TOUCH SCREEN SHIELD
20230229200 · 2023-07-20 ·

A shield that is attachable to a touch sensitive screen is disclosed. The shield may be attached to the touch sensitive screen only at its outer peripheral portion. An air gap is enclosed between the shield and the touch sensitive screen to form a planar air bearing. The shield preferably does not touch the active area of the touch sensitive screen when the user is not touching the shield but only viewing the touch sensitive screen through the shield. This mitigates unwanted optical artifacts such as trapped air bubbles, Newton rings and chromatic interference while maintaining the sensitivity of the touch sensitive screen.
