Variable transparencies applied to aircraft seats
The field of this disclosure relates to the use of variable transparency technology on aircraft seats. Specifically, there is described a system that uses a transparent material that can be transitioned to become more opaque upon application of a voltage. The transparent material may be used for privacy purposes, may be used to create a video screen on a selected surface, or for other uses described herein.
1. A privacy panel configured to be positioned between passenger seats or on a seat shell, the privacy panel comprising:
a variable transparency panel having a first condition in which the panel is transparent and a second condition in which the panel is made at least partially opaque via application of a voltage to the panel,
wherein, in the second condition, the panel functions as a screen for displaying content,
wherein the variable transparency panel comprises a first variable transparency panel and a second variable transparency panel associated with the first variable transparency panel,
wherein the second variable transparency panel is configured to provide light blockage for the first variable transparency panel,
wherein the first variable transparency panel comprises a passenger-facing panel that functions as a viewing screen and wherein the second variable transparency panel is configured to be darkened to provide light blockage for the first variable transparency panel.
2. The in-flight entertainment unit of claim 1 , further comprising a projector configured to display content onto the panel.
3. The in-flight entertainment unit of claim 1 , wherein the panel is secured to a forward seat's seatback.
4. The in-flight entertainment unit of claim 1 , wherein the panel is secured to a rotating arm configured to move the panel with respect to a seated passenger.
5. The in-flight entertainment unit of claim 1 , wherein, in the second condition, the panel is activated to white.
6. The in-flight entertainment unit of claim 1 , wherein the panel is individually controlled such that each passenger controls viewing content.
7. The in-flight entertainment unit of claim 1 , wherein the panel is controlled via a master controller.
8. The in-flight entertainment unit of claim 1 , wherein the variable transparency panel comprises glass, plastic, acrylic, polycarbonate, polystyrene, cellulose, crystal, ceramic, lacquer, urethane, epoxy, resin, or any combination thereof.
9. The in-flight entertainment unit of claim 1 , wherein the variable transparency panel comprises electrochromatic or smart glass.
10. The in-flight entertainment unit of claim 1 , wherein the variable transparency panel is adhered to a surface using an adhesive, a mechanical fastener, quarter turn locks, or any combination thereof.
11. The in-flight entertainment unit of claim 1 , wherein the variable transparency panel comprises one or more light emitting diodes configured to change colors of the panel.
12. A method for viewing entertainment content from a passenger seat, comprising:
activating the in-flight entertainment unit of claim 1 from a transparent condition to a non-transparent condition; and
projecting viewing content on the in-flight entertainment unit.
13. The method of claim 12 , wherein activating the in-flight entertainment unit from a transparent condition to a non-transparent condition comprises application of a voltage to the panel.
14. The method of claim 12 , wherein activating the in-flight entertainment unit from a transparent condition to a non-transparent condition comprises activating a user-controlled panel to turn the panel white.
