[0019] In order to provide a further understanding of the purpose, structure, features and functions of the present invention, the following detailed description is given in conjunction with the embodiments.

[0020] Please refer to Figure 1 、 Figure 2 ,and Figure 3 As shown, Figure 1 is a schematic internal diagram of a display device according to an embodiment of the present invention, Figure 2 FIG. 1 is a schematic diagram of the interior of a display device from another perspective according to an embodiment of the present invention. Figure 3The figure is a schematic diagram of a display device according to an embodiment of the present invention. The embodiment of the present invention provides a display device 100, which includes a panel 11, a frame 12, a light source 13, and a water-cooling strip 14; the frame 12 is arranged on the back of the panel 11, and the rectangular frame 12 has four sides, wherein the side adjacent to the light source 13 is a first side 121, and the first side 121 and the panel 11 are not attached but separated to form an accommodating space 111, and the accommodating space 111 isolates the light source 13 and the panel 11 in a first direction A1, and the first direction A1 is the normal direction of the panel 11; the water-cooling strip 14 is arranged between the panel 11 and the frame 12, and the water-cooling strip 14 is in the shape of a strip extending along a second direction A2, and the second direction A2 is the direction in which the first side 121 extends, and the water-cooling strip 14 has a first surface 1411, a second surface 1412, an internal space 141, an inlet 142, and an outlet 143, and the first surface 1411 is parallel to the panel 11 and faces The panel 11, the second surface 1412 is parallel to the panel 11 and faces the first side 121 of the frame 12. At least a portion of the first surface 1411 and the second surface 1412 of the water-cooling strip 14 are located in the accommodating space 111. There is liquid in the internal space 141. The inlet 142 of the water-cooling strip 14 is located at one end of the water-cooling strip 14, and the outlet 143 is located at the other end of the water-cooling strip 14. The temperature of the water-cooling strip 14 can be controlled by the liquid flowing through the inlet 142, the internal space 141 and the outlet 143. When the light source 13 generates heat, part of the heat will be transferred to the panel 11 in the traditional design, causing a strip-shaped high-temperature hot spot to be generated in the area corresponding to the light source 13 on the surface of the panel 11. However, due to the presence of the water-cooling strip 14, regardless of the heat changes of the light source 13, the water-cooling strip 14 can maintain its own temperature stable through heat exchange with the fluid, thereby controlling the temperature rise in the area corresponding to the light source 13 on the surface of the panel 11 within the specification.

[0021] Reference Figure 1 、 Figure 2 ,and Figure 3 As shown, the light source 13 of the display device 100 is a side-lit device. Light source 13 is disposed on a first side 121 of the frame 12 and arranged in a strip shape along at least one side of a rectangular panel 11. Light emitted by light source 13 passes through a light guide plate 15, then changes direction and exits from panel 11, which is a glass panel of the display device 100. Panel 11 has a front and a back, with the front facing outward and the back facing the enclosed space 112 of the display device 100. In a specific embodiment, light source 13 is an LED (light-emitting diode) light bar. Light source 13 is strip-shaped along a second direction A2, which is perpendicular to first direction A1. Panel 11 is a glass plate or a transparent plastic plate. Light is emitted through panel 11, depending on the actual situation and is not limited thereto.

[0022] Reference Figure 1 、 Figure 2 ,and Figure 3 As shown, the shape of the water-cooling strip 14 in the cross section perpendicular to the second direction A2 is stepped, and the cross section of the water-cooling strip 14 has a thick end 1401 and a thin end 1402, the thick end 1401 has a first thickness D1, and the thin end 1402 has a second thickness D2, the first thickness D1 is greater than the second thickness D2, at least a portion of the thin end 1402 is located in the accommodating space 111, the thick end 1401 is located outside the accommodating space 111 and the thick end 1401 is located on the outside of the frame 12. Specifically, the water-cooling strip 14 presents a step-like shape in a cross-section perpendicular to the second direction A2, which is determined by the shape of the frame 12 on the first side 121. The water-cooling strip 14 matches the accommodating space 111 formed by the frame 12 and the panel 11, thereby solving the problem of heat generated by the light source 13 in the thin display device 100 being directly transferred to the surface of the panel 11, forming a strip-shaped concentrated high-temperature area. Due to the reduced overall thickness of the thin display device 100, the accommodating space 111 between the frame 12 and the panel 11 is usually very narrow. That is, the gap between the frame 12 and the panel 11 is usually very narrow. As a result, whether filling the accommodating space 111 with insulation material, using heat diffusion materials such as copper foil, aluminum foil or graphite sheets, or using a fan to force convection into the accommodating space 111 to prevent the formation of a strip-shaped concentrated high-temperature area on the surface of the panel 11, the effect is limited.

