The industrial touch screen all-in-one machine has extremely high requirements for its performance due to its application in harsh environments such as high and low temperature, dust, water, and oil stains. Especially in the high and low temperature environment, it is a great challenge for industrial touch screen products. Then, the high and wide temperature performance of the industrial touch screen is very necessary.
What is the temperature adaptation range of the industrial touch screen all-in-one touch screen, and will the high temperature environment have any impact on the touch screen? Let's take a look at the adaptation of different touch screens to temperature.
Common industrial touch screens are generally divided into resistive touch screens, capacitive touch screens and infrared touch screens.
Infrared touch screen
The accuracy of the infrared touch screen is completely free from current, voltage and static interference, and the infrared touch screen is suitable for various light pollution environmental conditions. However, the infrared touch screen is vulnerable to damage and aging due to its single sensor, and the touch interface cannot withstand undisturbed, destructive, and complicated maintenance. In the low temperature environment, the static electricity generated by the infrared touch screen during use is easy to absorb dust, which in turn affects the use of industrial tablet computers. The infrared touch screen is suitable for the aerospace field.
Resistive touch screen
Compared with capacitive touchscreens, temperature has less effect on resistive touchscreens. Because of the different processes used, the touch screen is connected to work through the miniature circuit, which is less affected by the temperature. The technology level of the external resistive touch screen is also more mature, and the materials used are all tested. The operating temperature of the resistive touch screen is between 20 degree -65 degree , which can meet most usage environments.
capacitive touch screen
The capacitive touch screen uses a touch sensor to generate an induced voltage on the conductor on the screen, thereby generating a relative current, and measuring the touch point by distance. In a low temperature environment, the water vapor content of the palm skin surface is low and the conductivity is poor, which affects the performance of the sensor, causing the industrial tablet computer to not recognize the touch position well and the touch failure. The operating temperature of capacitive touch screens is usually 5 degree -60 degree . If it is used in a low temperature environment, it is easily affected.
In summary, the working environment temperature that three common different touch screens can adapt to, and the analysis of the advantages and disadvantages of various touch screens, please consult the official website of Shenzhen YONGS Technology Co., Ltd. for more information.
