Display device, display unit, and display system
Provided is a display device or a display system capable of displaying images along a curved surface, a display device or a display system capable of displaying images seamlessly in the form of a ring, or a display device or a display system that is suitable for increasing in size. The display device includes a display panel. The display panel includes a first part and a second part and is flexible. The first part can display images. The second part can transmit visible light. The display panel is curved so that the second part and the first part overlap with each other.
1. A display device comprising:
a display panel; and
a protective substrate,
wherein the display panel comprises a display region and a light-transmitting region at one end of the display panel,
wherein the light-transmitting region is adjacent to the display region,
wherein the display panel further comprises a light-blocking region adjacent to the display region,
wherein the light-blocking region comprises a flexible printed circuit and a driver circuit,
wherein the display panel is flexible,
wherein the display panel is curved to form a ring so that the light-transmitting region overlaps with a display surface side of the display region,
wherein the protective substrate is provided on a surface opposite to the display surface side of the display panel,
wherein each of the light-transmitting region and a part of the display region extend beyond the protective substrate,
wherein the protective substrate comprises an opening to pass the flexible printed circuit therethrough,
wherein the display device is in the form of a cylinder, and
wherein the display surface side of the display region faces inward.
2. The display device according to claim 1 , wherein a ring-shaped seamless image is displayed on the display region along a curved surface of the cylinder.
3. The display device according to claim 1 , wherein the display region comprises an organic electroluminescent element.
4. The display device according to claim 1 , wherein the light-transmitting region is provided along a first long side and a first short side adjacent to the first long side of the display panel.
5. A display device comprising:
a display panel; and
a protective substrate,
wherein the display panel comprises a display region and a light-transmitting region at one end of the display panel,
wherein the light-transmitting region is adjacent to the display region,
wherein the display panel is flexible,
wherein the display panel is curved to form a ring so that the light-transmitting region overlaps with a display surface side of the display region,
wherein the protective substrate is provided on a surface opposite to the display surface side of the display panel,
wherein each of the light-transmitting region and a part of the display region extend beyond the protective substrate,
wherein the display device is in the form of a cylinder, and
wherein the display surface side of the display region faces inward.
6. The display device according to claim 5 , wherein a ring-shaped seamless image is displayed on the display region along a curved surface of the cylinder.
7. The display device according to claim 5 , wherein the display region comprises an organic electroluminescent element.
8. The display device according to claim 5 , wherein the light-transmitting region is provided along a first long side and a first short side adjacent to the first long side of the display panel.
