Abstract
A display device may include a display panel, a window member provided above the display panel, a housing accommodating the display panel and the window member and including at least one protrusion on an inner surface thereof, and a pressure sensor including a first conductive layer provided on the at least one protrusion and a second conductive layer provided at a peripheral area of the first conductive layer to be spaced apart from the first conductive layer.
Claims19
A display device, comprising:
- a display panel;
- a window provided above the display panel;
- a housing accommodating the display panel and the window and including at least one fixed protrusion on an inner surface thereof;
- and
- a pressure sensor including a first conductive layer provided on the at least one fixed protrusion and a second conductive layer provided at a peripheral area of the first conductive layer to be laterally spaced apart from the first conductive layer not to overlap the first conductive layer in a plan view,
- wherein the first conductive layer and the second conductive layer constitute a first electrode and a second electrode of the pressure sensor for sensing pressure responsive to vertical displacement of the second conductive layer relative to the first conductive layer upon applied pressure thereof to the second conductive layer to develop variable capacitance for the pressure sensor between the first electrode and the second electrode.
