[0020] The first glass plate 10 , the second glass plate 11 , the ITO sheet 20 , the heating FPC 30 , the semiconductor thermoelectric power generation sheet 40 , and the power generation FPC 50 . DETAILED DESCRIPTION
[0021] In order to facilitate the understanding of the present invention, the present invention will be described more comprehensively below with reference to the relevant drawings.
[0022] The present application proposes a low-energy glass heating assembly, comprising: a first glass plate 10, a second glass plate 11, an ITO sheet 20, a heating FPC 30, an optical adhesive layer, a semiconductor temperature difference power generation sheet 40, a power generation FPC 50 and a battery. The battery is a rechargeable battery. The heating FPC 30 controls the ITO sheet 20 to generate heat, and the ITO sheet 20 is attached to the upper surface of the semiconductor temperature difference power generation sheet 40. When the ITO sheet 20 generates heat, the temperature of the upper surface of the semiconductor temperature difference power generation sheet 40 is higher than the temperature of its lower surface, and the semiconductor temperature difference power generation sheet 40 converts the temperature difference between the upper and lower surfaces into electrical energy, and stores the generated electrical energy in the battery, and then the battery provides electrical energy for the heat generation of the ITO sheet 20, realizing energy recovery, thereby reducing the energy consumption of the touch screen.
[0023] Specifically, see Figure 1 , the first glass plate 10 and the second glass plate 11 are bonded and fixed by an optical adhesive layer. An ITO sheet 20 is provided on the side of the second glass plate 11 away from the first glass plate 10. The ITO sheet 20 is made of transparent glass and a heating sheet is provided inside it. The heating FPC 30 is electrically connected to the ITO sheet 20, and a circuit for controlling the ITO sheet 20 to start the heating function is provided in the heating FPC 30. The side of the ITO sheet 20 away from the second glass plate 11 is connected to the semiconductor thermoelectric power generation sheet 40, and the power generation FPC is electrically connected to the semiconductor thermoelectric power generation sheet 40. The semiconductor thermoelectric power generation sheet 40 converts its own temperature difference into electrical energy, and the converted electrical energy is used to charge the battery. Among them, the first glass plate 10 and the second glass plate 11 are AMoled glasses. In addition, the first glass plate 10 and the second glass plate 11 are arranged in parallel, so that the contrast and clarity of the touch surface on the entire touch screen are consistent.
[0024] It should be noted that when the low-energy glass heating assembly is powered on, the ITO sheet 20 starts the heating function to prevent the water vapor in the air from liquefying into water droplets on the first glass plate 10, which affects the touch sensitivity of the product. When the ITO sheet 20 continues to generate heat, the temperature of the upper surface of the semiconductor thermoelectric power generation sheet 40 is higher than the temperature of its lower surface, and the semiconductor thermoelectric power generation sheet 40 converts the temperature difference between the upper and lower surfaces into electrical energy, and stores the generated electrical energy in the battery, and then the battery provides electrical energy for the heat generation of the ITO sheet 20, realizing energy recovery, thereby reducing the energy consumption of the touch screen.
[0025] In one embodiment, see Figure 1The length of the ITO sheet 20 is respectively greater than the length of the first glass plate 10 and the length of the second glass plate 11, and the width of the ITO sheet 20 is respectively greater than the width of the first glass plate 10 and the width of the second glass plate 11, so that the temperature on the first glass plate 10 and the second glass plate 11 is consistent, avoiding a temperature difference between the two sides of the first glass plate 10 and the second glass plate 11, causing the user's fingers to feel an obvious temperature difference on the touch surface, affecting the user's touch experience of the product.
[0026] Furthermore, a temperature sensor is provided on one side of the ITO sheet 20, and the temperature sensor is used to convert the temperature signal on the first glass plate 10 and the second glass plate 11 into an electrical signal, and then the electrical signal is converted into a specific value of the temperature through analysis and processing by the main board, so that the user can control the temperature on the first glass plate 10 and the second glass plate 11. The system in the low-energy glass heating assembly is provided with a temperature threshold. When the ITO sheet 20 heats the first glass plate 10 and the second glass plate 11 to the set maximum temperature, the system controls the ITO sheet 20 to cut off the power. When the temperature of the first glass plate 10 and the second glass plate 11 is lower than the minimum temperature, the system controls the ITO sheet 20 to start heating, thereby further reducing the energy consumption of the product and preventing the ITO sheet 20 from being overheated, causing the product to burn.
[0027] Furthermore, the length of the semiconductor thermoelectric power generation sheet 40 is the same as the length of the ITO sheet 20, and the width of the semiconductor thermoelectric power generation sheet 40 is the same as the width of the ITO sheet 20, so that the heat generated in the ITO sheet 20 can be recovered by the semiconductor thermoelectric power generation sheet 40 to the greatest extent, so as to directly convert the thermal energy on the ITO sheet 20 into electrical energy.
[0028] Please refer again Figure 1 The semiconductor thermoelectric power generation sheet 40 is aligned with the ITO sheet 20 so that there is a certain temperature difference between the upper and lower surfaces of the semiconductor thermoelectric power generation sheet 40, which can be efficiently converted into electrical energy, avoiding waste of materials of the semiconductor thermoelectric power generation sheet 40 and improving the utilization rate of the semiconductor thermoelectric power generation sheet 40.
[0029] In another embodiment, both the heating FPC30 and the power generation FPC50 are provided with welding areas, and the welding areas are used to weld electronic components such as capacitors, resistors, and triodes. The electronic components are connected in an ingenious manner to form a heating circuit or a power generation circuit that can realize a certain function. The heating FPC30 and the power generation FPC50 are both soft FPCs, so the heating FPC30 and the power generation FPC50 are provided with support sheets on the opposite sides of their welding areas. The support sheet supports the electronic components in the welding area to prevent the heating FPC30 and the power generation FPC50 from being deformed and bent due to exceeding the bearing capacity. Further, the low-energy glass heating assembly also includes a second double-sided adhesive layer and a steel sheet, and both sides of the second double-sided adhesive layer have strong adhesion. The heating FPC30 is connected to the edge of the bonding surface of the ITO sheet 20. The connection between the heating FPC30 and the ITO sheet 20 is provided with a second double-sided adhesive layer. The second double-sided adhesive layer is bonded to a steel sheet on one side away from the heating FPC 30 . The steel sheet has a strong hardness and can support the connection between the heating FPC 30 and the ITO sheet 20 to prevent the heating FPC 30 from breaking.
[0030] In addition, the optical adhesive layer is OCA adhesive, which has good light transmittance, and the light transmittance can reach more than 90%, thereby improving the display clarity of the touch screen.
[0031] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
