[0002] A backlight module, also known as a backlight unit or a backlight module, is an important component in a liquid crystal display device. Since the liquid crystal panel itself does not emit light, it needs to rely on the backlight module to provide light sources so that the images and texts on the liquid crystal panel can be clearly displayed. Since the light emitted by the LED lights as light sources is not uniform, in the backlight module, there will be a display phenomenon of uneven brightness and darkness in front of the LED lights, resulting in the light emitted by the LED lights not being fully scattered to the optical components, which affects the display effect of the liquid crystal display device.

FPC; DETAILED DESCRIPTION OF THE EMBODIMENTS

[0022] To facilitate the understanding of the present utility model, the present utility model will be described more comprehensively below with reference to the relevant drawings.

[0023] Please refer to Figures 1 to 3 Figures 1 to 3 , a backlight module 10 for optimizing the display effect, includes: a backlight frame 100 and an optical component 200. The optical component 200 is disposed on the backlight frame 100. A light source area 110 is provided on the backlight frame 100. A plurality of LED lights 120 are provided on the light source area 110. A first diffusion film layer 121 and a scattering film layer 122 are sequentially disposed on the light-emitting surface of the LED light 120. The light-emitting surface of the LED light 120 faces the direction of the optical component 200.

[0024] It should be noted that by disposing the first diffusion film layer 121 and the scattering film layer 122 on the light-emitting surface of the LED light 120, the first diffusion film layer 121 increases the light radiation area, making the light emitted by the LED light 120 more uniform. The scattering film layer 122 can improve the light-emitting effect of the LED light 120 and further improve the uniformity of the light emitted by the LED light 120. With this setting, the display phenomenon of uneven brightness of the light emitted by the LED light 120 is avoided, enabling the light emitted by the LED light 120 to be fully scattered onto the optical component 200 and improving the display effect of the liquid crystal display device.

[0025] Please refer to Figure 2 Figure 2 , in one embodiment, the first diffusion film layer 121 and the scattering film layer 122 are aligned, thereby giving full play to the functions of the diffusion film layer and the scattering film layer 122 and avoiding light loss of the LED light 120.

[0026] Please refer to again Figure 2 Figure 2 , in one embodiment, the thickness of the first diffusion film layer 121 is the same as that of the scattering film layer 122. With this setting, the uniformity of light scattering can be further improved.

[0027] Please refer to Figure 3 Figure 3 , in one embodiment, the optical component 200 includes a reflection film 210, a light guide plate 220, a second diffusion film layer 230, a lower brightness enhancement film layer 240, and an upper brightness enhancement film layer 250 that are sequentially stacked. With this setting, the uniformity and brightness of the light scattered onto the optical component 200 are improved.

[0028] Please refer to again Figure 3 Figure 3 , in one embodiment, an adhesive layer is provided between the reflection film layer 210 and the light guide plate 220, making the connection between the reflection film layer 210 and the light guide plate 220 more stable, avoiding displacement between the reflection film layer 210 and the light guide plate 220, and improving the utilization rate of light.

[0029] Please refer to again Figure 1, in one embodiment, there are a total of sixteen LED lights 120, which are evenly distributed on the light source area 110, making the light distribution of the backlight module 10 more uniform and avoiding the phenomenon of uneven brightness.

[0030] Please refer to again Figure 1 , in one embodiment, it further includes an FPC 300. One end of the FPC 300 is connected to the backlight frame 100. The FPC 300 has flexibility, which is convenient for the backlight module 10 to be connected to other components.

[0031] Please refer to again Figure 1 , in one embodiment, the backlight frame 100 includes a metal frame and a plastic frame. The plastic frame is disposed inside the metal frame. The metal frame provides high stability for the overall structure of the backlight module 10. The stainless steel frame has high strength. Preferably, a stainless steel frame is used as the metal frame. The plastic frame provides a buffering effect for the optical components 200 and the LED lights 120, avoiding the change of the positions of the optical components 200 and the LED lights 120 due to vibration, which may lead to a reduction in the display effect of the liquid crystal display module.

[0032] The above embodiments only represent several implementation manners of the present invention, and the description thereof is relatively specific and detailed, but it should not be construed as a limitation to the scope of the utility model patent. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several deformations and improvements can still be made, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the utility model patent shall be subject to the appended claims.
