Attorney, Agent or Firm: Parsons; Eugene A.

A switchable lens/diffuser including an optical component constructed to form an optical image in cooperation with light directed thereon and a layer of polymer dispersed liquid crystal material having a clear state and a diffusing state, the layer of material being positioned in conjunction with the optical component so that the optical component forms an optical image when the layer of polymer dispersed liquid crystal material is in the clear state and the layer of polymer dispersed liquid crystal material serves as a diffusing screen to form an image in cooperation with the light directed thereon in the diffusing state.

DETAILED DESCRIPTION The above problems and others are at least partially solved and the above purposes and others are realized in a switchable lens/diffuser including an optical component constructed to form an optical image in cooperation with light directed thereon and a layer of polymer dispersed liquid crystal material having a clear state and a diffusing state, the layer of material being positioned in conjunction with the optical component so that the optical component forms an optical image when the layer of polymer dispersed liquid crystal material is in the clear state and the layer of polymer dispersed liquid crystal material serves as a diffusing screen to form an image in cooperation with the light directed thereon in the diffusing state.
