Abstract

A display unit of the present disclosure includes: a first plate-like member including a display device; a second plate-like member including a drive circuit, the drive circuit configured to control the display device; and one or two or more wiring sections having flexibility, the wiring sections configured to connect the first plate-like member and the second plate-like member to each other, in which a curvature of the second plate-like member is larger than 0 and equal to or smaller than a curvature of the first plate-like member.

Claims (33)

1. An organic EL display unit comprising:

a first plate-like member including a display device;

a second plate-like member comprising circuitry for display device control; and

one or more flexible sections coupling the first plate-like member and the second plate-like member to each other,

wherein both before and during driving of the display unit a curvature, indicating amount of deviation from a straight line, of the first plate-like member is larger than 0 and the curvature of the first plate-like member is larger than a curvature, indicating amount of deviation from a straight line, of the second plate-like member,

wherein both the first plate-like member and the second plate-like member are curved in the same direction, and

wherein the curvature of the first plate-like member during driving of the display unit is changed by a first amount relative to the curvature of the first plate-like member before driving of the display unit, the curvature of the second plate-like member during driving of the display unit is changed by a second amount relative to the curvature of the second plate-like member before driving of the display unit, and the first amount is different from the second amount.

2. The organic EL display unit according to claim 1 , wherein the one or more flexible sections comprise two or more wiring sections.

3. The organic EL display unit according to claim 1 , wherein a thermal expansion coefficient of the first plate-like member is smaller than that of the second plate-like member.

4. The organic EL display unit according to claim 1 , further comprising at least one holding section attached to a supporting member, which is attached to one side of the first plate-like member, wherein the at least one holding section comprises a locking section at both ends of the holding section for supporting the second plate-like member.

5. The organic EL display unit according to claim 4 , wherein the second plate-like member is disposed on a back surface side of the first plate-like member.

6. The organic EL display unit according to claim 4 , wherein the width of the interior gap of the at least one locking section is larger than a thickness of the second plate-like member.

7. The organic EL display unit according to claim 2 , wherein an IC chip is provided on each of the wiring sections.

8. The organic EL display unit according to claim 7 , wherein the IC chip on each of the wiring sections is in contact with a heat dissipation member.

9. The organic EL display unit according to claim 8 , wherein a curvature of the heat dissipation member is equal to or larger than 0 and equal to or smaller than that of the first plate-like member.

10. The display unit according to claim 1 , wherein second plate-like member is flat prior to attachment to the first plate-like member.

11. A display unit comprising:

a first plate-like member including a display device;

a second plate-like member comprising circuitry for display device control; and

one or more flexible sections coupling the first plate-like member and the second plate-like member to each other,

wherein both before and during driving of the display unit a curvature, indicating amount of deviation from a straight line, of the first plate-like member is larger than 0 and the curvature of the first plate-like member is larger than a curvature, indicating amount of deviation from a straight line, of the second plate-like member,

wherein both the first plate-like member and the second plate-like member are curved in the same direction, and

wherein the curvature of the first plate-like member during driving of the display unit is changed by a first amount relative to the curvature of the first plate-like member before driving of the display unit, the curvature of the second plate-like member during driving of the display unit is changed by a second amount relative to the curvature of the second plate-like member before driving of the display unit, and the first amount is different from the second amount.

12. The display unit according to claim 11 , wherein the one or more flexible sections comprise two or more wiring sections.

13. The display unit according to claim 12 , wherein a thermal expansion coefficient of the first plate-like member is smaller than that of the second plate-like member.

14. The display unit according to claim 11 , further comprising at least one holding section attached to a supporting member, which is attached to one side of the first plate-like member, wherein the at least one holding section comprises a locking section at both ends of the holding section for supporting the second plate-like member.

15. The display unit according to claim 14 , wherein the second plate-like member is disposed on a back surface side of the first plate-like member.

16. The display unit according to claim 12 , wherein the two or more wiring sections each include two parallel sections with respect to the first plate-like member and a vertical section connecting these parallel sections to each other.

17. The display unit according to claim 14 , wherein the width of the interior gap of the at least one locking section is larger than a thickness of the second plate-like member.

18. The display unit according to claim 12 , wherein an IC chip is provided on each of the wiring sections.

19. The display unit according to claim 18 , wherein the IC chip on each of the wiring sections is in contact with a heat dissipation member.

20. The display unit according to claim 19 , wherein a curvature of the heat dissipation member is equal to or larger than 0 and equal to or smaller than that of the first plate-like member.

21. The display unit according to claim 11 , wherein second plate-like member is flat prior to attachment to the first plate-like member.
