[0028] Figure 1 is a schematic top view of an internal part of a display device according to an embodiment of the present application. Please refer to Figure 1 The display device 100 includes a housing 110, a display panel 120, a first baffle 130, a heat generating component 140 and a first fan F1. The housing 110 has a first side wall 111, a second side wall 112, a third side wall 113 and a fourth side wall 114. The first side wall 111 is opposite to the third side wall 113. The second side wall 112 is opposite to the fourth side wall 114, and the second side wall 112 and the fourth side wall 114 are connected between the first side wall 111 and the third side wall 113. The first side wall 111 has an air inlet I, and the second side wall 112 has an air outlet O. The third side wall 113 has a light-transmitting portion 1131 and a non-light-transmitting portion 1132 connected to each other. The display panel 120 is disposed in the housing 110 and has a display surface 121 and a back surface 122 opposite to each other. The display surface 121 faces the light-transmitting portion 1131 and forms a channel with the light-transmitting portion 1131; in other words, the display surface 121 is spaced apart from the light-transmitting portion 1131 to form a first heat dissipation space S1, and the first heat dissipation space S1 is the channel. The first baffle 130 is disposed in the housing 110. The first baffle 130 is opposite to the second side wall 112 and is located between the first side wall 111 and the back surface 122, and the first baffle 130 and the fourth side wall 114 form a second heat dissipation space S2. The first baffle 130 and the second side wall 112 form a third heat dissipation space S3. The second heat dissipation space S2 is communicated between the air inlet I and the first heat dissipation space S1, and the third heat dissipation space S3 is communicated between the first heat dissipation space S1 and the air outlet O. The heat generating component 140 is disposed in the second heat dissipation space S2. The first fan F1 is disposed in the third heat dissipation space S3 and corresponds to the air outlet O, and is adapted to draw air in the third heat dissipation space S3 out of the housing 110.

[0029] The display device 100 according to the embodiment can be an outdoor display device, in particular, the outdoor display device means that the display device 100 must meet the weatherproof specification requirements of relevant regulations such as waterproofing and heat dissipation, but in other embodiments, the display device 100 can be an indoor display device.

[0030] In the present embodiment, the display panel 120 can include a liquid crystal display panel. In detail, the liquid crystal display panel is prone to liquefaction when the temperature is too high, resulting in poor image quality. For example, when the display device 100 is placed in an outdoor environment, long-term exposure to sunlight can easily cause the temperature of the display panel 120 to be too high. However, the display device 100 of the present embodiment forms a first heat dissipation space S1 between the third side wall 113 and the display panel 120, so that the airflow A passing through the first heat dissipation space S1 can reduce the temperature of the display panel 120, thereby improving the heat dissipation efficiency of the display panel 120. Incidentally, in an embodiment, the distance G between the display panel 120 and the third side wall 113 (or the light-transmitting portion 1131) can be greater than or equal to 1 centimeter; in detail, the distance G can be determined according to the size of the display panel 120 to ensure that the first heat dissipation space S1 can pass a sufficient air flow for heat dissipation of the display panel 120. For example, in an embodiment, the size of the display panel 120 is 49.5 inches, and the distance G can be about 1 centimeter; in another embodiment, the size of the display panel 120 is 55 inches, and the distance G can be about 1.4 centimeters. However, the present application does not limit the specific value of the distance G, and the distance G between the display panel 120 and the third side wall 113 (or the light-transmitting portion 1131) can be more than 3.5 centimeters or more under the condition that the internal space of the housing 110 is sufficient and the visual effect of viewing the display panel 120 through the light-transmitting portion 1131 meets the specifications. Incidentally, the display device 100 of the present embodiment can also include a backlight module BM and a back plate P, wherein the backlight module BM is arranged opposite to the back surface 122, and the back plate P is fixed to a side of the backlight module BM opposite to the display panel 120, so that the display panel 120, the backlight module BM and the back plate P form a display assembly DU. In an embodiment, the display assembly DU can be a self-luminous display assembly, and the display assembly DU can at least omit the backlight module BM. The aforementioned self-luminous display assembly includes, for example, a light-emitting diode display assembly, an organic light-emitting diode display assembly, a micro light-emitting diode display assembly, or a quantum dot display assembly, and the present application does not limit this.

