In general, it refers to a display monitor, and some dual-display graphics card can output and the other is called a monitor. Monitor the development of experienced black and white to color, from blinking to not blinking, and then the development of BSV LCD technology from CRT (cathode ray tube) to the LCD (liquid crystal). Monitor as an important application products, various types of monitors endless, liquid crystal (LCD), plasma (PDP), a light emitting diode (LED) and so on advanced technology monitors products have been widely used. As CCTV monitors display terminal, it is in addition to the camera outside monitoring system an integral part. For a long time the monitor is mainly used in finance, jewelry stores, hospitals, subways, railway stations, airports, exhibition of the commercial office, leisure * places, etc., responsible for the security aspects. The development of technology, closed-circuit monitoring system has been very good the whole cost of adjustment. More and more small businesses have affordability, began to establish their own monitoring system to achieve security or other monitoring needs. Divided by size: LCD monitors are divided into 8/10/12/15/17/19/20/22/24/26/32/37/40/42/46/47/52/57/65/70/82 / 108 inch monitors. Divided by color: color, black and white monitor. Press Scan points: interlaced and progressive scan. By type: Full aluminum LED monitors, LCD monitors, rear projection, CRT monitors, plasma monitors. The screen points: flat, general screen, spherical and the like. Material: CRT, LED, DLP, LCD and so on. According to zoning: security monitor, monitor monitors, radio and television monitors, industrial monitors, computer monitors. TV monitor in function than simple but in performance, but more demanding than television requirements, the main difference is reflected in the three "degrees." Since the traditional TV image clarity is received television RF signals emitted, the image signal corresponding to the video bandwidth is typically less than 6M, and thus the clarity of television lines typically greater than 400, requires a monitor with high image clarity degree, it is the professional monitor on channel circuit compared to traditional TV in terms of compensation and should have the bandwidth boost circuit, so that the pass band wider, higher image sharpness. If the color reproduction of clarity is mainly composed of video channel amplitude-frequency characteristics of the decision, the reduction degree mainly by the monitor in red (R), green (G), and blue (B) three primary color signal and luminance phase signal of the decision. Since the monitor is usually observed as a static image, and thus to monitor color reproduction of the requirements higher than the TV, put it as the professional channel monitors in brightness, color processing and R, G, B treatment should have Exact compensation circuit and a delay circuit to ensure that the light / color signal and R, G, B signal phase synchronization. Color LCD monitor has been a matter of concern, many manufacturers have made 16.2M and 16.7M these two criteria, these two standards can intuitively reflect the color reproduction capabilities of the LCD monitor. If the color of the LCD monitor more stringent requirements, it is the best option with the product 16.7M in. Bobang Cheng Technology Co., Ltd.
