Abstract:
Devices and methods for minimizing a number of I/O pins needed to control LED and touch sense operations are described and disclosed herein. In an embodiment, a method comprises controlling at least one light emitting diode (LED) element via a single pin, and controlling at least one touch sense element via the single pin. In an embodiment, a touch-sensitive light emitting diode (LED) display device comprises at least one LED element, at least one touch sense element, and a controller integrated in an integrated circuit (IC) and coupled to the at least one LED element and the at least one touch sense element via a single pin. The controller is configured to communicate via the pin with the at least one LED element and the at least one touch sense element.
