[0013] Common reference numbers are used throughout the drawings and detailed description to denote the same or similar elements. The present disclosure will become more apparent from the following detailed description taken in conjunction with the accompanying drawings, in which: DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0011] The following disclosure provides many different embodiments or examples for implementing different features of the provided subject matter. Specific examples of components and arrangements are described herein. Of course, these are merely examples and are not intended to be limiting. The present disclosure may repeat reference numbers and / or letters in various examples. This repetition is for simplicity and clarity and does not in itself dictate a relationship between the various embodiments and / or configurations described.

[0012] The embodiments of the present disclosure are described in detail below. It should be understood, however, that the present disclosure provides many applicable concepts that can be embodied in a wide variety of specific contexts. The specific embodiments described are merely illustrative and are not intended to limit the scope of the present disclosure.

[0013] 1 is a cross-sectional view of an exemplary electronic display assembly 1 according to one embodiment of the present disclosure. In some embodiments, the electronic display assembly 1 may include a case 10, a heat exchanger 11, a display module 12, a transparent lid 13, an internal flow generator 14, and an external flow generator 15.

[0014] The case (or housing) 10 may have an inlet 10i, an outlet 10o opposite the inlet 10i, and a central portion 10c connecting the inlet 10i and the outlet 10o. The central portion 10c may include or define a central passageway c6 that connects or fluidly communicates with an external environment via the inlet 10i and the outlet 10o. For example, an external or ambient air flow may enter the central portion 10c through the inlet 10i and exit the central portion 10c through the outlet 10o.

[0015] The central portion 10c of the case 10 may have a side surface 101 and a side surface 102 opposite the side surface 101. A space may be defined in each of the side surfaces 101 and 102.

[0016] For example, the transparent lid 13 and case 10 can define a space on side 101 for housing a set of components including, but not limited to, a heat exchanger 11, a display module 12, and an internal flow generator 14. Similarly, another transparent lid and case 10 can define a space on side 102 for housing another heat exchanger, another display module, and another internal flow generator. The electronic display assembly 1 can include a dual-sided display. Because the components on both sides are similar, for the sake of brevity and clarity, only the components on side 101 will be referenced in the figures and described in detail.

[0017] The heat exchanger 11 may be disposed in a space defined by the case 10 on the side 101. In some embodiments, the heat exchanger 11 may be attached or fixed to the case 10. In some embodiments, the heat exchanger 11 may be attached to the case 10 via one or more sealing components 11r1 and 11r2. In some embodiments, the sealing components 11r1 and 11r2 may include a rubber gasket or an O-ring. In some embodiments, the sealing components 11r1 and 11r2 may be disposed between the central portion 10c and the heat exchanger 11.

[0018] In some embodiments, the heat exchanger 11 may be configured to function as a support substrate for the display module 12. For example, the heat exchanger 11 may provide mechanical support to the display module 12. For example, the heat exchanger 11 may be in direct contact with the display module 12 (such as the backlight layer 12c of the display module 12). For example, the display module 12 may have a front surface configured to emit light and a rear surface in direct contact with the heat exchanger 11.

[0019] For large display devices, the support substrate may significantly increase the thickness and weight of the display device. In addition, the support substrate disposed between the display module and the heat exchanger may also reduce the efficiency of heat dissipation. By providing the heat exchanger 11, which also functions as a support substrate, the thickness and weight of the display device can be reduced and the heat dissipation efficiency can be improved.

[0020] In some embodiments, the heat exchanger 11 may be thermally connected to the display module 12 and the case 10 (such as the central portion 10c). In some embodiments, the heat exchanger 11 may be integrally formed or formed in one piece. In some embodiments, the heat exchanger 11 may include an aluminum extrusion (such as an aluminum t-slot extrusion). In some embodiments, the heat exchanger 11 may include multiple channels or cells. For example, the heat exchanger 11 may include a channel c1 and a channel c4.

[0021] Channel c1 may be adjacent to and thermally connected to the display module 12. Channel c1 may be connected or in fluid communication with channels c2 and c3 (discussed in more detail below). Channels c1, c2, and c3 may define an internal heat exchange loop i1.

