[0101] To address the issue of poor heat dissipation in display devices mounted on a display image, this disclosure provides a display device that improves heat dissipation.

[0102] Please see Figure 1 and Figure 2 , Figure 1 This is a schematic diagram of the structure of a display device according to some embodiments of the present disclosure, and Figure 2 This is a structural side view of a display device according to some embodiments of the present disclosure. For heat dissipation purposes, some embodiments of the present disclosure provide a display device 10 including a fixed structure 11, a first rotating shaft 12 connected to the fixed structure 11, and a first display module 13 connected to the first rotating shaft 12.

[0103] First, the first embodiment disclosed herein provides a display device 10 with a single-sided display element. In the X direction, the fixing structure 11 of the first embodiment includes a first side and a second side opposite to the first side, and the fixing structure 11 further includes a bearing surface and a fixing surface opposite to the bearing surface. Further, the fixing structure 11 includes a first heat sink 112, and the first heat sink 112 of the fixing structure 11 is disposed between the first side and the second side of the fixing structure 11. Specifically, the first heat sink 112 includes a first heat dissipation side 1122, a second heat dissipation side 1124, a first bearing surface 1126, and a first fixing surface 1128. In the X direction, the first heat dissipation side 1122 and the second heat dissipation side 1124 of the first heat sink 112 are opposite each other; the aforementioned first side is the first heat dissipation side 1122 in this embodiment, and the second side is the second heat dissipation side 1124. With the first rotating shaft 12 as a reference, the first heat dissipation side 1122 of the first heat sink 112 is closer to the first rotating shaft 12, while the second heat dissipation side 1124 of the first heat sink 112 is farther away from the first rotating shaft 12. In the Z direction, the first bearing surface 1126 and the first fixing surface 1128 are arranged opposite to each other, that is, the first bearing surface 1126 faces the first display module 13, while the first fixing surface 1128 faces the display device fixing point TP (e.g., ...). Figure 2 Furthermore, the first heat dissipation side 1122 is adjacent to one end of the first bearing surface 1126 and one end of the first fixing surface 1128, and the second heat dissipation side 1124 is adjacent to the other end of the first bearing surface 1126 and the other end of the first fixing surface 1128. In other words, the first bearing surface 1126 and the first fixing surface 1128 are located between the first heat dissipation side 1122 and the second heat dissipation side 1124.

[0104] In addition, such as Figure 2 As shown, the fixing structure 11 allows the display device 10 to be fixed to the display device fixing point TP, such as a ceiling or vehicle roof. Specifically, the fixing surface of the fixing structure 11 allows the display device 10 to be fixed to the display device fixing point TP, such as a ceiling or vehicle roof. More specifically, the first fixing surface 1128 of the first heat sink 112 allows the display device 10 to be fixed to the display device fixing point TP. It is understood that in this embodiment, the bearing surface of the fixing structure 11 includes the first bearing surface 1126 of the first heat sink 112 (e.g., ...). Figure 1 ), and the fixing surface of the fixing structure 11 includes the first fixing surface 1128 of the first heat sink 112 (e.g. Figure 1 ).

[0105] Next, please refer to Figure 3A , Figure 3A According to some embodiments disclosed herein Figure 1The enlarged cross-sectional view is shown in section line 3-3. The first rotating shaft 12 includes a rotating shaft body 122, a first fixing element 124 connected to one end of the rotating shaft body 122, and a second fixing element 126 opposite to the first fixing element 124 and connected to the other end of the rotating shaft body 122. The first fixing element 124 is disposed on the first bearing surface 1126 of the first heat dissipation side 1122. Specifically, the first fixing element 124 is disposed adjacent to the first bearing surface 1126 of the first heat dissipation side 1122.

