Abstract
A display device includes a window on which a fingerprint detection region in which fingerprint information is detected is defined, an optical layer disposed below the window and in which at least one transmission hole overlapping the fingerprint detection region is defined, a protection layer disposed below the optical layer, and a sensor. A refractive index of the protection layer is greater than a refractive index of the window. A distance from the optical layer to the window is less than a distance from the optical layer to the sensor.
Claims20
A display device, comprising:
- a window on which a fingerprint detection region in which fingerprint information is detected is defined;
- an optical layer disposed below the window and in which at least one transmission hole overlapping the fingerprint detection region is defined;
- a protection layer disposed below the optical layer,
- wherein a refractive index of the protection layer is greater than a refractive index of the window;
- and
- a sensor disposed below the protection layer and overlapping the fingerprint detection region,
- wherein a distance from the optical layer to the window is less than a distance from the optical layer to the sensor.
A display device, comprising:
- an upper layer having a fingerprint detection region disposed on a top surface of the upper layer,
- wherein the fingerprint detection region receives a light indicating fingerprint information;
- an optical layer disposed below the upper layer and having a plurality of transmission holes through which the light penetrating the upper layer passes;
- a lower layer disposed below the optical layer and on which the light passing through the transmission holes is received and passes through,
- wherein a refractive index of the lower layer is greater than a refractive index of the upper layer;
- and
- a sensor disposed below the lower layer and overlapping the fingerprint detection region,
- wherein the sensor receives the light passing through the lower layer,
- wherein a thickness of the lower layer is greater than a thickness of the upper layer.
A display device, comprising:
- a display module comprising a first non-folding region, a second non-folding region comprising a fingerprint detection region in which fingerprint information is detected, and a folding region disposed between the first non-folding region and the second non-folding region,
- wherein the folding region is foldable about a folding axis;
- a support plate disposed below the display module and in which an opening overlapping the fingerprint detection region is defined;
- a sensor disposed below the support plate and overlapping the opening;
- and
- a protection layer disposed between the display module and the support plate,
- wherein a refractive index of the protection layer is greater than a refractive index of the display module.
