Abstract
A method of determining a touch coordinate in a touch panel includes detecting a touch cell among a plurality of touch cells, wherein the plurality of touch cells are defined by a plurality of areas in the touch panel in which a first touch electrode and a second touch electrode overlap with each other, detecting a touch position in the detected touch cell based on a first electrical signal measured at least one of a plurality of terminals of the first and second touch electrodes, determining a number of touches based on a distance between a first touch and a second touch, determining expected touch coordinates corresponding to the number of touches, and determining the touch coordinate based on a second electrical signal measured at least one of the plurality of terminals of the first and second touch electrodes and the expected touch coordinates.
