Abstract: A touch sensor includes a pressure sensor configured to become compressed along a first axis in response to a touch input into a touch area and a controller. The controller is configured to calculate a position of the touch and an intensity of the touch by using a detection signal obtained from the pressure sensor. The controller is further configured to calculate a first position, which has a greatest value of compression of the pressure sensor along the first axis, and calculate a position of the touch by correcting the first position by a first correction value corresponding to the greatest value of compression.

Abstract: A force sensor includes first and second substrates. The second substrate faces the first substrate. A driving electrode is disposed on a first surface of the first substrate facing the second substrate. A sensing electrode is disposed on the first surface of the first substrate and is spaced apart from the driving electrode. A force sensitive layer is disposed on a first surface of the second substrate, facing the first substrate. The driving electrode includes a main driving protrusion that protrudes from a side surface of the driving electrode, facing the sensing electrode.

Abstract: A display device includes a display panel and a force sensor. The force sensor is disposed adjacent to a first edge of the display panel and extends along the first edge. The force sensor includes a first sensing region, a second sensing region, a first force concentration bump, and a second force concentration bump. The second sensing region is located on a side of the first sensing region and has a larger area than the first sensing region. The first force concentration bump overlaps the first sensing region. The second force concentration bump overlaps the second sensing region and is spaced apart from the first force concentration bump.
