Claim Text:
1. A display device comprising: a touch panel including a plurality of electrode columns, each electrode column including a plurality of electrodes positioned in the electrode column, the plurality of electrode columns including at least a first electrode column and a second electrode column that are adjacent to each other, the first electrode column and the second electrode column each including a first longitudinal edge and a second longitudinal edge where the second longitudinal edge of the first electrode column is adjacent to the first longitudinal edge of the second electrode column; a plurality of lines, each line connected to a corresponding electrode included in a corresponding one of the plurality of electrode columns; a display driving integrated circuit (IC) connected to the plurality of lines, the display driving IC for applying a touch scan signal to the plurality of electrodes of one or more electrode columns; and a touch IC for receiving a plurality of touch sense signals that are generated based on the touch scan signal from the plurality of electrodes; wherein lengths of the lines within the first electrode column increase as the lines within the first electrode column are positioned further from the first longitudinal edge of the first electrode column that is not adjacent to the first longitudinal edge of the second electrode column in a direction substantially perpendicular to a longitudinal direction of the lines of the first electrode column and towards the first longitudinal edge of the second electrode column; wherein lengths of the lines within the second electrode column decrease as the lines within the second electrode column are positioned further from the first longitudinal edge of the second electrode column in a direction substantially perpendicular to a longitudinal direction of the lines of the second electrode column and towards the second longitudinal edge of the second electrode column; wherein the touch IC determines a touch input based on the touch sense signals received from at least two adjacent electrodes in one of the electrode columns; wherein a line with a longest length from the first electrode column is directly adjacent to a line with a longest length from the second electrode column to minimize a difference in capacitance between the line with the longest length from the first electrode column and the line with the longest length from the second electrode column.
