Abstract

A low profile display enclosure system for enclosing a display device for viewing that protects the display device from environmental effects and is configured to dissipate heat generated within the display enclosure. The substantially sealed display enclosure comprises a rigid bezel, a substantially transparent front cover coupled to the bezel, and a rear cover assembly that includes a heat sink portion. The thickness of the bezel is minimized to provide the enclosure with a low profile about the periphery of the display device enclosed therein. Thermal control devices may be mounted within the enclosure to modulate a temperature within the enclosure.

Claims

1. A protectively enclosed flat panel display device viewable from outside the enclosure, comprising:

a protective enclosure substantially impervious to liquid ingress under ambient conditions encountered in an outdoor environment, the protective enclosure comprising;

a rigid bezel defining a periphery of the protective enclosure, the rigid bezel characterized by a front bezel surface having a first opening and the rigid bezel further characterized by a second opening substantially opposite the first opening,

a substantially transparent front cover coupled to the front bezel surface and covering the first opening, and

a rear cover assembly coupled to the rigid bezel and covering the second opening, at least a portion of the rear cover assembly comprising a heat sink portion, the rear cover assembly further including a cable entry;

a flat panel display device disposed within the enclosure such that the display area of the display device is substantially aligned with the first opening;

a heat pipe assembly having a first attachment portion coupled to the display device, and a second attachment portion coupled to the rear cover assembly;

a thermal control unit disposed within the enclosure and electrically coupled to a power source, the thermal control unit including a temperature sensor; and

at least one thermal control device disposed at least partially within the enclosure and electrically coupled to the thermal control unit, the at least one thermal control device controllable by the thermal control unit to modulate an internal temperature within the enclosure.

2. The protectively enclosed flat panel display device of claim 1, wherein the at least one thermal control device is selected from the group consisting of a heating element and a fan.

3. The protectively enclosed flat panel display device of claim 2, wherein the heating element comprises a strip heater configured to maintain the internal temperature above a low threshold temperature of the display device.

4. The protectively enclosed flat panel display device of claim 2, wherein the thermal control unit is configured to modulate the internal temperature between the lower threshold temperature and an upper threshold temperature of the display device.

5. The protectively enclosed flat panel display device of claim 1, further comprising a power supply disposed within the enclosure, the power supply thermally coupled to the rear cover assembly, and the power supply configured to supply electrical power to the display device, the thermal control unit and the at least one thermal control device.

6. The protectively enclosed flat panel display device of claim 1, 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.

7. The protectively enclosed flat panel display device of claim 1, wherein the rigid bezel further includes a front cover ledge configured to accept a portion of the substantially transparent front cover, and wherein the portion of the substantially transparent front cover is adhered to the rigid bezel, thereby forming a substantially water tight interface between the substantially transparent front cover and the rigid bezel.

8. The protectively enclosed flat panel display device of claim 1, wherein the substantially transparent front cover comprises a glass cover, the glass cover including an ultraviolet treatment to mitigate transmission of ultraviolet radiation to the display device, the glass cover further including an anti-reflective treatment to reduce reflection by the s glass cover.

9. The protectively enclosed flat panel display device of claim 1, wherein the rigid bezel comprises a low profile bezel characterized by a bezel thickness defined by the normal distance between the periphery and the first opening, and wherein the bezel thickness is less than about 50 mm.

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

a rigid bezel, the rigid bezel characterized by a perimeter surface defining an enclosure area, the rigid bezel comprising;

a perimeter surface having a rear edge and a front edge;

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

a front surface extending inwardly from the front edge and defining a display opening, the display opening characterized by an area at least about 85 percent of the enclosure area;

a substantially transparent front cover coupled to the front surface and disposed over the display opening; and

a rear cover assembly coupled to the rear surface and covering the rear opening, at least a portion of the rear cover assembly comprising a heat sink portion configured to dissipate heat generated within the display enclosure to the environment,

wherein the rigid bezel, the front cover and the rear cover substantially define the display enclosure configured to receive the flat panel display device therein, and wherein the display enclosure is resistant to liquid ingress in an outdoor viewing environment.

11. The display mount of claim 11, further comprising a heat pipe positioned within the display enclosure, the heat pipe including a first portion coupled to the rear cover assembly and a second portion configured for operative attachment to the display device.

13. The display enclosure of claim 11, wherein the display opening is at least about 93 percent of the enclosure area.

14. The display enclosure of claim 11, wherein the front cover comprises a substantially transparent glass cover having a peripheral region extending over and adhered to a portion of the front surface, thereby providing a substantially water tight interface between the front surface and substantially transparent glass cover;

and wherein a substantially opaque coating is disposed on at least one surface of the substantially transparent glass cover in the peripheral region.

12. The display mount of claim 12, further comprising:

a thermal control unit located within the display enclosure, the thermal control unit configured to receive a temperature input from a temperature sensing element responsive to a temperature within the enclosure; and

a selectively operable thermal control device located within the enclosure and electrically coupled to the thermal control unit.

15. An enclosed display device, comprising:

a substantially sealed protective enclosure configured for outdoor use, the protective enclosure comprising;

a rigid bezel having a low profile characterized by a display opening, a lower opening and a rear opening, the rigid bezel including a plurality of lateral surfaces substantially defining an outer peripheral surface of the protective enclosure and an inner edge defining the display opening, the inner edge substantially parallel to the outer peripheral surface and displaced inwardly from the outer peripheral surface by a bezel thickness,

a rear cover selectively coupled to the rigid bezel and configured to cover the rear opening, the rear cover including a heat sink portion;

a lower plate selectively coupled to rigid bezel and configured to cover the lower opening;

a display device disposed within the enclosure, the display device including a display area viewable through the front cover;

wherein the bezel thickness is minimized to define a low profile bezel, and wherein the substantially sealed protective enclosure is impervious to precipitation.

16. The enclosed display device of claim 15, wherein the bezel thickness is less than about 25 mm.

17. The enclosed display device of claim 15, further comprising:
