Abstract

Exterior facing, multilayer display systems and methods of use are provided herein. An example method includes determining an amount of power for a multilayer display, the multilayer display having a first layer comprising a transparent display unit and a second layer comprising a reflective display unit, the second layer being bonded to the first layer, selecting the transparent display unit when the amount of the power is above a threshold amount, determining that amount of the power is above a threshold amount is below the threshold amount, and selecting the reflective display unit when the power is below the threshold amount.

First claim

That which is claimed is:

1. A vehicle, comprising:
a multilayer display comprising
a first layer comprising a transparent display unit, and
a second layer comprising a reflective display unit, wherein the second layer is bonded to the first layer, and wherein the multilayer display is mounted to the vehicle in such a way that the second layer is located between the first layer and a surface of the vehicle;
a vehicle platform configured to provide power to the multilayer display; and
a display control unit coupled to the vehicle platform, the display control unit configured to:
select the transparent display unit based on a determination that the vehicle is in a key on position, and select the reflective display unit based on a determination that the vehicle is in an accessory mode or a determination that the vehicle is turned off.

2. The vehicle according to claim 1 , further comprising a cover layer applied to the first layer.

3. The vehicle according to claim 1 , wherein the display control unit is configured to cause the reflective display unit to display a dark background when the transparent display unit is selected.

4. The vehicle according to claim 1 , wherein the display control unit is configured to activate a lighting element on the vehicle to illuminate the reflective display unit when the reflective display unit has been selected.

5. The vehicle according to claim 1 , further comprising an actuator, wherein the actuator is utilized to toggle between selection of the transparent display unit and the reflective display unit.

6. The vehicle according to claim 1 , wherein the transparent display unit comprises any of an Organic Light Emitting Diode (OLED) display, a Liquid Crystal Display (LCD), a Micro-LED display, and/or a Quantum Dot LED display.

7. The vehicle according to claim 1 , wherein the reflective display unit is a bi-stable display.

8. The vehicle according to claim 7 , wherein the bi-stable display is an electronic ink (E-ink) display or a bi-stable LCD.

9. A multilayer display associated with a vehicle, comprising:
a first layer comprising a transparent display unit;
a second layer comprising a reflective display unit,
the second layer disposed adjacent to the first layer; and
a display control unit configured to:
select the transparent display unit
based on a determination that the vehicle is in a key on position;
and select the reflective display unit
based on a determination that the vehicle is turned off.

10. The multilayer display according to claim 9 , further comprising a cover layer applied to the first layer.

11. The multilayer display according to claim 9 , wherein the display control unit is configured to cause the reflective display unit to display a dark background when the transparent display unit is selected.

12. The multilayer display according to claim 9 , wherein the reflective display unit is a bi-stable display.

13. The multilayer display according to claim 9 , wherein the display control unit is configured to activate a lighting element to illuminate the reflective display unit when the reflective display unit has been selected.

14. The multilayer display according to claim 9 , further comprising an actuator, wherein the actuator is utilized to toggle between selection of the transparent display unit and the reflective display unit.

15. The multilayer display according to claim 9 , wherein the transparent display unit comprises any of an Organic Light Emitting Diode (OLED) display, a Liquid Crystal Display (LCD), a Micro-LED display, and/or a Quantum Dot LED display.

16. The multilayer display according to claim 15 , wherein the reflective display unit is a bi-stable, electronic ink (E-ink) display.

17. A method, comprising:
determining an amount of power available to a multilayer display associated with a vehicle, the multilayer display comprising a first layer comprising a transparent display unit, and a second layer comprising a reflective display unit; and
selecting the transparent display unit based on a determination that the vehicle is in a key on position; or
selecting the reflective display unit based on a determination that the vehicle is in an accessory mode or a determination that the vehicle is turned off.

18. The method according to claim 17 , further comprising activating a lighting element on the vehicle to illuminate the reflective display unit when the reflective display unit has been selected.

19. The method according to claim 17 , further comprising causing the reflective display unit to display a dark background when the transparent display unit is selected to enhance contrast of content displayed on the transparent display unit.

20. The method according to claim 17 , further comprising changing content for display on the reflective display unit when the amount of power is available.
