Resistive Touchscreen
Resistive touchscreens are composed of two flexible sheets coated with a resistive material and separated by an air gap or microdots. When contact is made to the surface of the touchscreen, the two sheets are pressed together, registering the precise location of the touch. Because the touchscreen responds to pressure on its surface, contact can be made with a finger or any other pointing device.
Resistive touchscreens typically have high resolution (4096 x 4096 DPI or higher), providing accurate touch control.
