Abstract
A touch sensor device includes first electrode patterns arranged in a first direction and physically separated first electrode cells; second electrode patterns arranged in a second direction crossing the first direction and includes physically separated second electrode cells; first touch signal lines connected to the first electrode cells; second touch signal lines connected to the second electrode cells; and a touch sensor controller connected with the first touch signal lines and the second touch signal lines. The first electrode cell and the second electrode cell adjacent in the first direction form a channel for generating position information by a mutual capacitive method. The touch sensor controller stores a ghost table including a ghost ratio for each channel for a touch position, and removes a ghost from measured touch data by using the ghost table to generate final touch data.
