Description

Technical Field

[0001] This invention relates to a touch display module, and more particularly to an adaptive electromagnetic shielded touch display module, belonging to the field of display module technology. Background Technology

[0002] Traditional electromagnetic shielding typically uses a fixed metal layer or conductive material, and its shielding effectiveness is determined during the design phase. It is difficult to cope with complex and ever-changing electromagnetic interference environments. Although using an electromagnetic shielding layer to fully cover the back of the display module has a good shielding effect, it affects the heat dissipation effect of the display module during use. If an edge-covering method is used, the electromagnetic shielding effect is poor.

[0003] To address these issues, an adaptive electromagnetic shielding touch display module was designed. Summary of the Invention

[0004] The main objective of this invention is to provide an adaptive electromagnetic shielding touch display module. This module forms an outer shielding layer by covering the outer edges of the touch component and the liquid crystal display component with copper foil. A first metal mesh and a second metal mesh are then positioned in the middle of this outer shielding layer. A rotating mechanism controls the rotation of the first metal mesh. This allows for dynamic adjustment of the shielding layer combination while ensuring effective heat dissipation, changing the mesh angle and altering the attenuation capability for electromagnetic waves of different frequencies. This improves anti-interference performance and enhances practicality. The rotating mechanism, composed of a heat-conducting plate on the pressure plate, a lower groove, an upper groove on the fixing ring, a heat-conducting block, a spiral bimetallic strip, a rectangular insert, a sleeve, gears, and a gear ring, can adjust the induced current generated when using copper foil as the electromagnetic shielding material, based on the intensity of electromagnetic interference in the operating environment. The temperature change caused by Joule heating is used to automatically control the rotation of the rotating mechanism, providing rotational power for the first metal mesh. It features adaptive electromagnetic shielding, requires no manual adjustment, and is more intelligent to use. By setting a sealing frame plate between the sides of the touch component and the liquid crystal display component, and setting a rectangular spiral microchannel inside the sealing frame plate, combined with a liquid metal injection mechanism consisting of a first sleeve, a first piston, liquid metal, an inner spiral tube, and a screw, and a collection and return mechanism consisting of a second sleeve, a second piston, a horizontal plate, and a return spring, it can automatically inject liquid metal into the interior of the rectangular spiral microchannel when electromagnetic interference is strong. As the intensity of electromagnetic interference increases, the amount of liquid metal injected increases.

[0035] To enable those skilled in the art to more clearly understand the technical solution of the present invention, the present invention will be further described in detail below with reference to embodiments and accompanying drawings, but the embodiments of the present invention are not limited thereto.

[0036] like Figures 1-8 As shown, this embodiment provides an adaptive electromagnetic shielded touch display module, including a touch component 1 and a liquid crystal display component 101. A copper foil 2 is provided between the top of the side of the liquid crystal display component 101 and the top of the touch component 1. A pressure plate 3 is covered on the top of the copper foil 2 and is fixed between the top of the touch component 1 and the top of the liquid crystal display component 101. An annular groove 4 is provided at the middle position of the top of the pressure plate 3. A fixing ring 5 is fixed at the top of the pressure plate 3. The annular groove 4 is located inside the fixing ring 5. A first metal mesh 6 is rotatably installed on the top of the fixing ring 5. An outer protective cover 7 is fixed on the top of the pressure plate 3 and sleeved outside the fixing ring 5. A second metal mesh 8 that fits with the first metal mesh 6 is fixed on the top of the outer protective cover 7. A rotating mechanism 9 for controlling the horizontal rotation of the first metal mesh 6 is provided between the top of the pressure plate 3 and the fixing ring 5.

[0037] A sealing frame plate 10 is provided between the side of the liquid crystal display component 101 and the top of the touch component 1. The sealing frame plate 10 is made of epoxy resin, and the inner surface is coated with a silicone rubber sealing layer. It is bonded to the touch component 1 and the liquid crystal display component 101 by a hot pressing process (temperature 150℃, pressure 5MPa). The leakage rate is ≤1×10 -9 Pa·m 3 / s, a rectangular spiral microchannel 11 is provided inside the sealing frame plate 10, a liquid metal injection mechanism 12 that communicates with the inner end of the rectangular spiral microchannel 11 is provided on the top of the liquid crystal display component 101, and a collection and return mechanism 13 that communicates with the outer end of the rectangular spiral microchannel 11 is provided on the top of the pressure plate 3. The rectangular spiral microchannel 11 and the pipes at the ends are filled with insulating oil.

