Patent ID: 7489311

Claim:
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; a connector unit coupling the external device with the light controlling unit, and wherein the signal-generating unit includes at least one regulator having a variable resistance for over-driving liquid crystal molecules of the light controlling unit, wherein the light controlling unit includes a plurality of sub-region groups, each of which includes first, second, third and fourth sub-regions, wherein the first sub-region functions as a slit and simultaneously the second, third and fourth sub-regions function as barriers, and then the third sub-region operates as a slit and simultaneously the first, second and fourth sub-regions operate as barriers at a same time.
