Selection elements of industrial touch display
Industrial touch displays are widely used in industrial control processes or equipment. The main difference between industrial displays and civilian or commercial displays is the shell design. Industrial touch displays generally use all-steel design. The panels are divided into ordinary iron, stainless iron, stainless steel, aluminum panels and other materials, which are dust-proof and shock-proof. With special design, industrial displays are mostly used in harsh environments such as high temperature, strong interference, and strong vibration. In this environment, ordinary commercial LCDs are difficult to work normally.
Industrial touch displays can be divided into embedded, rack-mounted, open, customized, flip-chip, etc. according to the installation method.
How to choose a suitable industrial control touch monitor? To purchase a suitable industrial monitor, you must choose from the aspects of space, viewing angle, readability, sustainability/dependability, etc.
The device design of the industrial touch display is more portable, so it can flexibly support the work that could only be done by expensive equipment under the same conditions. Industrial LCD monitors are currently produced in various series from 6.4 inches to 42 inches, and can provide industrial LCD monitor sizes suitable for use in various industries.
In a typical industrial environment, operators prefer to look at the display at an oblique angle rather than a positive angle. Therefore, it is very important that a picture is viewed from different angles (up, down, left, right, front, back) without any distortion or color change. Some techniques are used to improve the viewing effect of liquid crystal displays at oblique angles. The viewing angles achieved by some film-based technologies are usually 80° up, 60° down, 80° left and 80° right. These angles are sufficient for many applications, but some applications may require a larger viewing angle.
The readability of the display is another highlight of the industrial touch display. What is important is that displays in industrial applications need to support clear and precise visual effects from multiple angles in a strong light environment. Most industrial environments are environments surrounded by strong light, which poses a challenge to the readability of the display. The brighter the environment, the more difficult it is to transmit the touch display. One of the solutions to improve the readability of the display in a high-bright environment is to increase the contrast without increasing power consumption. The transflective technology provides benefits to the highlight industrial environment. A transflective display has both transmission and reflection characteristics. Just like it can be viewed in a dark environment through the backlight, and at the same time, the reflective performance is improved, so that it has excellent readability in a bright environment.
Sustainable and dependable
The ability to withstand temperature changes and vibration is an important consideration when choosing displays for contemporary industrial applications. The display must be flexible enough to prevent impacts or collisions by mechanical workers or peripheral equipment, and must be able to cope with various operating temperatures. Generally speaking, industrial touch displays are embedded in airtight containers and are part of large equipment. In these cases, the temperature is affected by the heat generated by the closed container and surrounding equipment. Therefore, keeping in mind the actual storage and operating temperature requirements is very important when choosing a monitor. Although some measures have been taken to dissipate the heat generated, such as using fans in airtight containers, choosing a monitor that is most suitable for these environments is the most effective way to ensure compliance with storage and operating temperature requirements. The improvement of liquid crystal materials also makes it possible to expand the optimal temperature range of liquid crystal displays.
