Touch input device

A touch input device comprising:

• a touch sensor comprising:
• a plurality of first touch electrodes,
• a plurality of second touch electrodes disposed to intersect with the plurality of first touch electrodes;
• a plurality of first pen electrodes each of which is disposed adjacent to each of the first touch electrodes;
• and
• a plurality of second pen electrodes each of which is disposed adjacent to each of the second touch electrodes, and
• a control unit which is configured to control the touch sensor, which is electrically connected to the plurality of first and second touch electrodes, and
• which is electrically connected to the plurality of first pen electrodes or the second pen electrodes;
• wherein each of the first touch electrodes includes:
• a pair of electrode portions, and
• wherein a first electrode portion of the pair of electrode portions is disposed adjacent to a partial touch electrode of at least one of the plurality of second touch electrodes,
• wherein a second electrode portion of the pair of electrode portions is disposed adjacent to remaining touch electrode of at least one of the plurality of second touch electrodes,
• wherein one end of the plurality of first pen electrodes is electrically connected to each other and one end of the plurality of second pen electrodes is electrically connected to each other,
• wherein the control unit is configured to control such that:
• a first drive signal is simultaneously applied to a first electrode portion of the first touch electrode, and
• a second drive signal is simultaneously applied to a second electrode portion of the first touch electrode, and
• wherein the second driving signal is a signal of a phase which is shifted phase of the first driving signal by 180 degrees.
