[0002] The backlight is a light source device used to ensure that the back of the LCD screen emits light. Liquid crystal is a non-luminous display device and needs a backlight to achieve its display function. The performance of the backlight will not only directly affect the quality of LCD display, but also account for 10-15% of the cost of the LCD module and 75% of the power consumed by the module. Therefore, it can be said to be a key component in the LCD module.

[0003] The temperature of the existing display backlight will rise after long-term use. If the temperature inside the display rises to a certain level, the fixing glue may melt due to the heat. The main function of the fixing glue is to fix the various components inside the display, such as the backlight, circuit board, etc. When the fixing glue melts, its original fixing function will be greatly weakened or even fail, causing the components inside the display to loosen or shift. If the melting of the fixing glue causes the connection between the components to become unstable, it may further cause structural rupture, especially when subjected to external force or vibration. The risk of such rupture is higher. Therefore, the utility model provides a display backlight that is resistant to high-temperature debonding to meet the needs. Utility Model Content

[0023] The following is a detailed description of a backlight plate for a display screen that is resistant to high-temperature debonding provided by the utility model in combination with the accompanying drawings and specific embodiments. At the same time, it is explained here that in order to make the embodiments more detailed, the following embodiments are the best and preferred embodiments, and those skilled in the art may also adopt other alternative methods to implement some known technologies; and the accompanying drawings are only for a more specific description of the embodiments, and are not intended to specifically limit the utility model.

[0024] like Figures 1 to 3As shown, an embodiment of the utility model provides a backlight panel for a display screen that is resistant to high-temperature debonding, comprising a backlight panel main body 1, a connecting line 2 is arranged on the outside of the backlight panel main body 1, a positioning assembly is used for auxiliary installation of a circuit board, the positioning assembly is connected to the backlight panel main body 1, the positioning assembly comprises four positioning columns 3 connected to the four corners of the backlight panel main body 1, a connecting seat 301 is arranged on the side of the positioning column 3 facing the backlight panel main body 1, a square connecting portion 302 is arranged on the outside of the connecting seat 301, a right-angle inclined support column 303 is fixedly connected to the outside of the connecting portion 302, the bottom end of the right-angle inclined support column 303 is inclined toward the center of the backlight panel main body 1, and the right angle of the right-angle inclined support column 303 faces the backlight panel main body. 1 is provided with an auxiliary fixing piece 305, the top end of the right-angled inclined support column 303 extends outward, and the distance the top end of the right-angled inclined support column 303 extends outward is the same as the distance the bottom end extends inward, the thickness value from the top end to the bottom end of the right-angled inclined support column 303 gradually decreases, and reinforcing ribs 304 are provided on the two right-angled sides facing outward of the right-angled inclined support column 303. During use, first, the backlight panel body 1 is placed in a predetermined installation position to ensure that the backlight panel body 1 is stable and accurately positioned. The circuit board can be initially positioned and fixed by cooperating with the connecting seat 301 and the connecting part 302 on the four positioning columns 3, and the circuit board is further fixed by the design of the right-angled inclined support column 303. The bottom end of the right-angled inclined support column 303 is inclined toward the center of the backlight panel body 1, providing additional support for the circuit board. At the same time, the auxiliary fixing member 305 thereon can be used to fix the circuit board more firmly. Finally, the backlight panel body 1 is connected to other electronic components through the connecting wire 2 to complete the assembly process of the entire display screen. Through the precise design and structural reinforcement of the positioning components, especially the setting of the right-angled inclined support column 303 and its reinforcing ribs 304, the fixing stability between the circuit board and the backlight panel body 1 is significantly enhanced. This design effectively prevents the problem of fixing failure caused by high temperature or other factors, and ensures the long-term stable operation of the display screen. The inclined design of the right-angled inclined support column 303 and the addition of the reinforcing ribs 304 enable the backlight panel body 1 to better disperse and absorb energy when it is impacted or vibrated by external forces, reducing the risk of structural rupture. This is of great significance for improving the overall durability and reliability of the display screen. Although the original design intention of the right-angled inclined support column 303 is not directly aimed at heat dissipation, its inclined structure may help air circulation to a certain extent, thereby indirectly improving the heat dissipation performance of the backlight panel body 1 and its surrounding areas. This helps to reduce the temperature of the backlight panel in a high temperature environment and reduce the melting of the fixing glue due to excessive temperature. The introduction of the positioning component simplifies the installation process of the circuit board, allowing the assemblers to complete the positioning and fixing of the circuit board more quickly and accurately. This improves the assembly efficiency of the production line and reduces labor and time costs.

