Capacitive touch screen
Capacitive touch screens are becoming popular as they are user-friendly devices, which everyone can easily interact with. A Capacitive touch screen is a tactile display, made up of a glass panel and/or a plastic panel put over a capacitive layer with static charge, which allows users to interact directly with the graphic interface of the OS by simply touching it with fingers, therefore the use of other input devices turns to be useless.
This new technology replaces the mouse or other peripheral devices and therefore it promotes a more direct contact between man and machine.
The application areas are: medical industry, information terminals, retail and restaurant systems, appliances, consumer electronics, financial applications, telecommunications, automotive industry, security systems, fitness industry, agriculture and many others.
The advantages of capacitive TS are: durability, optical clarity up to 90%, resistance to dirt, grease and moisture, excellent tactile feedback, easy to clean, very light finger touch for activation, fast response time. They are often used together with membrane switches enabling a very easy interaction with the device.
