    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 display device controls a display by changing a reference value set in a foldable area of a display panel. The display device includes a display panel displays an image and outputs force sensing signals, and a controller that converts the force sensing signals into force values and controls the display when the force values in the foldable area of the display area are equal to or greater than a second reference value different from a first reference value.

    Abstract: A display device is provided. The display device includes: a display panel including a first area, a second area, and a folding area between the first area and the second area, and a force sensor at one surface of the display panel. The force sensor includes a plurality of first touch cells overlapping the first area or the second area, a plurality of second touch cells overlapping the folding area, and a touch driver which controls a threshold voltage of the plurality of second touch cells on the basis of an intensity of a base force of the plurality of second touch cells.
