Patent ID: 8547338

Claim:
A display device comprising: a display panel that comprises a plurality of pixels; a plurality of detection units formed in row and column directions in the display panel that generate an output signal based on a touch to the display panel; a detection signal processor that generates detection data based including row detection data and column detection data on the output signal; and a touch determination unit configured to determine whether the touch has occurred by comparing the detection data with a reference value including a row reference value and a column reference value, if the row detection data is greater than the row reference value and the column data is smaller than or equal to the column reference value, the touch determination unit is configured to change the row coordinate of the touch position and sustain a previous column coordinate, and if the column detection data is greater than the column reference value and the row data is smaller than or equal to the row reference value, the touch determination unit is configured to change the column coordinate of the touch position and sustain a previous row coordinate.
