    Abstract: A force sensor includes: a plurality of touch cells comprising a plurality of driving electrodes, a pressure sensing layer overlapping the driving electrodes, and a plurality of sensing electrodes overlapping the pressure sensing layer; and a touch driver configured to receive a raw data from the plurality of touch cells and to detect a touch pressure applied to the plurality of touch cells. The touch driver includes: a filtering unit configured to filter the raw data and to output sensing data; a data storage unit configured to store max data having the highest value from among the sensing data and propagation data of at least one adjacent touch cell adjacent to a max touch cell having the max data; and a noise removing unit configured to detect and remove noise from the sensing data.

    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 three 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.