[0031] In this embodiment, the first baffle 130 is fixed to the display assembly DU and the first sidewall 111, for example, to separate the second heat dissipation space S2 and the third heat dissipation space S3, i.e. the second heat dissipation space S2 and the third heat dissipation space S3 are not communicated. Specifically, the first baffle 130, the first sidewall 111, the fourth sidewall 114 and the display panel 120 (or the display assembly DU) surround the second heat dissipation space S2, and the first baffle 130, the first sidewall 111, the second sidewall 112 and the third sidewall 113 surround the third heat dissipation space S3. Further, the second heat dissipation space S2 is communicated with the air inlet I, so that the airflow outside the housing 110 can flow in; and the third heat dissipation space S3 is communicated with the air outlet O, so that the airflow inside the housing 110 can flow out. In this embodiment, the first baffle 130 can be close to the second sidewall 112 and away from the fourth sidewall 114. In this way, the volume of the third heat dissipation space S3 is smaller than that of the second heat dissipation space S2, so that the hot air in the third heat dissipation space S3 can be extracted by the first fan F1 more quickly.

[0032] Figure 2 is Figure 1 A cross-sectional view along the section line A1-A1. Please refer to Figure 1 and Figure 2 When the first fan F1 is started, the air in the third heat dissipation space S3 is discharged to the outside of the housing 110, so as to generate the airflow, and the air flows in from the air inlet I, i.e. the airflow A sequentially flows through the second heat dissipation space S2, the first heat dissipation space S1 and the third heat dissipation space S3. In this embodiment, the number of the first fan F1 includes a plurality of, and the first fan F1 is arranged along the direction D1. The direction D1 points from the top T of the display panel 120 to the bottom B of the display panel 120. Therefore, when the airflow A passes through the first heat dissipation space S1, it can flow through the entire display panel 120, thereby further improving the heat dissipation efficiency of the display panel 120. In detail, the display panel 120 can have a rectangular shape and has a long side L1 and a short side L2 connected, wherein the long side L1 extends along the direction D1, and the first fan F1 can be arranged along the long side L1. It should be noted that the number of the first fan F1 in this embodiment is seven, but in other embodiments, the number and specifications of the first fan F1 can be determined according to the size of the display panel 120. For example, in another embodiment, the size of the display panel 120 can be between 49.5 inches and 55 inches, and the number of the first fan F1 can be 6-8, and the airflow of each first fan F1 can be about 190 CFM. However, the number and specifications of the first fan F1 are not limited in the present application.

[0033] Figure 3 is Figure 1 A block diagram of the display panel, the power output module and the processing module of the display device. Please refer to Figure 1 and Figure 3The heat-generating component 140, for example, is a part that generates a large amount of heat when the display device 100 is in operation. For example, in the present embodiment, the heat-generating component 140 can include a power output module 141 and a processing module 142. The power output module 141 and the processing module 142 are respectively electrically connected to the display panel 120. In detail, the display device 100 of the present embodiment can be applied to a charging pile, and thus the power output module 141 can be electrically connected to a charging gun to charge an external device. On the other hand, the processing module 142, for example, includes a computing component, a storage component, a communication component, and the like to provide functions of transmitting and processing data. In an embodiment, the computing component can include a central processing unit or a microprocessor, but the present application is not limited thereto. It can be understood that, in other embodiments, the heat-generating component 140 is not limited to the power output module 141 and the processing module 142.

[0034] Figure 4 is a perspective view of the display device of Figure 1 . Please continue to refer to Figure 1 , in the present embodiment, the materials of the first side wall 111, the second side wall 112, and the fourth side wall 114 of the housing 110 can include metal or plastic. In the air inlet direction D2 from the first side wall 111 to the third side wall 113, the air inlet I, for example, overlaps the heat-generating component 140. Thus, the air flow through the heat-generating component 140 can be increased to further improve the heat dissipation efficiency of the heat-generating component 140. For example, in the present embodiment, the air inlet I can overlap the power output module 141 and the processing module 142 in the air inlet direction D2. However, in an embodiment, the air inlet I can overlap the power output module 141 in the air inlet direction D2 and be misaligned with the processing module 142. In another embodiment, the air inlet I can be provided with a fan (not shown in the figure), which can suck air outside the housing 110 into the housing 110, thereby further improving the heat dissipation efficiency of the display device 100. Incidentally, please refer to Figure 4 , the air inlet I of the first side wall 111 can be in a dot pattern; similarly, the air outlet O of the second side wall 112 can be in a dot pattern, but the present application is not limited to the shape of the air inlet I and the air outlet O.

[0035] Figure 5 is another view of the display device of Figure 4 . Please refer to Figure 1 and Figure 5 , the light-transmitting portion 1131, for example, overlaps the display panel 120 in the air inlet direction D2, and the non-light-transmitting portion 1132 can surround the light-transmitting portion 1131. In the present embodiment, the material of the light-transmitting portion 1131 of the third side wall 113 can include glass, and the material of the non-light-transmitting portion 1132 can include plastic or metal, but the present application is not limited thereto.

