Abstract

A low profile display enclosure system for enclosing a display device for viewing that protects the display device from environmental effects. The substantially sealed display enclosure comprises a rigid bezel, a substantially transparent front cover coupled to the bezel, and a rear cover assembly that may include a heat sink portion. A liquid organic coating is applied to portions of the display enclosure and cured in place in order to provide a protective surface.

Claims

1. A protectively enclosed flat panel display device having a display region viewable from outside an enclosure of a rigid bezel having a first opening covered by a substantially transparent front cover and a second opening substantially covered by a rear cover assembly, comprising a protective enclosure substantially impervious to liquid ingress under ambient conditions encountered in an outdoor environment, the protective enclosure including a sealant coating that coats at least a portion of the rigid bezel, the sealant coating providing a surface over the rigid bezel substantially impervious to liquid ingress.

2. The protectively enclosed flat panel display device of claim 1, wherein the sealant coating comprises an organic coating configured to adhere to the rigid bezel.

3. The protectively enclosed flat panel display device of claim 2, wherein the sealant coating comprises a polyurea material.

4. The protectively enclosed flat panel display device of claim 3, wherein the polyurea material comprises a sprayable material capable of being applied to the rigid bezel as a liquid and curable on the rigid bezel.

5. The protectively enclosed flat panel display device of claim 4, wherein the polyurea material comprise a plurality of components catalytically curable at about room temperature on the rigid bezel.

6. The protectively enclosed flat panel display device of claim 1, wherein the rigid bezel comprises a plurality of frame members defining a periphery of the protective enclosure, and a flat panel display device is disposed within the enclosure such that the display area of the display device is substantially aligned with the first opening.

7. The protectively enclosed flat panel display device of claim 6, wherein the rigid bezel defines a lower opening configured to receive the flat panel display device upon introduction of the flat panel display into the protective enclosure, and wherein the lower opening is sealable by a lower plate selectively attachable to the rigid bezel.

8. A display enclosure for enclosing a flat panel display device for viewing in an outdoor environment, comprising:

a bezel defining a perimeter surface describing an enclosure area having a display opening covered by a substantially transparent front cover coupled to the bezel and a rear opening substantially covered by a rear cover assembly coupled to the bezel;

an organic coating disposed on the perimeter surface and forming a weather resistant seal over the bezel, wherein the coated rigid bezel, the front cover and the rear cover substantially define the display enclosure configured to receive a the flat panel display device therein, and wherein the display enclosure is resistant to liquid ingress in an outdoor viewing environment.

9. The display enclosure of claim 8, wherein the organic coating comprises a polyurea material.

10. The display enclosure of claim 9, wherein the polyurea material comprises a sprayable material capable of being applied to the bezel.

11. The display enclosure of claim 9, wherein the polyurea material comprises a two-component material curable at room temperature.

12. The display enclosure of claim 10, wherein the bezel comprises an assembly of a plurality frame members.

13. The display enclosure of claim 8, wherein the rigid bezel further comprises:

a rear surface extending inwardly from a rear edge of the perimeter surface and defining the rear opening; and

a front surface extending inwardly from a front edge of the perimeter surface and defining the display opening.

14. A method of preparing a substantially sealed protective enclosure for a display device, comprising:

assembling a rigid bezel by joining a plurality of frame members, the rigid bezel characterized by a display opening and a rear opening, the rigid bezel including a plurality of lateral surfaces substantially defining an outer peripheral surface of the protective enclosure;

applying a liquid sealant on the outer peripheral surface;

curing the liquid sealant to form a protective coating on the rigid bezel;

attaching a front cover to the rigid bezel, the front cover covering the display opening;

attaching a rear cover to the rigid bezel, the rear cover covering at least a portion of the rear opening; and

placing a display device within the enclosure, the display device including a display area viewable through the front cover.

wherein the protective enclosure is substantially impervious to precipitation in an outdoor environment.

15. The method of claim 14, wherein the liquid sealant is applied after the assembly of the rigid bezel.

16. The method of claim 14, wherein the liquid sealant is applied by spraying onto the outer peripheral surface.

17. The method of claim 16, wherein the liquid sealant comprises a two-component polyurea having a catalyst component configured to effectuate curing at room temperature.

18. The method of claim 17, wherein the liquid sealant is heated prior to spraying.

19. The method of claim 14, wherein the rigid bezel is further characterized by a lower opening, and wherein the display is placed within the enclosure by insertion through the lower opening.
