Abstract
Disclosed herein is a touch sensor integrated type display device including gate lines; data lines; and pixel electrodes to which data signals are supplied through the data lines; touch/common electrodes; touch/common routing wirings connected to the touch/common electrodes to supply a common voltage and a touch driving signal; and dummy routing wires not connected to the touch/common electrodes. The common voltage is supplied to the touch/common routing wires and the dummy routing wires during a display operation period, and the touch driving signal is supplied to the touch/common routing wires and a load free driving signal is supplied to the dummy routing wires during a touch operation period.
Claims21
A touch sensor integrated type display device comprising:
- a plurality of gate lines;
- a plurality of data lines crossing over the plurality of gate lines;
- a plurality of pixel electrodes to which data signals are supplied through the plurality of data lines;
- a plurality of touch/common electrodes;
- a plurality of touch/common routing wires connected to the plurality of touch/common electrodes to supply a common voltage and a touch driving signal based on a time division method of time-dividing one frame period into a display operation period and a touch operation period;
- and
- a plurality of dummy routing wires transversing the plurality of touch/common electrodes and arranged in the same direction with the plurality of touch/common routing wires, the plurality of dummy routing wires not connected to the plurality of touch/common electrodes in an active area of the display device,
- wherein the common voltage is supplied to the plurality of touch/common routing wires during the display operation period, and wherein the touch driving signal is supplied to the plurality of touch/common routing wires and a load free driving signal is supplied to the plurality of dummy routing wires during the touch operation period.
A touch sensor integrated type display panel comprising:
- a plurality of gate lines and a plurality of data lines defining a plurality of pixel regions;
- a plurality of touch/common electrodes overlapping the plurality of pixel regions;
- a plurality of touch/common routing wires connected to the plurality of touch/common electrodes;
- and
- a plurality of dummy routing wires arranged in the same direction with the plurality of touch/common routing wires,
- wherein a common voltage is supplied to the plurality of touch/common routing wires during a display operation period of one frame period, and
- wherein a touch driving signal is supplied to the plurality of touch/common routing wires and a load free driving signal is supplied to the plurality of dummy routing wires during a touch operation period of the one frame period.
