Abstract

본 발명은 휴대형 개인 정보 단말기에 외부 화면 표시 장치(CRT, OHP)를 연결하였을 때 그 외부 화면 표시 장치의 전화면에 걸쳐서 영상 정보가 표시될 수 있도록 한 휴대형 개인 정보 단말기의 듀얼 디스플레이 장치에 관한 것으로서, 종래의 소형 사이즈의 LCD를 장착한 휴대형 개인 정보 단말기 제품들의 LCD사이즈는 전화면 표시가 가능한 CRT나 OHP처럼 전화면을 나타내지 못한다.The present invention relates to a dual display device of a portable personal digital assistant in which image information can be displayed over the full screen of the external screen display when the external screen display device (CRT, OHP) is connected to the portable personal digital assistant. However, the LCD size of the portable personal digital assistant products equipped with the conventional small size LCD does not display the full screen like CRT or OHP capable of full screen display.

본 발명은 디스플레이할 영상신호를 자체 LCD표시와 외부 전화면 표시의 모드에 따라 영상 기억수단(2)에 저장 및 출력하는 제어수단(1)과, LCD화면 사이즈에 대응하는 영역의 영상신호를 저장하고 또 출력하는 제1의 영상 기억부(2a)와, 전화면 디스플레이를 위한 나머지 화면 영역에 해당하는 영상신호를 저장하고 또 출력하는 제2의 영상 기억부(2b)를 포함하는 영상 기억수단(2)과, 상기 제어수단(1)의 제어를 받아 상기의 영상 기억 수단(2)에서 출력되는 전화면 사이즈의 영상데이타를 아날로그 신호로 변환하여 외부의 영상표시수단에 공급하는 D/A변환수단(3)과, 상기 제어수단(1)의 제어를 받아, 상기 영상 기억수단(2)의 제1의 영상 기억부(2a)의 영상신호와 제2의 영상 기억부(2b)의 영상신호가 선택적으로 자체 영상표시수단에 공급되게 제어하는 데이타 출력 선택수단(5)를 구비하여, LCD화면과 전화면 표시의 듀얼 디스플레이가 가능하도록 한 휴대형 개인 정보 단말기의 듀얼 디스플레이 장치를 제공 한다.The present invention stores the control means (1) for storing and outputting the video signal to be displayed in the video storage means (2) according to the mode of its own LCD display and external full screen display, and the video signal in the area corresponding to the LCD screen size. And a second video storage unit 2b for storing and outputting a video signal corresponding to the remaining screen area for full-screen display. 2) and D / A conversion means for converting the video data of the full screen size output from the video storage means 2 into an analog signal under the control of the control means 1 and supplying it to an external video display means. (3) and under the control of the control means (1), the video signal of the first video memory (2a) of the video memory means (2a) and the video signal of the second video memory (2b) Data to be selectively supplied to its own image display means And a selection unit (5) force, and provides a dual display device of a portable personal information terminal, a dual display of the LCD display and full-screen display is possible.
