Availability of industrial LIQUID crystal displays
January 9, 2017
When selecting a display for manufacturing in a production environment, there are other, more invisible features to consider. For example, you must ensure that downtime is kept to a minimum. To achieve maximum utilization, it is very important to select the highest quality display and have spare parts available for on-site repairs rather than sending them out for repairs.
Displays for industrial applications also require long product life cycles. When a manufacturer no longer produces a certain type of display, the new display should be backward compatible to fit existing sealed containers without requiring a redesign of the entire system.
The ability to withstand temperature changes and vibration is an important consideration when selecting displays for modern industrial applications. The display must be flexible enough to prevent shocks or collisions by mechanical operators or peripherals, and must be able to cope with a variety of operating temperatures. Compared with CRT, LCD is more resistant to temperature change, shock and vibration.
Storage and operating temperatures are also major variables in selecting industrial equipment displays. Typically, displays are embedded in a closed container and are an integral part of a larger device. In these cases, the temperature is affected by the heat generated by the closed container and the surrounding equipment.
Therefore, it is important to keep in mind the actual storage and operating temperature requirements when selecting a display. While some measures have been taken to dissipate the generated heat, such as using fans in sealed containers, choosing a display that is best suited to 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. Many LCD displays have temperatures ranging from -10 to 70°C.
