Industrial control touch displays are displays that are used in industrial control processes or equipment. The main difference between industrial display and civilian or commercial display is that the outer casing design is generally all-steel design. The panel is divided into different materials such as ordinary iron plate, stainless steel, stainless steel and aluminum panel. It is specially designed for dustproof and shockproof. It adopts industrial grade. LCD screens, in the case of high environmental requirements, consider the use of a wide temperature LCD screen, currently only a few foreign large manufacturers to produce such displays, the price is more expensive. Industrial liquid crystal displays are often used in harsh environments such as high temperature, strong interference, and strong vibration. In this environment, ordinary commercial liquid crystal displays are difficult to work properly.
Industrial liquid crystal displays can be divided into: embedded, rack-mounted, open, custom, flip-chip, etc. according to the installation method. Choose a suitable display for industrial use, from space, perspective, readability, sustainability / dependability.
1, space
The design of the liquid crystal display device is more portable, so it can flexibly support the work that can be done by the valuable equipment under the same conditions. Industrial liquid crystal displays are currently available in 6.4-inch to 42-inch series and are available in industrial LCD displays for use in a variety of industries.
2, perspective
In a typical industrial environment, operators are more willing to look at the display at an oblique angle rather than a positive angle. Therefore, it is important that a picture is viewed from different angles (up, down, left, and right) without or with little distortion or color change of the picture. Some techniques have been used to improve the viewing of liquid crystal displays on bevels. Some film-based techniques typically achieve viewing angles of 80°, 60°, 80° left, and 80° right. These angles are sufficient for many applications, but some applications may require a larger perspective. Nanjing Yanwei’s industrial LCD monitors can be customized for customers with full-view (85°) industrial LCD monitors for various industries.
3, readability
The readability of the display is another highlight of the LCD display. Importantly, displays in industrial applications need to support clear and precise visuals from multiple angles in a strong light environment. Most industrial environments are an environment surrounded by glare, which poses a challenge to the readability of the display. The brighter the environment, the more difficult it is to transmit the liquid crystal display. One of the solutions to improve the readability of the display in a high-light environment is to increase the contrast without increasing power consumption. Transflective technology offers benefits in a highly industrial environment. A transflective display features both transmission and reflection. Just as it can be viewed in a dark environment by backlighting, it also provides reflection performance, making it extremely readable in high-light environments. The industrial display provided by Nanjing Research and Development Co., Ltd. can provide the brightness required for industrial liquid crystal displays suitable for various industries.
4. Sustainability / Dependence
The ability to withstand temperature changes and vibrations is an important consideration in selecting displays for contemporary industrial applications. The display must be flexible enough to prevent impact or impact from mechanical or peripheral equipment and must be able to handle various operating temperatures. In general, the display is embedded in a closed container and is part of a large piece of equipment. In these cases, the temperature is affected by the heat generated by the closed container and the peripheral equipment. Therefore, keeping in mind the requirements for actual storage and operating temperature is very important when choosing a display. Although some measures have been taken to dissipate the heat generated, for example, using a fan in a closed container, choosing the display that best fits these environments is the most effective way to ensure that storage and operating temperature requirements are met. Improvements in liquid crystal materials have also made it possible to expand the optimum temperature range of liquid crystal displays.
