Wireless video transmission system for liquid crystal display
View Patent ↗The exemplary embodiments herein provide a sealed transparent LCD assembly having a front and rear glass panel with a spacer positioned between the two panels to provide a sealed cavity containing a liquid crystal display (LCD). A wireless transmitter/receiver may be placed within the sealed cavity to receive image or video data wirelessly. The sealed transparent LCD assembly may be used with a display case which defines a cavity housing a second wireless transmitter/receiver which can push the image or video data to the wireless transmitter/receiver contained within the sealed cavity between the two glass panels.
1. A sealed transparent LCD assembly comprising:
a front glass panel;
a rear glass panel;
a spacer positioned around a perimeter of the front and rear glass panels and sandwiched in between the front and rear glass panels to provide a gaseous seal between the front glass panel and the spacer as well as between the rear glass panel and the spacer;
a liquid crystal display (LCD) panel positioned between the front and rear glass panels; and
a wireless transmitter/receiver positioned adjacent to the LCD and between the front glass panel and rear glass panel.
2. The sealed transparent LCD assembly of claim 1 further comprising:
a plate bonded to the rear glass panel.
3. The sealed transparent LCD assembly of claim 2 wherein:
the wireless transmitter/receiver is attached to the plate.
4. The sealed transparent LCD assembly of claim 3 wherein:
the plate provides conductive thermal communication between the wireless transmitter/receiver and the rear glass.
5. The sealed transparent LCD assembly of claim 1 further comprising:
argon gas sealed between the front and rear glass panels and contacting the wireless transmitter/receiver.
6. The sealed transparent LCD assembly of claim 1 wherein:
the wireless transmitter/receiver accepts video data from a device placed outside of the sealed transparent LCD assembly.
7. The sealed transparent LCD assembly of claim 1 wherein:
the front and rear glass are positioned within a display case.
8. The sealed transparent LCD assembly of claim 1 wherein:
the front and rear glass are positioned within the door frame of a display case.
9. A display case comprising:
a housing;
a cavity within the housing;
a first wireless transmitter/receiver positioned within the cavity in the housing;
a door frame;
a transparent LCD assembly positioned within the door frame and comprising
a front glass panel,
a rear glass panel,
a liquid crystal display positioned between the front glass and rear glass panels, and
a spacer which surrounds the liquid crystal display and is sandwiched in between the front and rear glass panels to create a sealed cavity,
a second wireless transmitter/receiver positioned within the sealed cavity.
10. The display case of claim 9 further comprising:
a plate bonded to the rear glass panel.
11. The display case of claim 10 wherein:
the second wireless transmitter/receiver is attached to the plate.
12. The display case of claim 9 further comprising:
argon gas sealed between the front and rear glass panels and contacting the second wireless transmitter/receiver.
13. A display case comprising:
a housing;
a cavity within the housing;
a first wireless transmitter/receiver positioned within the cavity in the housing; and
a transparent LCD assembly positioned in front of the housing and comprising
a front glass panel,
a rear glass panel,
a spacer positioned around a perimeter of the front and rear glass panels and sandwiched in between the front and rear glass panels to define a gaseously sealed cavity, and
a liquid crystal display (LCD) panel positioned within the gaseously sealed cavity, and
a second wireless transmitter/receiver positioned within the gaseously sealed cavity which receives image data from the first wireless transmitter/receiver.
14. The display case of claim 13 further comprising:
a plate bonded to the rear glass panel.
15. The display case of claim 14 wherein:
the second wireless transmitter/receiver is attached to the plate.
16. The display case of claim 14 wherein:
the plate provides conductive thermal communication between the second wireless transmitter/receiver and the rear glass.
17. The display case of claim 13 further comprising:
argon gas sealed between the front and rear glass panels and contacting the second wireless transmitter/receiver.
18. The display case of claim 13 wherein:
the cavity within the housing is positioned below the transparent LCD assembly.
19. The display case of claim 13 wherein:
the spacer comprises a flexible foam that contains a desiccant.
20. The display case of claim 13 wherein:
the spacer defines the amount of spacing between the front glass panel and rear glass panel.
