Touch-screen assembly with rigid interface between cover sheet and frame

摘要

A touch-screen assembly for performing pressure sensing or force sensing is disclosed. The touch-screen assembly includes a cover sheet having touch-sensing capability and a frame having an upper surface portion. Spaced-apart adhesive islands are disposed between the cover sheet and the upper surface portion of the frame. The adhesive islands serve to secure the cover sheet to the frame and have a Young's modulus of greater than 1 MPa so that the energy associated with the touching force is not absorbed by the adhesive island. This makes for more accurate pressure-based or force-based touch sensing.