[0106] The first display module 13 includes a first display area 132 and a first peripheral area 134 adjacent to the first display area 132. A second fixing element 126 is disposed in the first peripheral area 134 of the first display module 13. By connecting the first display module 13 and the first heat sink 112 with the first rotating shaft 12, the heat generated by the first display module 13 can be transferred to the first heat sink 112 through the first rotating shaft 12 to achieve the effect of heat dissipation.

[0107] Next, please refer to Figure 3A and Figure 3B , Figure 3B According to some embodiments disclosed herein Figure 3A The enlarged cross-sectional view of the dashed box FR2 is shown. The first display module 13 further includes a heat dissipation structure 14. This includes a light guide plate 141 disposed in the first display area 132, a light source 142 disposed in the first display area 132 and adjacent to the light guide plate 141, a substrate 143 disposed in the first peripheral area 134 and adjacent to the light source 142, a heat-conducting element 144 disposed in the first peripheral area 134 and adjacent to the substrate 143, and a heat dissipation element 145 disposed in the first peripheral area 134 and adjacent to the heat-conducting element 144. In some embodiments, the light source 142 is a light-emitting diode (LED). In some embodiments, the substrate 143 is made of metal, such as aluminum. Notably, aluminum has a high thermal conductivity (e.g., greater than 200 W / mk), which can improve the thermal conductivity of the substrate 143, thereby improving the heat dissipation efficiency of the heat dissipation structure 14.

[0108] In the Z direction, the light guide plate 141 includes a light incident surface 1412 and a back light surface (not shown) relative to the light incident surface 1412. With reference to the substrate 143, the light incident surface 1412 of the light guide plate 141 is closer to the substrate 143 relative to the back light surface of the light guide plate 141, while the back light surface of the light guide plate 141 is farther from the substrate 143 relative to the light incident surface 1412. The light source 142 includes a light emitting side 1422 and a back side 1424 relative to the light emitting side 1422, and the light emitting side 1422 of the light source 142 faces the light incident surface 1412 of the light guide plate 141. The substrate 143 includes a first heat-conducting side 1432 and a first heat-dissipating side 1434 relative to the first heat-conducting side 1432, and the first heat-conducting side 1432 of the substrate 143 is connected to the back side 1424 of the light source 142. The heat-conducting element 144 includes a second heat-conducting side 1442 and a second heat-dissipating side 1444 opposite to the second heat-conducting side 1442, and the second heat-conducting side 1442 of the heat-conducting element 144 is connected to the first heat-dissipating side 1434 of the substrate 143. The heat-dissipating element 145 includes a third heat-conducting side 1452 and a fourth heat-dissipating side 1454 opposite to the third heat-conducting side 1452, and the third heat-conducting side 1452 of the heat-dissipating element 145 is connected to the second heat-dissipating side 1444 of the heat-conducting element 144. Since the light source 142 is a heat-generating element, by connecting the first heat-conducting side 1432 of the substrate 143 to the light source 142 for heat conduction, and by connecting the first heat-dissipating side 1434 of the substrate 143 to the heat-conducting element 144 and the heat-conducting element 144 to the heat-dissipating element 145, heat is exchanged with the ambient air through the first rotating shaft 12 and the first heat sink 112 to achieve the effect of heat dissipation.

[0109] Furthermore, such as Figure 3A As shown, the second fixing element 126 of the first rotating shaft 12 is disposed on the fourth heat dissipation side 1454 of the heat dissipation element 145. In this way, heat exchange with the ambient air is achieved through the heat dissipation element 145 and the first heat sink 112 to achieve the effect of heat dissipation. In addition, when the display device mounting point TP (e.g., the roof of a car) is metal, the metal of the display device mounting point TP can also achieve the effect of heat conduction to promote the effect of heat dissipation.

