主权项 1. A display device, comprising: a touch screen configured to operate as an electromagnetic touch mode or a capacitive touch mode based on a touch type of an input touch signal, the touch screen comprising: a plurality of sensing electrode lines arranged to be separated from each other in a first direction;a plurality of driving electrode lines arranged to be separated from each other in a second direction intersecting the first direction, the plurality of driving electrode lines being further arranged to be physically separated from the plurality of sensing electrode lines;a switch control unit configured to control a plurality of first switches and a plurality of second switches, based on a determination of whether the touch type of the input touch signal is either electromagnetic or capacitive,wherein, only after when the touch type is determined to be electromagnetic: the plurality of first switches are configured to control connection of pairs of sensing electrode lines among the sensing electrode lines by turning on or off, such that the pairs of sensing electrode lines are respectively connected together, andthe plurality of second switches are configured to control connection of pairs of driving electrode lines among the driving electrode lines by turning on or off, such that the pairs of driving electrode lines are respectively connected together, andwherein, only after when the touch type is determined to be capacitive: the plurality of first switches are configured to control connection of pairs of sensing electrode lines among the sensing electrode lines by turning on or off, the pairs of sensing electrode lines are respectively disconnected from each other, andthe plurality of second switches are configured to control connection of pairs of driving electrode lines among the driving electrode lines by turning on or off, such that the pairs of driving electrode lines are respectively disconnected from each other.
