Abstract

An exemplary touch panel module includes a touch panel, a supporting body, a plurality of first elastic members sandwiched between the touch panel and the supporting body, and a plurality of displacement sensors mounted on the supporting surface. The touch panel includes a touch surface, and a reflection surface opposite to the touch surface. The supporting body includes a supporting surface facing the reflection surface. Each first elastic member is deformable along a direction substantially perpendicular to the touch surface. Each displacement sensor is configured for sensing deformation of the corresponding first elastic member.
