Claim:
1. A touch sensor device, comprising: a plurality of columns, each column extending in a first direction and comprising: a touch sensor controller electrically connected with the first touch signal lines and the second touch signal lines, wherein: the first electrode patterns, the second electrode patterns, the first touch signal lines, and the second touch signal lines are disposed on the same layer; a first electrode of the first electrodes and a second electrode of the second electrodes adjacent to each other in a second direction crossing the first direction and disposed in a same column form a channel for generating position information by a mutual capacitive method; the touch sensor controller is configured to store a ghost table comprising a ghost ratio for each channel for a touch position for each column, and is further configured to remove a ghost from measured touch data by using the ghost table to generate final touch data; and the ghost is generated between adjacent columns of the plurality of columns.
