In a broad sense, monitors and monitors are all practical devices. They all use technical processing to convert electronic signals into images and display them on the screen. Generally, we can collectively refer to televisions, VCDs, and DVDs. For monitors or monitors. In fact, everyday life is done. The reason why we have to distinguish between these two concepts is that we use the display screen of the civilian-class desktop display device from the narrow sense, and use the industrial-grade display device specifically used for security monitoring as the monitor.
Their main difference is:
The use of different materials: Computer monitors and monitors have a completely different meaning for video rates. The monitor uses "short afterglow tubes" and the monitor uses "middle afterglow tubes". There is a fundamental difference in the recognition ability. Usually the display has a smaller dot pitch or a higher vertical refresh rate, but the "short residual tube" adopted by the display has only the ability to recognize the color equivalent to the "afterglow tube" in the monitor. 1/5 or so). A high-end monitor using only its own phosphor is enough to sell several high-end displays. The monitor itself is mainly used for "still images". It is mainly used to display the coordinates of images and texts and special application environments. (Strictly speaking, monitors are not good at expressing moving images (please note the images and the images in the real sense). the difference)). The monitor is designed specifically for motion pictures. It does not emphasize concepts such as the dot pitch or vertical refresh rate of the monitor, but rather emphasizes the ability to identify and recognize colors (requiring absolute neutrality of the image, natural, Accurate, broadcast-quality CTMs do not allow slight distortion and color cast on images and colors.
The input signal is different: the color monitor inputs the AV analog video signal, and the computer monitor inputs RGB three-color VGA digital signals.
Different resolution: Normal color monitor is generally 420 lines or 480 lines and the computer monitor is 800*600 resolution.
Different levels of radiation: Some color monitors do not have radiation treatment (some manufacturers in order to make the image more clear, increase the line deflection voltage, resulting in electrostatic radiation), and computer monitors must have radiation detection certification, or the use of liquid crystal displays simply do not radiation.
Refresh frequency is different: normal color monitor refresh frequency should be below 50Hz (simulation), the average computer monitor easily to 75hz.
Anti-jamming capability is different: monitors in the design of current, power consumption, temperature and electrical interference, electrical shock and redundancy and average failure-free use time are much greater than the display. At the same time the monitor must also use a fully shielded metal enclosure to ensure electromagnetic compatibility and interference performance.
Different ways of signal restoration: When the camera shoots, the light signal is converted into RGB electrical signals. Through the matrix circuit part in the middle of the camera, the RGB initially converted electrical signals are converted into Y/RY/BY signals. The process of monitor display is just the opposite process of converting the matrix to the corresponding matrix circuit and the matrix circuit of the camera, so that the original image signal can not be faithfully reproduced and presented. The VGA input mode of the monitor does not specifically consider the image restoration problem of the camera, and is not as good as the monitor in the degree of reduction.

What is the LCD splicing screen The LCD splicing screen is made up of a plurality of splicing units for liquid crystal splicing, which can be used alone as a display and can be spliced ​​into a large screen. According to different use requirements, to achieve large and small variable variable large screen function: single-screen split display, single-screen single display, any combination of display, full-screen LCD splicing, dual splicing LCD screen, vertical screen display, image border Optional compensation or cover, support for digital signal roaming, zoom stretching, multi-screen display, setting and operation of various display scenarios, full HD signal processing in real time.