[0022] Channel c4 may be adjacent to or thermally connected to channel c1. Channel c4 may be adjacent to or thermally connected to central portion 10c. Channel c4 may be connected to or in fluid communication with central passage c6 of central portion 10c. Channel c4, central passage c6, and channel c5 of another heat exchanger on side 102 may define an external heat dissipation path e1. In some embodiments, external heat dissipation path e1 may be configured to dissipate heat from channel c1. In some embodiments, the flow direction of channel c1 may be opposite to the flow direction of channel c4.

[0023] The display module 12 may be disposed in a space defined by the case 10 on the side 101. In some embodiments, the display module 12 may include a display panel 12a, an optical film 12b, and a backlight layer 12c. The display panel 12a may be disposed between the optical film 12b and the transparent lid 13. The optical film 12b may be disposed between the display panel 12a and the backlight layer 12c. The backlight layer 12c may be disposed between the optical film 12b and the heat exchanger 11.

[0024] The display panel 12a may include, for example, a glass panel, a liquid crystal panel, a plastic panel, etc. The optical film 12b may include, for example, a diffuser, a reflector, a polarizer, a filter, a light guide, a lens, or other optical elements. The backlight layer 12c may include a plurality of light-emitting pixels.

[0025] In some embodiments, the display module 12 can include a channel c2 between the display panel 12a and the optical film 12b.

[0026] The transparent lid 13 may be disposed on a side surface 101 of the case 10. The transparent lid 13 may be rotatably connected to the case 10 via a pivot joint 11p. The transparent lid 13 may be removably attached to the case 10 via one or more sealing components 13r1 and 13r2. In some embodiments, the sealing components 13r1 and 13r2 may include a rubber gasket or an O-ring. In some embodiments, the sealing components 13r1 and 13r2 may be disposed between the transparent lid 13 and the case 10. In some embodiments, the sealing components 13r1 and 13r2 may be disposed between the transparent lid 13 and the display module 12. In some embodiments, the sealing components 13r1 and 13r2 may be disposed around the periphery of the display module 12.

[0027] In some embodiments, the transparent lid 13 may be configured to cover the display module 12. In some embodiments, the transparent lid 13 and the display panel 12a of the display module 12 may define a channel c3. For example, the channel c3 may be defined between the transparent lid 13 and the display panel 12a.

[0028] In some embodiments, the electronic display assembly 1 may include an internal heat exchange loop i1 on the side 101. As described above, the internal heat exchange loop i1 may be defined by one or more channels on the side 101, such as channel c1, channel c2, and channel c3. The internal heat exchange loop i1 may be configured to cool components on the side 101. In some embodiments, the internal heat exchange loop i1 may be isolated from the external environment. For example, an external air flow may not enter the internal heat exchange loop i1.

[0029] The internal flow generator 14 may be disposed in a space defined by the case 10 on the side 101. In some embodiments, the internal flow generator 14 may be disposed adjacent to the channel c1. In some embodiments, the internal flow generator 14 may be connected or in fluid communication with the channels c1, c2, and c3. In some embodiments, the internal flow generator 14 may include a fan. In some embodiments, the internal flow generator 14 may be configured to generate an internal air flow through the internal heat exchange loop i1.

[0030] Similarly, the electronic display assembly 1 may include an internal heat exchange loop i2 on the side 102. The internal heat exchange loop i2 may be defined by one or more channels on the side 102. The internal heat exchange loop i2 may be configured to cool components on the side 102. In some embodiments, the internal heat exchange loop i2 may be isolated from the external environment. For example, an external air flow may not enter the internal heat exchange loop i2.

[0031] In some embodiments, the internal heat exchange loop i2 may be isolated from the internal heat exchange loop i1. For example, the internal heat exchange loop i2 may be separate or independent from the internal heat exchange loop i1. For example, the internal heat exchange loop i2 may not be connected or fluidly conductive to the internal heat exchange loop i1. In these cases, contamination from the external environment, such as dust or moisture, does not enter the space housing the display module 12 and other electrical components, slowing down aging of the components within the space.

[0032] In some embodiments, the electronic display assembly 1 may include an external heat dissipation path e1. As described above, the external heat dissipation path e1 may be defined by a channel c4 of the heat exchanger 11 on the side 101, a channel c5 of another heat exchanger on the side 102, and a central path c6. The channels c4 and c5 may each be connected between the inlet 10i and the outlet 10o via the central path c6. The channels c4 and c5 may be connected or fluidly communicated to an external environment via the central path c6, the inlet 10i, and the outlet 10o.

