ABSTRACT:
A flexible, non-birefringent cover and a polarizer on the front of a resistive touch panel reduce touch screen image distortion and obscuration resulting from the reflection of ambient light. Reduced reflection of ambient light is also obtained by touch screens of alternative construction incorporating combinations anti-reflection panels and polarizers located behind the touch panel.
