How Should a Procurement Officer Select the Right Industrial Display Monitor?

Industrial display monitors are displays used in industrial settings. Unlike normal commercial and household environments, industrial environments are often characterized by more dust, electromagnetic interference, vibrations, etc.

If an ordinary smart industrial display monitor is used in an industrial setting, its lifespan will be significantly shortened, and it may frequently malfunction before the warranty period expires. As one professional industrial panel PC touch screen manufacturers that demand high equipment stability, this is absolutely intolerable. Therefore, there is a need for a smart industrial display monitor with excellent sealing performance, good dust-proof effects, the ability to shield signal interference, ensuring it is not disturbed by other devices nor disturbs the operation of other devices, with good vibration resistance, some level of waterproofing, ultra-long standby time, compatibility with multiple touch technologies, high-brightness display, high-resolution display, and suitability for high/low-temperature environments. For purchasers, selecting an appropriate industrial display monitor is not an easy task; many factors need to be considered to ensure it meets production demands.

Core Performance of Industrial Display Monitors

Industrial display monitors are significantly different from household or commercial monitors; they need to operate stably in complex and harsh industrial environments for a long time. The first consideration is contrast ratio. Unlike consumer monitors primarily used for direct viewing, industrial-grade monitors might not be viewed from the optimal distance or under ideal lighting conditions, so monitors with higher contrast ratios are the best choice. For 9.7-inch, 10.4 inch industrial display monitor, or 12.1-inch monitors used in most industrial fields, a contrast ratio of 450:1 is ideal.

Since most flat-panel displays are used indoors, the brightness is around 250-300 cd/m2 (nits), and 15-inch diagonal LCDs are the most common. However, this brightness level is insufficient for industrial environments, where ambient light is stronger and can easily exceed the brightness of the LCD backlight. Moreover, touch screens are frequently used in industrial environments, which can reduce the monitor’s brightness and make it appear dim. The required brightness for common applications such as medical, industrial, and public kiosks should be at least 450 cd/m2. In the past, response time for passive display technologies, including LCDs, was extremely poor compared to active emissive display technologies.

Environmental Adaptability of Industrial Display Monitors

Like many technologies, there are changes in design within global flat-panel LCD products. In industrial-grade panels, such changes might occur every five years or longer. These changes arise from the need to adapt to technological advancements or better designs. Thus, maintaining certain levels of continuity when designing industrial and medical equipment is very important. This includes having the same mounting holes, connector positions, and even some identical display sizes. When a display changes within five years, the end product can still have a 10-year lifecycle.

Test reports for industrial display monitors will indicate relevant environmental adaptability tests. Vibration tests simulate the various vibration environments a product might encounter during transportation, installation, and usage to determine its ability to withstand these environments. This helps to assess the component, part, and whole machine’s resistance in the expected transportation and usage environments. Low-temperature and high-temperature operational tests fully examine the equipment’s suitability under such conditions.

As technology continuously advances, the software for industrial display monitors must also be constantly updated and upgraded. Purchasers should select industrial display monitor suppliers that offer good software support and upgrade services to ensure the equipment remains in optimal condition.
