A touchscreen device utilizes digital scan to resolve a touch location with high precision. The touchscreen device includes touchells of about 3.175 mm by 3.175 mm (0.125 inches by 0.125 inches). An integrated circuit detects contacts in the touchells that resolve to touches on the touchscreen, and communicates those touches to a micro-controller via a serial bus. Silver epoxy interconnects for the tracks are reduced or eliminated. Multiple touchscreens having distinct touchell networks may be disposed to create a larger touchscreen area. Similarly, a single touchscreen may be divided quadrants, each with a distinct touchell network.