[0110] Furthermore, returning to such Figure 1 As shown, in some embodiments, when the size of the first display module 13 increases, and the display device is fixed at TP (e.g., as shown in the figure), Figure 2 The space is sufficient, and the number of first rotating shafts 12 can be two or more. For example, multiple first rotating shafts 12 can be arranged along the Y direction between the fixed structure 11 and the first display module 13. Increasing the number of first rotating shafts 12 can enhance the heat conduction effect, enabling the heat generated by the first display module 13 to be transferred to the first heat sink 112 through multiple first rotating shafts 12 to achieve the heat dissipation effect.

[0111] Next, through Figure 1 , Figure 4A and Figure 4B The features of the first embodiment will be described below. Figure 4A and Figure 4B This is a structural perspective view of the control module of a display device according to some embodiments of the present disclosure at different setup stages.

[0112] like Figure 1 As shown, in the first embodiment, the display device 10 further includes a control module 15 disposed on the first bearing surface 1126 of the first heat sink 112, and the control module 15 includes a system board 151, a light source driver board 152, a signal line 153, and a signal component 154. The following describes... Figure 4A and Figure 4B To illustrate the structure of the control module 15 of the display device 10 at different stages.

[0113] like Figure 1 As shown, the system board 151 is disposed on the first bearing surface 1126 of the first heat sink 112 (e.g., Figure 1 On the system board 151, the light source driver board 152 is disposed on the first bearing surface 1126 of the first heat sink 112 and spaced apart from the system board 151 in the Y direction. The signal component 154 is disposed between the first side and the second side of the fixing structure 11. That is, the signal component 154 is disposed between the first heat dissipation side 1122 and the second heat dissipation side 1124. Furthermore, in the Y direction, the signal component 154 is located between the system board 151 and the light source driver board 152. The signal line 153 connects the system board 151 and the signal component 154. Further, the signal component 154 includes a loading element 1541, a control board 1542, a first printed circuit board 1543, an adapter board 1544, and a second printed circuit board 1545.

[0114] According to Figure 1 The dashed box FR1 is drawn as follows Figure 4A As shown, the control board 1542 is mounted on the loading element 1541, and the loading element 1541 is mounted on the first heat sink 112 of the fixing structure 11 via a locking element (e.g., ...). Figure 1 The first printed circuit board 1543 is disposed on the control board 1542. The first printed circuit board 1543 is electrically connected to the control board 1542 and electrically connected to the system board 151 via signal line 153. Additionally, in Figure 4A In this circuit, the number of first printed circuit boards 1543 is one, but depending on the requirements, there may be two or more first printed circuit boards 1543.

[0115] According to Figure 1 The dashed box FR1 is drawn as follows Figure 4BAs shown, an adapter board 1544 is disposed on a first printed circuit board 1543 and a control board 1542. In some embodiments, the adapter board 1544 includes a Complex Programmable Logic Device (CPLD) adapter board. Further, a second printed circuit board 1545 is connected to the adapter board 1544. Specifically, in the X direction, the adapter board 1544 includes a first side SD1 near a first side edge (i.e., a first heat dissipation side 1122) of the fixing structure 11 and a second side SD2 opposite to the first side SD1. In some embodiments, the first side SD1 of the adapter board 1544 is parallel to the first side edge of the fixing structure 11. And, in the X direction, the second printed circuit board 1545 includes a first end ED1 and a second end ED2 opposite to the first end ED1. The first end ED1 of the second printed circuit board 1545 is connected to the first display module 13, and the second end ED2 of the second printed circuit board 1545 is connected to the first side SD1 of the adapter board 1544. In addition, in Figure 4B In this circuit, the number of second printed circuit boards 1545 is one, but depending on the requirements, there may be two or more second printed circuit boards 1545.

[0116] in accordance with Figures 4A to 4B It can be seen that the control module 15 is mounted on the first bearing surface 1126 of the first heat sink 112, thereby allowing the heat generated by the control module 15 during operation to be dissipated through the first heat sink 112 (e.g., ...). Figure 1 It achieves the effect of heat dissipation by exchanging heat with the ambient air.

