본 발명은 그래픽화면상의 OSD 표시장치에 관한 것으로서, 특히 LCD에 그래픽화면을 뿌려주는 그래픽 IC의 그래픽 스위치 입력단에 OSD의 강제작동신호(Super impose signal)를 연계시켜 그래픽 IC의 소프트웨어가 구동되도록 하여 LCD에 출력되는 지도화면에 OSD 화면이 중첩되도록 하므로서, 네비게이션의 지도화면이나 텔레메틱스의 풀 그래픽화면상에 OSD로 구현된 메뉴바, 문자 등을 중첩 출력할 수 있도록 한 그래픽화면상의 OSD 표시장치에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an OSD display device on a graphic screen. In particular, the software of the graphic IC is driven by linking a super impose signal of the OSD to a graphic switch input of a graphic IC that sprays the graphic screen to the LCD. The present invention relates to an OSD display device on a graphic screen that allows an OSD screen to be superimposed on a map screen displayed on the screen so that the menu bar, texts, and the like implemented on the OSD can be superimposed on a map screen of navigation or a full graphic screen of telematics. .

현재 차량에 탑재되는 에브 시스템은 오디오 및 비디오의 출력 뿐만아니라 네비게이션을 통한 지리정보 출력 또는 차내에서의 통화를 위한 텔레메틱스가 설치되고 있다.Currently, the EV system installed in a vehicle is equipped with telematics not only for outputting audio and video but also for outputting geographical information through navigation or for in-car call.

상기와같은 네비게이션 또는 텔레메틱스에는 그래픽등과같은 화면이 화면상에 출력되도록 LCD에 뿌려주는 그래픽IC가 적용되고 있다.In the above navigation or telematics, a graphic IC is applied to the LCD so that a screen such as a graphic is output on the screen.

종래의 네비게이션 또는 텔레메틱스의 지도화면이나 풀 그래픽화면에서 다른 정보를 보거나 메뉴를 선택하고자 할때 모드 변경을 위한 하드 키이를 사용하여 명령을 수행하였다.When a user wants to view other information or select a menu on a conventional navigation or telematics map screen or a full graphic screen, a command is performed using a hard key for mode change.

그러나, 종래에는 지도화면이나 그래픽화면상에서 메뉴를 선택하거나 다른 정보를 서낵하고자 할때 일일이 하드키이를 조작해야만 하는사용상 번거로움이 가중되는 문제점이 있었다.However, in the related art, when a menu is selected on a map screen or a graphic screen or when other information is to be arranged, there is a problem in that a user has to operate a hard key.

특히 네비게이션의 지도화면상에 목적지를 안내하는 지도화면이 출력되고 있는 상태에서 다른 메뉴를 선택하기 위해서는 운전자가 상체를 움직여 손으로 다른 하드키이를 조작해야만 하므로 이 과정에서 집중력이 흐트러져 교통사고가 발생하게되는 문제점이 있었다.In particular, in order to select a different menu while the map screen for guiding the destination is displayed on the map screen of the navigation, the driver must move the upper body and operate another hard key by hand, thus distracting the concentration and causing traffic accidents. There was a problem.

따라서, 상기 문제점을 해결하기 위한 본 발명은 LCD에 그래픽화면을 뿌려주는 그래픽 IC의 그래픽 스위치 입력단에 OSD의 강제작동신호(Super impose signal)를 연계시켜 그래픽 IC의 소프트웨어가 구동되도록 하여 LCD에 출력되는 지도화면에 OSD 화면이 중첩되도록 하므로서, 네비게이션의 지도화면이나 텔레메틱스의 풀 그래픽화면상에 OSD로 구현된 메뉴바, 문자 등을 중첩 출력할 수 있도록 한 그래픽 화면상의 OSD 표시장치를 제공함을 목적으로 한다.Accordingly, the present invention for solving the above problems is to be connected to the graphic switch input terminal of the graphic IC to spray the graphic screen on the LCD is connected to the super impose signal of the OSD (Super impose signal) to drive the software of the graphics IC is output to the LCD It is an object of the present invention to provide an OSD display device on a graphic screen that allows an OSD screen to be superimposed on a map screen so that the menu bar and texts implemented by the OSD can be superimposed on a navigation map screen or a telematics full graphic screen. .

상기 목적달성을 위한 본 발명은 The present invention for achieving the above object

지도화면이나 풀 그래픽화면을 출력하는 LCD와;An LCD for displaying a map screen or a full graphic screen;

지도화면정보와 메뉴바 및 기능키 등의 OSD 정보를 입력받아 신호처리하여 상기 LCD상에 뿌려주는 그래픽 IC와;A graphic IC which receives map screen information and OSD information such as a menu bar and a function key, processes the signal, and spreads the signal on the LCD;

그래픽IC의 구동을 위한 그래픽스위치신호와 OSD의 적용여부를 제어하는 강제작동신호 중 어느 하나가 하이레벨일때 LCD로 강제작동신호를 출력하여 OSD가 LCD 화면상에 중첩되어 표시되도록 하는 오아게이트와;An oragate for outputting a forced operation signal to the LCD when any one of the graphic switch signal for driving the graphic IC and the forced operation signal for controlling the application of the OSD is at a high level so that the OSD is displayed overlapped on the LCD screen;

상기 강제작동신호의 반전신호와 그래픽스위치신호가 모두 하이일때 그래픽IC를 작동시키는 앤드게이트; 로 구성된 것을 특징으로 한다.An AND gate for operating a graphics IC when both the inverted signal of the forced operation signal and the graphic switch signal are high; Characterized in that consisting of.

