What are the advantages of industrial displays?
An industrial display is a display for the application of industrial control processes or equipment. What’s unique about it? Dustproof and shock-proof special design with industrial grade LCD display. In the case of higher than required, consider a wide temperature LCD display. Currently, only a handful of large foreign factories produce such displays at higher prices. The protection level of industrial displays is indicated by IP*, the former is dustproof and the latter is waterproof. The highest dustproof rating is 6, and the highest waterproof rating is 8.
Step 1: Brightness
Since most flat panel displays are used in the chamber environment, the brightness is about 250-300 dm2(nits), the most commonly used diagonal size of 15 inch LCD displays. However, in industrial environments, displays of this brightness level are used and cannot meet the requirements because the ambient light will be stronger and its brightness will easily exceed the brightness of the LCD backlight. In addition, the use of touch screens is often used in industrial environments, which can also reduce the brightness of the display and make it appear darker. In ordinary medical, industrial and public telephone booths, the required brightness should be at least 450cd/m2. In the past, passive display technologies, including liquid crystal displays, had very poor response times compared to active light-emitting display technologies. Whether it’s a laptop or a desktop, in a consumer display, a time response of less than 30 milliseconds is sufficient. However, in the industrial, medical and gaming sectors, users can feel the movement of the dynamic content environment, which means that the LCD should be required to respond more quickly with time. Among the relatively new technologies, AVS(Advanced Super View) technology or MVA(Multivariable vertical alignment) technology have enabled response times of less than 10ms. In ASV TVS, the index can reach 6 milliseconds.
Step 2 Compare
Unlike consumer display doctors, which are primarily used for direct observation, users may not be able to view industrial-grade displays at optimal distances or under ideal lighting conditions, so a higher-contrast display doctor is the best choice. For 10.4 “, 12.1 “or 15” displays used in most industrial sectors, 4501 contrast ratio is the best choice.
Step 3: Color
In some industrial applications, where special color information is more important than text or numbers, the percentage of NTSC color saturation measured by color is very important. In liquid crystal display products, color saturation depends entirely on the effect of the backlight. CCF backlighting is a very popular technique that can achieve 70% and 80% NTSC color saturation. In some applications, this range is not competitive enough, and sometimes the range to be achieved is close to 100% of the NTSC color saturation. This full color saturation is usually achieved in liquid crystal display products that use light-emitting diode backlighting.
4. Perspective
Commercial and consumer displays are usually designed for use by individuals sitting directly in front of the display. However, in most industrial applications, such cases are very rare, for example, physicians or nurses cannot stop during diagnosis and treatment to directly observe the display, and they only want to know the expected data. For large machines, the operation just shows the doctor in front of the cannot. For navigation of ships or airplanes, it is also inconvenient to sit directly in front of the LCD and bask in the sun. Especially when there are multiple displays, displays facing the viewer at different angles should have a wide range of viewing angles, or “understand what is being shown at a glance.” Consumer monitors do not meet this requirement because they use TwistedNematic viewing angles. In order to better adapt to industrial applications, the display is required to have a wide range of viewing angles. Currently, viewing Angle display technologies up to 178 degrees (such as ASV or MVA) have been developed.
