본 고안은 모니터에 표시된 영상을 LED 표시 장치에 재현 하고자 할 경우 이를 인터폐이스(interface)할 수 있는 장치에 관한 것으로서 특히 모니터의근접한 수평 주사선을 합 또는 평균하여 한개의 수평 주사선을 만들어 LED 표시장치의 주사 선수와 일치시킬 수 있는 모니터의 수평 주사선수 변환 장치에 관한 것이다.The present invention relates to a device capable of interfacing an image displayed on a monitor to an LED display device. Especially, a single horizontal scan line is made by adding or averaging adjacent horizontal scan lines of the LED display device. A horizontal scanning player converting device capable of matching the scanning player of the present invention.
일반적으로 컴퓨터와 연결 사용하는 모니터는 많은 주사선에 의하여 문자 및 도형을 영상으로 표현되고 있으나 LED 표시 장치에 있어서는 크기와 부피, 전력 소모의 문제로 모니터의 주사선과 동일한 갯수의 주사선을 갖는 LED 표시 장치를 제작하기에는 많은 어려운 문제가 발생되며, 따라서 모니터에 나타나는 영상을 LED 표시장치에 재현 시키고자 할 경우에는 두장치 간의 주사선이 많은 차이가 있게 되어 원활한 영상 데이타 전송이 이루어지지 않게 됨으로서 LED 표시 장치에 영상으로 표현 시킬 수 없게 된다.In general, a monitor connected to a computer displays characters and figures as images by many scan lines. However, in the LED display device, due to size, volume, and power consumption, an LED display device having the same number of scan lines as the scan lines of a monitor is used. There are many difficult problems to produce. Therefore, if you want to reproduce the image displayed on the monitor on the LED display device, there are many differences in the scanning lines between the two devices. It cannot be expressed.
본 고안은 상기와 같은 점을 감안하여 모니터에 표현되는 영상을 LED 표시 장치에 그대로 재현시킬 수 있도록 하기 위한 인터페이스 회로를 구성하되 그 원리는 모니터의 주사선수와 LED 표시 장치의 주사선수를 일치시키기 위하여 모니터의 균일한 수평 주사선을 여러개 묶어 합 또는 평균하여 LED 표시장치의 주사선 1개에 해당되는 새로운 주사선을 만들어 모니터와 LED 표시 장치의 주사 선수를 일치시켜 영상 화면의 데이타전송이 이루어지도록 함으로서 모니터의 기능 향상에 기여하고자 하는데 본 고안의 목적이 있는 것이다.In consideration of the above, the present invention constitutes an interface circuit for reproducing the image displayed on the monitor as it is on the LED display device, but the principle is to match the scan player of the monitor with the scan player of the LED display device. The function of the monitor by tying or averaging several even horizontal scan lines of the monitor to create a new scan line corresponding to one scan line of the LED display device, and matching the scan player of the monitor and the LED display device to transmit data on the video screen. The purpose of the present invention is to contribute to the improvement.
이하 첨부된 도면에 의해 상세히 설명하면 다음과 같다.Hereinafter, described in detail by the accompanying drawings as follows.
제1도에서와 같이 모니터의 주사선을 LED 표시장치(3)의 주사선수와 일치시키기 위해 정수배로 나눈 LED표시장치 (3)의 1개 주사선에 해당되는 갯수만큼 (a개) 래치회로 (1ㅡ1ㅡn)를 a개 병렬로 연결하고 상기 각 래치회로(1ㅡ1ㅡn)에는 영상 데이타(DATA)가 인가되게 하며 이의 출력단을 가산기 (2)에 접속되도록 한주사선수 변환회로 (A)를 LED 표시장치 (3)의 주사선수와 일치되게 연설하는 한편 각 래치회로 (1ㅡ1ㅡn)에 인가되는 클럭(CLK)신호를 디바이더회로(4)에 의해로 분주한 클럭(CLK')신호와 가산기(2)의 출력을 LED 표시장치(3)에 연결하여서 된 모니터의 수평 주사선수 변화 장치인 것이다.As shown in FIG. 1, the number of latch circuits (a) corresponding to one scan line of the LED display device 3 divided by an integer multiple so as to match the scan line of the monitor with the scan player of the LED display device 3 1-n is connected in parallel, and each of the latch circuits 1- 1-n is supplied with image data DATA, and a single-scan bow conversion circuit (A) such that its output terminal is connected to the adder (2). The clock CLK signal applied to the latch circuits 1-1-n by the divider circuit 4 while speaking in a manner consistent with the scanning player of the LED display device 3. It is a horizontal scanning line change device of a monitor connected by connecting the clock signal CLK 'divided by the signal and the output of the adder 2 to the LED display device 3.