[0117] Furthermore, since the first embodiment is a display device 10 with a single-sided display element, and in the side view of the first embodiment, the signal component 154 can overlap with the system board 151 and the light source driving board 152 (e.g., as shown in the figure). Figure 2 Therefore, the space and area occupied by the display device 10 can be saved.

[0118] Further, please refer to Figure 5 , Figure 5 This is a schematic diagram of the structure of a hinge element of a display device according to some embodiments of the present disclosure. The display device 10 of the first embodiment further includes a hinge element 16. The hinge element 16 includes a first hinge portion 162, a second hinge portion 164, a locking hole 166, and an opening 168. (As shown...) Figure 1 As shown, the hinge element 16 is disposed between the first heat sink 112 and the first peripheral area 134 of the first display module 13. Figure 5The hinge element 16 includes a first hinge portion 162 and a second hinge portion 164 opposite to the first hinge portion 162. The first hinge portion 162 of the hinge element 16 is disposed on the bearing surface (first bearing surface 1126 of the first heat sink 112) adjacent to the first side of the fixed structure 11, and the second hinge portion 164 of the hinge element 16 is disposed in the first peripheral area 134 of the first display module 13 (e.g., Figure 1 Specifically, the first hinge portion 162 includes a rotating portion and a first connecting portion, and the second hinge portion 164 includes a hinge body and a second connecting portion. The first connecting portion of the first hinge portion 162 is disposed on the first bearing surface 1126 of the first heat sink 112, and the second connecting portion of the second hinge portion 164 is disposed on the first peripheral area 134 of the first display module 13. The hinge body and the rotating portion engage with each other, and one side of the rotating portion includes a locking hole 166. The location of the locking hole 166 depends on whether it is convenient to install locking elements (such as screws or bolts), for example, with Figure 5 The embodiment described below is an example in which the mounting hole 166 is disposed on a side close to the light source driver board 152. Features of the mounting hole 166 will be described later in the embodiments (e.g., Figure 6 More detailed explanation will follow. Furthermore, by locking the corresponding hinge element 16 into the locking hole 166 of the locking element, the first hinge part 162 and the second hinge part 164 are fixed together, and the first display module 13 can rotate with the display device fixing point TP as a reference, so that the display device 20 can achieve the effect of different display angles.

[0119] The hinge element 16 includes an opening 168, and the first end ED1 of the second printed circuit board 1545 passes through the opening 168. Specifically, the opening 168 is located in the rotating portion of the first hinge portion 162. The opening 168 of the hinge element 16 facilitates the mounting of the second printed circuit board 1545 and also prevents the second printed circuit board 1545 from becoming too long, which could lead to signal attenuation.

[0120] Furthermore, the following is through Figure 6 , Figure 7 and Figures 8A to 8D The second embodiment will now be described. Figure 6 This is a schematic diagram of the structure of a display device according to some embodiments of the present disclosure. Figure 7 Based on this disclosure Figure 6 A structural side view of a display device according to some embodiments, and Figures 8A to 8D Based on this disclosure Figure 6 The following are structural perspective views of the control module of the display device in some embodiments at different setup stages. The display device 20 of the second embodiment can provide a double-sided display device 20. In other words, the display device 20 of the second embodiment is a double-sided display device including a first display module 13 and a second display module 23.

