<P>PROBLEM TO BE SOLVED: To minimize an error with respect to a sync signal in the process of transmitting the sync signal from a display apparatus to shutter glasses. <P>SOLUTION: Shutter glasses for a display apparatus include a shutter-glasses communication unit which receives a first sync signal from the display apparatus displaying a three-dimensional (3D) image; and a shutter-glasses controller which generates an ON/OFF driving signal for a left-eye lens unit and a right-eye lens unit of the shutter glasses, based on the first sync signal, the first sync signal including a pattern, based on which at least one or more sync pulses are periodically eliminated in a second sync signal, used in displaying the 3D image according to a frame driving frequency of the 3D image. The shutter-glasses controller predicts and generates an ON/OFF driving signal in a section corresponding to the eliminated sync pulse according to a time period of the first sync signal. Thus, error with respect to a sync signal can be minimized in the process of transmitting the sync signal. <P>COPYRIGHT: (C)2011,JPO&INPIT |
