Commercial and consumer monitors are typically designed for single use directly in front of the monitors. In most industrial monitors applications, this situation is very rare. For example, a physician or nurse cannot stop and watch the monitor directly during the treatment. They just want to know the expected data. For large machines, it is simply impossible to operate directly in front of the monitors. For navigation of a ship or aircraft, it is inconvenient for the driver to sit directly in front of the LCD. Especially when there are multiple monitors, they face the viewer at different angles.
Industrial monitors should have a wide viewing angle or be considered as "a glance at what you see". Consumer displays generally do not meet this requirement because they use Twisted Nematic, so viewing angles are limited. In order to better adapt to industrial applications, industrial monitors are required to have a wide viewing angle, and monitors technologies (such as ASV or MVA) with a viewing angle of up to 178°have been developed.