[0023] Reference Figure 1 、 Figure 2 ,and Figure 3 As shown, the water-cooling strip 14 has a first surface 1411, a second surface 1412 and a third surface 1413. The first surface 1411 is parallel to the panel 11 and faces the panel 11, and the second surface 1412 is parallel to the panel 11 and faces the frame 12. An inlet 142 and an outlet 143 are respectively provided at both ends of the third surface 1413. Liquid flows into the inlet 142, and the liquid flows through the internal space 141 and then flows out from the outlet 143. The liquid can be water. The heat generated by the light source 13 is conducted to the nearby components for heat dissipation. In a traditional design, one of the main heat conduction paths is through the frame 12, the accommodating space 111 and the panel 11 and then dissipated into the air. This path causes a strip-shaped high-temperature area to be generated on the panel 11 at the position corresponding to the light source 13. However, due to the addition of the water-cooling strip 14, this conduction path passes through the frame 12 and enters the water-cooling strip 14. The cold water takes away the heat after passing through the water-cooling strip 14, thereby improving the local strip-shaped high-temperature phenomenon of the panel 11. In specific implementation, the first surface 1411 of the water-cooling strip 14 can be attached to the panel 11 to enhance heat dissipation, or a gap can be left between the first surface 1411 of the water-cooling strip 14 and the panel 11 to reduce the local surface temperature of the panel 11, depending on actual conditions and is not limited to this.

[0024] Reference Figure 1 、 Figure 2 ,and Figure 3As shown, the water-cooling strip 14 is made of extruded aluminum, which can easily be hollowed with a wall thickness as thin as 0.5 mm and up to several meters in length. This thin-walled aluminum extrusion is positioned within the accommodating space 111 between the frame 12 and the panel 11. The flow of coolant within the water-cooling strip 14 maintains a roughly uniform temperature across its first and second surfaces 1411, 1412. This improves the previously concentrated high-temperature area on the panel 11 corresponding to the light source 13, allowing it to spread across the entire width of the first surface 1411, at least in the A3 direction. This third direction A3 is perpendicular to both the first and second directions A1 and A2. Furthermore, the heat absorbed by the water-cooling strip 14 is further carried by the coolant to an external water tank for cooling.

[0025] Reference Figure 1 、 Figure 2 ,and Figure 3 As shown, the frame 12 has a backlight module front frame and a backlight module back cover 191, wherein the backlight module front frame includes a first portion 122 and a second portion 123. There is a gap between the first portion 122 and the panel 11, also known as an accommodating space 111. The back cover 191 and the second portion 123 are buckled together. The light source 13 is set on the back cover 191, and at least a portion of the water cooling strip 14 is set between the panel 11 and the first portion 122. In practice, the plane where the first portion 122 is located is nearly parallel to the plane where the panel 11 is located, and the first portion 122 and the second portion 123 are nearly perpendicular. Figure 1 、 Figure 2 ,and Figure 3 As shown, the first surface 1411 of the water-cooling strip 14 is adjacent to the panel 11, the second surface 1412 of the water-cooling strip 14 is adjacent to the first portion 122 of the front frame 12, and the inlet 142 and outlet 143 of the water-cooling strip 14 are respectively disposed on the third surface 1413 of the water-cooling strip 14. Cold water flows through the inlet 142, the internal space 141, and the outlet 143, so that the heat flow path of the light source 13 is blocked by the water-cooling strip 14, and the heat is first diffused over a larger area before being transferred to the surface of the panel 11.

[0026] Reference Figure 1 、 Figure 2 ,and Figure 3As shown, the water-cooling bar 14 includes a first cooling bar 144 and a second cooling bar 145. The first cooling bar 144 is arranged between the panel 11 and the frame 12, and at least a portion of the first cooling bar 144 is located in the accommodating space 111. The second cooling bar 145 is arranged between the panel 11 and the frame 12, and at least a portion of the second cooling bar 145 is located in the accommodating space 111. The first cooling bar 144 and the second cooling bar 145 are located in a vertical column along the first direction A1 on the first side 121 of the frame 12. In a specific implementation, when the display device 100 is a large-size display, the length of the first side 121 of the frame 12 is longer, and the coolant flows in from the inlet 143. The water-cooling strip 14 can maintain its own temperature through heat exchange of the fluid. The coolant flows through the internal space of the first water-cooling strip 144 and the second water-cooling strip 145 respectively and takes away the heat in the accommodating space 111 between the panel 11 and the frame 12, thereby controlling the temperature rise of the area corresponding to the light source 13 on the surface of the panel 11 within the specification. However, due to the long length of the internal space 141, the cold water becomes hot in the middle of the flow and cannot continue to dissipate heat, resulting in insufficient heat dissipation effect. The water-cooling strip 14 can be arranged in sections, and double-circulation cooling and heat dissipation can be achieved by using the first cooling strip 144 and the second cooling strip 145 arranged vertically in the length direction, which is better for cooling the panel 11 and improving the local strip high temperature phenomenon.

