Abstract
There is provided an optical substrate. The optical substrate includes at least one surface, The at least one surface includes at least one optical structure having a shape and dimensions, wherein the shape and dimensions of each optical structure represents in part a modulation of a corresponding idealized structure. The shape and dimensions of each of the at least one optical structure are determined in part by at least one randomly generated component of modulation wherein the modulation of each of the at least one optical structure is limited by a neighboring optical structure comprised by the surface.
Claims6
An optical substrate comprising:
- at least one surface, said at least one surface comprising at least one optical structure having a shape and dimensions, wherein the shape and dimensions of each optical structure represents in part a modulation of a corresponding idealized structure, and wherein said shape and dimensions of each of said at least one optical structure is determined in part by at least one randomly generated component of modulation wherein the modulation of each of said at least one optical structure is limited by a neighboring optical structure comprised by the surface, wherein said at least one optical structure represents an idealized prismatic structure following a surface path modulated by a sinusoidal function.
A backlight display device comprising:
- a light source for generating light;
- a light guide for guiding the light therealong including a reflective surface fo reflecting the light out of the light guide;
- and
- an optical film comprising:
- at least one surface, said at least one surface comprising at least one optical structure having a shape and dimensions, wherein the shape and dimensions of each optical structure represents in part a modulation of a corresponding idealized structure, and wherein said shape and dimensions of each of said at least one optical structure is determined in part by at least one randomly generated component of modulation wherein the modulation of each of said at least one optical structure is limited by a neighboring optical structure comprised by the surface, wherein said at least one optical structure represents an idealized prismatic structure following a surface path modulated by a sinusoidal function.
