Abstract
The invention discloses a touch sensing device, which includes a containing space, a first substrate layer, a second substrate layer, a driver, and a sensor. The first substrate layer and the second substrate layer define the containing space for containing a fluid. The driver can provide charges to a first conducting layer of the first substrate layer, a second conducting layer of the second substrate layer, and the fluid. The sensor can sense the electric characteristics of the fluid. When a point unit approaches the touch sensing device and influences the charges, the appearance of the fluid could be changed and then the electric characteristics could also be changed.
