Display device having a touch screen and method of driving the same

摘要

A display device including a touch screen and method of driving the same are provided. In a method of driving display device including a touch screen, the display device including a panel including a plurality of gate lines, and a plurality of electrodes respectively corresponding to the plurality of gate lines, the method includes: applying, by a display driving unit, a gate signal to a subset of the plurality of gate lines, applying, by a touch sensing unit: a common voltage to a first subset of the plurality of electrodes corresponding to the subset of the plurality of gate lines, and the touch scan signal to a second subset of the plurality of electrodes, other than the first subset of the plurality of electrodes.

1. A display device comprising a touch screen, comprising:
a panel, comprising:
a plurality of gate lines;a plurality of data lines;a plurality of electrodes grouped into n groups in a direction in which the plurality of gate lines extend, where n is an integer equal to or greater than 2; anda plurality of wires, each of the plurality of wires being respectively directly connected to one of the plurality of electrodes, such that a number of the plurality of wires is the same as a number of the plurality of electrodes; a display driving unit configured to:
apply a gate signal to the plurality of gate lines; andapply a data signal to the plurality of data lines; and a touch sensing unit configured to:
apply a common voltage or a touch scan signal to the plurality of electrodes respectively through the plurality of wires; andapply the touch scan signal to at least one group, among the n groups of the plurality of electrodes, other than a group, among the n groups of the plurality of electrodes, corresponding to gate lines to which the gate signal is applied,wherein the plurality of electrodes in each of the n groups are electrically isolated from each other, andwherein the common voltage or the touch scan signal is individually applied directly to each of the plurality of wires to respectively reach each of the plurality of electrodes in each of the n groups.
