[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0019] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0020] Example 1 This utility model discloses a display module with heat dissipation and buffering capabilities. (Refer to...) Figure 1 ,include: Display screen 1, with a cuboid structure, is used to provide display content; flexible blocks 3 are attached to the four sides of display screen 1, completely covering the four sides of display screen 1, and the flexible blocks 3 are elastic; alumina powder layer 31 is attached to the outside of flexible blocks 3 along the four sides of display screen 1, completely covering the outside of flexible blocks 3, and the alumina powder layer 31 is thermally conductive; backlight panel 4, with a cuboid shape and a groove 41, is placed in the groove 41, and the display screen 1, flexible blocks 3, and alumina powder layer 31 are all placed in the groove 41, with the four inner sides of the groove 41 in contact with the alumina powder layer 31, and the thickness of backlight panel 4 is greater than the thickness of display screen 1; the depth of groove 41 is the same as the height of display screen 1; coated cover plate 2 completely covers the upper surface of display screen 1 and backlight panel 4, and is used to protect display screen 1, and the area of ​​coated cover plate 2 is the same as the area of ​​backlight panel 4.

[0021] Based on the above structure, the display screen 1 is a device that provides display content. The image to be displayed is generated and projected on the display screen 1. The coated cover plate 2 covers the display screen 1 and can effectively protect the side of the display screen 1 facing the viewer, that is, the coated cover plate 2 effectively protects the side of the display screen 1 that emits the display content. In order to reduce the damage caused by the display screen 1 to impacts during drops or bumps, flexible blocks 3 are placed around the display screen 1. Since the upper surface of the display screen 1 needs to project the display content, the flexible blocks 3 cannot be placed on the upper surface, otherwise it will block the display content. Flexible blocks 3 can be placed around the display screen 1. The flexible blocks 3 have a certain degree of elasticity. When the display screen 1 is bumped, the flexible blocks 3 around the display screen 1 will absorb energy, thereby protecting the display screen 1 from damage.

[0022] Optionally, wrapping the flexible block 3 may cause the heat dissipation effect of the display screen 1 to deteriorate. Therefore, an aluminum oxide powder layer 31 is provided on the outside of the flexible block 3. The aluminum oxide powder layer 31 has strong thermal conductivity, which can greatly increase the heat dissipation of the flexible block 3 to the outside, thereby increasing the heat dissipation effect of the display screen 1.

[0023] Optionally, the backlight plate 4 is the light source carrier of the display screen 1. The backlight plate 4 is set below the display screen 1 to effectively reflect the required light source to the display screen 1. A groove 41 is set on the backlight plate 4, and the display screen 1, the flexible block 3 and the alumina powder layer 31 are all placed in the groove 41. On the one hand, the light source is concentrated and reflected onto the display screen 1, and on the other hand, the flexible block 3 and the alumina powder are fixed around the display screen 1 to prevent them from moving relative to the display screen 1.

[0024] Optionally, by setting a coated cover plate 2, the upper surface of the display screen 1 can be effectively protected, scratches and wear can be reduced, and the visual experience of the viewer can be improved. A flexible baffle 3 can be set to absorb the energy of the force when the display screen 1 is bumped, effectively preventing damage to the display screen 1 after being bumped. The high thermal conductivity of the alumina powder layer 31 improves the thermal conductivity of the flexible baffle 3, thereby improving the heat dissipation effect of the display screen 1.

[0025] In this preferred embodiment, the flexible block 3 is an organic silicone flexible block; the thickness of the alumina powder layer 31 is 5 micrometers.

[0026] Based on the above structure, the edge of display screen 1 is a weak point and is prone to breakage due to impact or compression. Silicone combines "deformation capability" and "resilience." When the display module is subjected to external forces such as drops or collisions, the silicone can absorb the impact through "compression deformation," and can quickly return to its original shape after deformation, without permanent deformation due to long-term compression.

[0027] Optionally, silicone has good plasticity and surface wettability, which can fit tightly against the side of the display screen 1 and the alumina powder layer 31 during assembly. It can completely fill the tiny gap between the display screen 1 and the groove 41 of the backlight plate 4, "suspending and fixing" the display screen 1 in the center of the groove 41, avoiding cable wear or display offset caused by shaking during use.

