Electronic display projection assembly having substantially white off state
View Patent ↗One or more embodiments of a method and apparatus taught herein provide an electronic display projection assembly that comprises an electronic display configured to display an image, and a transparent glass layer positioned on one side of the electronic display on which the image is displayed. A projection layer is located on a surface of the glass layer. A projecting layer is positioned between the electronic display and the glass layer, and comprises a plurality of microlenses for projecting the displayed image onto the projection layer. The projecting and projection layers may be located on either opposing sides of the transparent glass layer, or on the same side beneath the glass layer. A corresponding method of providing an image from an electronic display is also disclosed.
1. An electronic display projection assembly, comprising:
an electronic display configured to display an image;
a glass layer positioned on a side of the electronic display on which the image is displayed, wherein the glass layer is transparent;
a projection film layer on a surface of the glass layer; and
a projecting film layer positioned between the electronic display and the glass layer, and comprising a plurality of microlenses for projecting the displayed image either through the glass layer onto the projection film layer, or onto the projection film layer for viewing through the glass layer;
wherein the projection film layer is translucent, and reflects substantially white light when the electronic display is in an OFF state.
2. The electronic display projection assembly of claim 1 , wherein the electronic display is a liquid crystal display (LCD).
3. The electronic display projection assembly of claim 1 , wherein the transparent glass layer comprises a touch screen input device.
4. The electronic display projection assembly of claim 1 , wherein the projecting film layer is configured to stretch the projected image to outer edges of the glass layer.
5. The electronic display projection assembly of claim 1 , wherein the electronic display includes a collimated backlight.
6. The electronic display projection assembly of claim 1 , wherein the electronic display has a plurality of pixels, each pixel including at least three sub-pixels, and wherein an area of each microlens is smaller than an area of each sub-pixel.
7. The electronic display projection assembly of claim 6 , wherein the area of each microlens is also smaller than a spacing area between adjacent pixels or a spacing area between adjacent sub-pixels.
8. The electronic display projection assembly of claim 1 , wherein the projecting film layer comprises a plurality of plastic layers arranged to form the microlenses.
9. A method of providing an image from an electronic display, comprising:
displaying an image from an electronic display onto a projecting film layer comprising a plurality of microlenses; and
projecting the displayed image through the plurality of microlenses and either through a glass layer onto a projection film layer on the glass layer, or onto the projection layer for viewing through the glass layer, wherein the glass layer is transparent;
wherein the projection film layer is translucent, and reflects substantially white light when the electronic display is in an OFF state.
10. The method of claim 9 , wherein the electronic display is a liquid crystal display (LCD).
11. The method of claim 9 , wherein the transparent glass layer comprises a touch screen input device.
12. The method of claim 9 , wherein the projecting film layer is configured to stretch the projected image to outer edges of the glass layer.
13. The method of claim 9 , wherein the electronic display includes a collimated backlight.
14. The method of claim 9 , wherein the electronic display has a plurality of pixels, each pixel including at least three sub-pixels, and wherein an area of each microlens is smaller than an area of each sub-pixel.
15. The method of claim 14 , wherein the area of each microlens is also smaller than a spacing area between adjacent pixels or a spacing area between adjacent sub-pixels.
16. The method of claim 9 , wherein the projecting film layer comprises a plurality of plastic layers arranged to form the microlenses.
