Abstract:
This disclosure provides a technique for controlling the slew rate and number of transition segments used to move the LC drive voltage level from one voltage to another. In one embodiment, a method of controlling a polarization modulator in a polarization-based stereoscopic display device may comprise providing digital signals to each of a plurality of drive circuits to generate a drive voltage from each drive circuit, where the drive voltages drive the polarization modulator. Such an exemplary method may also include determining a time sequential list of transition specifications configured to provide discrete transitions in one or more of the drive voltages. Then, in such methods, the digital signals provided to each of the one or more drive circuits receiving a transition may be adjusted, in accordance with the time sequential list, thereby altering their drive voltages based on the transition specifications.
