도 2는 본 발명에 의한 터치패드를 채용한 이동통신 단말기의 개략도로서 이에 도시한 바와 같이, 다이얼링 또는 단문 메시지 전송을 위해 수자, 문자 등을 입력하기 위한 키패드(21)와; 내비게이션을 위해 상기 키패드(21) 상의 일측에 설치된 터치패드(22)와; 사용자를 위한 각종 정보를 표시하고, 상기 터치패드(22)의 조작에 따라 메뉴 화면 상에서 포인터 위치를 변경 표시하는 표시부(23)로 구성한 것으로, 이와 같이 구성한 본 발명의 작용을 상세히 설명하면 다음과 같다.2 is a schematic diagram of a mobile communication terminal employing a touch pad according to the present invention, and as shown therein, a keypad 21 for inputting numbers, characters, etc. for dialing or short message transmission; A touch pad 22 installed on one side of the keypad 21 for navigation; The display unit 23 displays various information for the user and changes the pointer position on the menu screen according to the manipulation of the touch pad 22. The operation of the present invention configured as described above will be described in detail as follows. .

키패드(21)의 상측에 내비게이션을 위한 터치패드(22)가 설치되어 있는 것을 알 수 있다. 상기 키패드(21)는 여러 층의 물질을 포함하고 있는데, 최상층이 손가락으로 접촉되는 패드이고, 아주 얇은 절연체로 구분되어 있는 바로 아래 층은 수평 및 수직 전극봉이 가로와 세로 방향으로 배열되어 격자 모양을 형성하고 있으며, 그 아래 층은 전극봉 층이 연결된 회로판이다. 상기 전극봉이 있는 층은 일정한 교류에 의해 충전되는데, 손가락에 의해 그 전극봉 격자에 일정 압력이 가해지면 전류가 차단되고, 그 상태가 상기 회로판에 의해 감지된다. 패드에 손가락이 맨 처음 접촉한 위치는 계속되는 손가락의 움직임을 파악하기 위해 기록된다.It can be seen that the touch pad 22 for navigation is provided above the keypad 21. The keypad 21 includes several layers of material, and the uppermost layer is a pad contacted by a finger, and a layer just below the thin insulator has horizontal and vertical electrodes arranged horizontally and vertically to form a lattice shape. The lower layer is a circuit board to which the electrode layer is connected. The electrode layer is charged by a constant alternating current, when a certain pressure is applied to the electrode grid by a finger, the current is cut off, and the state is sensed by the circuit board. The position of the first contact of the finger with the pad is recorded to track the continued movement of the finger.

한편, 단말기의 파워가 온되면 표시부(23)에 메인 엘씨디 창이 디스플레이되고, 이때 아이들(idle) 상태임을 디스플레이한다.On the other hand, when the power of the terminal is turned on, the main LCD window is displayed on the display unit 23, and this time, it displays that the idle state.

이와 같은 상태에서 사용자가 메뉴키를 누르면 메뉴화면이 디스플레이되고, 그 메뉴화면 상에 포인터(23A)가 디스플레이된다. 이때부터 사용자는 터치패드(22)를 이용하여 메뉴를 검색하거나 여러 메뉴 중에서 원하는 메뉴를 선택할 수 있게된다.In this state, when the user presses the menu key, the menu screen is displayed, and the pointer 23A is displayed on the menu screen. From this point, the user can search for a menu using the touch pad 22 or select a desired menu from among various menus.

이때, 사용자는 단말기를 한 손으로 잡고 엄지손가락으로 터치패드(22)를 조작하여 작업을 수행할 수 있으며, 상기 포인터(23A)를 움직여 그림 편집 등의 기능을 수행할 수 있다. 이를 위해 터치패드(22)의 하부에 터치패드(22)의 터치 상태를 감지할 수 있는 센서가 구비되고, 이를 통해 출력되는 위치 정보를 분석하여 포인터(23A)의 표시 위치를 변경하게 된다.In this case, the user may hold the terminal with one hand and operate the touch pad 22 with his or her thumb, and perform a function such as picture editing by moving the pointer 23A. To this end, a sensor for detecting a touch state of the touch pad 22 is provided under the touch pad 22, and the display position of the pointer 23A is changed by analyzing the position information output through the touch pad 22.

이상에서 상세히 설명한 바와 같이 본 발명은 이동통신 단말기에 내비게이션용 터치패드를 채용함으로써, 메뉴 검색 및 선택 등의 기능을 보다 편리하게 수행할 수 있는 효과가 있다.As described in detail above, the present invention employs a touch pad for navigation in a mobile communication terminal, thereby making it possible to more conveniently perform functions such as menu search and selection.