[0036] Compared with the prior art, the display device 100 of the embodiment forms the first heat dissipation space S1, the second heat dissipation space S2 and the third heat dissipation space S3 via the housing 110, the display panel 120 and the first baffle 130. In detail, the airflow passing through the first heat dissipation space S1 can reduce the temperature of the display panel 120, and the airflow passing through the second heat dissipation space S2 can reduce the temperature of the heat generating component 140. On the other hand, the fan can send the airflow passing through the first heat dissipation space S1 and the second heat dissipation space S2 to (suck or blow) the third heat dissipation space S3, and then suck the airflow of the third heat dissipation space S3 out of the housing 110. Therefore, the display device 100 of the embodiment can effectively reduce the temperature of the display panel 120 and the heat generating component 140, thereby improving the heat dissipation efficiency. The fan mentioned above is, for example, the first fan F1 located at the air outlet O, and in other embodiments, the fan mentioned above can include a fan located at the air inlet I (not shown in the figure).

[0037] For example, in a sunny environment with an ambient temperature of 50°C, about 75% of the area of the display surface of the existing display device has a temperature exceeding 70°C, and at least more than 35% of the area of the display surface has a temperature exceeding 80°C. Further, when the temperature of the display surface exceeds 80°C, obvious ripples occur on the screen, resulting in a significant deterioration of image quality. However, when the display device 100 of an embodiment of the present application is placed in a sunny environment with an ambient temperature of 50°C, the temperature of all areas of the display surface 121 is lower than 70°C. Therefore, compared with the existing display device, the display device 100 of an embodiment of the present application can significantly improve the problem of overheating of the display panel 120, thereby improving the image quality.

[0038] Please continue to refer to Figure 1 . By the way, the display device 100 of the embodiment further includes, for example, a light reduction layer 150, which is arranged on the light-transmitting portion 1131. In this way, the amount of light irradiated to the display panel 120 can be further reduced, thereby further preventing the temperature of the display panel 120 from being too high. The light reduction layer 150 is arranged, for example, on the surface of the light-transmitting portion 1131 facing the display panel 120, but in other embodiments, the light reduction layer 150 can be arranged on the surface of the light-transmitting portion 1131 facing away from the display panel 120. In addition, the light reduction layer 150 of the embodiment is fixed to the light-transmitting portion 1131 in a pasting manner, but the present application does not limit the fixing manner of the light reduction layer 150.

[0039] Figure 6 is a top view of the display device of another embodiment of the present application. Figure 7 is Figure 6 is a schematic view of the first fixing member connecting the third baffle and the third side wall of Figure 1embodiment, the display panel 120, the backlight module BM, and the back plate P of the display device 100a form a display unit DU, and only the differences will be described below. Please refer to Figure 6 The display device 100a can further include a second baffle 160, a third baffle 170, and a fourth baffle 180 disposed in the housing 110. In detail, the second baffle 160, the third baffle 170, and the fourth baffle 180 can be combined to form a frame F. The display unit DU is disposed in the frame F, and the frame F has an opening OP exposing the display surface 121. The second baffle 160 is disposed opposite to the back surface 122. The third baffle 170 and the fourth baffle 180 are located beside the opposite two side surfaces 123 of the display panel 120, and are respectively connected between the second baffle 160 and the third side wall 113. The third baffle 170 and the third side wall 113 have a gap therebetween; in other words, the third baffle 170 and the third side wall 113 are spaced apart to form a ventilation opening V1, and the ventilation opening V1 is the gap. The fourth baffle 180 and the third side wall 113 have a gap therebetween; in other words, the fourth baffle 180 and the third side wall 113 are spaced apart to form a ventilation opening V2, and the ventilation opening V2 is the gap. The ventilation openings V1 and V2 are communicated to the first heat dissipation space S1, and are located on opposite sides of the first heat dissipation space S1. In detail, the second baffle 160 and the third baffle 170 can further separate the first heat dissipation space S1 and the second heat dissipation space S2, and the fourth baffle 180 can further separate the first heat dissipation space S1 and the third heat dissipation space S3. In this way, the airflow A can be more concentrated through the first heat dissipation space S1, and the air exhaust efficiency of the first fan F1 on the third heat dissipation space S3 can be improved, thereby further improving the heat dissipation efficiency of the display device 100a.

