Description

Technical Field

[0001] This utility model relates to the field of aluminum alloy sheet technology, and in particular to an aluminum alloy sheet used in screen backlight panels. Background Technology

[0002] Aluminum alloys are alloys based on aluminum with added amounts of other alloying elements, and are one type of lightweight metal material. In addition to the general properties of aluminum, aluminum alloys also possess specific alloying characteristics due to variations in the types and amounts of alloying elements added. The density of aluminum alloys ranges from 2.63 to 2.85 g / cm³. 3 It has high strength (σb is 110~650MPa), specific strength close to that of high alloy steel, specific stiffness exceeding that of steel, good casting and plastic processing properties, good electrical and thermal conductivity, good weldability, and can be used as a structural material. It has wide applications in aerospace, aviation, transportation, construction, electromechanical, electronics, light chemical and daily necessities fields.

[0003] Currently, aluminum alloy sheets are typically single-layer structures, and are generally used in production and use. While this type of sheet has a simple structure, its function is relatively limited. When used as a screen backlight panel, light is scattered and absorbed on the aluminum alloy sheet, resulting in low reflectivity, low screen brightness, and low light efficiency, thus affecting the user's visual experience. Furthermore, aluminum alloy sheets have poor heat dissipation performance, leading to lower product quality. Overheating can cause screen performance degradation, affecting normal screen operation and shortening the screen's lifespan, failing to meet current requirements. Therefore, it is necessary to research a new technical solution to improve current aluminum alloy sheets. Utility Model Content

This material can effectively solve the problems of existing aluminum alloy sheets having relatively limited functions, scattering and absorption of light when used as screen backlight panels, low light reflectivity leading to low screen brightness and low light efficiency, which affects the user's visual experience, poor heat dissipation performance, poor product quality, and high screen temperature which can easily lead to screen performance degradation, affecting normal screen operation and short screen lifespan.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] An aluminum alloy sheet for a screen backlight panel includes a main body, a heat dissipation layer, and a reflective layer. The main body includes a base layer, a buffer layer, a corrosion-resistant layer, and a wear-resistant layer. The buffer layer is stacked on the upper surface of the base layer, effectively enhancing the product's buffering performance and providing cushioning against vibrations to prevent damage to the sheet.

The wear-resistant layer is stacked on the lower surface of the corrosion-resistant layer, effectively enhancing the product's wear resistance, preventing scratches from damaging the sheet, improving product quality, and extending product lifespan. The heat dissipation layer covers the upper surface and outer peripheral surfaces of the main body, effectively enhancing the product's heat dissipation performance and enabling rapid heat dissipation from the screen backlight module. The reflective layer is stacked on the upper surface of the heat dissipation layer, which helps to increase light reflectivity, improve the brightness of the backlight module, and enhance light efficiency.

[0007] As a preferred embodiment, the upper surface of the reflective layer is provided with multiple protrusions, which are evenly spaced to further improve the reflectivity of light, enhance the reflection effect, and improve the uniformity of light and the overall brightness of the backlight module.

[0016] Compared with the prior art, this utility model has obvious advantages and beneficial effects. Specifically, as can be seen from the above technical solution:

[0017] By covering the upper surface and outer periphery of the main body with a heat dissipation layer, the product's heat dissipation performance is effectively enhanced, improving product quality. This allows for rapid heat dissipation from the screen backlight module, ensuring stable screen performance, guaranteeing normal screen operation, and extending screen lifespan. Furthermore, by stacking a reflective layer on the upper surface of the heat dissipation layer, the reflectivity of light is effectively increased, improving screen brightness, light efficiency, and enhancing the user's visual experience. The addition of a buffer layer, corrosion-resistant layer, and wear-resistant layer further enhances the product's buffering, corrosion resistance, and wear resistance, resulting in richer and more diverse functions to meet current needs.

[0029] The heat dissipation layer 20 is disposed on the upper surface and the outer peripheral side of the main body 10, which effectively enhances the heat dissipation performance of the product and enables the heat of the screen backlight module to be dissipated quickly. In this embodiment, the heat dissipation layer 20 is made of graphene, which has a good heat dissipation effect.

[0030] The reflective layer 30 is stacked on the upper surface of the heat dissipation layer 20, which helps to improve the reflectivity of light, increase the brightness of the backlight module, and improve the light efficiency. In this embodiment, the upper surface of the reflective layer 30 is provided with a plurality of protrusions 31, which are evenly spaced to further improve the reflectivity of light, enhance the reflection effect, and improve the uniformity of light and the overall brightness of the backlight module. Specifically, the cross-section of the protrusion 31 is arc-shaped. The reflective layer 30 is a mirror-plated silver layer, which effectively improves the reflectivity of light.
