Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
86 words
A novel screen assembly comprised of: a frame member; and a plurality of optical fibers parallelly-disposed within said frame member and in closed packed relationship and bonded to each other, said optical fibers being of a length of from 0.5 mm to 16 inches thereby forming front and rear surface portions of said frame member, said front surface portion being formed in parallelled relationship to said rear surface portions, said front and rear surface portions having polished surfaces, said screen assembly receiving and projecting light images.
Claim 2
Dependent Claim
86 words
A novel screen assembly comprised of: a frame member; and a plurality of optical fibers parallelly-disposed within said frame member and in closed packed relationship and bonded to each other, said optical fibers being of a length of from 0.5 mm to 16 inches thereby forming front and rear surface portions of said frame member, said front surface portion being formed in parallelled relationship to said rear surface portions, said front and rear surface portions having polished surfaces, said screen assembly receiving and projecting light images.
Claim 3
Dependent Claim
24 words
