• Type :  capacitive touch screens consist of a glass panel with a capacitive (charge storing) material coating its surface. Unlike resistive touch screens, where any object can create a touch, they require contact with a bare finger or conductive stylus. When the screen is touched by an appropriate conductive object, current from each corner of the touch screen is drawn to the point of contact. This causes oscillator circuits located at corners of the screen to vary in frequency depending on where the screen was touched. The resultant frequency changes are measured to determine the x- and y- co-ordinates of the touch event. Capacitive type touch screens are very durable, and have a high clarity. They are used in a wide range of applications, from restaurant and POS use to industrial controls and information kiosks.

• Type :  resistive touchscreens respond to the pressure of a finger, a fingernail, or a stylus. They typically comprise a glass or acrylic base that is coated with electrically conductive and resistive layers. The thin layers are separated by invisible separator dots. When operating, an electrical current is constantly flowing through the conductive material. In the absence of a touch, the separator dots prevent the conductive layer from making contact with the resistive layer. When pressure is applied to the screen the layers are pressed together, causing a change in the electrical current. This is detected by the touchscreen controller, which interprets it as a vertical/horizontal coordinate on the screen (x- and y-axes) and registers the appropriate touch event. Resistive type touchscreens are generally the most affordable. Although clarity is less than with other touchscreen types, they're durable and able to withstand a variety of harsh environments. This makes them particularly suited for use in POS environments, restaurants, control/automation systems and medical applications.
