The advantages and disadvantages of trade-off features and technical conditions are the first step in the display selection process, and the applications for displays in industrial equipment are different from those typically used for consumer products. The following seven basic factors should be considered when choosing.
First, the overall stability (including the use of time, anti-jamming, etc.)
Monitors often require 24 hours a day, 365 days of continuous power usage each day (and TVs typically only work a few hours per day) when they form a closed-circuit monitoring system, and some monitors may have a poor application environment. This requires monitors. The reliability and stability are higher. Compared with televisions, in terms of design, the display's current, power consumption, temperature and resistance to electrical interference, the ability and margin of electrical shock, and the average time between failures are much longer than those of TV sets. At the same time, the monitor must also use The shielded metal shell ensures electromagnetic compatibility and interference performance; in the selection of components, the characteristics of the components used in the display, such as voltage resistance, current, temperature, and humidity, are higher than the components used in the television; Debugging, especially the aging of the components and the entire process requirements, the display is also more demanding, TV manufacturing machine aging is usually on the assembly line at room temperature for about 8 hours, while the display of the whole machine aging requires high temperature The aging pipeline in a high-humidity, hermetically sealed environment is aged for more than 24 hours to ensure the stability of the whole machine.
Second, the image clarity
The liquid crystal display has the function of visually reflecting the image quality, and the full 1920*1080 resolution is used for the selection of display devices in the field of broadcast television. The liquid crystal display is the preferred display. The resolution of the professional display is automatically adjusted according to the display output (whether horizontally or horizontally. All can support); Its high reliability and high-definition display capability will ensure that you can record high-definition video and audio signals that have been edited and displayed in front of the viewer.
On the other hand, LCD TVs only support the common resolutions of several TVs specified in the description. Because there are only a few kinds of resolution of the civilian TV signal, the TV LCD will only take effect according to several common resolutions used by civil users. Special resolution will cause Huaping.
Third, the color reproduction
If the definition is mainly determined by the amplitude-frequency characteristics of the video channel, the degree of reduction is mainly determined by the phases of the chroma signals and the luminance signals of the three primary colors red (R), green (G), and blue (B) in the display. Decision. Since the monitor usually observes static images, the requirement for the color reproduction of the monitor is higher than that of the television. Therefore, the channel of the viewing channel of the professional monitor should have accurate compensation in the processing of luminance, chromaticity processing, and R, G, and B processing. Circuits and delay circuits to ensure phase synchronization of light/color signals and R, G, B signals.
On the other hand, LCD TVs are required to use the environment, and the images are displayed after touch-up processing. Can not truly reflect the actual effect.
Fourth, the use of machine materials
Due to the requirements of the use environment, the material of the casing of the LCD TV is made of metal. And the internal board lines are all industrialized designs that are not easy to age; the concept of energy saving and environmental protection is embodied: low energy consumption design; use of environmentally friendly materials. Regular appearance, convenient splicing, assembly and other industrial needs.
Conversely, the LCD TV enclosures are all non-metal materials. The internal board line is designed for civil use, and long-term power-on can easily cause mechanical aging. In addition, the appearance of civilian TVs is mostly irregular, with sound system, appearance arc system, etc. as auxiliary facilities for hearing and vision. The overall appearance and effect of construction will be greatly reduced.
Fifth, the port
The liquid crystal display uses industrial interface such as RGBBNC's chromatic aberration band self-locking mechanism interface and professional DVI-D video interface; conversely, LCD TV does not have BNC self-locking chromatic aberration input interface and DVI-D interface.
Six, control interface
LCD monitor can use S232 serial port control, open control password up to more than 200, adapt to various industrial environments. When it is convenient for multi-display use, all display devices can be controlled without using a remote controller, and various industrial requirements such as support, timing boot, delay boot, machine self-test and the like can be provided.
Conversely, LCD TVs can also use S232 serial control. However, only the control commands provided by the remote controller can be realized. It does not realize industrial control.
Seven, fanless architecture
The liquid crystal display is designed with no mechanical exhaust fan to keep the air circulation and heat dissipation, so as to avoid dust and fan noise problems caused by the mechanical exhaust fan. When the internal temperature rises due to unknown reasons, the display automatically controls the backlight system to keep the temperature at the highest level. Operating temperature.
On the other hand, LCD TVs have no strict requirements because of the application environment.
