Abstract

본 발명은 각종 디스플레이 장치에서 사용자 인터페이스에 쓰이는 온 스크린 장치에 관한 것으로, 특히 문자와 화면을 겹쳐서 나타내는 장치 및 방법에 관한 것이다. 즉, 온 스크린 장치를 동작시킴에 있어서, 스위칭 동작부분을 제거하고 가산기를 사용함으로써 온 스크린 문자와 화면을 동시에 출력할 수 있도록 하여 텔레비젼, 비디오, 엘시디-투영기(LCD-Projector) 등의 디스플레이(CRT, LCD판넬)를 사용하는 모든 제품에 적용할 수 있어서 매우 유용하다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an on-screen device used in a user interface in various display devices, and more particularly, to an apparatus and method for superimposing characters and a screen. In other words, in operating the on-screen device, by removing the switching operation part and using an adder, it is possible to simultaneously output the on-screen text and the screen so that a display (CRT) of a television, a video, an LCD-projector, etc. It is very useful because it can be applied to all products using LCD panel).

Claims

Characters of red (R), green (G), and blue (B) that receive H.sync and V.sync signals and output them to the adder are displayed on the screen with on-screen function. A timing metering microcomputer 1 for positioning a character at the time of output; R adder having an input terminal I1 for receiving a red (R) video signal, an input terminal I2 for receiving a text signal, and a terminal Rout for combining (adding) and outputting the signals input from each terminal ( 2) and; G adder having an input terminal I1 for receiving a green (G) video signal, an input terminal I2 for receiving a text signal, and an output terminal (Gout) for adding (adding) and outputting the signals input from each terminal. (2); B adder having an input terminal I1 for receiving a blue (B) video signal, an input terminal I2 for receiving a text signal, and a terminal Bout for adding (adding) and outputting the signals input from each terminal ( 2) overlay device of the on-screen device, characterized in that configured to include.

A method of outputting a character on a screen, wherein the text signal and the video signal are selectively added for each color and outputted so that the video signal of the portion where the character is output is output without overlapping with the character. Way.
