We would like someone to modify a pair of LCD shutter glasses (such as those used with 3D TVs) to take a digital control signal (3V) to set and hold the state of both lenses of the glasses to be either clear or fully opaque. My understanding is that the best way to do this is to drive the LCD using a pair of square waves (with no DC component) that are either in phase or out of phase, to prevent damage to the LCD electrodes. One potential solution to the design of the driving circuit is here: [login to view URL](Rev%203).pdf (see Fig. 2). However, because we are using a low-frequency magnetic-field based motion tracking system in conjunction with these glasses, we also need this driver circuit and the wiring to the lenses to not emit a strong magnetic field so as to minimize its interaction with the motion tracker. Hence a bit of thoughtful circuit and wiring design is needed in order to drive the LCDs to be fully clear or opaque (i.e., create a voltage drop of sufficient magnitude to make the lenses transition states fully) while minimizing the magnetic field emitted due to the pair of AC square waves.
