What is an Industrial LCD Monitor?

Industrial LCD is a liquid crystal display used in industry. It has various display sizes and installation methods. Unlike ordinary LCD monitors, it can adapt to extreme environments, stable operation and long service life.

According to the installation method, it can be divided into: embedded, shelf-mounted, open.

Industrial LCD monitor space size

The issue of space is a significant factor that designers in the industrial field need to consider. Industrial LCD monitors currently have a series of manufacturers from 6.4 inches to 70 inches.

Industrial LCD display visibility

Good visibility is a highlight of industrial LCD displays. Displays in industrial applications need to support clear and precise visual effects from multiple angles in a strong light environment. Most industrial environments are surrounded by strong light, which poses a challenge to display visibility.

The brighter the environment, the more difficult the LCD transmission is, because people's standard readable brightness is 250 ~ 300cd / . Some LCD manufacturers are trying to expand the range to more than 450cd / . But these displays require more energy and this is not the best solution. Furthermore, these brightness levels are not sufficient to function in very bright environments.

At present, many domestic manufacturers have highlighted LCDs to achieve more than 1800cd / , including Baoyi Technology, many military LCDs are above 2000cd / .

In a typical industrial environment, operators prefer to see 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, front and back) without or little distortion or color change in the picture. Especially the display settings on consumer applications can't do the job well, because the picture may be missing or cannot be seen obliquely.

Some techniques are used to improve the viewing effect of LCDs at oblique angles. Some film-based technologies typically achieve a viewing angle of 80 ° above, 60 ° below, 80 ° left, and 80 ° right. These angles are sufficient for many applications, but some applications may require a larger perspective.

Coplanar conversion technology (IPS), multi-quadrant vertical alignment technology (MVA), and ultra-precision thin film transistor technology (SFT) provide a popular choice for various LCD manufacturers. These patented technologies enable greater viewing angles than in the field of film technology.

For example, NECLCD technology's SFT technology achieves 85 for up, down and left. The angle of view allows the machine operator to view the LCD from almost any angle without major image distortion or color changes.

Industrial LCD display resolution

Size and resolution also play a role in overall readability. In general, 6.5, 8.4, 10.4, 12.1, and 15-inch LCDs in LCD mode are mostly used in industrial applications. These sizes provide enough space for views, signal waveforms, or other graphic data without taking up too much space on the device.

The requirement for resolution is mainly determined by the display information or display data. In the past, VGA, SVGA, and XGA resolutions were the most popular.

However, more and more manufacturers are paying attention to the profits of large aspect ratio displays, such as WVGA and WXGA. Large aspect mode allows users to view longer information waveforms and more data on one display. These displays can also be designed to incorporate touch key functions on the display surface, allowing users to view data on large aspect displays or switch between standard aspect ratio displays that incorporate touch screen capabilities. This added advanced functionality is extremely helpful in simplifying the user interface.

Industrial LCD Monitor Sustainability

The ability to resist temperature changes and vibrations is an important consideration when choosing a display for contemporary industrial applications. The display must be flexible enough to prevent a mechanical operator or a peripheral device from being bumped or bumped, and it must be able to handle various operating temperatures. Compared with CRT, LCD is more resistant to temperature changes, impact and vibration.

Storage and operating temperature are also the main variables in selecting industrial equipment displays. Generally, the display is embedded in a closed container and is part of a larger piece of equipment. In these cases, the temperature is affected by the heat generated by the closed container and surrounding equipment.

Therefore, keeping in mind the requirements of actual storage and operating temperature is very important when choosing a display. Although some measures have been taken to dissipate the heat generated, such as using a fan in a closed container, choosing a display that is best suited 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 LCDs. At present, many LCDs have achieved a temperature range of -10 to 70 ° C.

Industrial LCD monitor availability

When choosing to manufacture a display in a production environment, some other features that are more invisible than others need to be considered. For example, it is critical to ensure that downtime is minimized. In order to achieve maximum utilization, it is important to choose the highest quality monitor possible and have spare parts available for on-site repairs rather than external repairs.

Industrial application displays also require a long-life product life cycle. When manufacturers no longer make a certain model, the new display should be backwards compatible with existing closed containers without requiring the entire system to be redesigned.
