hinged.

상기 본체부(210)는 데이터를 입력하기 위한 다수개의 키패드(211)와 그 하부에 음성신호를 전송하기 위한 마이크(212)를 포함하도록 구성된다.The main body 210 is configured to include a plurality of keypads 211 for inputting data and a microphone 212 for transmitting a voice signal thereunder.

상기 폴더부(220)는 소리를 듣기 위한 스피커부(221)와 폴더부(220)가 닫힌 상태에서 휴대용단말기의 시간과 수신상태를 보이기 위한 외부엘시디(223)와, 열린 상태에서 상기 키패드(211)의 조작에 의한 운용상태를 보이도록 내부엘시디(222)를 포함하여 구성된다.The folder unit 220 is a speaker unit 221 for listening to sound and an external LCD 223 for showing the time and reception state of the portable terminal in a state in which the folder unit 220 is closed, and the keypad 211 in an open state. It is configured to include an internal LCD (222) to show the operating state by the operation of the).

이러한, 종래의 듀얼폴더 휴대용단말기(200)의 경우 폴더부(220)의 내부와 외부 표면에 엘시디(222, 223)를 두 개 달아야함으로 폴더부(220)의 두께가 두꺼워지고 무거워져서 소형경량화에 불리해지고, 이에 따른 추가 비용이 발생하여 제조원가가 증대된다는 문제점이 있다.In the case of the conventional dual-folder portable terminal 200, two LCDs 222 and 223 should be attached to the inner and outer surfaces of the folder unit 220 so that the thickness of the folder unit 220 becomes thick and heavy so that the compact and lightweight There is a disadvantage that the additional cost is generated thereby increasing the manufacturing cost.

상기의 문제점을 보완하기 위하여 폴더부가 본체부의 상부면을 열리고 닫힌 상태 모두 휴대용 단말기의 운용상태를 보이기 위해 폴더부를 접혀 개방되는 접철식으로 하고, 폴더부의 외표면에 하나의 엘시디를 장착하여 폴더형 휴대용단말기와 같이 전체적으로 키패드를 모두 가릴 수 있으며, 듀얼 폴더처럼 외부와 내부의 엘시디 기능을 하나의 엘시디로 수행할 수 있도록 한 것이다.In order to supplement the above problems, the folder part is opened and closed in a state where both the open and closed states of the folder part are folded to open the folder part to show the operating state of the portable terminal, and one LCD is mounted on the outer surface of the folder part. The entire keypad can be covered as shown in the figure, and the external and internal LCD functions as a single folder can be performed as a dual folder.
