First Claim
1. An outdoor electronic display comprising:
- a housing including an openable and closeable portion to access an interior of the housing;
a weatherized electronic display panel retained in the housing;
a backlight retained in the housing;
a diffuser positioned in the housing between the weatherized electronic display panel and the backlight;
a first airspace defined between the diffuser and the backlight; and

Abstract
An electronic display panel is ruggedized by optically bonding optically transparent plates to the front and back of the display panel. Electronic devices associated with the display panel, such as drivers, may be encased in a resin or other material to provide environmental and mechanical protection for the electronic devices. An outdoor display device includes a two part housing with a weatherized electronic display panel mounted in one part and a back light mounted in the second part. The housing is easily opened at the display device location to provide access to the back light components and the back of the weatherized electronic display panel for maintenance or other purposes. Fans and air passages may be provided to circulate air through the housing to help cool the display device.

18. An outdoor electronic display device comprising:
-
a housing means for sheltering an electronic display panel and its associated electronics; a weatherized electronic display panel means for showing images; a backlight means for providing light to a non-viewer side of the weatherized display panel means; a diffuser means for diffusing light from the backlight means before said light reaches the weatherized display panel means; a cooling passage means including a first portion located between the electronic display panel means and the diffuser means and a second portion located between the diffuser means and the backlight means for guiding flowing air through the housing means; and an airflow means for flowing air from outside the housing means through the cooling passage means and back outside the housing means.

19. An outdoor electronic display device comprising:
-
a housing; a backlight in the housing; an electronic display panel retained in the housing having a viewer side and an opposing non-viewer side; a front optically transparent plate optically bonded to the viewer side of the electronic display panel by an optical adhesive layer, wherein the front optically transparent plate extends beyond at least one edge of the electronic display panel; and a bonding material encasing a periphery of the electronic display panel and encasing electronics associated with the electronic display panel to seal the electronics from an outside environment and to mechanically attach the electronics to the front optically transparent plate to provide stability and support for the electronics. - View Dependent Claims (20, 21)
