1. A display apparatus, comprising:
- a display panel configured to display a first image every frame period in a two-dimensional (2D) mode, and display a second image every frame period in a three-dimensional (3D) mode;
a barrier panel disposed on the display panel and comprising a plurality of first electrodes extending in a first direction and arranged in a second direction crossing the first direction, a plurality of second electrodes extending in the second direction and arranged in the first direction, and a liquid crystal layer disposed between the first and second electrodes, wherein the barrier panel forms a barrier pattern configured to separate the second image into a left eye image and a right eye image;
a touch sensing part comprising a plurality of third electrodes disposed on the second electrodes, extending in the first direction, and arranged in the second direction, wherein the third electrodes are capacitively coupled to the second electrodes; and
a coordinate calculator configured to detect a variation of a capacitance between the second electrodes and the third electrodes, and calculate coordinate information of a touch point.

Abstract
A display apparatus includes a display panel that displays a second image in a 3D mode, a barrier panel that forms a barrier pattern that separates the second image into a left-eye image and a right-eye image, a touch sensing part that includes third electrodes capacitively coupled to a portion of the electrodes included in the barrier panel, and a coordinate calculator. The coordinate calculator measures a variation of capacitance between the portion of the electrodes included in the barrier panel and the third electrodes.
