[0030] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only some embodiments of the present invention, not all embodiments. The following description of at least one exemplary embodiment is actually only illustrative and is in no way intended to limit the present invention and its application or use. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0031] like Figures 1 to 6 As shown, an embodiment of the present invention provides a display module, which includes a module body 10 and a thermal conversion component 20. The thermal conversion component 20 is arranged on the module body 10. The thermal conversion component 20 includes a plurality of thermal conversion modules 21 capable of converting thermal energy into electrical energy. The plurality of thermal conversion modules 21 are connected in series in sequence.

[0032] The display module provided in this embodiment uses multiple thermal-to-electrical modules 21 to convert the heat energy generated by the display screen when it is working into electrical energy. Since the multiple thermal-to-electrical modules 21 are connected in series in sequence, they can be boosted in series, making it convenient to use the converted electrical energy to power other devices, or to store the converted electrical energy, thereby realizing the recycling of the heat generated by the display screen and improving the energy utilization rate.

[0033] It should be noted that the thermoelectric module 21 is a device that can directly convert thermal energy into electrical energy. This technology is also known as thermoelectric conversion technology. It utilizes the Seebeck effect. Simply put, the Seebeck effect describes the voltage (electromotive force) generated at the junction of two different conductive or semiconductor materials when a temperature difference exists between the two ends. This effect is the basis for the thermoelectric module to convert thermal energy into electrical energy.

[0034] The following are the key steps in the operation of the heat-to-electricity module:

[0035] 1. Temperature difference generation: One end of the heat-to-electricity module (called the hot end or hot side) contacts the heat source, while the other end (called the cold end or cold side) contacts the lower temperature environment or dissipates heat through the cooling system.

[0036] 2. Electron flow: Due to the temperature difference, electrons at the hot end have higher energy than those at the cold end. At the hot end, high-energy electrons will leave, causing the area to become positively charged; while at the cold end, electrons will gather, causing the area to become negatively charged.

[0037] 3. Voltage generation: The flow of electrons between the hot and cold ends forms an electric current, which generates a voltage difference between the two junctions.

[0038] 4. Power output: This voltage can be connected to the circuit of the thermal-to-electrical module to drive an external load, thereby converting thermal energy into electrical energy.

[0039] 5. Thermoelectric Material Properties: Thermal-to-electric modules are typically made of specialized thermoelectric materials, such as bismuth telluride (Bi2Te3), lead telluride (PbTe), or silicon-germanium alloys. The thermoelectric properties of these materials (such as the Seebeck coefficient, electrical conductivity, and thermal conductivity) determine the module's overall conversion efficiency.

[0040] 6. Efficiency and Optimization: The efficiency of a heat-to-electric module is influenced by multiple factors, including the choice of thermoelectric material, module design, the temperature difference between the heat source and the cold end, and thermal management strategies. To improve efficiency, researchers and engineers continuously optimize these parameters.

[0041] This energy conversion method of the heat-to-electricity module has the advantages of no moving parts, no need for fuel, no emissions and low maintenance.

[0042] like Figure 1 、 Figures 4 to 6 As shown, in this embodiment, the module body 10 includes a back cover 11, a bottom shell 12 and a light board 13. The back cover 11 and the light board 13 are respectively located on both sides of the bottom shell 12 and connected to the bottom shell 12. Multiple thermal conversion modules 21 are all arranged on the back cover 11.

[0043] By arranging multiple thermal-to-electrical modules 21 on the rear cover 11 , the multiple thermal-to-electrical modules 21 and the rear cover 11 are integrated into a rear cover back plate, which can improve the component integration of the device and facilitate assembly.

[0044] In this embodiment, the light board 13 is located on the front side of the bottom shell 12 , and the rear cover 11 is located on the rear side of the bottom shell 12 .

[0045] The light board 13 includes a board body and LED lights mounted on the board body. The light board 13 is the main part of the LED display screen. Its function is to directly convert electrical signals into light signals and display images and text information by controlling the on and off and brightness of single or multiple LED lights.

[0046] like Figure 1 As shown, in this embodiment, multiple thermal conversion modules 21 are located on the side of the rear cover 11 facing the bottom case 12. These modules are not exposed, which improves the smoothness of the device's housing and facilitates assembly of the display module with other components. Furthermore, the rear cover 11 protects the modules 21 from damage due to collisions.

[0047] like Figure 1 and Figure 2 As shown, the bottom case 12 is provided with a plurality of first avoidance holes 121, and the plurality of thermal-to-electrical modules 21 are disposed in a one-to-one correspondence within the plurality of first avoidance holes 121. Using the first avoidance holes 121 to accommodate the thermal-to-electrical modules 21 reduces the space occupied by the thermal-to-electrical modules 21 in the thickness direction of the display module, thereby reducing the thickness of the display module and achieving a thinner and lighter display screen.

[0048] The shape of the first avoidance hole 121 matches the shape of the portion of the heat-to-electricity module 21 that passes through the first avoidance hole 121 .

[0049] The rear cover 11 and the bottom shell 12 are detachably connected, so as to facilitate the repair and replacement of components inside the display module.

[0050] In this embodiment, the rear cover 11 and the bottom shell 12 are snap-connected, which has the advantage of being easy to assemble and can improve assembly efficiency.

