Perspective of industrial displays

Commercial and consumer displays are typically designed for single person use sitting directly in front of the monitor. In most industrial applications, this situation is very rare, for example, physicians or nurses cannot stop and directly watch the monitor during the diagnosis and treatment process, they just want to know the expected data. For large machines, it is simply impossible to operate them directly in front of a monitor. For navigation of ships or aircraft, it is also inconvenient for the pilot to sit directly in front of the LCD, especially when there are multiple displays facing the viewer from different angles.
The monitor should have a wide viewing angle, or be considered to be able to understand the displayed content at a glance. Consumer displays generally cannot meet such requirements because they use Twisted Nematic technology, which limits the viewing angle. In order to better adapt to industrial applications, displays are required to have a wide viewing angle. Display technologies with a viewing angle of up to 178 °, such as ASV or MVA, have been developed.
