Display apparatus, shutter glasses, display method, and method for operating glasses apparatus

A display apparatus comprising:

• a signal processor which configures an image frame according to a display mode;
• a display configured to output the image frame configured by the signal processor;
• a pattern retarder configured to polarize the output image frame differently in each region;
• a communicator configured to transmit at least one from among a sync signal and an audio signal to a glasses apparatus, the glasses apparatus allowing a user to view the image frame polarized differently in each region;
• and
• a controller configured to control to transmit at least one from among a sync signal and the audio signal to the glasses apparatus according to the display mode,
• wherein the display mode is one from among a 2D single view mode in which a single 2D content is displayed, a 2D multi view mode in which a plurality of 2D contents are displayed, a 3D single view mode in which a single 3D content is displayed, and a 3D multi view mode in which a plurality of 3D contents are displayed.

A display method comprising:

• configuring an image frame according to a display mode;
• outputting the configured image frame;
• polarizing the output image frame differently in each region;
• and
• transmitting at least one from among a sync signal and an audio signal to a glasses apparatus according to the display mode, the glasses apparatus allowing a user to view the image frame polarized differently in each region,
• wherein the display mode is one from among a 2D single view mode in which a single 2D content is displayed, a 2D multi view mode in which a plurality of 2D contents are displayed, a 3D single view mode in which a single 3D content is displayed, and a 3D multi view mode in which a plurality of 3D contents are displayed.

A system comprising:

• at least one glasses apparatus;
• and
• a display apparatus,
• wherein at least one of the at least one glasses apparatus comprises:
• a first retarder configured to delay phases of a first image and a second image which are output from the display apparatus;
• a second retarder configured to delay the phases of the first image and the second image in a direction different from that of the first retarder;
• a first shutter glass and a second shutter glass configured to change polarization properties of the first image optical axis and the second image optical axis, which are rotated;
• and
• a controller configured to control to selectively supply the power to the first shutter glass and the second shutter glass so that a user selectively views the first image and the second image, and
• wherein the display apparatus comprises:
• a signal processor which configures an image frame according to a display mode;
• a display configured to output the image frame configured by the signal processor;
• a pattern retarder configured to polarize the output image frame differently in each region;
• a communicator configured to transmit at least one from among a sync signal and an audio signal to the at least one glasses apparatus, the at least one glasses apparatus configured to allow a user to view the image frame polarized differently in each region;
• and
• a controller configured to control to transmit at least one from among a sync signal and the audio signal to the at least one glasses apparatus according to the display mode.
