Xinruida obtained a patent for a MiniLED chip backlight module that emits uniform light

The patent abstract shows that the present invention discloses a MiniLED chip backlight module with uniform light emission, including a PCB board, a MiniLED chip, a microlens, a reflective paper, a diffusion sheet, a diffusion plate, a quantum dot film, a prism sheet, and a liquid crystal screen; a MiniLED chip is provided on the surface of the PCB board , Microlens, the microlens surrounds the outside of the MiniLED chip; the microlens is annular on the surface of the PCB board, and the central axis of the microlens coincides with the central axis of the MiniLED chip; the microlens is composed of multiple concentric wedge-shaped rings, and the height of the multiple concentric wedge-shaped rings gradually increases from the inside to the outside. The invention has the characteristics of improving the energy efficiency and brightness of the backlight module, improving the light mixing path, reducing the light mixing height OD, thinning the backlight module, reducing process steps, reducing production costs, simultaneously increasing production capacity, and improving the light uniformity of the backlight module.
