Abstract

본 발명은 장탈착가능한 디스플레이 장치를 위한 인터페이스 장치에 관한 것으로서, 디스플레이 장치내에 있으며, 서로 연결된 두 개 핀을 포함하여 제1콘넥터와 연결되며, 제1콘넥터의 서로 연결된 두개의 핀과 대응되는 핀 중 하나는 기준전위와 연결되고, 다른 하나는 전원과 연결된 제2콘넥터; 제2콘넥터의 전원과 연결된 핀을 입력으로 하여, 디스플레이 장치의 장착 및 탈착을 감지하는 장탈착 감지부; 및 마이크로프로세서로부터 디스플레이 장치로 전달되는 어드레스를 버퍼링하고, 장탈착감지부로부터 디스플레이 장치가 탈착되었을 경우에는 마이크로프로세서의 어드레스를 출력하지 않고 장착되었을 경우에는 마이크로세서의 어드레스를 출력하지 않고 장착되었을 경우에는 어드레스를 출력하는 어드레스버퍼를 포함함을 특징으로 한다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an interface device for a detachable display device. The present invention relates to an interface device for a detachable display device. A second connector connected to the reference potential and the other connected to a power source; A desorption detection unit detecting input and detachment of a display device by inputting a pin connected to a power source of a second connector; And buffer the address transferred from the microprocessor to the display device, and when the display device is detached from the long attachment / detection unit, when the device is mounted without outputting the address of the microprocessor. And an address buffer for outputting an address.

본 발명에 의하면 시스템의 단가 및 전원소모를 줄일 수 있으며, 탈착시 디스플레이 장치로 입력되는 마이크로프로세서의 신호를 시스템 첫단에서 막음으로 잡음제거를 할 수 있다.According to the present invention, the unit cost and power consumption of the system can be reduced, and noise can be removed by blocking the signal of the microprocessor inputted to the display device at the first stage of the system.
