Difference 1: image clarity
Commercial displays have the function of intuitively reflecting the image quality. In addition to the full 19201080 resolution for the selection of display devices in the field of broadcast and television, liquid crystal displays are the preferred display, and the resolution of professional displays is automatically adjusted according to the display output (regardless of horizontal and vertical Can support); its high reliability and high-definition display capabilities will ensure that you can record and edit the high-definition audio and video, video signal complete display in front of the viewer. Ordinary display devices only support several common TV resolutions specified in the manual for effect processing, and special resolutions will cause screen blurring.
The second difference: LCD panel
Regardless of the TFT liquid crystal panels used in commercial and civilian displays, the differences between them are mainly manifested in the size of liquid crystal molecules, imaging processing and color, brightness and contrast, and viewing angles.
The liquid crystal molecules that make up an ordinary liquid crystal display panel are larger than those of a commercial display panel, because the viewing distance of a commercial display is generally not more than 1 meter. The most important thing is to show details, so the liquid crystal molecules that make up are smaller, of course. The cost of the panel is also more expensive. Ordinary liquid crystal displays are mainly used to represent the entire screen, and are not very demanding on small parts. More importantly, the use of large-molecule liquid crystals can reduce costs.
Difference 3: Stability
Commercial display products usually need to operate 24 hours a day to meet the needs of displaying various information, and the environment is much harsher than that of civilian display equipment, which places higher requirements on product performance.
Compared with ordinary display devices, in terms of design, the current, power consumption, temperature, and resistance to electrical interference, electrical shock, and margin of commercial displays, as well as the average barrier-free use time, are far greater than the former. At the same time, commercial displays must use a fully shielded metal shell to ensure electromagnetic compatibility and interference performance. In the selection of components, the components used in commercial displays have higher withstand voltage, current, temperature, humidity and other characteristics than TV sets. Components used.
In addition, the requirements for installation and debugging, especially the process requirements of components and the aging of the whole machine, are also higher. When ordinary display equipment is manufactured, the aging of the whole machine is usually about 8 hours when the assembly line is energized at room temperature, while the aging of the whole machine of the commercial display needs to be energized and aged for more than 24 hours on the aging streamline in a closed environment with high temperature and high humidity to ensure the whole machine The stability.
Difference four: interface
Because of connection requirements, commercial displays generally use industrial ports, such as RGB BNC color-difference interface with self-locking mechanism and professional DVI-D video interface. In addition, the commercial display can be controlled by S232 serial port, with more than 2,000 open control passwords, which can adapt to various industrial environments. When it is convenient to use multiple displays, all display devices can be controlled without the remote control, and it can assist various industrial requirements such as timing start-up, delayed start-up, and machine self-checking. Of course, many ordinary display devices are also equipped with RS-232 control ports, but its purpose is basically to control lights, etc., and cannot realize industrial control.