[0121] like Figure 6 and Figure 7 As shown, the fixing structure 11 of the second embodiment further includes a second heat sink 212, a second rotating shaft 22 connected to the second heat sink 212, and a second display module 23 connected to the second rotating shaft 22. The second heat sink 212 includes a third heat dissipation side 2122, a fourth heat dissipation side 2124, a second bearing surface 2126, and a second fixing surface 2128. In the X direction, the third heat dissipation side 2122 of the second heat sink 212 is opposite to the fourth heat dissipation side 2122. In this embodiment, the first side of the fixing structure 11 is the first heat dissipation side 1122 of the first heat sink 112, and the second side of the fixing structure 11 is the third heat dissipation side 2122 of the second heat sink 212. With the second rotating shaft 22 as a reference, the third heat dissipation side 2122 of the second heat sink 212 is closer to the second rotating shaft 22, while the fourth heat dissipation side 2124 of the second heat sink 212 is farther away from the second rotating shaft 22. In the Z direction, the second bearing surface 2126 and the second fixing surface 2128 are disposed opposite to each other, that is, the second bearing surface 2126 faces the second display module 23, while the second fixing surface 2128 faces the display device mounting point TP. Furthermore, the third heat dissipation side 2122 is adjacent to one end of the second bearing surface 2126 and the second fixing surface 2128, and the fourth heat dissipation side 2124 is adjacent to the other end of the second bearing surface 2126 and the second fixing surface 2128. Similarly, the second fixing surface 2128 of the second heat sink 212 can be connected to the display device mounting point TP via a locking element.

[0122] Additionally, it is understood that in the second embodiment, the bearing surface of the fixing structure 11 includes the first bearing surface 1126 of the first heat sink 112 and the second bearing surface 2126 of the second heat sink 212, and the fixing surface of the fixing structure 11 includes the first fixing surface 1128 of the first heat sink 112 and the second fixing surface 2128 of the second heat sink 212.

[0123] like Figure 6 and Figure 7 As shown, the second rotating shaft 22 includes a rotating shaft body 222, a third fixing element 224 connected to one end of the rotating shaft body 222, and a fourth fixing element 226 connected to the other end of the rotating shaft body 222. The third fixing element 224 of the second rotating shaft 22 is disposed on the second bearing surface 2126. Specifically, the third fixing element 224 of the second rotating shaft 22 is disposed adjacent to the second bearing surface 2126 of the second heat sink 212. The second display module 23 includes a second display area 232 (as described later). Figure 11A ) and the second peripheral area 234 adjacent to the second display area 232 (as described later) Figure 11AThe fourth fixing element 226 of the second rotating shaft 22 is disposed in the second peripheral area 234 of the second display module 23. Similarly, by connecting the second rotating shaft 22 to the second display module 23 and the second heat sink 212, the heat from the second display module 23 can be transferred to the second heat sink 212 through the second rotating shaft 22 to achieve the effect of heat dissipation.

[0124] Similarly, increasing the number of second hinges 22 can enhance the heat conduction effect, enabling the heat generated by the second display module 23 to be transferred to the second heat sink 212 through multiple second hinges 22 to achieve the heat dissipation effect.

[0125] Furthermore, although not shown separately, the second display module 23 also includes a heat dissipation structure, and the heat dissipation structure of the second display module 23 is similar to the heat dissipation structure 14 of the aforementioned first display module 13 (e.g., Figure 3A The characteristics are the same as those of the other two, so they will not be repeated here.

[0126] Furthermore, such as Figure 6 As shown, in order to provide images to the first display module 13 and the second display module 23, the display device 10 of the second embodiment also includes a control module 25 disposed on the bearing surface of the fixed structure 11.

[0127] The control module 15 in the second embodiment includes a system board 251, a light source driver board 252, signal lines 253, and a signal component 254, wherein the signal component 254 includes a control board 2542, and first printed circuit boards 2543A and 2543B (e.g., Figure 8B ), second printed circuit board 2545A, 2545B (e.g. Figure 8D ) and third printed circuit boards 2546A, 2546B (such as Figure 8D Additionally, in the second embodiment, the fixing structure 11 further includes a connecting element 214 (such as...). Figure 6 The connecting element 214 is configured to support the control module 25. In addition to providing a place for the control module 25 to avoid the problem of the control module 25 having nowhere to be fixed, the connecting element 214 also creates a gap between the control module 25 and the system board 251 and the light source driver board 252, allowing space for heat to be dissipated better.

