What are the functional features of the industrial lcd LCD?
December 20, 2022
With the development of society and the progress of science and technology, LCD monitors have become ubiquitous. TVs, cars, cash registers, ordering machines, transportation stations, road signs, aerospace, etc., covering industrial, military, medical, automotive, electronic and other industries, almost everywhere. There are two kinds of LCD monitors: industrial LCD monitors and ordinary LCD monitors. What is an industrial LCD monitor? What are the functional features? What is the difference between ordinary screens?
Industrial LCD liquid crystal display as one of the industrial automation control equipment, its display size and installation methods are various. The main difference between it and civil or commercial displays is that the shell design is generally all-steel, and the panel structure is made of cold-rolled steel plate, electro-galvanized plate, stainless steel plate, hot-dip galvanized plate, die-cast aluminum, etc., which is dustproof, shockproof and high temperature resistant.
The industrial LCD display is made of special materials, supports serial port and USB interface, can adopt resistive touch screen and capacitive touch screen, supports VGA and AV signal input, has a lightweight, beautiful and practical box structure, various display sizes, can adapt to polar environment, relatively harsh use environment, stable and reliable work. But at the same time, the price of this display is generally more expensive. Only a few domestic manufacturers can produce, such as Shenzhen Jinghai Optoelectronics. But ordinary LCD, working temperature is only between 0-50 degrees, high environmental requirements, does not have industrial grade resistance. Therefore, industrial LCDs can be used in aerospace, laboratories and other places for a long time. Ordinary LCD displays are generally used in homes and commercial places.
Industrial LCD liquid crystal display, in our daily life, has a wide range of applications, automotive electronics, medical beauty, household appliances, instrumentation, industrial power, military aerospace, metrology, digital communications, etc.. So, what should be noted when using industrial LCD displays?
1 when using resistive industrial LCD, if the cursor can not move or can only move in the 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 enclosure or cabinet enclosure, it is equivalent to the point that has been touched, so the controller's coordinate position feedback will be inaccurate, and the light will be inaccurate. If you press the memory module on the touch area, you can slightly adjust the distance between the memory module and the display. If you press the display frame on the touch area, you can try to slightly loosen the screws of the display frame.
2 in order to ensure the normal operation of the industrial LCD display system, in addition to the correct installation of the system software, you must also remember not to install two or more touch screen drivers on the host computer, which can easily cause conflicts in the operation of the system, so that the industrial LCD display system can not be used under normal circumstances.
3 the industrial LCD, including resistive LCD, capacitive LCD and touch screen series. Then in the use of capacitive industrial LCD screen, you need to follow the instructions to correctly install the capacitive industrial LCD driver.
Industrial LCD liquid crystal display screen is dustproof, shockproof and high temperature resistant. Its excellent material can adapt to various harsh environments. During the installation and operation, the operating procedures should also be strictly followed to ensure the good operation of the LCD display system.
