Description

Technical Field

[0001] This utility model relates to the field of OLED display technology, specifically to an adaptive OLED display with a temperature control structure. Background Technology

[0002] OLED (Organic Light Emitting Diode) display is a display technology that uses organic materials to emit light under the influence of an electric field. The core principle is that each pixel on an OLED screen is composed of tiny, independently emitting organic material diodes. When current passes through, these organic materials emit light.

[0003] A search revealed a Chinese patent (CN220874974U) disclosing a high-efficiency heat dissipation OLED display screen. The screen includes an OLED display body with heat dissipation grooves on both sides. A heat dissipation structure is installed inside each groove. A glass plate is embedded in the top of the OLED display body, and a cooling fan is embedded in the bottom. A temperature-sensing switch is embedded in the center of the bottom inner wall of the OLED display body. Mounting seats are located on both sides of the bottom inner wall of the OLED display body, and a cooling plate is installed between the inner sides of the mounting seats. A metal anode is installed on the top of the mounting seats. The overall structure is simple, facilitating heat dissipation from both sides and bottom temperature control absorption, thus enabling efficient multi-directional heat dissipation of the OLED display screen. It also exhibits high stability and practicality, making it worthy of widespread application.

[0004] However, in actual use, it was found that the above-mentioned patents mainly involve opening heat dissipation slots on both sides of the display screen, installing heat dissipation fans and heat dissipation structures. The structure is complex and heavy. Moreover, the heat dissipation fans are mechanical moving parts that require power supply, which increases the power consumption. In addition, they generate noise and vibration during operation. Therefore, we propose an adaptive OLED display screen with a temperature control structure. Utility Model Content

[0005] The technical problem to be solved by this application is that the above-mentioned patent mainly involves opening heat dissipation slots on both sides of the display screen, installing heat dissipation fans and heat dissipation structures. Its structure is complex and heavy. Moreover, the heat dissipation fan is a mechanical moving part that requires power supply, which increases the additional power consumption. In addition, it will generate noise and vibration when running.

[0006] To address the aforementioned technical problems, this application provides an adaptive OLED display screen with a temperature control structure, comprising a display housing and internal electronic components. An aerogel layer is bonded to the outer side of the electronic components. A heat-conducting sheet is bonded to one end of the aerogel layer and the electronic components. A diamond layer is bonded to one end of the heat-conducting sheet. A graphene propylene layer is wrapped around the outer side of the diamond layer and the aerogel layer. Multiple pentagonal grid grooves that are equidistantly distributed on the outer side of the aerogel layer and whose lower ends are bonded to the diamond layer are interconnected. Multiple tapered through holes are equidistantly distributed on the outer side of the heat-conducting sheet. A shape memory alloy body is disposed inside the through holes.

[0007] In some embodiments, a radial microgroove is formed at one end of the diamond layer, and a radial electrode is attached to the inside of the microgroove.

[0008] In some embodiments, the side where the aerogel layer and the diamond layer are bonded has a bevel.

[0009] In some embodiments, multiple fins are equidistantly mounted on both sides of the graphene propylene layer that are flush with one end of the display housing, and the fins extend in an L-shape to both ends of the display housing.

[0010] In some embodiments, the shape memory alloy body is composed of a plurality of tightly fitted shape memory alloy sheets in a pointed cone shape.

[0011] In some embodiments, nanoparticle fillers are uniformly embedded on the outer side of the diamond layer.

[0012] In some embodiments, the outer side of the radial electrode is plated with an iridium layer.

[0013] This utility model has at least the following beneficial effects:

[0014] 1. The aerogel layer has pentagonal grid grooves to directionally confine the heat of electronic components to the heat-conducting sheet, blocking lateral heat diffusion. Its density reduces the weight of the display screen, provides insulation protection, and has a certain degree of elasticity to support the substrate. Heat is physically dissipated through the heat-conducting sheet, diamond layer and graphene propylene layer.

[0015] 2. Conical through holes are set on the heat-conducting sheet to provide deformation space for the expansion of the shape memory alloy and to convert shear stress into axial pressure, thus preventing the diamond layer from cracking.

[0016] 3. A shape memory alloy body is placed in the through hole. When the temperature is greater than 45 degrees, the shape memory alloy cone undergoes axial phase change expansion, which pushes the heat-conducting plate to fit tightly with the diamond layer, causing the interface pressure to rise and the thermal resistance to decrease. At the same time, the expansion of the cone reduces the cross-sectional area of ​​the through hole, triggering the Venturi effect (a side effect), thus achieving temperature adaptive control.

