Abstract

A display unit for mounting in a vehicle may include an image generator, a display member, and a light source. The display member may be configured to move from a non-operational position to an operational position such that the display member is positioned to reflect light from the image generator in the operational position. The display member also includes an edge configured to refract light and/or otherwise be illuminated. The light source may be configured to emit light to illuminate at least a portion of the edge of the display member. In some implementations, the light source may move when the display member is moved from the non-operational position to the operational position. In other implementations, the light source may be stationary. The display unit may also include a light guide to guide the light emitted by the light source to illuminate the edge.

Claims

1. A display unit for mounting in a vehicle, comprising:

an image generator;

a display member configured to move from a non-operational position to an operational position, wherein the display member is positioned to reflect light from the image generator in the operational position, the display member having an edge configured to refract light; and

a light source configured to emit light to illuminate at least a portion of the edge of the display member.

2. The display unit of claim 1, wherein the edge is grained.

3. The display unit of claim 1, wherein the light source is a light emitting diode.

4. The display unit of claim 1 further comprising:

a light guide interposed between the light source and the display member, wherein the light guide is configured to guide emitted light to a portion of the display member.

5. The display unit of claim 4, wherein the portion of the display member comprises an angled portion, wherein the angled portion is configured to redirect the emitted light through the edge of the display member.

6. The display unit of claim 5, wherein the light source is mounted to a separate stationary printed circuit board within the display unit, wherein the stationary printed circuit board does not move when the display member moves from the non-operational position to the operational position.

7. The display unit of claim 5, wherein the light source is mounted to a separate printed circuit board configured to move with the display member when the display member moves from the non-operational position to the operational position.

8. The display unit of claim 5, wherein the light source is mounted to a main printed circuit board.

9. The display unit of claim 1 wherein a color of the emitted light is user-selectable.

10. The display unit of claim 1, wherein an intensity of the emitted light is user-selectable.

11. The display unit of claim 1, wherein an intensity of the emitted light is variable, wherein a controller is configured to modify the intensity of the emitted light to communicate information to a driver.

12. The display unit of claim 11, wherein the information comprises at least one of a collision indication, a speed indication, a brake indication, or a system warning indication.

13. The display unit of claim 1, wherein the light source is a first light source emitting a first light to illuminate a first portion of the edge of the display member, the display unit further comprising:

a second light source emitting a second light to illuminate at least a second portion of the edge of the display member.

14. The display unit of claim 13, wherein the first light of the first light source is a first color and the second light of the second light source is a second color, wherein the first color and the second color are different colors, wherein a region of the edge of the display member is indicated by an overlap of the first color and the second color.

15. The display unit of claim 14, wherein a first intensity of the first light source is variable, wherein a controller is configured to modify the first intensity of the emitted first light to communicate information to a driver.

16. The display unit of claim 15, wherein the information comprises information indicative of at least one of a rotation rate, a speed rate, a tachometer, a speedometer, a downloading rate, an upload rate, a signal strength, a charging rate, a charging status, a fuel level, a fuel consumption rate, a fuel efficiency, a temperature, an air conditioner temperature setting, a fan speed, a transmission temperature, a battery charging rate, a battery discharging rate, a battery charge level, a tire pressure, a tire temperature, an oil level, an oil temperature, an oil purity, a temperature of a glow plug, an engine temperature, a differential temperature, a seat temperature, a cruise control speed, an acceleration rate, an adaptive cruise control speed, a traction control status, a differential status, a shift efficiency, a door status, a door position, a gas door position, a window status, a window position, a moon roof status, a moon roof position, a convertible top status, a convertible top position, a lift gate status, a lift gate position, a washer fluid level, a transmission fluid level, a distance-to-empty, an incline position, an incline rate of change, a body roll rate, a body roll position, a lateral acceleration, a turbo temperature, a turbo pressure, a turbo speed, a turbo boost, a radio station, a preset, a balance, a vent position, a distance to an object, a back-up sensor indicator, a blind spot indicator, a lane departure indicator, a Bluetooth®
