Technical Examples

The present invention provides a way to measure and track non-linear corrections in touchscreens. Some or all of the relevant non-linear corrections may be determined automatically. Production floor test equipment may make electronic measurements, compute parameters, and load the parameters in non-volatile memory of the controller electronics. Alternatively, the controller electronics can make the electronic measurements and determine non-linear parameters. The latter embodiment of the invention permits the determination of non-linear parameters in the field, dynamically tracking changes in the non-linear characteristics of installed touchscreens that occur over time or due to environmental conditions.
