Abstract

An antistatic reflective film of a Mini-LED backlight module comprises a core layer with microbubbles, a light diffusion upper layer is compounded on one side of the core layer, an antistatic lower layer is compounded on the other side of the core layer, and the light diffusion upper layer is composed of a coupling agent modified inorganic filler, light diffusion particles, an antistatic agent and PET particles; and the antistatic lower layer is prepared from the coupling agent modified inorganic filler, the antistatic agent and the PET particles. The light diffusion upper layer containing the coupling agent modified inorganic filler, the electrostatic lower layer and the core layer are matched to form the reflective film with improved antistatic performance.

Description

technical field [0001] The invention relates to a reflection film of a Mini-LED backlight module. Background technique [0002] The Mini-LED backlight module uses Mini-LED as the backlight to reduce the size of the direct-type LED backlight module, and turns dozens of LED lamp beads into thousands, tens of thousands, or even more lights. beads. Compared with traditional backlights, Mini-LED has more advantages and is suitable for high-end LCD solutions. [0003] Mini-LED backlight modules currently on the market are mainly composed of blue-light Mini-LEDs, reflective films, diffusion films, quantum dot films, and uniform light lenses. Due to the small size of light-emitting LEDs, static shocks are likely to occur during the preparation and assembly of displays. If it is worn out, the lamp beads will be deactivated and affect the product quality. Therefore, higher requirements are put forward for the antistatic performance of the reflective film.
