Description
TECHNICAL FIELD

Embodiments generally relate to cooling systems and methods for installing electronic displays.


BACKGROUND OF THE ART

Electronic displays are sometimes used in outdoor environments or other areas where the surrounding temperatures may be high or there may be other sources of heat such as solar loading causing the temperatures within the display to rise. However, some portions of the display can be difficult to cool as simply ingesting ambient air into some portions of the display can introduce dust and contaminates into sensitive portions of the display, which can lead to premature failures. In some spaces, only a small footprint is available, such that placing electronic displays in a back to back orientation is desirable.


SUMMARY OF THE EXEMPLARY EMBODIMENTS

Exemplary embodiments provide a back to back electronic display assembly where the electronic components are contained within a sealed plenum. External air is ingested and passed between the walls of the plenum and the rear surfaces of the electronic display assemblies. The two electronic display assemblies are permitted to move relative to one another, such that the plenum can be easily opened with the electronics made available for servicing and/or replacement.


The foregoing and other features and advantages of the present invention will be apparent from the following more detailed description of the particular embodiments, as illustrated in the accompanying drawings.

FIG. 1 is a front planar view of an exemplary back to back display assembly 1000 showing the vertical section line A-A. In this orientation the first display assembly 201 is the only display that is viewable.



FIG. 2 is a section view taken along the section line A-A and showing Detail 3 and Detail 4 as well as vertical section line B-B. A first display assembly 201 is positioned back-to-back with a second display assembly 401. In an exemplary embodiment, the two display assemblies 201 and 401 are substantially parallel with the rear surfaces of each display assembly facing each other. The first display assembly 201 preferably contains a front cover glass 200, LCD panel 210, and LED backlight 220. The second display assembly 401 preferably contains a front cover glass 400, LCD panel 410, and LED backlight 420. Although shown and described herein with LED backlight LCD technology, the exemplary embodiments herein can be practiced with any form of flat panel display, including but not limited to OLED, LED, plasma, and any luminescent polymers. In these embodiments, the rear surface of the LED backlight would simply be the rear surface of an OLED, LED, plasma, or a luminescent polymer display.


An enclosed plenum 500 preferably contains the electronics 800 for operating the two displays and is positioned between the two display assemblies 201 and 401. A fan 600 is also positioned between the two display assemblies 201 and 401 and is positioned to draw surrounding external air through the assembly 1000, preferably without permitting any of the external air to enter the plenum 500. Although only a single fan 600 is shown, multiple fans may be used in some embodiments, either in the same or a different location than the fan 600 which is shown. Further, while the fan 600 is shown pulling the external air through the assembly 1000, it could also be positioned to push the external air through the assembly 10000. Still further, although shown at the bottom of the display assembly 1000, it could instead be placed at the top.



FIG. 3 is a detailed section view showing Detail 3. FIG. 4 is a detailed section view showing Detail 4. The plenum 500 is preferably enclosed by a first wall 740 which faces the first display assembly 201, a second wall 730 which faces the second display assembly 401, a top wall 710, bottom wall 715, and a pair of opposing sidewalls 701 (not shown in this view). In this embodiment, the first wall 740, a top wall 710, bottom wall 715, and opposing sidewalls 701 are fixed relative to one another while the second wall 730 is movable relative to these pieces. While this is shown here, other embodiments could fix the second wall 730 relative to the top wall 710, bottom wall 715, and opposing sidewalls 701 while the first wall 740 is movable relative to these pieces. Preferably, the walls 740, 710, 715, 730, and the sidewalls 701 are metallic and preferably aluminum.


The second wall 730 seals the plenum 500 when the gasket 700 is compressed between the second wall 730 and the top wall 710, bottom wall 715, and opposing sidewalls 701. The electronics 800 contained within the plenum are protected from the external air flows 575 and 550 and any possible contaminates, particulate, or water vapor that may be present. The electronics can include, but are not limited to: power supplies, microprocessors, printed circuit boards, electronic memory, transmitting/receiving devices, and video players. Preferably the electronics 800 are also in thermal communication (preferably conductive) with either the first wall 740, second wall 730, or both. In this way, heat from the electronics 800 can be transferred to the first wall 740 to be removed by first external air flow 575 or the second wall 730 to be removed by the second external air flow 550.


