Dual touchscreen device calibration

Abstract:

A computing device is provided. The computing device comprises a first display device having a first capacitive touch sensor having a first current calibration map. The computing device further comprises a second display device having a second capacitive touch sensor. The computing device further comprises a processor configured to perform a first run-time calibration on the first capacitive touch sensor to generate a first calculated calibration map. The processor is further configured to perform a second run-time calibration on the second capacitive touch sensor to generate a second calculated calibration map. The processor is further configured to detect a replacement condition for the first calculated calibration map and replace the first current calibration map with the second calculated calibration map, such that the second calculated calibration map is utilized for the first capacitive touch sensor of the first display device.