상기와 같은 구성으로 이루어진 본 고안의 작용 및 효과를 설명하면 다음과 같다.Referring to the operation and effects of the present invention made of the above configuration as follows.
먼저 모니터의 수평 주사선을 LED 표시장치(3)의 주사선수와 일치시키기 위해서 LED 표시장치(3)가 갖는 1개의 주사선에 해당되는 모니터의 근접한 수평 주사선을 합 또는 평균하여 나눈 후 (본 고안에서는 LED표시장치 1개의 주사선이 모니터의 a개 주사선에 해당한다고 가정함)정수(a)개 만큼 래치회로(1ㅡ1ㅡn)를 병렬로 연결시킨 상태에서 영상 데이타(DATA) 신호를 각 래치회로(1ㅡ1ㅡn)에 입력하면 클럭(CLK)신호에 의해 영상 데이타(DATA)가 각 래치회로(1ㅡ1ㅡn)에 동시 저장되기 시작하고 영상 데이타 저장이 완료되면 일시에 가산기(2)에 입력되어져 각 래치회로(1ㅡ1ㅡn)의 출력을 더하여 새로운 영상 데이타(DATA')를 갖는 하나의 주사선으로 되어 LED 표시 장치(3)의 1개 주사선에 인가됨으로서 모니터의 a개 주사선이 합해진 영상 데아타 (DATA)가 LED 표시장치(3)의 1개 주사선에 표현되어지며 이때 모니터 주사선을 정수(N)배로 나눈것과 강이 클럭(CLK)신호를 디바이더회로(4)에서도 정수배로 분주하여 LED표시장치(3)를 구동할수 있는 적절한 클럭(CLK)으로 변화시켜 새로이 형성된 영상 데이타 (DATA)를 쉬프트(shift)하게 된다.First, in order to match the horizontal scan line of the monitor with the scanning player of the LED display device 3, the adjacent horizontal scan line of the monitor corresponding to one scan line of the LED display device 3 is summed or averaged and divided (in the present invention, the LED Assume that one scan line of one display device corresponds to a scan line of the monitor) The image data (DATA) signal is connected to each latch circuit in a state in which the latch circuits (1-1-n) are connected in parallel by an integer number (a). When input to 1-1n, image data DATA starts to be simultaneously stored in each latch circuit 1-1n by the clock CLK signal. Is input to the output of each latch circuit (1-1-n) to form a single scan line having new image data DATA ', and is applied to one scan line of the LED display device 3 so that a scan line of the monitor Combined image data (DATA) LED display (3) 1 becomes expressed in lines at this time the monitor scan line the constant (N) times as divided river a clock (CLK) to an integral multiple in the divider circuit 4 to the signal The newly formed image data DATA is shifted by changing to an appropriate clock CLK capable of driving the LED display device 3.
따라서 이러한 주사선 변환회로 (A)를 LED 표시장장치(3)의 주사선수(n개)와 동일하게 연설하면 각 가산기(2)에서 출력되는 영상데이타(DATA)에 의해 모니터에 나타나는 영상이 LED 표시장치(3)에 표현되어질 수 있는 것이다.Therefore, if the scan line converting circuit (A) is addressed in the same manner as the scan players (n) of the LED display device 3, the image displayed on the monitor is displayed by the image data DATA output from each adder 2. It can be represented in the device (3).
이상에서 상술한 바와 같이 본 고안은 모니터와 LED 표시장치(3)의 주사선수를 일치시켜 모니터에 표현된 도형 및 문자 영상을 LED 표시장치 (3)에 재현시킬 수 있도록 하는 주사선를 변환할 수 있는 인터페이스회로를 제공함으로서 모니터의 신뢰성과 기능 향상에 기여할 수 있는 것이다.As described above, according to the present invention, an interface capable of converting scan lines to match the scan players of the monitor and the LED display device 3 to reproduce the graphic and text images expressed on the monitor on the LED display device 3 is possible. Providing a circuit can contribute to improving the reliability and function of the monitor.
