2023-08-04

capacitive touch screen is the use of contact sensors to make the screen on the conductor induced voltage, resulting in a relative current, through the distance to measure the touch point. In a low temperature environment, the water vapor content on the surface of the palm skin is low and the conductivity is poor, which affects the performance of the sensor, causing the industrial integrated machine to fail to recognize the touch position well and touch failure. The operating temperature of the capacitive touch screen is usually -5-60°C. If it is used in a low temperature environment, it is easily affected.

Compared with capacitive touch screens, temperature has less influence on resistive touch screens. Because of the different processes used, the micro-circuit on the touch screen is connected to work and is less affected by temperature. In addition, the technological level of the resistive touch screen is also more mature, and the materials used are more mature. The operating temperature of the resistive touch screen is required to be between -20-65°C, which can meet most of the use environment. The accuracy of the infrared touch screen is completely free from current, voltage and electrostatic interference, and the infrared touch screen is suitable for various light pollution environmental conditions. But the infrared touch screen because of its single sensor, easy to damage, aging, and touch interface can not withstand do not disturb, destructive, maintenance and so on. The static electricity generated during the use of infrared touch screen in low temperature environment is easy to absorb dust, which affects the use of industrial tablet computers. Infrared touch screen suitable for application in the field of aerospace.