[0040] More specifically, the ventilation opening V2 of the fourth baffle 180 can be communicated to the third heat dissipation space S3, so that the airflow A can enter the first heat dissipation space S1 from the second heat dissipation space S2 through the ventilation opening V1, enter the third heat dissipation space S3 from the first heat dissipation space S1 through the ventilation opening V2, and then exit the housing 110 from the air outlet O. Please refer to Figure 6 and Figure 7The display device 100a may further include a plurality of first fixing members SC1 and a plurality of second fixing members SC2, wherein the first fixing members SC1 and the second fixing members SC2 may be collectively referred to as fixing members. The first fixing members SC1 connect the frame F and the third sidewall 113; specifically, the first fixing members SC1 connect the third baffle 170 of the frame F and the third sidewall 113, and each first fixing member SC1 is spaced apart from each other to form a vent V1. The second fixing members SC2 connect the frame F and the third sidewall 113; more specifically, the second fixing members SC2 connect the fourth baffle 180 of the frame F and the third sidewall 113. Each second fixing member SC2 is spaced apart from each other to form a vent V2. In this embodiment, the first fixing members SC1 and the second fixing members SC2 may include screws. Specifically, the first fixing members SC1 may be locked between the third baffle 170 and the third sidewall 113, and are spaced apart from each other in direction D1 to form a vent V1. On the other hand, the second fixing members SC2 are arranged in the same way. Figure 7 The first fixing member SC1 and the second fixing member SC2 can be locked between the fourth baffle plate 180 and the third sidewall 113, and are spaced apart from each other in direction D1 to form a vent V2. Therefore, the airflow A will be disturbed by the screw SC when passing through the vents V1 and V2, forming turbulence, which further improves the heat dissipation efficiency of the airflow A for the display panel 120. Incidentally, please refer to [reference needed]. Figure 6 The heat-generating component 140 and the first baffle 130 are, for example, fixed to the second baffle 160, but the present invention does not impose further limitations on this. In this embodiment, the diameter (i.e., the spacing G) of the channel (i.e., the first heat dissipation space S1) can be larger than the diameters G1 and G2 of the two gaps, respectively. Thus, the flow velocity of the airflow A changes when passing through the diameter, thereby disrupting the flow direction of the airflow A and forming turbulence, thereby further improving the heat dissipation efficiency of the airflow A on the display panel 120.

[0041] Figure 8 This is a top view of the interior of a display device according to another embodiment of the present invention. Figure 9 yes Figure 8 A schematic view along section line A2-A2. The structure and advantages of the display device 100b in this embodiment are similar to those of... Figure 1 In this embodiment, the display panel 120, backlight module BM, and backplate P of the display device 100b form a display assembly DU. The differences will be described below. Please refer to [reference needed]. Figure 8, the display device 100b further comprises a baffle (also referred to as a second baffle) 190 and a second fan F2. The baffle 190 is connected between the first baffle 130 and the second side wall 112. The second fan F2 is arranged on the baffle 190 and is in communication with the first heat dissipation space S1 and the third heat dissipation space S3. The second fan F2 is adapted to draw air in the first heat dissipation space S1 to the third heat dissipation space S3. In this way, the speed of the airflow A flowing through the first heat dissipation space S1, the second heat dissipation space S2 and the third heat dissipation space S3 can be further increased, so that the hot air is discharged out of the housing 110 more quickly, thereby further improving the heat dissipation efficiency of the display device 100b. In detail, the baffle 190 can have a vent (also referred to as a setting hole) V3 (also shown in Figure 9 ) in communication with the second heat dissipation space S2 and the third heat dissipation space S3, and the second fan F2 can be arranged on the vent V3. Incidentally, in an embodiment, the first fan F1 and the second fan F2 can be connected via a flow guide pipe (not shown in the figure) to further increase the speed of the first fan F1 and the second fan F2 in drawing hot air out of the housing 110.

[0042] Please refer to Figure 8 and Figure 9 , in the present embodiment, the number of the second fans F2 includes a plurality of, for example, and the second fans F2 are arranged along the direction D1. In this way, it can be ensured that the airflow A generated by the second fans F2 can flow through the entire display surface 121 when passing through the first heat dissipation space S1, thereby further improving the heat dissipation efficiency of the display panel 120. It can be understood that the number and specifications of the second fans F2 are substantially the same as those of the first fan F1, and therefore the related description is omitted here.

Please refer to Figure 11 , it can be understood that the baffle 190 can be arranged in the display device 100a of Figure 6 . Further, the first baffle 130 is connected to the frame F, and in more detail, the first baffle 130 is connected to the second baffle 160 of the frame F. In addition, the baffle 190 is connected between the first baffle 130 and the second side wall 112 of the frame F. In an embodiment, the baffle 190 can be connected between the frame F and the second side wall 112; further, the baffle 190 can be connected between the fourth baffle 180 of the frame F and the second side wall 112.
