Abstract
A display device includes a display panel, a touch panel, and a digitizer. The digitizer includes a first electrode pattern layer, a first cover layer that is thermally deformable at a first thermal deformation temperature or higher, and a first intermediate layer located between the first electrode pattern layer and the first cover layer. The first intermediate layer is thermally deformable at a second thermal deformation temperature or higher. The second thermal deformation temperature is lower than the first thermal deformation temperature.
Claims15
A digitizer comprising:
- a first electrode pattern layer;
- a first cover layer thermally deformable at a first thermal deformation temperature or higher;
- a first intermediate layer located between the first electrode pattern layer and the first cover layer, the first intermediate layer being thermally deformable at a second thermal deformation temperature or higher,
- wherein the second thermal deformation temperature is lower than the first thermal deformation temperature;
- and
- a first adhesive layer located between the first electrode pattern layer and the first cover layer,
- wherein the first intermediate layer contacts the first electrode pattern layer and planarizes a step difference corresponding to the first electrode pattern layer by covering a height of the first electrode pattern layer, a portion of the first intermediate layer being below a top surface of the first electrode pattern layer,
- wherein the first adhesive layer is located between the first intermediate layer and the first cover layer,
- wherein the first electrode pattern layer, the first cover layer, the first intermediate layer, and the first adhesive layer have curved side portions,
- wherein the curved side portion of the first cover layer maintains elasticity to return to an original shape, and
- wherein the curved side portion of the first intermediate layer maintains a curved shape against the elasticity of the curved side portion of the first cover layer.
A display device comprising:
- a display panel;
- a touch panel located at a top of the display panel;
- and
- a digitizer located at a bottom of the display panel,
- wherein the digitizer comprises:
- a first electrode pattern layer;
- a first cover layer thermally deformable at a first thermal deformation temperature or higher;
- a first intermediate layer located between the first electrode pattern layer and the first cover layer, the first intermediate layer being thermally deformable at a second thermal deformation temperature or higher, wherein the second thermal deformation temperature is lower than the first thermal deformation temperature;
- and
- a first adhesive layer located between the first electrode pattern layer and the first cover layer,
- wherein the first intermediate layer contacts the first electrode pattern layer and planarizes a step difference corresponding to the first electrode pattern layer by covering a height of the first electrode pattern layer, a portion of the first intermediate layer being below a top surface of the first electrode pattern layer,
- wherein the first adhesive layer is located between the first intermediate layer and the first cover layer,
- wherein the first electrode pattern layer, the first cover layer, the first intermediate layer, and the first adhesive layer have curved side portions,
- wherein the curved side portion of the first cover layer maintains elasticity to return to an original shape, and
- wherein the curved side portion of the first intermediate layer maintains a curved shape against the elasticity of the curved side portion of the first cover layer.
