Emperor Aidi Technology Analysis: With the progress of LCD splicing technology, the input and output interfaces of LCD splicing screen are more and more abundant. For example, ADI's LCD splicing screen products provide VGA, HDMI, color difference components, hybrid video, USB, and RF TV signals. The interface can be quickly and easily connected with various devices; in many engineering projects, users are very concerned about the display signal, which affects the direct use of the large-screen LCD system; then the Emperor Ai Di will analyze the signal on the LCD large-screen system for you. knowledge.
Generally, the display signals of the large-screen splicing area are divided into three categories: video, computer, and network; currently, the LCD splicing screen is mainly based on video images and computer screens. The following is the display signal analysis of the LCD splicing system:
Video interface generally provides: RCA composite audio and video input group, YCbCr color difference analog input group; industrial interface using BNC card. Cable specifications are commonly used 75-3,75-5,75-9 three, the general indoor use 75-3: transmission distance control within 100 meters; 75-5: transmission distance within 100 meters - 300 meters, professional cable : 400-800 meters; 75-9: The transmission distance is 300 meters - 300 meters; 800 meters, professional cable: 800-1600 meters; 800 meters - 20 kilometers, with fiber optics. More than 20 kilometers, fiber + network.
Computer interface generally provides: VGA analog computer input all the way; D-Sub 15-pin and RGBHV two main specifications, wire diameter is generally 75-2,75-3,75-5 three. The VGA transmission distance is 75-2 lines, 20 meters-30 meters, 75-3 lines, 30 meters-50 meters, and 75-5 lines 50 meters-100 meters.
The digital computer interface generally provides: DVI digital video or HDMI digital audio and video input all the way; commonly used specifications are 1.8 meters to 15 meters.
