Description

액정표시장치의 화면위치 제어회로Screen position control circuit of LCD

본 내용은 요부공개 건이므로 전문내용을 수록하지 않았음As this is a public information case, the full text was not included.

제1도는 본 발명의 일실시예에 있어서의 액정표시 장치의 화면위치를 제어하는 회로 블록도.1 is a circuit block diagram for controlling the screen position of a liquid crystal display device according to an embodiment of the present invention.

제2도는 그 제어 프로그램의 일례를 도시한 플루오 차아트.2 is a fluorocharart showing an example of the control program.

제3도는 버퍼를 인에이블시키는 스캔펄스 파형도.3 is a scan pulse waveform diagram for enabling a buffer.

Claims (1)

표시화면의 위치를 제어하는 액정표시장치의 화면위치 제어회로에 있어서, 상기 화면의 위치를 상하 및 좌우 방향으로 제어하는 프로그램이 격납되어 있는 제1의 메모리 수단과, 입력단자에 신호가 입력되었을 경우, 복수개의 스위치의 온·오프 상태에 따라 버퍼의 입력신호를 판독해서 상기 제1의 메모리 수단에 격납된 프로그램을 판독하여 수평 및 수직방향의 화면 위치 제어용 데이터를 버퍼에 각각 출력하는 CPU와, 상기 버퍼에 입력된 상기 화면 제어용 데이터를 출력하도록 스캔펄스를 출력시키며 상기 화면 제어용 데이터를 수신하여 퍼스널 컴퓨터 화면표시 출력의 비데오 신호를 8비트의로직데이터로 변환하여 수평 및 수직신호와 동기시켜서 화면신호를 출력하는 LCD제어수단과, 상기의 데이터를 받아 LCD표시장치를 구동시키는 에노드 구동회로와 컴는 구동회로를 갖춘 것을 특징으로 하는 액정표시장치의 화면위치 제어회로.In a screen position control circuit of a liquid crystal display device for controlling the position of a display screen, when a signal is inputted to a first memory means in which a program for controlling the position of the screen in up, down, left and right directions is stored, and an input terminal; A CPU which reads an input signal of a buffer in accordance with an on / off state of a plurality of switches, reads a program stored in the first memory means, and outputs horizontal and vertical screen position control data to the buffer, respectively; A scan pulse is output to output the screen control data input to the buffer, and the screen control data is received to convert the video signal of the personal computer screen display output into 8-bit logic data and synchronize the screen signal with the horizontal and vertical signals. LCD control means for outputting and an anode driving circuit for driving the LCD display device by receiving the above data Low and com is a screen position control circuit of the liquid crystal display device characterized in that it comprises a drive circuit. ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
