Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
139 words
An image display panel comprising a plurality of multifilament type plastic optical fibers laminated and arranged in a 1/1 positional relationship between two end faces, one end face being an image incident face and the other end face being an image-emitting face, each multifilament type plastic optical fiber comprising 100 to 10000 light-transmitting islands having a diameter of 5 to 200 µ, which are arranged regularly in the sea, wherein, on the image-incident end face, the end faces of the multifilament type optical fibers are laminated closely without any substantial spaces therebetween and are arranged orthogonally to the optical fiber axis, and on the image-emitting end face, the end faces of the multifilament type optical fibers are laminated with spaces formed between the laminated end faces and are inclined to the optical fiber axis to emit a magnified image.
Claim 2
Dependent Claim
139 words
An image display panel comprising a plurality of multifilament type plastic optical fibers laminated and arranged in a 1/1 positional relationship between two end faces, one end face being an image incident face and the other end face being an image-emitting face, each multifilament type plastic optical fiber comprising 100 to 10000 light-transmitting islands having a diameter of 5 to 200 µ, which are arranged regularly in the sea, wherein, on the image-incident end face, the end faces of the multifilament type optical fibers are laminated closely without any substantial spaces therebetween and are arranged orthogonally to the optical fiber axis, and on the image-emitting end face, the end faces of the multifilament type optical fibers are laminated with spaces formed between the laminated end faces and are inclined to the optical fiber axis to emit a magnified image.
Claim 3
Dependent Claim
24 words
An image display panel as set forth in claim 1, wherein the multifilament type optical fibers are arranged in the form of a ribbon.
Claim 4
Dependent Claim
39 words
An image display panel as set forth in claim 1, wherein in each multifilament type optical fiber, the total cross-sectional area of the cores constituting the islands is at least 50% of the sectional area of the optical fiber.
Claim 5
Dependent Claim
22 words
An image display panel as set forth in claim 1, wherein each multifilament type optical fiber has a substantially rectangular cross-sectional shape.
Claim 6
Dependent Claim
27 words
An image display panel as set forth in claim 4, wherein one side of the substantially rectangular cross-sectional shape has a length of 0.3 to 3 mm.
Claim 7
Dependent Claim
28 words
An image display panel as set forth in claim 1, wherein the inclination angle of the image-emitting end face to the optical fiber axis is 8 to 10°.