[0027] Reference Figure 1 、 Figure 2 ,and Figure 3As shown, the first cooling strip 144 has a first space, a first inlet 1442 and a first outlet 1443, the second cooling strip 145 has a second space, a second inlet 1452 and a second outlet 1453, the first side 121 of the frame 12 has a first end 1211 and a second end 1212, the first end 1211 and the second end 1212 are opposite, the first inlet 1442 of the first cooling strip 144 is located between the first end 1211 and the second end 1212 of the first side 121, the first outlet 1443 of the first cooling strip 144 is located at the first end 1211 of the first side 121, and the second inlet 1452 of the second cooling strip 145 is located at the first end 1211 of the first side 121 1 and the second end 1212, the second outlet 1453 of the second cooling strip 145 is located at the second end 1212 of the first side 121. Liquid flows through the first inlet 1442, the first space 1441, and the first outlet 1443 of the first cooling strip 144 to reduce the temperature of the panel 11. Liquid flows through the second inlet 1452, the second space 1451, and the second outlet 1453 of the second cooling strip 145 to reduce the temperature of the panel 11. The heat generated by the light source 13 is diffused to a larger area by the first water-cooling strip 144 and the second cooling strip 145, and its heat flow path is blocked by the first water-cooling strip 144 and the second cooling strip 145, so that less heat is transferred to the surface of the panel 11. During specific implementation, the light source 13 located on the first side 121 of the frame 12 emits light and generates heat, the first cooling bar 144 is arranged on the left half of the first side 121, and the second cooling bar 144 is arranged on the right half of the first side. Cold water flows from the middle of the first side 121 through the first cooling bar 144 on the left half and the second cooling bar 145 on the right half at the same time. After the cold water absorbs heat, it flows out from the first end 1211 and the second end 1212 of the first side 121 at the same time.

[0028] Reference Figure 1 、 Figure 2 ,and Figure 3 As shown, the radiator 16 is located inside the display device 100. Cold water flows out of the radiator 16, passes through the water-cooling strips 14, and absorbs heat to become hot water. The hot water flows back from the water-cooling strips 14 to the radiator 16, and the radiator 16 cools the hot water to become cold water. This process is repeated to reduce the temperature of the panel 11 and improve the local high temperature phenomenon.

[0029] Reference Figure 1 、 Figure 2 ,and Figure 3As shown, the display device 100 has a liquid inlet pipe 17 and a liquid outlet pipe 18. Liquid flows into the liquid inlet pipe 17, passes through the inlet 142, the internal space 141, and the outlet 143, and then reaches the liquid outlet pipe 18 to absorb the heat transferred from the light source 13 to the cooling strip 14. Specifically, one end of the liquid inlet pipe 17 is disposed at the inlet 142 of the water-cooling strip 14, and the other end of the liquid inlet pipe 17 is disposed at the radiator 16. One end of the liquid outlet pipe 18 is disposed at the outlet 143 of the water-cooling strip 14, and the other end of the liquid outlet pipe 18 is disposed at the radiator 16. The liquid flows out of the radiator 16 through the water-cooling strip 14, passes through the liquid inlet pipe 17, the inlet 142, the internal space 141, the outlet 143, and the liquid outlet pipe 18, and then flows back to the radiator 16. When the liquid flows through the water-cooling strip 14, it takes away the heat from the light source 13, thereby achieving the effect of reducing the surface temperature of the panel 11.

[0030] Reference Figure 1 、 Figure 2 ,and Figure 3 As shown, the liquid inlet pipe 17 has a first cold pipe 171 and a second cold pipe 181, and the liquid outlet pipe 18 has a first heat pipe 172 and a second heat pipe 182. One end of the first cold pipe 171 is arranged on the radiator 16, and the other end of the first cold pipe 171 is arranged on the first inlet 1442 of the first cooling bar 144. One end of the first heat pipe 172 is arranged on the radiator 16, and the other end of the first heat pipe 172 is arranged on the first outlet 1443 of the first cooling bar 144. One end of the second cold pipe 181 is arranged on the radiator 16, and the other end of the second cold pipe 181 is arranged on the second inlet 1452 of the second cooling bar 145. One end of the second heat pipe 182 is arranged on the radiator 1 6. The other end of the second heat pipe 182 is disposed at the second outlet 1453 of the second cooling bar 145. The first cooling pipe 171, the second cooling pipe 181, the first heat pipe 172, and the second heat pipe 182 all extend from the radiator 16 parallel to the panel 11. After flowing out of the radiator 16, the liquid flows through the first cooling pipe 171, the first inlet 1442 of the first cooling bar 144, the first space 1441, the first outlet 1443, the first heat pipe 172, and then flows back to the radiator 16. The liquid also flows through the second cooling pipe 181, the second inlet 1452 of the second cooling bar 145, the second space 1451, the second outlet 1453, the second heat pipe 182, and then flows back to the radiator 16.

[0031] Reference Figure 1 、 Figure 2 ,and Figure 3As shown, the display device 100 further includes a rear housing 192, which is combined with the panel 11 to form a closed space 112. The closed space 112 accommodates the backlight module frame 12, light source 13, water cooling strips 14, light guide layer 15, radiator 16, liquid inlet pipe 17, and liquid outlet pipe 18. Because the components within the closed space 112 are compact, directly using a fan to generate convection for heat dissipation would be ineffective. Therefore, the water cooling strips 14 are disposed between the panel 11 and the frame 12 to reduce the maximum surface temperature of the panel 11 within the limited structural space.

In this way, the water-cooling strip can maintain its own temperature through heat exchange of the fluid, and then the temperature rise of the area corresponding to the light source on the panel surface is controlled within the specification.
