  • Mura-Compensable Direct-Lit Mini-LED Backlight Module
    Publication number: 20220236609
    Abstract: The disclosure provides a mura-compensable direct-lit Mini-LED backlight module, including a PCB substrate, a reflective cover, and an optical diaphragm group which are sequentially arranged from bottom to top. The optical diaphragm group includes at least one diffusion diaphragm, and a plurality of microlens structures are arranged on a light emission side and/or a light incidence side of the diffusion diaphragm to form a microlens structure surface. In the backlight module provided by the disclosure, light is subjected to multiple reflections between the reflective cover and the diffusion diaphragm, thus improving the light emitting uniformity along the diffusion diaphragm.
