With the development of society and the advancement of technology, LCD screens can be seen everywhere in our lives. TVs, automobiles, cash registers, ordering machines, traffic stations, road signs, aerospace, etc., covering industrial, military, medical, automotive, electronics and other major industries, can be seen almost everywhere. LCD screens are divided into industrial LCD screens and ordinary LCD screens, so what is an industrial LCD screen? What are the features? How is it different from normal screen?
As the name implies, industrial LCD display is a display used for industrial automation control equipment, with a variety of display sizes and installation methods. The main difference between it and civilian or commercial display screens is that the shell design is generally all-steel design, and the panel structure is made of cold-rolled steel plate, electro-galvanized plate, stainless steel plate, hot-dip galvanized plate, die-cast aluminum and other materials, with dustproof, shockproof and High temperature resistance and other characteristics.
What is the difference between industrial LCD display and ordinary liquid crystal display? Due to its special material, industrial LCD display supports serial port and USB interface, can use resistive touch screen and capacitive touch screen, supports VGA and AV signal input, and has a light, beautiful and practical box structure, and various display sizes. Therefore, it can adapt to extreme environments and be used in relatively harsh environments, and it works stably and reliably. Ordinary LCD screens generally only work at a temperature of 0-50 degrees, which has higher environmental requirements and does not have industrial-grade resistance. Therefore, the industrial LCD liquid crystal display can be used in aerospace, laboratory and other places, and it can work for a long time. Ordinary LCD displays are generally used in homes and commercial places.
Industrial LCD display, the commonly used representative is the TFT technology liquid crystal screen, its brightness, contrast, power consumption, life, volume and weight and other comprehensive performance fully catch up with and exceed the CRT display device, its performance is excellent, large With good scale production characteristics, high degree of automation, low cost of raw materials, and broad development space, it is the mainstream display product in the 21st century and a bright spot of global economic growth.
Industrial LCD display has a wide range of applications in our daily life, such as automotive electronics, medical beauty, household appliances, instrumentation, industrial control power, military aerospace, measuring instruments, and digital communications. etc. So, what should be paid attention to when using industrial LCD display?
1. Industrial LCD liquid crystal display, there are resistive liquid crystal screen and capacitive liquid crystal screen, and touch screen series. Then when using a capacitive industrial LCD screen, it is necessary to correctly install the driver of the capacitive industrial LCD screen according to the instructions.
2. When using a resistive industrial LCD screen, if you find that the cursor cannot move or can only move in a local area, you can check whether the touch area of the touch screen is pressed by other touch objects. For example, once the touch screen is pressed by the display shell or the cabinet shell, it is equivalent to a point that has been touched all the time, then the coordinate position feedback to the controller will be inaccurate, and the lighting will not be accurate. If you press the cabinet shell on the touch area, you can slightly adjust the distance between the cabinet and the display. If you press the display case on the touch area, you can try to loosen the display case screw a little bit.
3. In order to ensure the normal operation of the industrial LCD screen system, in addition to ensuring the correct installation of the system software, it is also necessary to remember not to install two or more touch screen drivers on one host computer, which will easily cause the system to fail. A conflict occurs during operation, so that the industrial LCD screen system cannot be used normally.
Industrial LCD mainly has the characteristics of dustproof, shockproof and high temperature resistance, and its good material can adapt to various harsh environments. In the process of installation and operation, we must also follow strict operating procedures to ensure the good operation of the LCD screen system.
