Abstract
A driving circuit system for a stereoscopic image display device including a central controlling unit outputting control signals and selection signals according to command signals of an external device, a signal-generating unit outputting driving signals according to the control signals, an output signal-controlling unit receiving the driving signals and outputting the driving signals selected according to the selection signals to a light controlling unit of the stereoscopic image display device, and a connector unit connecting the external device and the light controlling unit.
Claims29
A driving circuit system for a stereoscopic image display device, comprising:
- a central controlling unit coupled with an external device, outputting control signals and selection signals according to command signals from the external device;
- a signal-generating unit coupled to the central controlling unit, outputting driving signals according to the control signals from the central controlling unit;
- an output signal-controlling unit coupled with the central controlling unit and signal-generating unit, receiving the selection signals and the driving signals and outputting the driving signals selected based on the selection signals to a light controlling unit of the stereoscopic image display device;
- and
- a connector unit coupling the external device with the light controlling unit.
A driving method of a driving circuit system for a stereoscopic image display device, comprising:
- outputting control signals and selection signals from a central controlling unit according to command signals received from an external device;
- outputting driving signals from a signal-generating unit to an output signal-controlling unit based on the control signals;
- and
- selectively outputting the driving signals from the output signal-controlling unit to a light controlling unit of the stereoscopic image display device based on the selection signals from the central controlling unit.
A stereoscopic image display device, comprising:
- a light controlling unit comprising a plurality of regions wherein the plurality of regions is further divided into a plurality of sub-regions;
- an interface circuit that transmits driving signals to the light controlling unit that represent the voltage supplied to each of the plurality of sub-regions, wherein each of the plurality of regions has at least one first sub-region receiving a common voltage and at least one second sub-region receiving a voltage that alternates between two voltage values;
- and
- a display coupled with the light controlling unit displaying an image wherein light is transmitted through each of the plurality of at least one first sub-regions and light is blocked by each of the plurality of at least one second sub-regions.
