Abstract:
1. Shutter glasses for a display apparatus, the shutter glasses comprising: a shutter-glasses communication unit configured to receive a first sync signal from the display apparatus displaying a three-dimensional (3D) image; and a shutter-glasses controller configured to convert the first sync signal into a second sync signal and configured to generate a driving signal for a left-eye lens unit and a right-eye lens unit of the shutter glasses based on the second sync signal, wherein the first sync signal is generated in the display apparatus by omitting at least one sync pulse in the second sync signal cording to a predetermined pattern so that a frequency of the first sync signal is reduced while being transmitted from the display apparatus to the shutter glasses, and the second sync signal comprises a plurality of sync pulses and is generated corresponding to the 3D image, and wherein the shutter-glasses controller converts the first sync signal into the second sync signal by restoring the omitted sync pulse from the first sync signal according to the predetermined pattern.
