Selection method of industrial LCD screen
Date:2019-07-22
Industrial LCD is widely used in military industry, telecommunication, metallurgy, transportation, electric power, railway, aviation, communication, finance, network, medical treatment, machinery manufacturing, precision instruments and other fields. The R & D and procurement of these industries are emerging one after another in the LCD market. How to choose the right industrial LCD? Now let's share the selection method of industrial LCD screen?
1. What indicators should be paid attention to in the selection of industrial LCD screen
How to select suitable industrial LCD products is very important. When selecting the type, color, size and resolution, brightness and contrast, response time, viewing angle, storage and working temperature, relative temperature, signal and interface type and other general indicators of LCD, more attention should be paid to whether it is suitable for high and low temperature environment, sunlight visual performance The key indicators include waterproof and dust-proof grade, anti vibration ability, strong electromagnetic interference resistance, touch function support, touch screen type and interface, and the manufacturer's indicators such as product quality and repair rate, supply and service ability should also be paid special attention to.
2. Stability of industrial LCD
Industrial LCD usually needs to be used 24 hours a day, 365 days a year without interruption. The application environment of some displays may be worse, such as high temperature and humidity, low temperature environment, strong vibration, strong electromagnetic interference and other special environments, which requires higher reliability and stability of the display. In terms of design, the current, power consumption, temperature, anti-interference, electric shock ability and average time between failures of industrial LCD are much greater than those of ordinary LCD. At the same time, the industrial LCD must also use a fully shielded metal shell to ensure electromagnetic compatibility and anti-interference performance. In the selection of LCD central panel and even components, the industrial LCD uses professional industrial LCD panel, and the characteristics of components such as voltage, current, temperature and humidity are higher than those of ordinary display. In terms of the aging process requirements of components and whole machine, the requirements of industrial LCD are also higher. The aging of ordinary LCD is usually about 8 hours at room temperature, while the aging of industrial LCD needs more than 24 hours at high temperature and high humidity, so as to ensure the stability of the whole machine.
3. The difference between industrial LCD and ordinary LCD
LCD screens in industrial applications need to support clear and accurate visual effects from multiple angles in a strong light environment. Most industrial environments are surrounded by strong light, which poses a great challenge to the visibility of display. The difference between industrial LCD screen and ordinary display screen: the main difference is the working temperature range. The ordinary one is generally 0-50 degrees, and the general requirement of industry is - 30-80 degrees. Industrial LCD screen is used in industry, with a variety of display sizes and installation methods, etc. Unlike ordinary LCD screen, industrial screen can adapt to extreme environment, and has light, beautiful and practical box structure, multiple display sizes, support serial port and USB interface, use resistive touch screen and capacitive touch screen, and support VGA and AV signal input. Most industrial LCD screens are used in relatively harsh environment, However, ordinary commercial LCD is difficult to work in harsh environment. The former has better seismic performance, and can be used for a long time without any failure.
The selection method of industrial LCD screen is based on the above points. It is certain that customers will choose the most cost-effective industrial LCD screen.
