The application of touch screen technology in industrial control - industrial touch screen is an intelligent interface that connects human and machine through touch industrial display. It is an intelligent operation display terminal instead of traditional control button and indicator lamp. It can be used to set parameters, display data, monitor the status of equipment, and describe the automatic control process in the form of curve/animation. It is more convenient, faster, more expressive and can be simplified to create a friendly man-machine interface for the powerful touch screen of PLC control program. Touch screen, as a special computer peripheral, is the simplest, convenient and natural way of human-computer interaction at present. It gives multimedia a brand-new look and is an attractive new multimedia interactive device.

            Industrial control touch screen is mainly small and medium size, which requires high stability, waterproof, explosion-proof, dust-proof and other requirements of touch screen. The inadequacy of traditional resistance screen, water-proof infrared screen and poor dust-proof makes the advantages of capacitance leap forward. In addition to the general advantages of ordinary capacitive screens, the capacitive touch products with XT board cards also have unique personalized advantages that are more suitable for industrial touch screens: strong penetration (the thickest glass can penetrate 12 mm), large area waterproof, handcuffs can also be touched, and can also be freely switched between single point and multi-point.
