Abstract
A method of identifying a crack in a touchscreen display system includes measuring a distance between a first layer of the touchscreen display system and a second layer of the touchscreen display system, detecting a change in the distance at a portion of the touchscreen display system, identifying a crack in the first layer at the portion of the touchscreen display system based on the change in the distance, and adjusting one or more parameters of the touchscreen display system based on the crack in the first layer.
