[0025] This application provides an energy-saving direct-lit MiniLED backlight, effectively solving the problems of insufficient light processing, limited color performance, and heavy structure of traditional direct-lit MiniLED backlights. This energy-saving direct-lit MiniLED backlight achieves optimized light processing through the synergistic effect of its various layers, resulting in excellent energy saving, uniformity, high brightness, and high color performance. This not only improves display quality and provides users with a more realistic and clear visual experience, but also enhances the display's flexibility. The MiniLED backlight is only 0.885mm thick, and the mini LED beads are only 0.130mm thick. The thin and light design makes it more adaptable to the design requirements of thinner and lighter electronic products. The light-shielding adhesive tightly surrounds the edges of each film layer, effectively preventing light leakage and significantly improving the backlight's contrast.

[0026] Example: Figure 1 and Figure 2 As shown, the technical solution in this application embodiment effectively solves the technical problems of traditional direct-lit MiniLED backlights, such as insufficient light processing, limited color performance, and a relatively bulky structure. The overall idea is as follows:

[0027] To address the problems existing in the prior art, this utility model provides an energy-saving direct-lit MiniLED backlight, including a glue plate 1, a mini lamp board 2, a QD film 3, a beam splitter 4, a brightness enhancement film 5, and a light-shielding adhesive 6. The glue plate 1 is located at the bottom layer, the mini lamp board 2 is installed inside the glue plate 1, the QD film 3, the beam splitter 4, and the brightness enhancement film 5 are stacked sequentially on top of the mini lamp board 2, and the light-shielding adhesive 6 is located at the outermost layer and is disposed on the glue plate 1 to prevent light leakage.

[0028] The mini lamp board 2 is provided with mini lamp beads arranged in a matrix, and the spacing between the mini lamp beads is uniform to achieve uniform light emission and energy saving.

[0029] The QD film 3 is closely attached to the top of the mini lamp panel 2, and its quantum dot distribution structure can fully interact with the light emitted by the mini lamp panel 2.

[0030] The beam splitter 4 is located above the QD film 3, and the beam splitter 4 is seamlessly connected to the QD film 3 to adjust the propagation direction of light from the QD film 3;

[0031] The light-shielding adhesive 6 tightly surrounds the edges of the QD film 3, the beam-splitting film 4, and the brightness-enhancing film 5, and is in close contact with the adhesive iron 1, the QD film 3, the beam-splitting film 4, and the brightness-enhancing film 5 to prevent light from leaking from the edges.

[0032] Working principle:

[0033] The mini LEDs arranged in a matrix with uniform spacing on the mini LED panel 2 emit light when powered on. The light first shines on the QD film 3 tightly attached above it. The quantum dot distribution structure of the QD film 3 interacts fully with the light, significantly improving the color performance and expanding the color gamut. After being processed by the QD film 3, the light continues to propagate upwards to the beam splitter 4 located above it and seamlessly connected. The beam splitter 4, through its special optical structure, precisely adjusts the direction of light propagation, making the light more concentrated and orderly, thereby improving the utilization rate of the light. Next, the light reaches the brightness enhancement film 5, which, due to its... Its special microstructure design effectively enhances the brightness of the emitted light after passing through the beam splitter 4, making the light brighter and more uniform. Finally, to prevent light from leaking from the edges and affecting the contrast and display effect, the light-shielding adhesive 6 tightly surrounds the edges of the QD film 3, beam splitter 4 and brightness enhancement film 5, limiting the light within an effective range, thereby ensuring the high-quality display effect of the backlight. The entire process works synergistically to achieve an energy-saving, uniform, high-brightness and high-color-performance backlight effect. The thickness of this backlight is 0.885mm, and the thickness of the mini LED beads is 0.130mm.

[0034] Finally, it should be noted that the above embodiments are merely examples for clearly illustrating the present invention and are not intended to limit the implementation. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
