DISPLAY DEVICE

摘要

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.
