Self-tensioning membrane touch screen

摘要

A digitizer including a support structure defining a digitizer area and a spacer element; a tensioned membrane disposed in spaced relationship to the support structure on the spacer element; and a peripheral flexible member extending from the support structure and including at least two independently flexible sections attached to the membrane and pretensioned counter to the tension of the membrane for deflecting and maintaining tension on the membrane to sustain the spaced relationship with the membrane relative to the structure.