[0038] Overall working principle: During use, copper foil 2 forms a fixed shielding layer on the outer side of the seam between the touch component 1 and the liquid crystal display component 101, reflecting high-frequency electromagnetic waves and effectively attenuating externally incident electromagnetic waves. The first metal mesh 6 and the second metal mesh 8 form a shielding layer at the middle position on the back of the module, ensuring the overall anti-interference effect without affecting the module's heat dissipation and touch signal. When the electromagnetic interference intensity increases, the rotating mechanism 9 drives the first metal mesh 6 to rotate, misaligning the first metal mesh 6 and the second metal mesh 8, dynamically adjusting the shielding layer combination, changing the attenuation capability for electromagnetic waves of different frequencies, thereby improving the anti-interference effect. In addition, when the electromagnetic interference intensity increases, the liquid metal injection mechanism 1... 2. Liquid metal 1203 is injected into the rectangular spiral microchannel 11, while the insulating oil inside the rectangular spiral microchannel 11 and the pipe is squeezed into the collection and return mechanism 13. The injection amount of liquid metal 1203 is self-adjusted according to the intensity of electromagnetic interference. If the increase in electromagnetic interference intensity is small, a single layer of shielding is added at the seam between the touch component 1 and the liquid crystal display component 101. If the increase in electromagnetic interference intensity is large, multiple layers of shielding are added at the seam between the touch component 1 and the liquid crystal display component 101 to improve the anti-interference effect. After the interference disappears, the liquid metal 1203 flows back to reduce the impact on the touch signal. The liquid metal 1203 is a gallium indium tin alloy (melting point 15℃, conductivity 3.4×10). 6 S / m).

[0039] In this embodiment, the rotating mechanism 9 includes a heat-conducting plate 901, a lower groove 902, an upper groove 903, a heat-conducting block 904, a spiral bimetallic strip 905, a rectangular insert 906, a sleeve 907, a gear 908, and a gear ring 909. The heat-conducting plate 901 is located inside the pressure plate 3 and covers the top of the copper foil 2. The top of the pressure plate 3 has lower grooves 902 evenly arranged in a ring array. The bottom of the fixing ring 5 has upper grooves 903 at positions corresponding to the lower grooves 902. The bottom of the lower grooves 902... A heat-conducting block 904 is provided between the end and the heat-conducting plate 901. A spiral bimetallic strip 905 is fixed to the top of each heat-conducting block 904. A rectangular insert 906 is vertically fixed to the top of each spiral bimetallic strip 905. A sleeve 907 is vertically slidably provided to the top of each rectangular insert 906. The top of the sleeve 907 extends to the top of the fixing ring 5 and is rotatably connected to the fixing ring 5 through a bearing. A gear 908 is fixed to the top of each sleeve 907. A toothed ring 909 that meshes with the gear 908 is fixed to the outside of the first metal mesh 6.

[0040] Local working principle: When copper foil 2 is used as an electromagnetic shielding material, unreflected electromagnetic waves entering copper foil 2 will induce an alternating current inside copper foil 2. Due to the resistance of copper foil 2, the current flow generates Joule heating, converting electromagnetic energy into heat energy. Under conditions of low electromagnetic interference, the heat energy is small and will not cause deformation of the spiral bimetallic strip 905. The spiral bimetallic strip 905 is made of copper (coefficient of thermal expansion 17×10⁻⁶). -6 / ℃) and steel (expansion coefficient 11×10 -6 The bimetallic strip 905 is made of a double-layer composite structure with a thickness of 0.1 mm per layer. The inner diameter of the spiral is 5 mm, the outer diameter is 15 mm, the pitch is 2 mm, and there are 5 turns in total. The initial spiral height is 10 mm at room temperature. When the electromagnetic interference is large, the heat generated is large, and the spiral bimetallic strip 905 will rotate and elongate (similar to the deformation process of the bimetallic spiral in a bimetallic thermometer). The rotation of the spiral bimetallic strip 905 will drive the rotation of the gear 908, which in turn controls the rotation of the first metal mesh 6 for adaptive adjustment. When the copper foil 2 generates Joule heat due to electromagnetic interference, the bending angle of the spiral bimetallic strip 905 increases by 15° for every 10° increase in temperature. This causes the sleeve 907 to rise by 0.5 mm through the rectangular tube 906. The gear 908 and the gear ring 909 mesh with a transmission ratio of 1:3, so that the first metal mesh 6 rotates by 5° for every 10°.

[0041] In this embodiment, the bottom end of the toothed ring 909 is fitted with the top end of the fixed ring 5, and the top end of the fixed ring 5 is uniformly mounted with balls in the circumferential direction, and the top end of the balls is in contact with the bottom end of the toothed ring 909.

[0042] Local working principle: The use of ball bearings can reduce the resistance of the toothed ring 909 during rotation, so as to quickly adjust the position of the first metal mesh 6.

[0043] In this embodiment, there are twelve sets of gears 908, and the included angle between adjacent gears 908 is the same.

[0044] Local working principle: By setting up multiple sets of gears 908, a large rotational force can be provided to the gear ring 909, ensuring the rotational adjustment of the gear ring 909 and the first metal mesh 6.

