1. A touch sensing module comprising:
first driving electrodes arranged in parallel;
first sensing electrodes intersecting the first driving electrodes;
second driving electrodes on a rear side of the first driving electrode with a touch insulating layer therebetween such that they are associated with the first driving electrodes, respectively;
second sensing electrodes on a rear side of the first sensing electrodes with the touch insulating layer therebetween such that they are associated with the first sensing electrodes, respectively;
driving switching circuits electrically connecting the second driving electrodes to the first driving electrodes, respectively, or to a low-level voltage source; and
a touch driver circuit configured to supply touch driving signals to the first driving electrodes and to detect touch sensing signals through the first sensing electrodes to detect touch position coordinates.
