Display device
To provide a display device that gives a viewer a strong stereoscopic effect or sense of depth or a natural stereoscopic effect or sense of depth in a two-dimensional image, a display device including a display portion having a curved surface is provided. The display portion may be bent in a horizontal direction or a vertical direction. Alternatively, the display portion may have a convex surface or a concave surface on a display surface side. The display device may include a frame portion. A display device including a frame portion and a display portion which has a display surface on a frame portion side, is located so as to be apart from the frame portion with a distance therebetween, and has a curved surface, in which the display portion overlaps with an opening of the frame portion, and an end portion of the display portion overlaps with the frame portion, is provided.
1. A display device comprising:
a display portion comprising a curved display surface; and
a frame portion comprising an opening, provided in front of the display surface with a distance therebetween,
wherein the opening of the frame portion overlaps with the display surface,
wherein the frame portion overlaps with an end portion of the display portion, and
wherein the frame portion is configured to be curved independently of the curvature of the display portion.
2. The display device according to claim 1 , wherein a degree and a direction of a curvature of the display surface are configured to be changed.
3. The display device according to claim 1 , wherein each of the display surface and the frame portion can be curved convexly or concavely in a horizontal or vertical direction.
4. The display device according to claim 1 ,
wherein a curved line is provided at a corner of an inner frame of the frame portion.
5. The display device according to claim 4 , wherein the curvature of the curved line of the corner of the inner frame is larger than curvature of a corner of the display portion.
6. The display device according to claim 1 , wherein a size of the opening of the frame portion is configured to be changed.
7. The display device according to claim 1 , wherein the frame portion can be attached to and detached from the display device.
8. The display device according to claim 1 , wherein the frame portion has a light-blocking property.
9. A display device comprising:
a display portion configured to be curved;
an arithmetic processing portion configured to be supplied with data and generate a control signal by analyzing the data;
a drive control portion configured to be supplied with the control signal and change a degree and a direction of a curvature of the display portion; and
a frame portion comprising an opening,
wherein the frame portion is configured to be curved, and
wherein a degree and a direction of a curvature of the frame portion can be changed independently of the curvature of the display portion.
10. The display device according to claim 9 ,
wherein the frame portion faces a display surface of the display portion with a distance therebetween,
wherein the opening of the frame portion overlaps with the display surface, and
wherein the frame portion overlaps with an end portion of the display portion.
11. The display device according to claim 9 , wherein each of the display portion and the frame portion can be curved convexly or concavely in a horizontal or vertical direction.
12. The display device according to claim 9 , wherein the data includes image data and audio data.
13. A display device comprising:
a light-transmitting layer comprising a viewing surface and a curved surface opposite to each other;
a display portion comprising a curved display surface along and in contact with the curved surface of the light-transmitting layer; and
a frame portion comprising an opening, provided in front of the viewing surface,
wherein a refractive index of the light-transmitting layer is higher than a refractive index of the air,
wherein the opening of the frame portion overlaps with the display surface with the light-transmitting layer therebetween,
wherein the frame portion overlaps with an end portion of the display portion with the light-transmitting layer therebetween, and
wherein a thickness at a center of the light-transmitting layer is different from a thickness near an edge of the light-transmitting layer.
14. The display device according to claim 13 , wherein the viewing surface is curved.
15. The display device according to claim 13 , wherein the frame portion is in contact with the viewing surface and the end portion of the display portion.
16. The display device according to claim 13 , wherein the display portion comprises a plurality of light emitting elements which emit light toward the viewing surface.
17. The display device according to claim 13 , wherein the frame portion has a light-blocking property.
