Touch screen controllers are integrated circuits that provide an interface between the touch screen sensor array and the device the screen operates. The controller receives position information from the sensor array which is usually resistive or capacitive. In turn, the position information is passed along to a microcontroller via a serial, parallel, USB, or UART interface.
