Abstract

The invention relates to the technical field of circuit boards, in particular to a mini LED lamp panel which comprises a brightness enhancement film, a polycarbonate layer and an aluminum substrate; an organic nanometer microbead light diffusion agent is mixed in the polycarbonate layer, M-shaped protrusions are arranged at the positions, where lamp beads are located, of the polycarbonate layer, the brightness enhancement film is arranged on the polycarbonate layer, and a refractive film with a prism structure is arranged between the lamp bead and lamp bead. The diffusion glue layer mixed withdiffusion particles is adopted, and the refraction film with the prism structure is arranged between the adjacent lamp beads, so that the light radiation area is larger, and a more uniform display effect can be achieved.

Description

technical field [0001] The invention belongs to the technical field of LED lamp panels, in particular to a mini LED lamp panel. Background technique [0002] In recent years, as the manufacturing technology of LED lamps has become increasingly mature, and LED has the advantages of low power consumption, low heat generation, long service life, fast start-up speed, rich colors and good brightness, it can save a lot of power consumption for lighting fixtures. Therefore, as the concept of environmental protection is increasingly valued today, LEDs have gradually replaced traditional lamps and become the mainstream of the future market. [0003] Due to the limitation of the light-emitting angle of the mini LED, the light energy emitted by it is mainly concentrated in a certain range in the vertical direction, resulting in uneven brightness and darkness of the backlight screen. Contents of the invention [0004] In order to solve the above problems, the present invention provid...
