Abstract:
Exemplary embodiments provide an electronic display assembly. One or more heat-generating components are preferably placed in thermal communication with a plate. One or more fans are placed to draw cooling air along the plate to remove the heat removed from the component. Some embodiments may place the plate behind the electronic image assembly, so that cooling air can remove heat from the plate as well as the electronic image assembly. Exemplary embodiments have power modules in thermal communication with optional conductive ribs. Conductive thermal communication is established between the optional ribs and the components in the exemplary embodiments.
Abstract:
Provided is a display device with a simplified configuration. The display device includes a display panel, a panel guide, a backlight unit, a front cover, and a back cover. The panel guide supports the display panel. The backlight unit emits light to the display panel. The front cover encloses an outer surface of the display panel. The backlight unit is stored in the back cover. The front cover includes a fixing portion formed thereon projecting toward the back cover, and the back cover includes a supporting portion projecting toward the backlight unit, to fix the front cover to the back cover.
Abstract:
Liquid crystal devices are described that maintain performance of polarization/amplitude modulation under high irradiance conditions. Configurations that isolate polarizing elements under high thermal load are discussed which allow other elements, such as glass, which may be sensitive to stress birefringence to remain near optimum thermal conditions.
Abstract:
The exemplary embodiments herein provide a figure eight closed loop of circulating gas pathways wrapping around an electronic display. One or more open loop ambient air pathways may pass through the figure eight but do not allow the circulating gas and the ambient air to mix. In some embodiments, the open loop ambient air pathway travels along a rear surface of the electronic display. In some embodiments, the circulating gas pathways contain a front channel placed in front of the electronic display, a rear channel placed behind the electronic display, and a center channel placed between the front and rear channels. Pass-through apertures may be placed within the path of the circulating gas and/or the ambient air to allow the paths of the two gaseous matters to cross without allowing them to mix with one another.
Abstract:
The illumination device 10 according to the present invention includes: a housing member 22 having a bottom plate 22a and a side wall 22b; a light guide plate 26 disposed on the inside of the side wall 22b in a manner so that a gap is formed between the side wall 22b and the side edge face 26b of the light guide plate 26; a light source unit having a light source 24 and a light source substrate 25 and disposed in the gap in a manner so that the substrate surface 25a faces the side edge face 26b; an optical sheet 23 disposed on the front surface 26a side of the light guide plate 26 and having an outer edge 23d protruding towards the light source substrate 25 from the side edge face 26b in a manner so as to cover and hide the bottom plate 22a at the section where the gap is; and a circulation hole X that pierces the light source substrate 25 or the housing member 22 in a manner such that the outside communicates with the air space S1 enclosed by the side edge face 26b, the substrate surface 25a, the bottom plate 22a, and the outer edge 23d.
Abstract:
A backlight unit 20 that radiates light toward a display panel 4 includes LEDs 22, a backlight chassis 21 that includes a rear surface side wall portion 21a that supports the LEDs 22, an insulating frame body 24 that forms a space covering a surface of the rear surface side wall portion 21a on the side opposite to the side on which the LEDs 22 are supported, a partition portion 24a that partitions a space inside the insulating frame body 24 into a plurality of regions, intake ports 24c that cause air to flow inside the insulating frame body 24, and exhaust ports 24d that cause air inside the insulating frame body 24 to be discharged, the intake ports 24c and the exhaust ports 24d being provided on the insulating frame body 24 so as to correspond to each of the regions partitioned by the partition portion 24a.
Abstract:
A waterproof user interface panel includes an electronic display assembly having a touch sensitive surface for activation of touch switches, and a housing including a cutout area. A protective film is disposed over the assembly and secured to the housing. The housing includes a top surface, a bottom surface and a peripheral sidewall to define a housing cavity. Sealing material covers the bottom surface, with a void between the top surface of the sealing material and the electronic display assembly. A vent is provided between the void and the external environment to allow air to pass. A filter may be positioned in the vent to prevent the passage of water droplets through the filter while allowing the passage of air and water vapor.
Abstract:
A gas cooling system for an electronic display is disclosed herein. A closed loop of circulating gas is preferably positioned to surround the electronic display. An open loop of cooling air preferably travels along the rear surface of the electronic display. In an exemplary embodiment the cooling air does not mix with the circulating gas. Heat may be transferred from the circulating gas to the cooling air in order to cool the display.
Abstract:
A panel type display device for minimizing temperature increase in the interior of a case and a display panel. The display device includes a case, a display panel mounted in an interior of the case, at least one circuit board for controlling the display panel, a first cooling fluid path for cooling the display panel, and a second cooling fluid path for cooling the circuit board. In the display device, the first and second cooling fluid paths are separated from each other.
Abstract:
A system for powering an LED backlight where power assemblies have electrical communications ran through pass through apertures in a mounting plate and LED backlight panel. A channel may be defined between the mounting plate and the LED backlight panel (or optional thermal plate attached to the rear portion of the LED backlight panel). Sub-channels can be created within the channel which are defined by ribs which connect between the mounting plate and the LED backlight panel (or optional thermal plate attached to the rear portion of the LED backlight panel). Cooling air can be prevented from entering one or more specific sub-channels so that electrical connections can pass through the mounting plate, LED backlight panel, and sub-channel without the risk of cooling air contaminates entering one of the pass through apertures.
