<p>Disclosed herein is a pressure sensor for a touch panel, including a signal input member configured to have conductors patterned thereon in an interdigitated form on a substrate, wherein conductor patterns on one side of the signal input member are formed in parallel in a comb pattern and connected on the lower part, and conductor patterns on the other side of the signal input member are formed in parallel in a comb pattern, connected on the upper part, and arranged in such a way as to be interdigitated with the conductor patterns on the first side, spacers disposed at top and bottom corners in which the conductor patterns are not formed on the substrate of the signal input member, a left support disposed in some region of a corner on the left side in which the conductor patterns are not formed on the substrate of the signal input member, a right support disposed in some region of a corner on the right side in which the conductor patterns are not formed on the substrate of the signal input member, a piezo film disposed on the spacers and the left and right supports, spaced apart from the signal input member, and configured to have a resistance value varied depending on an amount of pressure applied to the piezo film, and pressure supplement units disposed between the piezo film and the signal input member and disposed under regions of the piezo film to which inputs of keys having a greater width than other keys are transferred.</p> |
