The difference between monitor and TV 2: color reproduction <br> If the definition is mainly determined by the amplitude-frequency characteristics of the video channel, the degree of reduction is mainly caused by red (R), green (G), The blue (B) three primary colors are determined by the chrominance signal and the phase of the luminance signal. Since the monitor usually observes a static image, the color reproduction degree of the monitor is higher than that of the TV. Therefore, the viewing channel of the professional monitor should have the brightness, chromaticity processing, and R, G, and B processing. Precise compensation circuit and delay circuit to ensure the phase synchronization of the bright/color signal and the R, G, and B signals.
The difference between monitor and TV is three: the stability of the whole machine <br> When the monitor constitutes a closed-circuit monitoring system, it usually needs 24 hours a day, 365 days a year for continuous uninterrupted power-on (the TV usually only works for a few hours a day) ), and the application environment of some monitors may be harsh, which requires the reliability and stability of the monitor to be higher. Compared with TV sets, the monitor's current, power consumption, temperature and resistance to electrical interference, electric shock capability and margin, and average trouble-free operation time are much larger than TV sets, and monitors must also The use of a fully shielded metal casing ensures electromagnetic compatibility and interference performance; in the selection of components, the components used in the monitor have higher voltage, current, temperature, humidity and other characteristics than the components used in the TV; In the installation, debugging, especially the process requirements of components and aging, the requirements of the monitor are also higher. When the TV is manufactured, the aging of the whole machine is usually about 8 hours at room temperature on the assembly line, and the whole machine of the monitor For aging, it is necessary to electrify and aging for more than 24 hours in the aging line of high temperature and high humidity sealed environment to ensure the stability of the whole machine.
If a television is used as the terminal monitor of the monitoring system, the components used in the television are not suitable for uninterrupted continuous use, except that the image may be blurred (lower definition and poor color reproduction). If you force the use of a TV as a monitor. Light is prone to malfunctions, and in severe cases, accidents may occur due to excessive operating temperature of the TV.
