What are they?
Think of an iPad or iPhone and you're thinking of a touch screen. These devices changed the way we use phones and computers by getting rid of physical controls and replacing them with a screen you could control by touching virtual keys and buttons.A touch screen panel is coated with a thin metallic electrically and resistive layer that causes a change in the electrical current when touched, which is registered as a 'touch event' and sent to the controller for processing. You can use a touch screen as an alternative to a mouse or touch pad.
Types of Touch screens
Different types of Touch Sreens?
Resistive-type screens lack the clarity of other touch screens but they tend to be very durable and can be used in a variety of environments.
Capacitive screens are resistant to outside elements.Unlike resistive and surface wave screens, which can be used with stylus, capacitive panels must be touched with a finger.
Surface wave touch panels are the more advanced of the three types, offering the highest clarity. But they are more easily damaged by outside elements.
