Abstract
A display device may include a first substrate, a touch sensor disposed on the first substrate, a second substrate disposed on the touch sensor, and a display unit disposed on the second substrate and which displays an image. The touch sensor includes a piezoelectric device, which senses a touch thereon, and an adhesive layer, which attaches the first and second substrates to each other. The piezoelectric device and the adhesive layer are disposed in a same layer.
Claims19
A display device, comprising:
- a first substrate;
- a touch sensor disposed on the first substrate;
- a second substrate disposed on the touch sensor;
- and
- a display unit disposed on the second substrate and which displays an image;
- wherein the touch sensor comprises a piezoelectric device, which senses a touch thereon, and an adhesive layer, which attaches the first and second substrates to each other,
- an entirety of the piezoelectric device and an entirety of the adhesive layer are disposed on the first substrate and have a same thickness as each other defining a same layer,
- wherein the touch sensor further comprises a first signal line and a second signal line, which are connected to the piezoelectric device, and
- wherein the first and second signal lines are disposed in the same-layer as the piezoelectric device.
6 more elements
A display device, comprising:
- a housing including a contact member;
- and
- a display module coupled to the housing and spaced apart from the contact member by a predetermined distance,
- wherein the display module comprises a folding region, a first non-folding region adjacent to the folding region, and a second non-folding region, wherein the folding region is interposed between the first non-folding region and the second non-folding region,
- wherein the display module further comprises:
- a first substrate;
- a touch sensor disposed on the first substrate and in the folding region;
- and
- a second substrate disposed on the touch sensor, wherein the touch sensor comprises:
- a piezoelectric device, which senses an external pressure;
- and
- an adhesive layer, which attaches the first and second substrates to each other,
- wherein an entirety of the piezoelectric device and an entirety of the adhesive layer are disposed on the first substrate and have a same thickness as each other defining a same layer,
- wherein the touch sensor further comprises a first signal line and a second signal line, which are connected to the piezoelectric device, and
- wherein the first and second signal lines are disposed in the same layer as the piezoelectric device.