[0051] It should be noted that the snap-fit ​​connection between the back cover 11 and the bottom shell 12 includes the following two structures: a direct snap-fit ​​connection between the back cover 11 and the bottom shell 12, or an indirect snap-fit ​​connection between the back cover 11 and the bottom shell 12. The direct snap-fit ​​connection between the back cover 11 and the bottom shell 12 refers to a first snap-fitting member provided on the back cover 11 and a second snap-fitting member provided on the bottom shell 12, and the first snap-fitting member and the second snap-fitting member are snap-fitted together to achieve a direct snap-fit ​​connection between the back cover 11 and the bottom shell 12. The indirect snap-fit ​​connection between the back cover 11 and the bottom shell 12 refers to a snap-fitting connection between the back cover 11 and the bottom shell 12 via other components, such as a snap-fitting connection via the thermal conversion module 21, i.e., a first snap-fitting member provided on the thermal conversion module 21 and a second snap-fitting member provided on the bottom shell 12, and the first snap-fitting member and the second snap-fitting member are snap-fitted together to achieve an indirect snap-fit ​​connection between the back cover 11 and the bottom shell 12.

[0052] In this embodiment, the back cover 11 is indirectly connected to the bottom shell 12 by snap-fitting.

[0053] like Figure 1 As shown, a buckle 211 is provided on the side wall of the thermal-to-electrical module 21 , and a slot is provided on the bottom shell 12 . The buckle 211 is snap-connected with the slot to achieve an indirect snap-connection between the back cover 11 and the bottom shell 12 .

[0054] Furthermore, by providing the buckles 211 on the side walls of the thermal-to-electrical module 21 , it is unnecessary to provide any other snap-fitting structures on the back cover 11 . After the back cover 11 is placed on the bottom housing 12 , the outer surface flatness of the display module can be improved.

[0055] like Figure 1 As shown, in this embodiment, a second avoidance hole 111 is provided on the rear cover 11 , and the heat conversion modules 21 at the ends of the plurality of heat conversion modules 21 have connecting wires, which pass through the second avoidance hole 111 .

[0056] Multiple display modules can be connected in parallel via connecting wires to increase current. The second avoidance holes 111 can be used to avoid the connecting wires, making it easier to route the connecting wires.

[0057] like Figure 1 、 Figure 4 as well as Figure 6 As shown, the back cover 11 is provided with a third avoidance hole 112, and the lamp board 13 is provided with a terminal 131, which is passed through the third avoidance hole 112. The third avoidance hole 112 can avoid the terminal 131, so that the terminal 131 is easy to connect with other components.

[0058] like Figure 7As shown, another embodiment of the present invention provides a display screen, which includes a plurality of display modules 30 provided above, and utilizes a plurality of thermal-to-electrical modules 21 of the display module 30 to convert the heat energy generated when the display screen is working into electrical energy. Since the plurality of thermal-to-electrical modules 21 are connected in series in sequence, the voltage can be boosted by series connection, which makes it convenient to utilize the converted electrical energy to power other devices, or to store the converted electrical energy, thereby realizing the recycling of the heat generated by the display screen and improving the energy utilization rate.

[0059] In this embodiment, multiple display modules 30 are arranged in an array. Multiple display modules 30 in each row are connected in series to form a module row, and multiple module rows are connected in parallel. The series arrangement of multiple display modules 30 in each row further boosts voltage, while the parallel arrangement of multiple module rows increases current.

[0060] like Figure 7 As shown, in this embodiment, the display screen further includes a storage element 40 and a bus. Multiple module rows are arranged in parallel on the bus. The bus is electrically connected to the storage element 40 to store the converted electrical energy through the storage element 40.

[0061] The electrical storage device 40 has a charging port, and the bus is electrically connected to the charging port.

[0062] In this embodiment, the power storage device 40 is a battery and is located below the plurality of display modules 30 .

[0063] Display screens include outdoor displays. Outdoor displays generate a lot of heat, primarily due to the large number of LEDs they use, each of which generates heat when emitting light. This heat generation is particularly significant at high brightness and high refresh rates. In this embodiment, multiple heat-to-electricity modules 21 are used to convert the heat generated by the outdoor display screen into electrical energy, thereby conserving energy.

[0064] It should be noted that the heat-to-electricity module 21 has the following beneficial effects:

[0065] 1. No mechanical moving parts: Since there is no mechanical movement involved, the heat-to-electricity module has a long service life and high reliability, while reducing maintenance costs;

[0066] 2. Environmentally friendly: The heat-to-electricity module is noiseless and emission-free when working, and is a clean energy conversion method;

[0067] 3. Small size and high flexibility: The module can be designed into different sizes and shapes as needed, suitable for occasions with limited space;

[0068] 4. Instant energy conversion: The thermal-to-electrical module can instantly convert thermal energy into electrical energy with a fast response speed.

[0069] The device provided by the embodiment has the following beneficial effects:

[0070] (1) The heat energy generated by the display screen during operation is converted into electrical energy by using the multiple heat-to-electricity conversion modules 21 of the display module 30, thereby recycling the heat generated by the display screen and improving energy utilization;

[0071] (2) Since the multiple heat-to-electricity modules 21 of the display module 30 are sequentially connected in series, the voltage can be increased by the series connection. Since the multiple display modules 30 in each row are arranged in series, the voltage can be further increased. Since the multiple module rows are arranged in parallel, the current can be increased, making it easier to use the converted electrical energy to power other devices or store the converted electrical energy.

[0072] (3) The rear cover 11 and the bottom shell 12 are snap-connected, which facilitates assembly and improves assembly efficiency;

[0073] (4) The first avoidance hole 121 is used to avoid and accommodate the thermal conversion module 21, which can reduce the space occupied by the thermal conversion module 21 in the thickness direction of the display module, thereby reducing the thickness of the display module and achieving a thinner display screen;

[0074] (5) The second avoidance hole 111 can be used to avoid the connecting wire, which is convenient for the wiring of the connecting wire. The third avoidance hole 112 can be used to avoid the terminal 131, which is convenient for the terminal 131 to be connected to other components.
