Claims (1)

키보드(1)에 의해 수평 어드레스(address)가 입력되는 제어회로(2)에 디코더회로(4)를 연결함과 동시에 수평동기 신호와 수직 동기 신호가 입력되는 클럭 카운터회로(3)를 디코더회로(4)에 각각 접속하고 상기 디코더회로(4) 각 단의 출력을 수평 전류 버퍼회로(5)에 연결하며, 또한 연속 데이타 신호와 클럭 신호가 인가되는 쉬프터 레지스터(9)의 출력을 래치회로(8)에 접속하고(이때 래치회로(8)에 수평동기 신호가 인가되도록 한다) 상기 래치회로(8)의 출력을 디스플레이 이네이블 신호가 인가되는 수직 전류 버퍼회로(7)에 연결하며 수평 및 수직전류 버퍼회로(5,7)의 출력단을 LED 매트리스 회로(6)에 각각 접속하여서 된 것을 특징으로 하는 CRT 제어회로를 이용한 수평 주사 방식의 LED 표시장치.The decoder circuit 4 is connected to a control circuit 2 to which a horizontal address is input by the keyboard 1 and a clock counter circuit 3 to which a horizontal synchronization signal and a vertical synchronization signal are input. 4), the output of each stage of the decoder circuit 4 is connected to the horizontal current buffer circuit 5, and the output of the shifter register 9 to which the continuous data signal and the clock signal are applied is latch circuit 8 (The horizontal synchronization signal is applied to the latch circuit 8) and the output of the latch circuit 8 is connected to the vertical current buffer circuit 7 to which the display enable signal is applied. A horizontal scanning type LED display device using a CRT control circuit, characterized in that the output terminals of the buffer circuits (5, 7) are connected to the LED mattress circuits (6), respectively. ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
