1, shell

The shell design of industrial liquid crystal generally adopts all-steel design, and the panel is divided into ordinary iron plate, stainless steel, stainless steel, aluminum panel and other different materials, which are dustproof and shockproof.

Generally, the shell material of ordinary display adopts plastic shell, but the plastic shell has weak radiation suppression, weak anti-interference ability and unstable signal, which will be interrupted.

2. Temperature

Adopt industrial LCD screen. In the case of high environmental requirements, consider a wide temperature (-40 to 85 degrees) LCD screen.

Step 3 compare

For industrial displays, users may not watch at the best distance or under ideal lighting conditions, so a display with higher contrast is the best choice. For 10.4 inch, 12. 1 inch or 15 inch monitors used in most industrial fields, the contrast ratio of 450: 1 is the best.

Step 4 be smart

Because most common displays are used in indoor environment, the brightness is about 250 ~ 300 CD/m2 (nits), and the LCD with diagonal size of 15 inch is the most commonly used. However, the display of this brightness level can not meet the requirements in industrial environment, because the ambient light is stronger, and its brightness easily exceeds the brightness of LCD backlight.

Moreover, the touch screen is often used in industrial environment, which will also reduce the brightness of the display screen and make it look darker. In ordinary medical, industrial and public telephone booths, the required brightness should reach at least 450 cd/m2. Response time In the past, the response time of passive display technology including LCD was very poor compared with that of active light-emitting display technology.

Extended data

Classification of industrial monitors:

The installation methods of industrial LCD can be divided into rack, flip-chip, embedded, open and modular.

Overhead industrial monitors are used in industrial control cabinets, cabinets and other equipment. Cases are generally in U, and 1U is equivalent to 44CM. Commonly used 4U, 6U, 8U, etc.

The flip-chip industrial display is inverted from the back of the cabinet, and only the LCD area is displayed on the front of the cabinet.

Embedded industrial display is directly embedded from the front of the cabinet and fixed on the side with hooks.
