Abstract

A display device, including: one or more layers of material having a light transmission region, a unit of information to be highlighted, and a light blocking region; and a backlight unit having a planar waveguide body, a light source configured to direct light into the waveguide body, and at least one light director associated with a portion of the waveguide body so as to direct light transversely to a plane of the waveguide body. The directed light travels through the light transmission region, and the directed light is directed toward the unit of information to be highlighted.

Claims (34)

1 . A display device, comprising:

one or more layers of material comprising a light transmission region, a unit of information to be highlighted, and a light blocking region;

a backlight unit comprising a planar waveguide body, a light source configured to direct light into the waveguide body, and at least one light director associated with a portion of the waveguide body so as to direct light transversely to a plane of the waveguide body,

wherein the directed light travels through the light transmission region, and wherein the directed light is directed toward the unit of information to be highlighted.

2 . The display device of claim 1 , comprising a plurality of backlight units, and at least one unit of information to be backlit per backlight unit.

3 . The display device of claim 2 , comprising a processor configured to control illumination of the backlight units so that the backlight units illuminate according to a predetermined pattern.

4 . The display device of claim 3 , comprising a sequence activation switch configured to trigger the illumination according to the predetermined pattern.

5 . A display device, comprising:

one or more layers of material comprising a light transmission region, a unit of information to be backlit, and a light blocking region;

a backlight unit comprising a planar waveguide body, a light source configured to direct light into the waveguide body, and at least one light director associated with a portion of the waveguide body so as to direct light transversely to a plane of the waveguide body, wherein the directed light travels through the light transmission region, and wherein the directed light is directed toward the unit of information to be highlighted;

a processor comprising a computer program code module that causes the processor to illuminate the backlight unit according to a predetermined pattern.

6 . The display device of claim 5 , comprising a plurality of backlight units, and at least one unit of information to be highlighted per backlight unit, wherein the computer program module controls illumination of the backlight units according to a predetermined pattern.

7 . (canceled)

8 . (canceled)

9 . A display device, comprising:

a translucent information layer substrate;

information associated with the translucent information layer substrate, comprising at least one unit of information to be highlighted;

a structural layer;

a light blocking layer comprising at least one light blocking layer opening that aligns with the at least one unit of information to be highlighted; and

a backlight system between the structural layer and the light blocking layer comprising at least one backlight unit and a power supply, wherein each backlight unit comprises a flexible, planar waveguide body, a light source mounted on the waveguide body, and at least one light director associated with a portion of the waveguide body so as to direct light transversely to a plane of the waveguide body and toward the at least one light blocking layer opening.

10 . The display device of claim 9 , wherein the at least one light director is a film attached to a surface of the portion of the waveguide body that aligns with the at least one light blocking layer opening.

11 . The display device of claim 9 , wherein the at least one light director is integral to the waveguide body and aligns with the at least one light blocking layer opening.

12 . The display device of claim 9 , wherein a light blocking layer opening shape matches and aligns with a respective shape of the at least one unit of information to be highlighted.

13 . The display device of claim 12 , wherein a light director shape matches and aligns with the shape of the at least one unit of information to be highlighted.

14 . The display device of claim 9 , wherein the backlight unit further comprises a light source blocking cover body between the light source and the light blocking layer.

15 . The display device of claim 9 , wherein the backlight unit further comprises a waveguide edge barrier covering edges of the waveguide body.

16 . The display device of claim 9 , wherein the backlight system further comprises a switch, wherein activation of the switch activates the light source.

17 . The display device of claim 9 , comprising a sound emitting device, wherein activation of a switch activates the sound emitting device.

18 . The display device of claim 9 , comprising a control circuit, wherein activation of a switch activates the control circuit, and wherein the control circuit controls power throughout the display device.

19 . The display device of claim 9 , wherein the at least one unit of information to be highlighted comprises a plurality of units of information to be highlighted, the light blocking layer comprises a plurality of openings that correspond to respective units of information to be highlighted, and the backlight system comprises a plurality of light directors corresponding to respective portions of the waveguide body that align with the light blocking layer openings.

20 . The display device of claim 19 , wherein the backlight system comprises a single backlight unit with which all the light directors are associated.

21 . The display device of claim 19 , wherein the backlight system comprises a plurality of backlight units.

22 . The display device of claim 21 , comprising a control circuit, wherein the control circuit controls power throughout the display device and illuminates each backlight unit according to a predetermined pattern.

23 - 40 . (canceled)
