Abstract: A display device includes a first display substrate, which provides an input surface and includes a blocking area and a plurality of opening areas, and first and second touch sensors disposed in the blocking area. The first touch sensors receive different scan signals according to an operation mode thereof. The second touch sensors output first sensing signals on the basis of a variation in capacitance in a first operation mode and output second sensing signals according to a resonant frequency of an input device in a second operation mode.

Abstract: An optical touch system includes: a coordinate processor; a display device; and an optical element. The optical element is configured to emit light towards the display device and provide information about reflected light corresponding to a portion of the emitted light to the coordinate processor. The display device includes: a display panel configured to display an image, a touch substrate disposed on the display panel, the touch substrate including optical recesses each configured to reflect respectively different amounts of incident light, and a protective layer disposed on the touch substrate. The coordinate processor is configured to determine a touch or near-touch coordinate based on the information received from the optical element.
