Patent Images
1. A tunable electro-optic lens device comprising:
- a first transparent substrate comprising a transparent conductive first electrode layer operatively connected thereto, the first electrode layer being patterned and comprising a first plurality of substantially concentric ring electrodes that form a first resistive divider network;
a second transparent substrate comprising a transparent conductive second electrode layer operatively connected thereto; and
an electro-active liquid crystal material layer located between the first transparent substrate and the second transparent substrate;
wherein;
a first ring electrode from the first plurality of ring electrodes is electrically connected to a substantially adjacent ring electrode from the first plurality of ring electrodes by a substantially co-planar first resistive arc that electrically spans a gap overlap zone defined by a spiralesque insulating gap that substantially separates the first ring electrode from the adjacent ring electrode;
the spiralesque insulating gap extends more than one revolution, and less than two revolutions, substantially around a rotational axis of the at least one ring electrode to define the gap overlap zone;
the gap overlap zone defines a gap overlap zone arc length and a gap overlap zone width;
the gap overlap zone arc length defines a length of the first resistive arc and the gap overlap zone width defines a width of the first resistive arc;
the first resistive arc defines a resistive path through the gap overlap zone; and
a first sub-plurality of continuous ring electrodes from the first plurality of continuous ring electrodes is connected to a first input connection, the first input connection terminating an input line.