[0025] In this embodiment, if Figure 4 As shown, the backlight panel body 1 includes a release paper 101, a black and white double-sided tape 102 is adhered to the outer circle of the top of the release paper 101, a polyester film 103 is adhered to the surface of the black and white double-sided tape 102, a PET protective film 104 is provided on the top of the polyester film 103, the white side of the black and white double-sided tape 102 faces the release paper 101, the model of the polyester film 103 is AJ300, a PET base material double-sided tape 105 is adhered to the bottom of the release paper 101, a reflective film 106 is adhered to the bottom of the PET base material double-sided tape 105, the model of the PET base material double-sided tape 105 is TESA4980, and the model of the reflective film 106 is RW100. The PET base material double-sided tape 105 (model TESA4980) firmly adheres the reflective film 106 to the release paper 101 by virtue of its strong adhesive force. The main function of the reflective film 106 (model RW100) is to improve the reflection efficiency of light and increase the brightness of the display screen. The black and white double-sided tape 102 is used to fix the polyester film 103 on the backlight panel body 1, with the white side facing the release paper 101. This design may help to improve the adhesion or meet specific optical requirements. The polyester film 103 (model AJ300) is a key component of the backlight panel. It not only has excellent physical and chemical properties, but also can insulate heat to a certain extent and protect the internal components of the backlight panel from high temperature. The PET protective film 104 covers the polyester film 103, further enhancing the wear resistance and scratch resistance of the backlight panel, and provides an additional protective layer. Although the backlight panel body 1 itself does not directly participate in the generation of heat, its material and structural design help to manage and disperse heat. For example, the heat insulating properties of the polyester film 103 and the PET protective film 104 can reduce the temperature of the backlight panel surface, while the reflective film 106 reduces energy loss and the possibility of conversion into heat by efficiently reflecting light. By adopting high-quality materials and optimized structural design, the backlight panel main body 1 performs well in terms of wear resistance, scratch resistance and high temperature resistance, significantly improving the durability and service life of the display screen. The efficient reflective performance of the reflective film 106 ensures that more light can be effectively utilized, thereby improving the brightness of the display screen, making the picture clearer and more vivid. The presence of the polyester film 103 and the PET protective film 104 provides an additional protective layer for the internal components of the backlight panel, effectively preventing external factors from damaging the internal structure, and ensuring the stable operation of the display screen. Although the backlight panel main body 1 itself does not directly dissipate heat, its material and structural design help to disperse and manage heat, reducing the risk of problems such as melting of the fixing glue due to high temperature.

[0026] The working principle provided by the utility model is that first, the backlight panel body 1 is placed on a predetermined installation position to ensure that the backlight panel body 1 is stable and accurately positioned. The circuit board can be initially positioned and fixed by cooperating with the connecting seat 301 and the connecting part 302 on the four positioning columns 3. The circuit board is further fixed by the design of the right-angle inclined support column 303. The bottom end of the right-angle inclined support column 303 is inclined toward the center of the backlight panel body 1, providing additional support for the circuit board. At the same time, the auxiliary fixing member 305 thereon can be used to fix the circuit board more firmly. Finally, the backlight panel body 1 is connected to other electronic components through the connecting wire 2 to complete the assembly process of the entire display screen.
