Description

Technical Field

[0001] This utility model relates to the field of touch panel technology, specifically to a home appliance control display panel. Background Technology

[0002] A home appliance control display panel is a type of touch panel that primarily achieves input functions by detecting physical changes at touch points (such as resistance, capacitance, pressure, or optical signals).

[0003] Among existing home appliance control display panels, flexible panels have been widely used due to their unique advantages such as bendability and foldability. Flexible panels typically consist of a flexible substrate layer and an electrode layer. The flexible substrate layer generally adopts a multi-layer composite structure, which has good flexibility. However, flexible touch panels still have some structural shortcomings. The electrode layer has poor bending resistance. After repeated bending, the internal electrode circuits are prone to breakage or short circuits, affecting the stability of touch function. Utility Model Content

[0004] The purpose of this utility model is to provide a home appliance control display panel to solve the above-mentioned problems.

[0005] This utility model achieves the above-mentioned objectives through the following technical solution: a home appliance control display panel, comprising a flexible substrate layer, an electrode layer, and a protective layer. The flexible substrate layer is formed by laminating an inner layer and an outer layer. The inner layer is made of a high-molecular elastic material, and the outer layer is made of a fiber-reinforced material. The electrode layer includes multiple lateral electrodes and longitudinal electrodes. The lateral electrodes are made of silver nanowires, and the longitudinal electrodes are made of graphene composite material. The lateral and longitudinal electrodes are arranged in an interleaved embedded structure. A stress buffer layer is provided between the electrode layer and the protective layer. The stress buffer layer includes a first surface layer and a second surface layer. Both the first and second surface layers are made of silicone material. A filling space is provided between the first and second surface layers, and multiple elastic particles are disposed inside the filling space. The elastic particles are spherical.

[0006] As a further feature of this invention, each of the first and second surface layers has an embedding hole for embedding elastic particles, the diameter of which is smaller than the particle size of the elastic particles.

[0007] As a further feature of this invention, the protective layer is a parylene coating.

[0008] As a further feature of this invention, the thickness of the inner layer is 0.1mm-0.5mm, and the thickness of the outer layer is 0.2mm-0.4mm.

[0009] As a further feature of this invention, the thickness of the first and second surface layers is 0.1mm-0.3mm.

[0010] As a further feature of this invention, the particle size of the elastic particles is 0.5mm-0.8mm.

[0011] Compared with the prior art, the beneficial effects of this utility model are: This invention incorporates a stress buffer layer. When the panel is bent by external force, the elastic particles undergo elastic deformation, which disperses the pressure and provides a buffering effect through active deformation. This reduces the stress on the electrode layer, effectively protecting the electrode circuitry and preventing breakage or short circuits, thus ensuring the stability of the panel's touch function.

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0015] Please see Figure 1 , Figure 2As shown, a home appliance control display panel includes a flexible substrate layer 1, an electrode layer 2, and a protective layer 3. The protective layer 3 is a transparent parylene coating, which has good flexibility, wear resistance, and corrosion resistance. It can effectively prevent external scratches, wear, and chemical corrosion from damaging the electrode layer 2 and the flexible substrate layer 1, while not affecting the panel's light transmittance and touch sensitivity. The flexible substrate layer 1 is formed by laminating an inner layer 4 and an outer layer 5. The inner layer 4 is made of a high-molecular elastic material, such as polyurethane elastomer. The high-molecular elastic material layer has good elastic recovery ability and can quickly return to its original shape after bending, thereby reducing the tensile and compressive stress on the electrode circuit and effectively protecting the electrode circuit. The outer layer 5 is made of a fiber-reinforced material, such as glass fiber. The fiber-reinforced material layer improves the overall strength and wear resistance of the flexible substrate layer 1. This design makes it less prone to breakage during repeated bending, improving durability. The inner layer 4 has a thickness of 0.1mm-0.5mm, and the outer layer 5 has a thickness of 0.2mm-0.4mm. The electrode layer 2 includes multiple transverse and longitudinal electrodes. The transverse electrodes are made of silver nanowires, and the longitudinal electrodes are made of graphene composite material. The silver nanowires have excellent conductivity and high flexibility, while the graphene composite material effectively enhances the mechanical strength and conductivity stability of the longitudinal electrodes. This allows the electrode layer 2, after being composited, to effectively avoid breakage during bending while maintaining good conductivity. The transverse and longitudinal electrodes are arranged in an interleaved embedded structure, and an arc-shaped transition structure is set at the connection between the transverse and longitudinal electrodes to reduce stress concentration points and lower the risk of breakage due to bending at the connection between the transverse and longitudinal electrodes.

[0016] Please see Figure 1 , Figure 3As shown, a stress buffer layer 6 is provided between the electrode layer 2 and the protective layer 3. The stress buffer layer 6 includes a first surface layer 7 and a second surface layer 8. The thickness of the first surface layer 7 and the second surface layer 8 is 0.1mm-0.3mm, and both the first surface layer 7 and the second surface layer 8 are made of silicone material. Silicone is soft and has good elasticity, thus ensuring the resilience of the stress buffer layer 6. A filling space is provided between the first surface layer 7 and the second surface layer 8, and multiple elastic particles 9 are provided inside the filling space. The elastic particles 9 are spherical, and the particle size of the elastic particles 9 is 0.5mm-0.8mm. Both the surface layer 7 and the second surface layer 8 have embedded holes 10 for embedding elastic particles 9. The diameter of the embedded holes 10 is smaller than the particle size of the elastic particles 9, so that a small part of the elastic particles 9 is fixed on the first panel and the second panel, while most of them are exposed. When the panel is bent by an external force, the elastic particles 9 will undergo elastic deformation under the action of the external force, thereby dispersing the pressure and playing a buffering role through active deformation, reducing the stress on the electrode layer 2, thus effectively protecting the electrode circuit of the electrode layer 2, avoiding the electrode circuit from breaking or short-circuiting, and ensuring the stability of the panel's touch function.

[0017] In the fabrication of the home appliance control display panel, a flexible substrate layer 1 is first prepared according to design requirements. An inner layer 4 made of a polymer elastic material and an outer layer 5 made of fiber-reinforced material are precisely cut and pre-treated. Then, a high-temperature, high-pressure bonding process is used to tightly bond the two layers, forming a flexible substrate layer 1 with high strength and good elasticity. Next, an electrode layer 2 is prepared on the flexible substrate layer 1 using advanced coating and photolithography processes. Silver nanowires and graphene are mixed in a certain proportion to form the electrode material. Lateral and longitudinal electrodes are arranged in an interleaved embedding structure, ensuring an arc-shaped transition structure at the connection points between the electrodes. To improve the flexibility and bending resistance of electrode layer 2, a first surface layer 7 and a second surface layer 8 are formed by compression molding. Both are made of silicone material, and an adhesive layer is applied to them. Then, pre-prepared elastic particles 9 are placed between the two, allowing the elastic particles 9 to roll into the recessed holes 10 and adhere firmly. The first surface layer 7 and the second surface layer 8 are then aligned and bonded together to form a stress buffer layer 6. The stress buffer layer 6 is then tightly bonded to electrode layer 2 using adhesive. Finally, a transparent parylene material is coated on the stress buffer layer 6, and after curing, a protective layer 3 is formed, completing the preparation of the entire home appliance control display panel.
