Industrial LCD monitors and the difference between an ordinary LCD TV

Weigh the advantages and disadvantages of features and technical conditions is the first step in the display selection process, and, for industrial applications and display equipment for consumer products are usually different. Should be considered in the choice of the following seven basic factors. 1, the whole stability (including the use of time, and interference) Monitor closed circuit monitoring system in the form, usually 24 hours a day, 365 days a year using a continuous uninterrupted power (and the TV is usually only work a few hours a day), and some display environments may be more difficult, which requires higher reliability and stability of the display. Compared with the TV, in the design, display of current, power, temperature, and anti-radio interference, electrical shocks and failure-free margin and the average use of time are much larger than the TV, but also must use the full display Shielded metal enclosure to ensure electromagnetic compatibility and interference performance; in the selection of components, monitors the use of components of the pressure, current, temperature, humidity and other characteristics of various components used to be higher than TV; in installation , commissioning and machine components, especially the aging process requirements, the display requirements are higher, making the TV when the machine is usually in the aging temperature on the power line about 8 hours, and the display of the machine you need high-temperature aging , closed environment, high humidity aging aging power lines on more than 24 hours, to ensure overall stability. Second, the image sharpness LCD display with intuitive features reflect the image quality, coupled with the full 1920 * 1080 resolution display for the field of radio and television equipment used, is the preferred LCD display, professional display shows the output resolution is automatically adjusted according to the resolution (no matter if they had can support); its high reliability and high-definition display capabilities will ensure that you can record high-definition video edited, the video signal displayed on the full front of the viewer. Conversely, LCD TVs only support manual provides several popular TV resolution. Because the resolution of civil TV signals only a few, according to civilian users as long as LCD module with resolution of the effects of several commonly used treatment, a special resolution will result in the video. Third, the color reproduction If the resolution is mainly by the video channel of the amplitude-frequency characteristics of the decision, mainly by the reduction degree display red (R), green (G), blue (B) Three-color chrominance signal and luminance signal of the phase of the a decision. Because the display is usually observed as a static image, and thus the requirements of the display color reproduction higher than the TV, so as to put channel professional monitors in brightness, color processing and R, G, B should have an accurate handle on compensation circuit and delay circuit to ensure that the light / color signal and the R, G, B signals of phase synchronization. Conversely, LCD TV with environmental requirements as actions, and the image is processed for display through the polish. Can not truly reflect the actual results. Fourth, the use of materials, machine As the usage environment, LCD TV part of the machine casing material metal texture. And the internal plate line are industrial design, not easy to aging; embodiment of energy saving ideas: low-power design; environmentally friendly materials to use. Neat appearance, ease of splicing, installation and other industrial needs combined. Conversely, LCD TV sets all of the non-metallic casing materials and design. Internal board line is designed for civilian use, aging parts likely to cause long boot. Other rules of civil non-appearance of many TV appearance, with sound system, the appearance of the arc as the auditory and visual systems, ancillary facilities, the construction of up overall appearance and effectiveness will be greatly reduced. Fifth, the port LCD monitors use more industrial port such RGBBNC the color interface with self-locking institutions and professional DVI-D video interface; Sixth, control interface LCD monitors can be used S232 serial control, password control and open up more than 200, to adapt to a variety of industrial environments. Easy to use multiple monitors, not by remote control can control all display devices, and can assist, regular boot, delay start, the machine self and other industrial requirements. Conversely, LCD TV also can be used S232 serial control. But only to achieve remote control commands are available. Industrial control and can not be achieved. Seven, fanless architecture LCD monitor is designed with no mechanical exhaust fan to maintain air circulation and cooling, thereby avoiding mechanical exhaust fan caused by dust and the fan noise, when the internal temperature due to unknown reasons, increases the monitor automatically control backlight system temperature is kept at the highest temperature below. Conversely, LCD TV due to the environment due to the application, which is not critical. |
