Industrial flat panel computer LCD monitors are used in industry, and their performance is relatively stable. What other features are there? What factors should companies consider when buying? Let's take a look together.
What are the characteristics of industrial tablet LCD monitors
Its main principle is to use electric current to stimulate liquid crystal molecules to produce dots, lines, and surfaces to form a picture with the lamp on the back.
1. Thin body and space saving: Compared with the more bulky CRT monitor, the LCD monitor only needs one-third of the space of the former.
2. Power saving, no high temperature: It is a low power consumption product, which can be completely non-hot. Compared with CRT monitors, high temperature is unavoidable due to imaging technology.
3. No radiation, good health: The LCD is completely free of radiation, which is a boon for people who work in front of the computer all day.
Fourth, the screen is soft and does not hurt the eyes: Unlike CRT technology, the LCD screen will not flicker, which can reduce the damage to the eyes of the display and make the eyes less fatigued.

1. Size: 15 inches is the most popular choice, but in recent years, 17 and 19 inches have become popular. If you are only dealing with word work or surfing the Internet, 15 inches will meet your needs. If you are engaged in computer graphics and video editing, a larger size is more suitable.
2. Viewing angle: For 15-inch and 17-inch displays, most of them are used by one person, so a vertical viewing angle of 120 degrees is sufficient. For 18 inches or more, 150 degrees or more is required. Many ViewSonic machines use special technology to achieve a 170-degree viewing angle.
3. Contrast ratio: Generally speaking, the larger the contrast ratio, the better. As far as current technology is concerned, the most basic contrast ratio of the brightness of liquid crystal displays of all sizes should be 400:1.
4. Brightness: 250nits brightness is enough for people who use computers to handle paperwork; if you often play computer games, watch digital discs (DVD) or TV, then you must choose 450nits brightness.
5. Response time: The response time is at least less than 40 milliseconds (ms) before the dynamic image of the shadow will appear. As far as the current product is concerned, a color LCD with a response time of less than 25 milliseconds should be one of your basic considerations. However, if you are watching animated videos or playing online games, it is recommended to choose a model with a 16ms response time.
6. Bright spots: There is no certain standard on the market, but there should be no more than 5 bright spots for each color liquid crystal display.
