Patent ID: 8237890

Claim:
A three-dimensional (3D) grid controllable liquid crystal lens, comprising: a first substrate; a plurality of first active device arrays disposed on the first substrate, each of the first active device arrays comprising a thin film transistor, a storage capacitor, and a transparent electrode electrically connected to the thin film transistor; a first insulating layer disposed above the first active device arrays; a plurality of first spacers disposed on the first substrate and supporting the first insulating layer, so as to form a first containing space between the first insulating layer and the first active device arrays; a plurality of second active device arrays disposed on the first insulating layer, each of the second active device arrays comprising a thin film transistor, a storage capacitor, and a transparent electrode electrically connected to the thin film transistor; a second insulating layer disposed above the second active device arrays; a plurality of second spacers disposed on the first insulating layer and supporting the second insulating layer, so as to form a second containing space between the second insulating layer and the second active device arrays; a plurality of third active device arrays disposed on the second insulating layer, each of the third active device arrays comprising a thin film transistor, a storage capacitor, and a transparent electrode electrically connected to the thin film transistor; a second substrate comprising a common electrode disposed thereon and arranged opposite to the first substrate, and the common electrode is located between the second substrate and the third active device arrays; a plurality of third spacers disposed on the second insulating layer and supporting the second substrate, so as to form a third containing space between the second substrate and the third active device arrays; and a plurality of liquid crystal layers respectively disposed in the first containing space, the second containing space, and the third containing space.