[0028] Alternatively, alumina (Al2O3) has a thermal conductivity of approximately 30-40 W / (m²). K) (far higher than the 0.2-0.4 W / (m) of silicone) The 5μm thickness is sufficient to meet the local heat dissipation needs around the display screen 1. The heat of the display screen 1 is mainly concentrated in the driver chip and ribbon cable area. After being conducted to the surface through the silicone, the 5μm aluminum oxide powder layer 31 can quickly "laterally diffuse" the heat to the inner wall of the groove 41 of the backlight plate 4 (the backlight plate 4 is a large-area heat dissipation carrier), avoiding chip overheating and display lag caused by local heat accumulation.

[0029] In this preferred embodiment, the display module further includes: a double-sided adhesive 11, which has adhesive on both sides, one side is attached to the lower surface of the chromium carbide layer 24, completely covering the chromium carbide layer 24; the other side covers the upper surface of the backlight panel 4, the flexible block 3, and the alumina powder layer 31; the area of ​​the double-sided adhesive 11 is sufficient to cover the upper surface of the backlight panel 4, the flexible block 3, and the alumina powder layer 31.

[0030] Based on the above structure, referring to Figure 1To ensure a secure connection between the coating cover plate 2, the display screen 1, and the backlight plate 4, and to prevent separation or shaking, double-sided adhesive 11 is used to fix them. One side of the double-sided adhesive 11 is pasted on the coating cover plate 2, and the other side is pasted on the backlight plate 4, extending from the edge of the backlight plate 4 to the display screen 1.

[0031] Optionally, by using double-sided adhesive 11 to attach the edge of the backlight panel 4, the alumina powder layer 31, the flexible block 3, and the display screen 1 to one side of the backlight panel 4, all the above components can be relatively fixed to prevent displacement during use.

[0032] In this preferred embodiment, the coated cover plate 2 includes: a glass cover plate 21 that completely covers the upper surfaces of the display screen 1 and the backlight panel 4, the area of ​​the glass cover plate 21 being the same as the area projected onto the upper surface of the backlight panel 4; the glass cover plate 21 includes a visible area and a non-visible area, the visible area being the area where the display screen 1 is projected onto the glass cover plate 21, and the non-visible area being located around the visible area; and a thermochromic ink layer 22 disposed below the glass cover plate 21 and completely covering the non-visible area.

[0033] Based on the above structure, referring to Figure 2 and Figure 3 The coated cover plate 2 is the best barrier to protect the display screen 1. The visible area corresponding to the coated cover plate 2 needs to be light-transmitting and colorless transparent to avoid obstructing the display content of the display screen 1. Therefore, the glass cover plate 21 is more suitable. The glass cover plate 21 is transparent and has a certain strength to resist impact damage, and is also wear-resistant.

[0034] Optionally, to cover the lines in the non-visible area, such as the backlight panel 4 and flexible block 3 around the display screen 1, a thermochromic ink layer 22 can be set in the non-visible area. The thermochromic ink can change color according to temperature changes, increasing the fun and interactivity of the product. At the same time, the screen printing process is flexible and can design a variety of patterns and colors, improving the aesthetics of the product.

[0035] In this preferred embodiment, the coated cover plate 2 further includes: an aluminum bronze alloy layer 23, which is disposed on the lower surface of the thermochromic ink layer 22, completely covering the thermochromic ink layer 22, and has wear resistance; the thickness of the aluminum bronze alloy layer 23 is 30 nanometers to 40 nanometers.

[0036] Based on the above structure, referring to Figure 3 The aluminum bronze alloy layer 23 is placed below and adjacent to the thermochromic ink layer 22. With its high hardness and good corrosion resistance, the aluminum bronze alloy layer 23 effectively prevents the thermochromic ink layer 22 from being scratched, providing a solid protective barrier for the thermochromic ink layer 22.

[0037] Optionally, in order to control the overall thickness of the coated cover plate 2 while ensuring its protection of the thermochromic ink layer 22, the thickness of the aluminum bronze alloy layer 23 is set to 30 nanometers to 40 nanometers.

