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.

Eliminating interconnect induced inaccuracies and reducing scan time using a high granularity resistive touch screen

A method for reducing touch latency within a user interface of an aircraft display, the method including receiving, by a latency reduction unit, data from the aircraft display, where the data is of one or more data types, entering into one or more queues, by the latency reduction unit, the data based on the one or more data types, and sending, via a bus, the data asynchronously to a display processor of an aircraft display, where sending the data asynchronously includes transmitting the data by packets of data bits at an irregular rate.
