Glasses apparatus and power supply apparatus
First Claim
1. A glasses apparatus interlocking with a 3D display device, the glasses apparatus comprising:
- a shutter glasses;
a synchronous signal receiver which receives a synchronous signal from the 3D display device;
a shutter glasses driver which drives the shutter glasses;
a DC/DC converter which converts a DC voltage provided from a battery; and
a controller which controls the DC/DC converter to apply the converted DC voltage to the shutter glasses driver through supplying of a PWM signal to the DC/DC converter, and controlling the shutter glasses driver, which is driven by the applied DC voltage, to turn on/off the shutter glasses according to the synchronous signal,wherein the controller comprises;
a PWM signal generator which generates and provides the PWM signal to the DC/DC converter; and
a comparator which receives a feedback of the DC voltage output from the DC/DC converter and compares the DC voltage with a preset voltage level,wherein the comparator outputs a LOW signal in response to the level of the output DC voltage of the DC/DC converter being equal to or higher than a first preset level, and outputs a HIGH signal in response to the level of the output DC voltage of the DC/DC converter being equal to or lower than a second preset level.
