[0004] The aforementioned patents can solve the corresponding technical problems and effectively reduce costs. However, the backlight module in the aforementioned brightness enhancement LCD module has poor heat dissipation during use. Poor heat dissipation will cause the temperature of the backlight source, such as LED, to rise, thereby reducing its luminous efficiency and lifespan. As the temperature rises, the luminous intensity of the LED will gradually decrease, and the color of the emitted light may also change. All of these will affect the brightness enhancement effect of the brightness enhancement module. At the same time, high temperature will also accelerate the aging of LED, shorten its lifespan, and increase the cost and frequency of replacing the backlight source. Utility Model Content

[0025] The following will describe in detail the implementation of this application with reference to the accompanying drawings and embodiments, so that the implementation process of how this application uses technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.

[0026] Example

[0027] Please refer to Figures 1 to 3 As shown, this embodiment provides an electronic screen brightness enhancement module, including: a brightness enhancement film 1, a diffuser 2, a light guide plate 3, a reflector 5, and a mounting frame 6, which are installed on the back of the electronic screen and arranged sequentially from top to bottom. LED power supplies 4 are installed at both ends of the light guide plate 3. The top of the mounting frame 6 has a mounting groove 601, and the brightness enhancement film 1, diffuser 2, light guide plate 3, LED power supplies 4, reflector 5, and mounting frame 6 are all installed inside the mounting groove 601. A heat sink is installed on the mounting frame 6, and the reflector 5 is in contact with the heat sink. The heat sink can increase the heat dissipation effect of the entire brightness enhancement module, ensuring that the components of the brightness enhancement module will not deform, age, or degrade due to excessive temperature, thereby providing a brighter light source for the brightness enhancement module and achieving an enhanced brightness enhancement effect.

[0028] The heat sink includes multiple heat sinks 602, which are distributed on the side wall and inner bottom of the mounting groove 601. The heat sinks 602 are fixedly connected to the mounting frame 6. One end of the heat sink 602 is flush with the inner wall of the mounting groove 601, and the other end is flush with the outer wall of the mounting groove 601. The inner end of the heat sink 602 is in contact with the reflector 5. The heat sink 602 is made of copper, and the mounting frame 6 is made of aluminum alloy. The copper structure helps to reduce the weight of the entire electronic device and has a certain heat dissipation performance. By installing the copper heat sink 602 on the mounting frame 6, the heat dissipation effect of the entire brightness enhancement module can be increased. This ensures that the components of the brightness enhancement module will not deform, age, or degrade due to excessive temperature. It also keeps the brightness enhancement film 1 flat, ensuring its efficient light processing and maintaining the stable performance of the brightness enhancement module. In addition, good heat dissipation can reduce the operating temperature of the LED power supply 4, improve its luminous efficiency, and thus provide a brighter light source for the brightness enhancement module, thereby enhancing the brightness enhancement effect.

[0029] The inner end face of the heat sink 602 is coated with a thermally conductive coating 603. The thermally conductive coating 603 can increase the heat conduction and heat dissipation effect of the heat sink 602, which helps the heat dissipation of this brightness enhancement module.

[0030] Among them, the thermally conductive coating 603 is a heat-dissipating silicone grease. The heat-dissipating silicone grease has good fluidity and stability. It can fill the tiny gap between the heat sink 602 and the reflector 5, so that the heat sink 602 and the reflector 5 can form a good contact, thereby improving the heat transfer efficiency.

[0031] The thermal grease should be applied to a thickness of 0.1-0.2 mm, with 0.1 mm being the preferred thickness for effective heat transfer.

[0032] The mounting slot 601 has several heat dissipation holes 604 at its inner bottom, which can further increase the heat dissipation effect inside the mounting slot 601.

[0033] Among them, the reflector 5 is a glass structure with a silver coating on its surface. The silver coating structure of the reflector 5 has a good reflective effect, which can improve the utilization efficiency of light, thereby improving the brightness and uniformity of the backlight module. In addition, the silver coating structure of the reflector 5 has a good thermal conductivity, which can effectively transfer the heat generated by the light guide plate 3 and the LED power supply 4 to the heat sink 602, further increasing the heat dissipation effect of the brightness enhancement module.

[0034] As is well known to those skilled in the art, the working principle and wiring method of LED power supply 4 are commonplace and are all conventional methods or common knowledge. Therefore, they will not be described in detail here. Those skilled in the art can select any model according to their needs or convenience.

[0035] Working principle: The electronic screen is fitted and snapped into the mounting slot 601 of the mounting frame 6, and the electronic screen is located above the brightness enhancement film 1.

[0036] During use, the brightness enhancement film 1 can utilize the principles of light interference, total internal reflection, and refraction to improve the brightness of the backlight module, enhance the uniformity of brightness, reduce the difference in brightness between different areas of the screen, and improve image quality. The diffuser 2 can cause light to undergo refraction, reflection, and scattering when it passes through, thereby diffusing the light and making the light distribution more uniform. The light guide plate 3 guides the light emitted by the side LED power supply 4 to the front of the panel, so that the light can be emitted more uniformly from the light-emitting surface of the light guide plate, thereby improving the brightness and uniformity of the screen. The reflector 5 can completely send the light emitted by the LED power supply 4 into the light guide plate 3, minimize unnecessary losses, and make the light reused by reflecting the light, thereby improving the brightness of the screen.

[0037] During the use of the brightness enhancement module, a copper heat sink 602 is installed on the mounting frame 6. The heat sink 602 can absorb heat and transfer it to the outside of the mounting frame 6, thereby achieving the effect of heat dissipation for the components inside the mounting groove 601. This ensures that the components of the brightness enhancement module will not deform, age, or degrade due to excessive temperature, keeping the brightness enhancement film 1 flat and ensuring its efficient light processing. This maintains the stable performance of the brightness enhancement module. In addition, good heat dissipation can reduce the operating temperature of the LED power supply 4, improve its luminous efficiency, and thus provide a brighter light source for the brightness enhancement module, thereby enhancing the brightness enhancement effect.

[0038] The foregoing description illustrates and describes several preferred embodiments of the present invention. However, as previously stated, it should be understood that the present invention is not limited to the forms disclosed herein and should not be construed as excluding other embodiments. It can be used in various other combinations, modifications, and environments, and can be altered within the scope of the inventive concept described herein through the foregoing teachings or techniques or knowledge in related fields.