[0045] In this embodiment, the holes on the first metal mesh 6 and the second metal mesh 8 are all regular polygons and the holes are the same size. The mesh is made of electrolytic copper (purity ≥99.9%) with a wire diameter of 0.1 mm. The surface is electroplated with nickel (thickness 2 μm) to prevent oxidation. The holes are regular hexagonal with a side length of 1 mm and a hole spacing (line center distance) of 1.1 mm. The mesh is processed by etching process with an accuracy of ±0.02 mm.

[0046] Local working principle: The contact resistance between meshes of the same material is consistent, making grounding easier to handle and avoiding electromagnetic leakage or poor contact problems caused by different specifications.

[0047] In this embodiment, the width of the rectangular spiral microchannel 11 gradually increases from the inside to the outside, and the side of the rectangular spiral microchannel 11 is parallel to the middle section of the copper foil 2.

[0048] Local working principle: When electromagnetic interference increases, the number of shielding layers and the shielding area of ​​the liquid metal 1203 inside the rectangular spiral microchannel 11 will increase, and can be continuously adjusted.

[0049] In this embodiment, the liquid metal injection mechanism 12 includes a first sleeve 1201, a first piston 1202, liquid metal 1203, and a telescopic component. The first sleeve 1201 is installed at the middle position of the top of the liquid crystal display component 101. The first piston 1202 is vertically slidably disposed inside the first sleeve 1201. Liquid metal 1203 is filled between the bottom end of the first piston 1202 and the inside of the first sleeve 1201. The bottom end of the first sleeve 1201 is connected to the inner end of the rectangular spiral microchannel 11 through a pipe. The top of the first piston 1202 is provided with a telescopic component.

[0050] Local working principle: During the installation and use of the module, the back of the liquid crystal display component 101 faces downwards, and the liquid metal 1203 inside the first sleeve 1201 will not enter the interior of the rectangular spiral microchannel 11 due to gravity. When the electromagnetic interference intensity increases, the telescopic mechanism controls the interaction of the first piston 1202. At this time, the liquid metal 1203 enters the interior of the rectangular spiral microchannel 11 through the pipe and surrounds the gap on the outside of the module. As the electromagnetic interference intensity increases, the number of circles also gradually increases, and the insulating oil is squeezed into the interior of the collection and return mechanism 13.

[0051] In this embodiment, the telescopic assembly includes an inner threaded tube 1204 and a screw 1205. The top end of the first piston 1202 is fixed with the inner threaded tube 1204, and the screw 1205 is installed on the internal thread of the inner threaded tube 1204. The top end of the screw 1205 is fixedly connected to the middle position of the bottom end of the first metal mesh 6, and a vertical limiting member is provided on the outer side of the inner threaded tube 1204.

[0052] Local working principle: When the first metal mesh 6 rotates, it drives the screw 1205 to rotate. The rotation of the screw 1205 controls the movement of the inner spiral tube 1204, which in turn squeezes the first piston 1202, squeezing the liquid metal 1203 into the interior of the rectangular spiral microchannel 11. When the spiral bimetallic strip 905 controls the first metal mesh 6 to reset, the liquid metal 1203 inside the rectangular spiral microchannel 11 returns to its original position.

[0053] In this embodiment, the vertical limiting member includes a limiting rod and a vertical groove. The limiting rod is vertically fixed on the inner wall of the first sleeve 1201, and a vertical groove is vertically opened on the outer side of the inner threaded tube 1204. The end of the limiting rod extends into the interior of the vertical groove.

[0054] Local working principle: Due to the use of the limiting rod, the internal threaded tube 1204 is limited to ensure that the internal threaded tube 1204 can only move vertically up and down.

[0055] In this embodiment, the reflux collection mechanism 13 includes a second sleeve 1301, a second piston 1302, a horizontal plate 1303, and a return spring 1304. The second sleeves 1301 are evenly fixed at the four corners of the pressure plate 3. The second sleeves 1301 are interconnected. The bottom end of the second sleeve 1301 is connected to the outer end of the rectangular spiral microchannel 11 through a pipe. The inner bottom of each second sleeve 1301 is vertically slidably provided with a second piston 1302. The top end of the second sleeve 1301 is fixed with a horizontal plate 1303. A return spring 1304 is provided between the bottom of the horizontal plate 1303 and the second piston 1302.

[0056] Local working principle: After the insulating oil enters the interior of the second sleeve 1301, it will squeeze the second piston 1302 and compress the return spring 1304. When the interference disappears, the liquid metal 1203 flows back into the insulating oil and is squeezed into the interior of the rectangular spiral microchannel 11 again under the pressure of the return spring 1304.

[0057] The above description is merely a further embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope disclosed in the present invention, based on the technical solution and concept of the present invention, shall fall within the scope of protection of the present invention.
