What Are the Features of Industrial Displays?

What Is an Industrial Display

Industrial display refers to equipment used in industries, which is quite different from ordinary displays. The structure and materials of an industrial display usually employ aluminum alloy, providing good heat dissipation performance. Industrial displays have high environmental requirements. The display not only needs to adapt to various industrial environments but also needs to maintain stable operation.

Features of Industrial Displays

Comparison with consumer displays

Unlike consumer displays mainly used for direct viewing, the user may not be watching an industrial display from the optimal distance or under ideal lighting conditions. Therefore, a higher contrast industrial display is the best choice. For most industrial fields, a 10.4-inch, 12.1-inch, or 15-inch display with a contrast ratio of 450:1 is ideal.

Color

In some industrial applications, specific color information is more important than text or numbers. Measuring the percent of NTSC color saturation is crucial for comparison. In an industrial display, color saturation completely depends on the influence of the backlight. CCF backlight is a very popular technology and can achieve 70% or 80% NTSC color saturation.

Viewing angle

Commercial consumer displays are usually designed for single-user direct viewing from the front, which is very rare in most industrial applications. For large machinery, it is almost impossible to operate directly in front of the display, especially when there are multiple displays facing viewers at different angles. Displays should have a wide viewing angle or be considered 'glance-able'. Consumer industrial displays generally cannot meet such requirements due to their use of twisted nematic technology, thus limiting the viewing angle. Therefore, a wide viewing angle is required to better accommodate industrial applications.

Mechanical performance

Like many technologies, global flat-panel LCD products also undergo design changes. In industrial-grade panels, such changes may occur every five years or even longer due to technical advancements or better designs. Therefore, maintaining a certain level of continuity in industrial and medical equipment design is essential. This includes the same mounting holes, connector locations, and even some consistent industrial computer display sizes. When changes occur within five years, the terminal product can have a lifecycle of 10 years. Considering these standard specifications and the company's design strategy before choosing a display is beneficial. In contrast, consumer displays can change every 6 months, making them difficult to use in configuration-controlled applications.

Service life

For consumers in the industrial market, whether used in kiosks or display terminals on oil rigs, it is rare to find displays guaranteed to work for 10 years. Manufacturers can provide industrial computer displays with a lifespan meeting or exceeding 10 years, but most industrial-grade display manufacturers will at least produce them for 3 years, and in practice, the supply period can last at least 5 years.

Vibration damping

In many terminal products such as handheld or portable devices, vibration testing is usually required to ensure the device can be used in commercial or emergency response vehicles. Vibration damping is very important in these applications as it allows the designer to have some leeway when designing the final product.
