Abstract

According to one embodiment, an image display apparatus includes a connection module, a power transmitting module, a receiving module and a display module. The connection module is configured to be electrically connected to 3D image viewing glasses. The power transmitting module is configured to transmit power to the 3D image viewing glasses via the connection module. The receiving module is configured to receive information relating to a charging amount of the 3D image viewing glasses. The display module is configured to display an image representing the charging amount of the 3D image viewing glasses based on the information relating to the charging amount.

Claims

1. An image display system comprising:

a digital television receiver configured to display on a screen images in a format configured to viewed in 3D; and

rechargeable 3D image viewing glasses configured to allow a user to view in 3D the images displayed on the screen in the 3D-viewable format, the 3D image viewing glasses comprising

a rechargeable battery, and

a charging circuit configured to detect a charge amount of the battery and transmit battery residual-capacity information relating to the detected charge amount to the digital television receiver, and

the digital television receiver being configured to recharge the 3D image viewing glasses and comprising

a power transmitter configured to allow power to be transmitted to the rechargeable battery of the 3D image viewing glasses,

a receiving processor configured to receive the battery residual-capacity information from the battery processor of the 3D image viewing glasses,

a display processor configured to display on the screen an image representing the charge amount of the 3D image viewing glasses based on the received battery residual-capacity information, and

a power controller configured to switch between a first state, configured to allow the power transmitter to transmit power to the rechargeable battery, and a second state, configured to allow for display of the 3D-viewable images.

2. The image display system of claim 1, further comprising an indicator comprising a light-emitting diode configured to indicate a charge state of the 3D image viewing glasses.

3. An image display apparatus comprising:

a power transmitter configured to allow power to be transmitted to rechargeable 3D image viewing glasses, thereby allowing the rechargeable 3D image viewing glasses to be recharged;

a receiving module configured to receive information relating to a charge amount of the 3D image viewing glasses; and

a display module configured to display an image representing the charge amount of the 3D image viewing glasses based on the information relating to the charge amount.

4. The apparatus of claim 3, further comprising:

an instruction transmitting module configured to transmit, to the 3D image viewing glasses, an instruction signal to transmit information relating to the charge amount of the 3D image viewing glasses.

5. The apparatus of claim 3, further comprising:

a power controller configured to switch between a power-on state and a standby state,

wherein the power transmitting module is configured to transmit the power in the standby state.

6. The apparatus of claim 3, wherein the display module is configured to display a charging ratio defining a ratio of a current charge amount to a maximum charge amount of the 3D image viewing glasses based on the information relating to the charge amount.

7. The apparatus of claim 3, wherein the display module is configured to display a usable time of the 3D image viewing glasses based on the information relating to the charge amount.

8. The apparatus of claim 3, wherein the display module is configured to display a message indicating that charging of the 3D image viewing glasses has been completed based on the information relating to the charge amount.

9. The apparatus of claim 5, further comprising:

an indicator configured to display a visual indication based on the information relating to the charge amount,

wherein the indicator is configured to display the visual indication based on the information relating to the charge amount when the apparatus is in the standby state.

10. The apparatus of claim 9, wherein the indicator comprises a light-emitting diode.

11. A display method performed in an image display apparatus comprising:

electrically connecting to 3D image viewing glasses;

transmitting power to the connected 3D image viewing glasses;

receiving information relating to a charge amount of the 3D image viewing glasses; and

displaying an image representing the charge amount of the 3D image viewing glasses based on the information relating to the charge amount.

12. The method of claim 11, further comprising determining whether the charge amount of the 3D image viewing glasses has reached a predetermined maximum charge value, and

if the charge amount has reached the predetermined maximum charge value, setting the image to represent that charging of the 3D image viewing glasses is complete, and

if the charge amount has not reached the predetermined maximum charge value, setting the image to represent an amount of time that the 3D image viewing glasses can be used for viewing 3D images displayed on the image display apparatus.
