Abstract
A lenticular system for autostereoscopic display devices in which a transparent polymeric lenticular array is embedded between two glass sheets and the gap between the polymeric lenticular array and the outer cover is filled with a transparent polymeric filling having a refractive index different than the refractive index of the polymeric lenticular array to reduce glare.
Claims20
A lenticular system for autostereoscopic display devices comprising:
- a. a polymeric sheet formed of a first transparent polymer having a first refractive index and formed in a lenticular array, wherein the thusly formed polymeric lenticular array includes a plurality of longitudinally extending projections arranged in substantially parallel rows on the surface thereof;
- b. a glass substrate and a glass cover;
- c. the polymeric lenticular array being sandwiched between the glass substrate and the glass cover, there being a gap between the projections on the polymeric lenticular array and the cover;
- d. the gap between the glass cover and the projections on the polymeric lenticular array being filled with a filling layer formed of a second transparent polymer having second refractive index;
- and
- e. the second refractive index being so related to the first refractive index of the polymeric lenticular array that light reflected at an interface between the polymeric lenticular array and the polymeric filling will not exceed 4% of a total light incident at the interface.

An autostereoscopic display device comprising
- a. a pixelated image source and a lenticular system onto which the pixilated image is displayed;
- b. the lenticular system comprising:
- i. a polymeric sheet formed of a first transparent polymer having a first refractive index and formed in a lenticular array, wherein the thusly formed polymeric lenticular array includes a plurality of longitudinally extending projections arranged in substantially parallel rows on the surface thereof;
- ii. a glass substrate and a glass cover;
- iii. the polymeric lenticular array being sandwiched between the glass substrate and the glass cover, there being a gap between the projections on the polymeric lenticular array and the cover;
- iv. the gap between the glass cover and the projections on the polymeric lenticular array being filled with a filling layer formed of a second transparent polymer having second refractive index;
- and
- v. the second refractive index being so related to the first refractive index of the polymeric lenticular array that light reflected at an interface between the polymeric lenticular array sheet and the polymeric filling will not exceed 4% of a total light incident at the interface.