[0128] Furthermore, the control module 25 of the second embodiment differs from the control module 15 of the first embodiment in that it comprises a first printed circuit board, a second printed circuit board, and a third printed circuit board. The following combinations... Figures 8B to 8D illustrate.

[0129] According to Figure 6 The dashed box FR3 indicates Figure 8AAs shown, the signal component 254 of the second embodiment is disposed between the first side and the second side of the fixing structure 11. Furthermore, compared to the signal component 154 of the first embodiment (such as...), Figure 4B In the second embodiment, the signal component 254 is disposed away from the first side of the fixing structure 11. Specifically, the signal component 254 is disposed between the first heat dissipation side 1122 of the first heat sink 112 and the third heat dissipation side 2122 of the second heat sink 212.

[0130] According to Figure 8A The dashed box FR4 indicates Figure 8B As shown, in the second embodiment, two first printed circuit boards 2543A and 2543B are respectively disposed at intervals on the control board 2542, and the two first printed circuit boards 2543A and 2543B are electrically connected to the control board 2542, and the two first printed circuit boards 2543A and 2543B are connected to the system board 251 (e.g., via signal lines 253) Figure 6 Electrical connection.

[0131] According to Figure 8A The dashed box FR4 indicates Figure 8C As shown, in the second embodiment, the adapter board 2544 is disposed on two first printed circuit boards 2543A and 2543B. In some embodiments, the adapter board 2544 includes a CPLD adapter board.

[0132] According to Figure 6 The dashed box FR4 indicates Figure 8DAs shown, in the second embodiment, the two second printed circuit boards 2545A and 2545B are connected to the first side SD3 of the adapter board 2544, and the two third printed circuit boards 2546A and 2546B are connected to the second side SD4 of the adapter board 2544. The two second printed circuit boards 2545A and 2545B correspond to the two first printed circuit boards 2543A and 2543B, respectively, and the two third printed circuit boards 2546A and 2546B correspond to the two first printed circuit boards 2543A and 2543B, respectively. Specifically, each second printed circuit board 2545A and 2545B includes a first terminal ED3 and ED3' and a second terminal ED4 and ED4' opposite to the first terminal ED3 and ED3'. The first terminals ED3 and ED3' of the second printed circuit boards 2545A and 2545B are connected to the first display module 13, and the second terminals ED4 and ED4' of the second printed circuit boards 2545A and 2545B are connected to the first side SD3 of the adapter board 2544. Each of the third printed circuit boards 2546A and 2546B includes a first terminal ED5 and ED5' and a second terminal ED6 and ED6' opposite to the first terminals ED5 and ED5'. The first terminals ED5 and ED5' of the third printed circuit boards 2546A and 2546B are connected to the second display module 23, and the second terminals ED6 and ED6' of the third printed circuit boards 2546A and 2546B are connected to the second side SD4 of the adapter board 1544.

[0133] Additionally, signal assembly 254 also includes a loading element 2541, and the loading element 2541 is mounted on the connecting element 214 of the fixing structure 11 via a locking element (e.g., a screw). Figure 6 On top of this, to carry and fix the signal component 254. Further, as... Figure 6 As shown, the connecting element 214 is disposed between the first heat sink 112 and the second heat sink 212, and is located below the first heat sink 112 and the second heat sink 212. The connecting element 214 is configured to cover the adapter plate 2544. In the X direction, the connecting element 214 includes a first end 2142 and a second end 2144 opposite to the first end 2142. The first end 2142 of the connecting element 214 overlaps with a portion of the first heat sink 112, and the second end 2144 of the connecting element 214 overlaps with a portion of the second heat sink 212.

[0134] By setting up first printed circuit boards 2543A and 2543B, adapter board 2544, second printed circuit boards 2545A and 2545B, and third printed circuit boards 2546A and 2546B, images can be simultaneously shared to the first display module 13 and the second display module 23. Furthermore, there is no need to set up another system board and another light source driver board, thereby reducing production costs.

