Lenticular projection screen

Claim 2

A lenticular projection screen comprising: a layer of light reflective material, having a plurality of overlapping, curved reflection lenses formed in the surface of said reflective material, each individual reflector having a predetermined number of degrees of arc included in the height and width thereof for selectively directing projected light rays from the screen to predetermined horizontal and vertical viewing areas, thereby reducing scattering losses and increasing the qualiTy of the projected screen image; said reflective lenses being spherical and concave in shape; and a plurality of planar light absorbing members, disposed perpendicular to each of the surfaces of said lenses, bisecting the center of curvatures thereof, and having an aperture provided therein positioned at the focal length of each of said lenses, for allowing selective reflection of projected light rays originating from a predetermined source and absorbing ambient light rays impinging upon the surface of the screen.

Claim 3

The lenticular screen as recited in claim 1 wherein said light absorbing members further comprise a coating of flat, black paint for absorbing reflected light rays which impinge upon the surfaces of said light absorbing members.

Claim 4

A lenticular projection screen comprising: a layer of light reflective material, having a plurality of overlapping, curved reflection lenses formed in the surface of said reflective material, each individual reflector having a predetermined number of degrees of arc included in the height and width thereof for selectively directing projected light rays from the screen to predetermined horizontal and vertical viewing areas, thereby reducing scattering losses and increasing the quality of the projected screen image; said reflective lenses being spherical and concave in shape; a plurality of planar light absorbing members disposed perpendicular to the surface of said individual lenses, and bisecting the center of curvatures thereof, and having a reflective member thereon, positioned on both sides of said planar member at the focal point of said lenses, for selectively reflecting light rays projected from a predetermined source to predetermined viewing areas, and absorbing ambient light rays impinging on the screen during use; said planar members physically disect each of said lenses and are disposed between the halves of said lenses so as to disect the longitudinal center of curvatures thereof; and said planar members are tapered radially outwardly beginning at said reflective members, so as to reduce the non-viewing area present directly in front of each of said lenses along the outer edge of said planar members.

Claim 5

A lenticular projection screen comprising: a layer of light reflective material, having a plurality of overlapping, curved reflection lenses formed in the surface of said reflective material, each individual reflector having a predetermined number of degrees of arc included in the height and width thereof for selectively directing projected light rays from the screen to predetermined horizontal and vertical viewing areas, thereby reducing scattering losses and increasing the quality of the projected screen image; said reflective lenses being spherical and concave in shape; a plurality of planar light absorbing members disposed perpendicular to the surface of said individual lenses, and bisecting the center of curvatures thereof, and having a reflective member thereon, positioned on both sides of said planar member at the focal point of said lenses, for selectively reflecting light rays projected from a predetermined source to predetermined viewing areas, and absorbing ambient light rays impinging on the screen during use; said planar members physically disect each of said lenses and are disposed between the halves of said lenses so as to disect the longitudinal center of curvatures thereof; and said planar members are tapered radially outwardly beginning at said reflective members, so as to reduce the non-viewing area present directly in front of each of said lenses along the outer edge of said planar members.

Claim 6

The lenticular screen as recited in claim 3 wherein said light absorbing members are coated with a flat, black light absorbant material for absorbing light rays impinging upon the surface of said planar members.

Claim 7

The lenticular screen as recited in claim 4 further comprising rotating means rigidly affixed to the lenticular screen for rotating each of said lenses of the screen in an identical, predetermined, radius of rotation, thereby allowing the use of large individual lenses to obtain a high quality projected screen image.

Claim 8

The lenticular screen as recited in claim 5 wherein the screen is spherically-shaped, and wherein the screen describes a spherical rotating motion.

Claim 9

A lenticular projection screen comprising: a layer of light reflective material, having a plurality of overlapping, curved reflection lenses formed in the surface of said reflective material, each individual reflector having a predetermined number of degrees of arc included in the height and width thereof for selectively directing projected light rays from the screen to predetermined horizontal and vertical viewing areas, thereby reducing scattering losses and increasing the quality of the projected screen image; said reflective lenses being spherical and concave in shape; and a plurality of planar light absorbing members, disposed perpendicular to each of the surfaces of said lenses, and having an aperture provided therein positioned at the focal length of each of said lenses, for allowing selective reflection of projected light rays originating from a predetermined source and absorbing ambient light rays impinging upon the surface of the screen.

Claim 10

A lenticular projection screen comprising: a layer of light reflective material, having a plurality of overlapping, curved reflection lenses formed in the surface of said reflective material, each individual reflector having a predetermined number of degrees of arc included in the height and width thereof for selectively directing projected light rays from the screen to predetermined horizontal and vertical viewing areas, thereby reducing scattering losses and increasing the quality of the projected screen image; said reflective lenses being spherical and concave in shape; and a plurality of planar light absorbing members, disposed perpendicular to each of the surfaces of said lenses, and having an aperture provided therein positioned at the focal length of each of said lenses, for allowing selective reflection of projected light rays originating from a predetermined source and absorbing ambient light rays impinging upon the surface of the screen.
