Electronic device with diffused backlit display
View Patent ↗An electronic device comprises a housing having a panel with an opening extending therethrough, a light source disposed within the electronic device and configured to transmit light through the opening, an optically-transmissive layer located on a side of the panel opposite a side of the light source and extending over the opening, and a reflective element disposed on the optically-transmissive layer and located at least partially coincident with a location of the opening.
1. A portable electronic device, comprising:
a housing having a panel with an opening extending therethrough;
a light source disposed within the electronic device and configured to transmit light through the opening;
an optically-transmissive layer located on a side of the panel opposite a side of the light source and extending over the opening; and
a reflective element disposed on the optically-transmissive layer and located at least partially coincident with a location of the opening, wherein the light transmitting through the opening impinges against the reflective element across the opening, wherein the light transmitting through the opening reflects from the reflective element to produce a silhouette-effect light pattern at the opening.
2. The device of claim 1 , wherein the reflective element has a shape that corresponds to a shape of the opening.
3. The device of claim 1 , wherein the reflective element is aligned with and disposed over the opening such that a location of the reflective element coincides with a location of the opening.
4. The device of claim 1 , wherein the optically-transmissive layer comprises an optically-transmissive coating applied to the panel.
5. The device of claim 1 , wherein the reflective element comprises a reflective surface facing the opening.
6. The device of claim 1 , wherein the housing comprises a display housing of a notebook computer.
7. The device of claim 1 , wherein the electronic device comprises at least one of the group of a notebook computer, a cellular telephone, a personal digital assistant, a tablet computer, and a gaming device.
8. The device of claim 1 , wherein the reflective element comprises a pattern corresponding to a pattern of the opening.
9. A method for manufacturing a portable electronic device, comprising:
providing a housing having a panel with an opening extending therethrough;
disposing a light source within the electronic device for transmitting light through the opening;
providing an optically-transmissive layer located on a side of the panel opposite a side of the light source, the optically-transmissive layer extending over the opening; and
locating a reflective element on the optically-transmissive layer, the reflective element located at least partially aligned with a location of the opening such that light transmits through the opening, impinges against the reflective element, and is reflected back to produce a silhouette-effect light pattern corresponding to the opening.
10. The method of claim 9 , further comprising forming the optically-transmissive layer by applying an optically-transmissive coating to the panel.
11. The method of claim 9 , further comprising locating a reflective surface of the reflective element facing the opening.
12. The method of claim 9 , further comprising providing the reflective element having a pattern corresponding to a pattern of the opening.
13. The method of claim 9 , wherein providing the optically-transmissive layer comprises providing a transparent layer.
14. A portable electronic device, comprising:
a housing having a panel with an opening extending from a first side of the panel to a second side of the panel;
a light source configured to transmit light through the opening from the first side toward the second side;
a reflective element aligned with and disposed over the opening to receive the light transmitting through the opening and reflect the light toward the second side of the panel; and
an optically-transmissive layer extending over the opening and located between the second side of the panel and the reflective element, wherein the light transmitting through the opening reflects from the reflective element to produce a silhouette-effect light pattern at the opening.
15. The device of claim 14 , wherein the optically-transmissive layer comprises a translucent layer.
16. The device of claim 14 , wherein the optically-transmissive layer comprises an optically-transmissive coating applied to the panel.
17. The device of claim 14 , wherein the reflective element comprises a reflective surface facing the second side of the panel.
18. The device of claim 14 , wherein the reflective element comprises a pattern corresponding to a pattern of the opening.
