Touch detection device and display device including the same

A display device comprising:

• a display panel;
• and
• a touch detection device including a touch area overlapping at least a portion of the display panel, wherein the touch detection device includes:
• the touch area including a plurality of driving electrodes and a plurality of detecting electrodes crossing the plurality of driving electrodes;
• a plurality of touch driving ICs electrically connected to the plurality of driving electrodes and supplying driving signals to the plurality of driving electrodes;
• a plurality of touch detecting ICs electrically connected to the plurality of detecting electrodes and receiving touch detection signals from the plurality of detecting electrodes;
• and
• a touch control IC controlling the plurality of touch driving ICs and the plurality of touch detecting ICs, and wherein:
• the touch area is divided into a plurality of sub-touch areas,
• the plurality of touch driving ICs are provided to correspond to the plurality of sub-touch areas, respectively, and
• the plurality of touch detecting ICs are provided to correspond to the plurality of sub-touch areas, respectively.

A display device, comprising:

• a plurality of detecting integrated circuits (ICs) coupled to a respective plurality of sub-touch areas;
• and
• a processor configured to determine that a touch input has occurred on one of the sub-touch areas, wherein:
• each of the plurality of detecting ICs is configured to output an analog touch signal generated by a first electrode of a corresponding one of the sub-touch areas, and
• the processor is configured to:
• convert the analog touch signal generated from each of the sub-touch areas to digital touch sensing data, and
• determine that touch input has occurred based on the digital touch sensing data.