[0033] The external heat dissipation path e1 may be configured to conduct heat from the internal heat exchange loop i1 and the internal heat exchange loop i2 to an external environment. For example, the external heat dissipation path e1 may be shared by the internal heat exchange loop i1 and the internal heat exchange loop i2.

[0034] In some embodiments, the external heat dissipation path e1 may be isolated from the internal heat exchange loop i1 and the internal heat exchange loop i2. For example, the external heat dissipation path e1 may be separate or independent from the internal heat exchange loop i1 and the internal heat exchange loop i2. For example, the external heat dissipation path e1 may not be connected or fluidly connected to the internal heat exchange loop i1 and the internal heat exchange loop i2.

[0035] The external flow generator 15 may be disposed adjacent to the central portion 10c of the case 10. The external flow generator 15 may be connected or in fluid communication with the channel c4, the channel c5, and the central path c6. In some embodiments, the external flow generator 15 may include a fan. In some embodiments, the external flow generator 15 may be configured to generate an external air flow through the external heat dissipation path e1.

[0036] According to some embodiments of the present disclosure, heat from the internal heat exchange loops i1 and i2 can be dissipated through a single path (i.e., the central path c6), thereby reducing the size of the electronic display assembly 1.

[0037] In addition, only one external flow generator 15 is needed and the display modules of both sides of the electronic display assembly 1 can be cooled simultaneously. The wind pressure caused by the external flow generator 15 is distributed to both channels c4 and c5. Therefore, the wind pressure on either channel c4 or channel c5 is lower than when the wind pressure caused by the external flow generator 15 is applied to only one channel.

[0038] Generally, the heat dissipation efficiency can be increased by increasing the rotation speed of the flow generator. In that case, the wind pressure and the noise caused by the wind pressure will also increase. According to some embodiments of the present disclosure, the wind pressure in the channel c4 or c5 is lower than that when only one channel is connected to the external flow generator 15. As a result, the noise caused by the wind pressure is eliminated while the heat dissipation efficiency of the electronic display assembly 1 remains unchanged.

[0039] FIG. 2 illustrates the example electronic display assembly 1 of FIG. 1 with a transparent lid 13 exposing the internal heat exchange loop i1 to the environment, according to one embodiment of the present disclosure.

[0040] In some embodiments, as shown in Fig. 1, when the transparent lid 13 is closed (or in a first position), the transparent lid 13 may be attached to the case 10 via sealing components 13r1 and 13r2. The transparent lid 13 and the sealing components 13r1 and 13r2 can isolate an internal space (such as the internal heat exchange loop i1) of the case 10 from an external environment (such as air). For example, the transparent lid 13 and the sealing components 13r1 and 13r2 can define an airtight space.

[0041] In some embodiments, as shown in FIG. 2, when the transparent lid 13 is opened (or in the second position), the internal space of the case 10 (such as the internal heat exchange loop i1) may be exposed to the external environment (such as air).

[0042] According to some embodiments of the present disclosure, the transparent lid 13 can be opened and closed, so that the internal space of the case 10 can be cleaned and maintained as needed. Therefore, the reliability of the electronic display assembly 1 can be improved.

[0043] FIG. 3 is a top view of an exemplary electronic display assembly 3, according to one embodiment of the disclosure.

[0044] The electronic display assembly 3 may include a three-sided display. For example, the electronic display assembly 3 may include a central portion 33 and display modules 30, 31, and 32. The display modules 30, 31, and 32 may be disposed on three sides of the central portion 33. The display modules 30, 31, and 32 may be disposed around the central portion 33.

[0045] Each of the display modules 30, 31, and 32 may be similar to the display module 12 of Figure 1. The electronic display assembly 3 may include other components including, but not limited to, a transparent lid, a heat exchanger, and an internal flow generator on each of three sides of the central portion 33. The other components are not shown in Figure 3 for the sake of brevity and clarity.

[0046] The electronic display assembly 3 may also include an external flow generator disposed adjacent to the central portion 33. Heat from the display modules 30, 31, and 32 may be dissipated through an external heat dissipation path defined by the central portion 33.

[0047] The number of display modules may be determined based on the size and dissipation efficiency (or other design considerations) of the electronic display assembly 3, and is not limited to this embodiment.