[0135] Next, return to Figure 6 The display device 20 of the second embodiment shown further includes a first hinge element 26 and a second hinge element 27 adjacent to the first hinge element 26. Similarly, the first hinge element 26 and the second hinge element 27 each include a first hinge portion and a second hinge portion. The structural features and connection relationships of each first hinge portion and each second hinge portion of the first hinge element 26 and the second hinge element 27 are similar to those described above, and therefore are not shown separately and will not be described again here.

[0136] Similarly, the first hinge element 26 and the second hinge element 27 also include locking holes (e.g., locking hole 272 of the second hinge element 27). As mentioned above, the location of the locking holes depends on the convenience of installing the locking elements. Therefore, the locking hole of the first hinge element 26 (not specified separately due to angle) is located on the side away from the second hinge element 27, while the locking hole 272 of the second hinge element 27 is located on the side away from the first hinge element 26. Furthermore, by locking the corresponding hinge element (e.g., the second hinge element 27) into the locking hole (e.g., locking hole 272), the first hinge portion and the second hinge portion are fixed together, and the first display module 13 can rotate around the display device fixing point TP as a reference, so that the display device 20 can achieve different display angles.

[0137] The first hinge element 26 also includes a first opening (as described above). Figure 5 Similar to the opening 168 (therefore not shown separately), and the first end ED3 of the second printed circuit board 2545A passes through the first opening. The second hinge element 27 also includes a second opening (similar to the aforementioned...). Figure 5 Similar to the opening 168 (so it is not shown separately), and the first end ED3' of the second printed circuit board 2545B passes through the second opening. The first opening of the first hinge element 26 and the second opening of the second hinge element 27 facilitate the mounting of the second printed circuit boards 2545A and 2545B, and also prevent the second printed circuit boards 2545A and 2545B from being too long, which would weaken the signal.

[0138] Similarly, in the second display module 23 (e.g. Figure 6 A third hinge element 28 and a fourth hinge element 29 are disposed adjacently between the third printed circuit board 2546A and 2546B. The third hinge element 28 includes a third opening (as described above). Figure 5Similar to the opening 168 (so it is not shown separately), and the fourth hinge element 29 includes a fourth opening (not shown). Additionally, the first end ED5 of the third printed circuit board 2546A passes through the fourth opening of the fourth hinge element 29, and the first end ED5' of the third printed circuit board 2546B passes through the third opening of the hinge element 28. This facilitates the mounting of the third printed circuit boards 2546A and 2546B and also prevents the third printed circuit boards 2546A and 2546B from becoming too long, which could weaken the signal.

[0139] Please return Figure 7 The display device 20 in the second embodiment further includes a third rotating shaft 24 connecting the first display module 13 and the second display module 23. The third rotating shaft 24 includes a rotating shaft body 242, one end of the rotating shaft body 242 connected to a fifth fixing element 244, and the other end of the rotating shaft body 242 connected to a sixth fixing element 246. Based on the third rotating shaft 24, the inner side of the first display module 13 refers to the side facing the sixth fixing element 246 of the third rotating shaft 24, while the inner side of the second display module 23 refers to the side facing the fifth fixing element 244 of the third rotating shaft 24. Furthermore, the fifth fixing element 244 is disposed on the inner side of the first display area 132 of the first display module 13, and the sixth fixing element 246 is disposed on the inner side of the second display area 232 of the second display module 23. Through the arrangement of the third rotating shaft 24, the heat generated by the first display module 13 and the second display module 23 can be exchanged with the ambient air through the third rotating shaft 24 to achieve heat dissipation.

