1. A display device, comprising in combination:
- an opaque cover member;
a support panel spaced from said opaque cover member so as to define, with said opaque cover member, a space between said support panel and said opaque cover member;
a first light source mounted upon said support panel so as to be disposed within said space defined between said support panel and said opaque cover member;
first light concentrator means, mounted upon said opaque cover member such that a first end portion of said first light concentrator is accessible from a position external to an outer surface portion of said opaque cover member, and a body portion of said first light concentrator means is disposed within said space such that a second end portion of said first light concentrator means is disposed adjacent to said first light source, for evenly distributing and diffusing light from said first light source to said outer surface portion of said opaque cover member;
a second light source mounted upon said support panel so as to also be disposed within said space defined between said support panel and said opaque cover member, and be in a spaced-apart but close relationship with respect to said first light source;
second light concentrator means, mounted upon said opaque cover member such that a first end portion of said second light concentrator means is accessible from a position external to said outer surface portion of said opaque cover member, and a body portion of said second light concentrator means is disposed within said space such that a second end portion of said second light concentrator means is disposed adjacent to said second light source, for evenly distributing and diffusing light from said second light source to said outer surface portion of said opaque cover member; and
opaque light-shielding means integrally formed with said opaque cover member and extending from said opaque cover member to a position immediately adjacent to said support panel so as to be interposed between said first light source and its associated first light concentrator means, and said second light source and its associated second light concentrator means, and to divide said space into first and second cells separated by and defined upon opposite sides of said light-shielding means, for preventing light from being transmitted from one of said first and second light sources disposed within one of said first and second cells to the other one of said first and second light sources and its corresponding light concentrator means disposed within the other one of said first and second cells.

Abstract
A display device includes a pair of first and second light sources arranged on a printed circuit board in a spaced-apart but close relationship to each other. A light-shielding tab is interposed between the first and second light sources for shielding light from an illuminated one of the pair of light sources from being transmitted to the other one of the light sources.

13. A display device, comprising in combination:
-
an opaque cover member; a support panel spaced from said opaque cover member so as to define, with said opaque cover member, a space between said support panel and said opaque cover member; a first light source disposed upon said support panel and having a first longitudinal extent such that said first light source is disposed within said space defined between said support panel and said opaque cover member; first light concentrator means, having stepped ribs for fixedly mounting said first light concentrator means within said opaque cover member such that a first end portion of said first light concentrator means is accessible from a position external to an outer surface portion of said opaque cover member, while a body portion of said first light concentrator means is disposed within said space defined between said support panel and said opaque cover member such that a second end portion of said first light concentrator means is disposed adjacent to said first light source, for evenly distributing and diffusing light from said first light source to said outer surface portion of said opaque cover member; a second light source disposed upon said support panel in a spaced-apart but close relationship with respect to said first light source and having a second longitudinal extent such that said second light source is disposed within said space defined between said support panel and said opaque cover member; second light concentrator means, having stepped ribs for fixedly mounting said second light concentrator means within said opaque cover member such that a first end portion of said second light concentrator means is accessible from a position external to said outer surface portion of said opaque cover member, while a body portion of said second light concentrator means is disposed within said space defined between said support panel and said opaque cover member such that a second end portion of said second light concentrator means is disposed adjacent to said second light source, for evenly distributing and diffusing light from said second light source to said outer surface portion of said opaque cover member; and opaque light-shielding means integrally formed with said opaque cover member, having a third longitudinal extent which is at least as great as said first and second longitudinal extents of said first and second light sources, and extending from said opaque cover member to a position immediately adjacent to said support panel so as to be interposed between said first light source and its associated first light concentrator means, and said second light source and its associated second light concentrator means, and to divide said space defined between said support panel and said opaque cover member into first and second cells separated by and defined upon opposite sides of said light-shielding means, for substantially preventing light from being transmitted from an illuminated one of said first and second light sources disposed within one of said first and second cells to the other one of said first and second light sources and its corresponding light concentrator means disposed within the other one of said first and second cells along substantially the entire longitudinal extents of said first and second light sources. - View Dependent Claims (14, 15, 16, 17, 19, 21)
