1. An illuminator for a display comprising:
- a light guide plate to substantially cover a viewable portion of the display;
a thin-film light-emitting source; and
an optical component comprising a first narrow portion, a second wide portion and a third narrow portion, the second wide portion interposed between the first narrow portion and the third narrow portion, said first narrow portion, said second wide portion, and said third narrow portions being curved, said light-emitting source having one dimension that is substantially the same as the thickness of the light guide plate,wherein the light-emitting source is disposed with respect to the first narrow portion such that the optical component admits light from the light-emitting source which is directed into the light guide plate via the optical component to provide light for the viewable portion of the display.

23. An illuminator for a display comprising:
-
a means for guiding light substantially covering a viewable portion of the display; a means for emitting light comprising a thin-film light-emitting source; and a means for coupling light comprising a first narrow portion, a second wide portion and a third narrow portion, the second wide portion interposed between the first narrow portion and the third narrow portion, said light-emitting means having one dimension that is substantially the same as the thickness of the light guiding means, wherein the light emitting means is disposed with respect to the first narrow portion such that the coupling means receives light from the light emitting means, and wherein said light emitting means is optically coupled to said light guiding means via the light coupling means such that light from the light-emitting means is directed into the light guiding means for providing light to the viewable portion of the display, said light coupling means substantially collimating the light directed into the light guiding means. - View Dependent Claims (24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36)

37. A method of manufacturing an illuminator for a display, the method comprising:
-
providing a light guide plate having first and second surfaces and a plurality of edges, said first and second surfaces substantially covering a viewable portion of the display; providing an optical component comprising a first narrow portion, a second wide portion and a third narrow portion, the second wide portion interposed between the first narrow portion and the third narrow portion; coupling the optical component to the light guide plate; and optically coupling an optical output surface of a thin-film light-emitting source to the first narrow portion of the optical component such that light from the light-emitting source is directed into the light guide plate via the optical component to provide light to the viewable portion of the display, said optical output surface of the light-emitting source being substantially perpendicular to said first surface of the light guide, wherein said thin-film light-emitting source has one dimension that is substantially the same as the thickness of the light guide plate. - View Dependent Claims (38, 39, 40, 41, 42, 43)