[0038] In this preferred embodiment, the coated cover plate 2 further includes: a chromium carbide layer 24, disposed on the lower surface of the aluminum bronze alloy layer 23, completely covering the aluminum bronze alloy layer 23, for protecting the aluminum bronze alloy layer 23; the thickness of the chromium carbide layer 24 is 15 nanometers to 25 nanometers.

[0039] Based on the above structure, the chromium carbide (Cr3C2) layer is disposed under the aluminum bronze alloy layer 23 as the innermost protective layer, further enhancing the overall wear resistance and chemical stability, providing additional protection for the thermochromic ink layer 22 and the aluminum bronze alloy layer 23, and ensuring the long-term stability of the entire coating structure.

[0040] In this preferred embodiment, the coated cover plate 2 further includes: a nickel-based alloy layer 25, disposed on the upper surface of the glass cover plate 21, with an area equal to that of the glass cover plate 21, and having corrosion resistance; the thickness of the nickel-based alloy layer 25 is 20 nanometers to 30 nanometers.

[0041] Based on the above structure, referring to Figure 3 The nickel-based alloy layer 25 is made of Ni-B-Si alloy and is located above the glass cover plate 21, facing the viewer. Ni-B-Si alloy is a nickel-based alloy with self-fluxing characteristics. With its unique physical and chemical properties, Ni-B-Si alloy provides additional hardness, wear resistance and corrosion resistance, further protecting the surface of the glass cover plate 21 and ensuring the long-term stability of the coating layer.

[0042] In this preferred embodiment, the coated cover plate 2 further includes: a tin bronze alloy layer 26 disposed on the upper surface of the nickel-based alloy layer 25, which has wear resistance; the thickness of the tin bronze alloy layer 26 is 20 nanometers to 30 nanometers.

[0043] Based on the above structure, the tin bronze alloy layer 26 has good corrosion resistance and a certain degree of hardness, which can further enhance the protective performance of the glass cover 21 and work synergistically with the nickel-based alloy layer 25 to improve overall durability.

[0044] In this preferred embodiment, the coated cover plate 2 further includes a cobalt-chromium-tungsten alloy layer 27, disposed on the upper surface of the tin bronze alloy layer 26, for protecting the tin bronze alloy layer 26; the thickness of the cobalt-chromium-tungsten alloy layer 27 is 30 nanometers to 50 nanometers.

[0045] Based on the above structure, the cobalt-chromium-tungsten alloy layer 27 provides high hardness, high strength and excellent wear resistance, significantly improving the scratch resistance and wear resistance of the glass cover plate 21 surface, while also having good chemical stability and corrosion resistance.

[0046] Example 2 The present invention provides a display device, including a display module for heat dissipation and buffering.

[0047] The implementation principle of the heat dissipation and buffering display module and display device of this utility model embodiment is as follows: First, a cobalt-chromium-tungsten alloy layer 27 is used as the outermost layer, effectively resisting external scratches and wear due to its high hardness, high strength, and excellent wear resistance. Subsequently, a tin bronze alloy layer 26 and a Ni-B-Si alloy layer serve as intermediate layers, further enhancing the overall hardness and corrosion resistance, forming a robust protective barrier. A glass cover plate 21 serves as the base, ensuring structural stability and transparency. On the back of the glass cover plate 21, the application of a thermochromic ink layer 22 not only increases the product's fun and interactivity but also enhances its aesthetics through flexible screen printing. Finally, an aluminum bronze alloy and chromium carbide layer 24 serve as the inner protective layer, preventing scratches on the ink layer and improving overall chemical and thermal stability.

[0048] By precisely controlling the combination and thickness of the multi-layer coating materials, the performance of the glass cover 21 is fully optimized. The combined effect of this multi-layer coating structure enables the glass cover 21 to maintain high transparency while possessing excellent wear resistance, corrosion resistance and high temperature resistance, meeting the stringent requirements of high-end electronic products for cover performance and effectively protecting the upper surface of the display screen 1.

[0049] The above are all preferred embodiments of this utility model, and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape and principle of this utility model should be covered within the scope of protection of this utility model.