Detailed Implementation

[0026] 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.

[0027] Example 1: Please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 6 and Figure 8This utility model provides a technical solution: an adaptive OLED display screen with a temperature control structure, including a display shell 1 and an electronic component 2 inside it. An aerogel layer 3 is attached to the outside of the electronic component 2. A heat-conducting sheet 4 is attached to one end of the aerogel layer 3 and the electronic component 2. A diamond layer 5 is attached to one end of the heat-conducting sheet 4. A graphene propylene layer 6 is wrapped around the outside of the diamond layer 5 and the aerogel layer 3. Multiple pentagonal grid grooves 7 are equidistantly opened on the outside of the aerogel layer 3, which are interconnected and whose lower ends are attached to the diamond layer 5. Multiple conical through holes 8 are equidistantly opened on the outside of the heat-conducting sheet 4. A shape memory alloy body 9 is provided inside the through holes 8.

[0028] Electronic component 2 adopts a stacked structure design: glass plate 201 is embedded in the end of the outer shell 1, and anode 202, light-emitting layer 203, conductive layer 204, cathode 205 and substrate 206 are laminated in sequence. The substrate 206 is directly thermally coupled to the heat-conducting sheet 4. This structure realizes the integration of photoelectric conversion and heat conduction path.

[0029] The aerogel layer 3 acts as a thermal insulation barrier. The pentagonal grid grooves 7 on the aerogel layer 3 can directionally confine the heat of the electronic component 2 to the heat-conducting sheet 4, preventing the heat of the electronic component 2 from spreading to non-heat dissipation areas, while providing elastic support. The aerogel layer 3 is a lightweight insulator, which can reduce the overall weight of the display screen and provide electrical insulation. The heat of the electronic component 2 is directed to the graphene propylene layer 6 through the heat-conducting sheet 4 and the diamond layer 5 to achieve physical heat dissipation. Compared with the method of opening heat sinks, heat dissipation fans, installing heat dissipation fans and heat dissipation structures, the overall weight is low and no additional power consumption is required.

[0030] The side where the aerogel layer 3 and the diamond layer 5 are bonded together is provided with a bevel 12. By setting the bevel 12, the aerogel layer 3 and the heat-conducting sheet 4 form a progressive contact area, which avoids the aerogel layer 3 from breaking due to hard contact with the heat-conducting sheet 4 and eliminates the difference in thermal expansion coefficient of the diamond layer 5.

[0031] The shape memory alloy body 9 is composed of multiple tightly fitted cone-shaped shape memory alloy sheets. When the temperature is greater than 45 degrees, the cone of the shape memory alloy body 9 undergoes axial phase change expansion, which pushes the heat-conducting sheet 4 to fit tightly with the diamond layer 5, causing the interface pressure to rise and the thermal resistance to decrease. At the same time, the expansion of the cone reduces the cross-sectional area of ​​the through hole 8, triggering the Venturi effect (a side effect), thus achieving temperature adaptive control.

[0032] During use, the heat of electronic component 2 is blocked by aerogel layer 3 and physically dissipated from graphite propylene layer 6 to the outside of display housing 1 through grid groove 7, heat-conducting sheet 4, and diamond layer 5.

[0033] Nanoparticle fillers are uniformly embedded on the outer side of the diamond layer 5. The nanoparticle fillers have negative expansion characteristics, which can compensate for the thermal difference between the diamond layer 5 and the substrate 206. They can also induce a pinning effect in the crack propagation path of the diamond layer 5, thus inhibiting cracks in the diamond layer 5.

[0034] Example 2: Based on Example 1, as follows Figure 5 As shown, a radial microgroove 10 is formed at one end of the diamond layer 5. A radial electrode 11 is attached inside the microgroove 10. An iridium layer is plated on the outside of the radial electrode 11. By passing current through the electrode 11, the local temperature of the diamond layer 5 can be increased, thus avoiding premature shrinkage of the shape memory alloy body 9 and the resulting surge in low-temperature interface thermal resistance.

[0035] Example 3: Based on Example 2, such as Figure 7 As shown, multiple fins 13 are equidistantly mounted on both sides of the graphene propylene layer 6, which is flush with one end of the display housing 1. The fins 13 extend in an L-shape to both ends of the display housing 1, thereby increasing the contact area and improving the heat dissipation effect.
