Analysis Of Advantages And Disadvantages Of Capacitive Touch Screen And Infrared Touch Screen

The capacitive screen works with human body current sensing.
Advantages: high sensitivity, no need to press hard, good permeability
Disadvantages: high cost; in the humid high temperature environment will cause the capacitive screen drift, resulting in inaccuracies.
The infrared screen is composed of infrared emitting and receiving sensing elements mounted on the outer frame of the touch screen. On the surface of the screen, an infrared detecting net is formed, and any touch object can change the infrared rays on the contacts to realize the touch screen operation.
Advantages: cheap, suitable for large size, good explosion-proof performance, can be touched by any object, completely closed and maintenance-free, adapt to harsh environment
Disadvantages: poor stability, may be affected by light
