TOUCH SENSOR STRUCTURES FOR DISPLAYS

摘要

An electronic device may have a touch screen display. The display may have a touch sensor structure that determines the location at which external objects touch the display. The touch sensor structure may have a clear substrate on which conductive capacitive touch sensor electrodes are formed. The electrodes may be formed from a transparent conductive material such as indium-tin oxide. The clear substrate may be formed from a flexible material such as a polymer. The polymer may be a clear polyimide. Copper traces or other conductive traces may be used to route sensor signals from the capacitive touch sensor electrodes to processing circuitry in the electronic device.
