Devices and methods for controlling both LED and touch sense elements via a single IC package pin

A touch-sensitive light emitting diode (LED) display device, comprising:

• at least one LED matrix including a plurality of LED elements arranged into N columns;
• at least one first touch sense element;
• a counter adapted to provide at least one indication of count values of a first count ranging from zero to N+1;
• a controller integrated in an integrated circuit (IC) and coupled to the N columns of the LED matrix and the at least one first touch sense element via a first input/output pin and configured to, during a first time period based on a first N count values of the first count, sequentially communicate via the input/output pin with LED elements of each of the N columns and, during a second time period based on an N+1 count value of the first count, communicate via the input/output pin with the at least one first touch sense element.

A touch-sensitive display device, comprising:

• display means for displaying at least one visual indication;
• detection means for detecting at least one touch-based command;
• and
• control means integrated in an integrated circuit (IC) and coupled to the display means and the detection means via a single input/output pin of the IC package for communicating with the display means via the input/output pin and for communicating with the detection means via the input/output pin.