A first gap is preferably defined between the first display assembly 201 and the first wall 740 of the plenum 500. A second gap is defined between the second display assembly 401 and the second wall 730 of the plenum 500. In this particular embodiment where an LCD with an LED backlight is being used, the first gap is between the rear surface of the LED backlight 220 and the first wall 740 and the second gap is between the rear surface of the LED backlight 420 and the second wall 730. A first external airflow 575 is ingested into the housing through an inlet aperture, forced through the first gap, and then exhausted out of the housing through an exhaust aperture. A second external airflow 550 is ingested into the housing through an inlet aperture, forced through the second gap, and then exhausted out of the housing through an exhaust aperture. In this way, airflow 575 can remove heat simultaneously from the LED backlight 220 and the first wall 740 while airflow 550 can remove heat simultaneously from the LED backlight 420 and the second wall 730.



FIG. 5 is a section view taken along the section line A-A and showing the second display assembly rotated away from the first display assembly and also showing Detail 6. In this embodiment, the first display assembly 201 remains fixed while the second display assembly 401 is permitted to move or rotate away from the first display assembly 201, providing access to the interior of the plenum and the electronics 800 inside.



FIG. 6 is a detailed section view showing Detail 6. Here, a sloped rain catcher 705 is placed below the inlet aperture and above the plenum so as to collect any condensation and direct it down the first gap. This figure also shows the movement of the second wall 730 along with the second display assembly 401, as they move away from the first wall 740, a top wall 710, bottom wall 715, and opposing sidewalls 701 to provide access to the interior of the plenum.



FIG. 7 is a perspective view showing an alternate embodiment where the first display assembly 201 is rotated away from the second display assembly 401 (which remains fixed). Here, a pair of gas springs 850 are used to help rotate the display assembly 201 and hold it in an open position while the interior of the plenum 500 is being serviced.



FIG. 8 is a perspective view taken along the line B-B and indicating Detail 9. In this embodiment, the first wall 740 is used to mount the various electronics 800, although these could instead be mounted to the rear wall 730. In some embodiments, electronics 800 may be mounted to both the first wall 740 and the second wall 730. The top wall 710 substantially prohibits airflow from entering the plenum. An opening 120 is preferably placed on or near the top wall 710 to allow airflow 575 to enter the gap defined by the opening of the space between the first wall 740 and the rear of the LED backlight 220. In a similar manner, another opening (not shown here) is preferably provided on or near the top wall 710 to allow airflow 550 to enter the gap defined by the opening of the space between the second wall 730 and the rear of the LED backlight 420.


A gasket 700 is preferably positioned around the perimeter of the first wall 740 so that the gasket 700 is compressed between the plenum walls (top wall 710, bottom wall 715, and pair of opposing sidewalls 701) and the second wall 730 when the unit is closed. Preferably, a pair of dividing walls 80/85 are used to define a loop around the plenum 500 which may contain circulating gas and passes through only one of the dividing walls (here 80). Generally speaking, the dividing walls 80/85 should connect between the first wall 740 and second wall 730 of the plenum. In an exemplary embodiment, dividing wall 80 is perpendicular to dividing wall 85. Even more preferably, dividing wall 80 is arranged horizontally and contains the fan(s) while dividing wall 85 is connected to the end of dividing wall 80 but is arranged vertically and does not contain a fan. Although fans are only shown within the dividing wall 80, they could instead be placed within the dividing wall 85, or only within the dividing wall 85 with no fans placed within dividing wall 80. For exemplary airflow, it has been discovered that placing the first fan 75 near the center of the display assembly and the second fan 77 near the perimeter of the display assembly, causes a pair of circulating gas loops 501 and 510 respectfully.


A plurality of input/output electrical connections 25 are preferably placed at the top of the display assembly 201 and underneath a sloped rain catcher 705. Also, a pair of mounting pins 50 and 51 are arranged at the top of the display assembly 201. A plurality of latches 120, 122, 125 are preferably arranged at the bottom of the display assembly 201, although shown with three latches embodiments can be practiced with one or two latches only. Also shown in this figure are the attachment brackets 900 and 910 for gas springs 850 or other supporting resistive elements.



FIG. 9 is a detailed perspective view of Detail 9 showing the post. Here, the details of the post 51 may be observed. In this embodiment, a cylinder travels horizontally and is divided by two locating walls 53 (closest to the perimeter of the display assembly 201) and 54 (closest to the center of the display assembly 201). The cylinder can then be identified by the mounting portion 55 (located between walls 53/54) and the interior portion 52 (starting at the wall 54 and travelling towards the center of the module 500).



FIG. 10 is a detailed perspective view of the corresponding hook 450 on the second display assembly 401. A pair of mounting hooks 450 are preferably placed at the top of the second display assembly 401 and correspond to the mounting posts 50 and 51 respectively. Preferably, the hook 450 would wrap around the circumference of the mounting portions 55, where the hook 300 is stabilized between the walls 54 and 53.
