Abstract
The present invention discloses a 2D/3D switchable liquid crystal lens assembly. The liquid crystal lens assembly from an emitting surface to an incident surface sequentially includes a plurality of adjacently arranged elongated convex lenses, a first transparent substrate, a second transparent substrate, a plurality of electrodes disposed on the second transparent substrate, and a liquid crystal layer sandwiched between the first and second transparent substrates. The plurality of electrodes are used for controlling an alignment of liquid crystal molecules inside the liquid crystal layer so as to adjust a refractive index of the liquid crystal molecules inside the liquid crystal layer corresponding to at least one pixel. The refractive index progressively increase or progressively decrease from a center toward both sides to control a propagation direction of incident light and guide the passed incident light to one of the convex lenses.