이하, 첨부된 도면 도 1 을 참조하여 본 발명의 바람직한 실시예를 설명하면 다음과 같다.Hereinafter, exemplary embodiments of the present invention will be described with reference to the accompanying drawings.

상기 도면에 의하면, 본 발명은 지도정보와 메뉴바 또는 기능키이 등을 표시하기 위한 OSD 정보를 R,G,B 신호로 입력받고, 그 입력된 지도정보와 OSD정보를 서로 중첩시켜 LCD(2)에 출력하는 그래픽IC(1)가 구성된다.According to the drawing, the present invention receives the OSD information for displaying the map information and menu bar or function keys, etc. as R, G, B signals, and superimposed the input map information and OSD information to each other LCD (2) The graphic IC 1 which outputs to is constructed.

상기 그래픽IC(1)는 후설하는 앤드게이트(5)의 출력이 하이일때 작동하여 지도화면에 OSD화면을 중첩시켜 LCD(2) 상에 표시하게된다.The graphic IC 1 is operated when the output of the AND gate 5 to be rearranged is high to superimpose an OSD screen on the map screen and display it on the LCD 2.

한편, 상기 LCD(2)는 그래픽IC(1)로부터 공급되는 지도화면과 OSD화면을 서로 중첩되게 출력한다.On the other hand, the LCD 2 outputs the map screen and the OSD screen supplied from the graphics IC 1 to overlap each other.

상기와같은 회로에는 그래픽IC(1)의 구동을 제어하기 위한 그래픽스위치신호와 상기 OSD정보의 선택적인 출력을 위한 강제작동신호(super impose signal)가 입력되며, 그 입력단에는 그래픽스위치신호 또는 강제작동신호중 어느 하나라도 하이신호일때 LCD(2)로 하이신호를 출력하여 LCD(2)가 작동되도록 하는 오아게이트(3)가 연결된다.A circuit switch signal for controlling the driving of the graphic IC 1 and a super impose signal for selective output of the OSD information are input to the circuit as described above, and a graphic switch signal or a forced operation is input to the input terminal. When any one of the signals is a high signal, an oragate 3 for outputting a high signal to the LCD 2 to operate the LCD 2 is connected.

또한, 상기 그래픽IC(1)의 제어신호 입력단에는 상기 강제작동신호의 반전신호와 그래픽스위치신호가 모두 하이상태일때 그래픽IC(1)의 구동을 위한 하이신호를 출력하는 앤드게이트(5)가 연결된다.In addition, an AND gate 5 for outputting a high signal for driving the graphic IC 1 is connected to the control signal input terminal of the graphic IC 1 when both the inverted signal of the forced operation signal and the graphic switch signal are high. do.

미설명된 도면부호 4 는 상기 강제작동신호를 반전시켜 앤드게이트(5)의 일측입력단으로 공급하는 인버터이다.Unexplained reference numeral 4 is an inverter for inverting the forced operation signal and supplying it to one input terminal of the AND gate 5.

상기 설명과같은 본 발명은 그래픽IC(1)가 작동하여 지도정보와 OSD 정보를 신호처리하여 LCD(2) 화면상에 중첩시켜 출력하므로서, OSD 정보를 메뉴바 또는 기능키의 형태로 출력하여 사용자가 하드키이를 조작하지 않고서도 OSD화면을 통해 다른 기능을 입력할 수 있도록 할 수 있으며, 특히 터치스크린을 사용하는 경우 버튼 기능을 OSD화면으로 구현하여 정보를 보거나 메뉴바로 사용할 수 있게되는 것이다.According to the present invention as described above, the graphics IC 1 operates to signal-map map information and OSD information, and output the superimposed OSD information in the form of a menu bar or a function key while superimposing the information on the LCD 2 screen. It is possible to input other functions through the OSD screen without operating the hard key. Especially, when using the touch screen, the button function is implemented as the OSD screen to view information or to use the menu bar.

이상에서 설명한 바와같이 본 발명은 LCD에 그래픽화면을 뿌려주는 그래픽 IC의 그래픽 스위치 입력단에 OSD의 강제작동신호(Super impose signal)를 연계시켜 그래픽 IC의 소프트웨어가 구동되도록 하여 LCD에 출력되는 지도화면에 OSD 화 면이 중첩되도록 하므로서, 네비게이션의 지도화면이나 텔레메틱스의 풀 그래픽화면상에 OSD로 구현된 메뉴바, 문자 등을 중첩 출력할 수 있도록 한 그래픽화면상의 OSD 표시장치을 제공하는 효과를 기대할 수 있다.As described above, the present invention connects the super impose signal of the OSD to the graphic switch input terminal of the graphic IC that sprays the graphic screen to the LCD so that the software of the graphic IC is driven to the map screen output to the LCD. By overlaying the OSD screen, it is possible to expect an effect of providing an OSD display device on the graphic screen to superimpose and output the menu bar, characters, etc. implemented by the OSD on the navigation map screen or telematics full graphic screen.
