Abstract

Three-dimensional (3D) eyeglasses, a charging cradle, a 3D display apparatus, and a system for charging 3D eyeglasses wirelessly are provided. A pair of 3D eyeglasses which operates in association with the 3D display apparatus includes a wireless charging unit which generates electricity using a signal wirelessly received from an external apparatus, and a power supply unit which supplies power to the 3D eyeglasses using the electricity charged by the wireless charging unit.

Claims

1. A pair of three-dimensional (3D) eyeglasses which operates in association with a 3D display apparatus, the pair of 3D eyeglasses comprising:

a wireless charging unit which generates electricity using a signal wirelessly received from an external apparatus; and

a power supply unit which supplies power to the 3D eyeglasses using electricity generated by the wireless charging unit.

2. The pair of 3D eyeglasses as claimed in claim 1, wherein the wireless charging unit receives a resonance wave and generates the electricity based on the resonance wave.

3. The pair of 3D eyeglasses as claimed in claim 2, wherein the wireless charging unit comprises:

a reception resonator which wirelessly receives the resonance wave from the external apparatus;

a rectifier which rectifies the received resonance wave to a direct current (DC);

a voltage adjuster which adjusts a voltage of the rectified DC to be maintained at a constant level; and

a charging unit which supplies the DC adjusted by the voltage adjuster to the power supply unit.

4. The pair of 3D eyeglasses as claimed in claim 3, wherein the external apparatus is the 3D display apparatus and the reception resonator has a resonance frequency equal to a resonance frequency of a transmission resonator included in the 3D display apparatus.

5. The pair of 3D eyeglasses as claimed in claim 3, wherein the reception resonator is located in a rim of the pair of 3D eyeglasses.

6. The pair of 3D eyeglasses as claimed in claim 3, wherein the reception resonator is located in a temple of the pair of 3D eyeglasses.

7. The pair of 3D eyeglasses as claimed in claim 1, wherein the external apparatus is the 3D display apparatus.

8. The pair of 3D eyeglasses as claimed in claim 1, wherein the wireless charging unit charges the pair 3D eyeglasses wirelessly using a non-contact charging method.

9. The pair of 3D eyeglasses as claimed in claim 8, wherein the wireless charging unit comprises:

a secondary coil which is magnetically coupleable to a the primary coil of the external apparatus, thus receiving an induced electromotive force;

a rectifier which rectifies the induced electromotive force to a direct current (DC);

a voltage adjuster which adjusts a voltage of the rectified DC to be maintained at a constant level; and

a charging unit which supplies the DC adjusted by the voltage adjuster to the power supply unit.

10. The pair of 3D eyeglasses as claimed in claim 3, wherein the charging unit comprises a super capacitor.

11. A charging cradle for charging a pair of 3D eyeglasses, the charging cradle comprising:

a power supply unit which supplies power; and

a wireless transmitter which uses the supplied power and wirelessly transmits energy to the pair of 3D eyeglasses.

12. The charging cradle as claimed in claim 11, wherein the charging cradle is mountable to a 3D display apparatus.

13. The charging cradle as claimed in claim 11, wherein the charging cradle comprises a plurality of holders on which a plurality of pairs of 3D eyeglasses are hangable.

14. The charging cradle as claimed in claim 11, wherein the charging cradle comprises a plurality of containers within each of which a pair of 3D eyeglasses may be contained.

15. The charging cradle as claimed in claim 11, wherein the charging cradle comprises a container within which a plurality of pairs of 3D eyeglasses are containable.

16. The charging cradle as claimed in claim 11, wherein the charging cradle comprises a surface on which a plurality of pairs of 3D eyeglasses are supportable.

17. A 3D display apparatus which operates in association with a pair of 3D eyeglasses, the 3D display apparatus comprising:

a power supply unit which supplies power; and

a wireless transmitter which uses the supplied power and wirelessly transmits energy to the pair of 3D eyeglasses.

18. A system for charging a pair of three-dimensional (3D) eyeglasses wirelessly, the system comprising:
