Switchable touch stereoscopic image device

A switchable touch stereoscopic image device, comprising:

• a stereoscopic image generating module, comprising:
• a first substrate having a top surface;
• a second substrate, disposed corresponding to the first substrate, wherein the second substrate has a top surface and a bottom surface facing the top surface of the first substrate;
• a plurality of driving electrodes, disposed on the top surface of the first substrate;
• and
• a common electrode, disposed on the bottom surface of the second substrate;
• a light-path converting layer, disposed between the first substrate and the second substrate;
• and
• a touch sensing module, disposed on a side of the second substrate of the stereoscopic image generating module, the touch sensing module comprising:
• a third substrate facing the second substrate, wherein the third substrate has a bottom surface facing the top surface of the second substrate;
• an elastic medium layer, disposed between the second substrate and the third substrate, wherein the elastic medium layer is deformable by pressing:
• and
• a plurality of sensing electrodes disposed on the bottom surface of the third substrate;
• wherein a gap between the sensing electrodes and the common electrode is changed due to a deformation of the elastic medium layer when the third substrate is pressed.
