Abstract:
A display deice capable of recognizing a uniform intensity of a touch regardless of a position of a touch input. The display device includes a display panel including a first area and a second area surrounding the first area, a plurality of pressure sensors disposed on the display panel, a dielectric layer disposed on the plurality of pressure sensors, and a bracket accommodating the display panel, the plurality of pressure sensors, and the dielectric layer. The dielectric layer forms a capacitance between the plurality of pressure sensors and the bracket. A first capacitance corresponding to the first area is smaller than a second capacitance corresponding to the second area.
