As industrial tablet computers become more and more popular in the market, the emergence of various industrial tablet computers is dazzling. It has brought serious troubles to everyone's purchase, causing many corporate purchasers to only pay attention to the price of industrial tablets and no longer pay too much attention to the products themselves. This is a very serious mistake. Industrial tablet computers are due to their industrial The environment is harsh and the performance requirements of the product are very high, so choosing a cheap industrial tablet computer is definitely not the best.

1. Brightness: Normal brightness, the brightness in indoor environment is 250~300cd/m2 and can be read under sunlight. If it is used outdoors, the brightness requirement is usually very high, usually 500~1000cd/m2.

2. Color. In some industrial applications, when the information expressed by color is more important than text and numbers, it is very important to measure the color as a percentage of NTSC color saturation for comparison. Currently, color saturation in LCD products The brightness mainly depends on the backlight. CCF is currently a very mainstream application technology, which can usually reach 70%-80% of the color saturation. If the color saturation is to be close to the full color saturation, the backlight is usually realized with LED technology.

3. Contrast ratio. Since users may not be viewing at the ideal distance and optimal lighting conditions, an LCD panel with a higher contrast ratio is the best choice. Generally, it is better to choose 450:1 or more for industrial applications.

4. Electrical performance viewing angle, usually multiple people may watch at the same time. Considering this situation, the LCD panel of industrial tablet computers is required to have a larger viewing angle than ordinary LCD panels. Usually industrial grade requires the maximum viewing angle (H )150/(V)145 or above.

5. Response time. The current response time of consumer computers is less than 30ms. In industrial applications, users are required to feel the movement in a dynamic environment, and the response time is usually less than 10ms.

6. Durable performance. Backlight life. Due to environmental effects and continuous use requirements in industrial applications, the life of a general CCF (cold cathode fluorescent lamp) is 40,000 hours. Availability ensures that failure and repair time are minimized and simplified, and the utilization rate is maximized. .

Industrial tablet computers have quickly occupied a certain market due to their good pressure resistance, fast and convenient installation operations, and beautiful appearance. Through these standards, you will have a certain understanding of industrial tablet computers, which will also make it easier for you to make better judgments in your selection.