[0140] In addition, please see Figure 9 , Figure 9 This is a perspective view of a display device according to a third embodiment of the present disclosure. The difference between the third embodiment and the second embodiment lies in the position of the light source driver board 252. In the third embodiment, the light source driver board 252 of the display device 30 is disposed on the second bearing surface 2126 of the second heat sink 212. Therefore, by distributing the system board 251 and the light source driver board 252 on different heat sinks, heat can be dispersed for better heat dissipation, achieving faster heat exchange with ambient air.

[0141] Further, please refer to Figure 7 , Figure 10 and Figures 11A to 11B In some embodiments, the first display module 13 and the second display module 23 have an included angle θ, which is between 20 degrees and 180 degrees. Utilizing the rotational characteristics of the first rotating shaft 12, the second rotating shaft 22, and the third rotating shaft 24, the display devices 20, 30, and the later-described display devices 40, 50 can achieve different display angles. It is understood that... Figure 2The display device 10 can also utilize the rotational characteristics of the first rotating shaft 12 to achieve different display angles.

[0142] For a detailed explanation of the characteristics of the included angle θ (and included angle θ'), please refer to [link to relevant documentation]. Figure 7 , Figure 10 and Figures 11A to 11B , Figure 10 This is a structural side view of a display device according to the fourth embodiment of the present disclosure, and Figures 11A to 11B This is a structural side view of a display device according to the fifth embodiment of this disclosure.

[0143] like Figure 7 As shown, the first display module 13 and the second display module 23, which are connected by the third rotating shaft 24, have an included angle θ of 60 degrees.

[0144] like Figure 10 As shown, in the display device 40 of the fourth embodiment, when the included angle θ' between the first display module 13 and the second display module 23 connected by the third pivot 24 is between 10 degrees and 30 degrees, the system board 251, the light source driving board 252, and the signal component 254 are overlapped. Preferably, the included angle θ' is 20 degrees. In this embodiment, the first side of the fixing structure 11 is the first heat dissipation side 1122 of the first heat sink 112, and the second side of the fixing structure 11 is the second heat dissipation side 1124 of the first heat sink 112. In addition, in this embodiment, the second heat sink and connecting elements (such as...) of the fixing structure 11 of the fourth embodiment... Figure 6 The second heat sink 212 and connecting element 214 shown can be omitted. In this way, in addition to enabling the display device 40 to have different display angles, one of the heat sinks and / or connecting elements can be omitted, thereby reducing production costs.

[0145] In the fifth embodiment, the included angle θ is 180 degrees, depending on the different requirements of the displayed image. For example... Figure 11A As shown on the front of the display device 50, the first display module 13 and the second display module 23 are coplanar. Furthermore, as... Figure 11B As shown on the back of the display device 50, the display device 50 is fixed to the display device mounting point by the fixing structure 11 of the first heat sink 112 and the second heat sink 212. Figure 11A (Not shown). The first heat sink 112 and the heat dissipation element 145 (e.g., [missing information]) are connected via the first pivot 12. Figure 3A The first display module 13 is connected to the second heat sink 212 and the second display module 23 containing heat dissipation elements via the second pivot 22, so as to achieve heat exchange with the ambient air to achieve heat dissipation. Furthermore, compared with the heat dissipation area of ​​the second to fourth embodiments, the flat display device 50 of the fifth embodiment has a larger heat dissipation area, and can achieve heat dissipation more quickly.

[0146] In summary, the hinge positioned between the display module and the heat sink effectively dissipates heat generated by the display module through heat exchange with the environment. Furthermore, the two fixing components of the hinge are directly connected to the heat dissipation elements and the heat sink of the display module, respectively, enabling faster heat dissipation. In addition, the inclusion of an adapter board and a printed circuit board eliminates the need for a separate system board and a separate light source driver board, allowing double-sided display devices to play images and thus reducing production costs.

[0147] Although this disclosure has been presented above with reference to embodiments, it is not intended to limit this disclosure. Any person skilled in the art may make various modifications and refinements without departing from the spirit and scope of this disclosure. Therefore, the scope of protection of this disclosure shall be determined by the appended claims.
