INDUSTRIAL LCD: Engineered For Extreme Conditions

Generally, industrial monitors consist of two basic types – the cathode ray tube (CRT) and the flat panel displays (FPD).

CRT monitors consist of sealed glass tubes generating light from an electron beam, while FPD monitors are thin and flat monitors and are often used for notebook computers.

FPD monitors, on the other hand, have 3 main types – the liquid crystal display (LCD), the plasma display, and the electroluminescent display (ELD).

As a flat panel display, industrial LCD monitors use two sheets of polarizing material with a liquid crystal solution in between. Plasma displays, in the mean time, use gas to fill up the gap between two glass sheets that are lined up in parallel, while ELDs use a thin film of phosphorescent substance sandwiched between two plates.

There are four mounting types for industrial monitors – panel mount, wall mount, rack mount, and chassis mount. Industrial displays basically differ in mounting style and external connections.

Screen size, image, resolution and dot/pixel pitch are some of the most common specifications for industrial monitors.

Compared with plasma and ELDs, industrial LCD - type monitors are more commonly used since they are more durable and do not overheat as easily.

It is a well known-fact that once something is made for industrial use, durability ensues. Industrial LCD products are no different and durability is probably one of the main differences between ordinary LCD monitors and industrial ones. Another factor unique to industrial LCD products is that they are designed to maximize a company’s productivity.

Industrial LCD products are designed and built to withstand harsh environment and extreme operational conditions usually encountered in industrial and commercial set-ups. They are intrinsically safe and are often explosion-protected.

Industrial LCD products are also engineered to resist shock and vibration, as well as electromagnetic forces and extreme temperature.

Normally used as operator interface display, industrial LCD monitors withstand water and are dust-proof. They are also expected to perform well beyond ordinary industrial monitors.
