Abstract

The invention discloses a light guide board and a manufacturing method thereof, a backlight source module as well as a display device, which are designed for a lot of defects existing in the manufacturing method of the conventional light guide board. The manufacturing method of the light guide board provided by the invention comprises the following steps of: placing nanometer magnetic conduction particles on a substrate; arranging the substrate placed with the nanometer magnetic conduction particles in a controllable magnetic field, so that the nanometer magnetic conduction particles are in magnetic line distribution on the substrate; selecting a set area on the substrate; and placing a light passing board above the set area, and keeping the nanometer magnetic conduction particles in the set area in a magnetic line distribution pattern and fixing the nanometer magnetic conduction particles on the light passing board. The manufacturing method provided by the invention can conveniently adjust the distribution of scattered lattice points of the light guide board; and no pollution exists in a manufacturing process, and the process cost is low. Furthermore, the light guide board provided by the invention uses the nanometer magnetic conduction particles as a lattice point material, thereby enhancing scatter and reflection of light, and improving the emergency efficiency of the light guide board.

Description

technical field [0001] The present invention relates to the technical field of liquid crystal display, and in particular to a light guide plate with scattering dots distributed in magnetic force lines and a manufacturing method thereof, as well as a backlight source module and a display device including the light guide plate. Background technique [0002] In the backlight module of the LCD (Liquid Crystal Display) industry, the light guide plate is one of the key components. At present, the manufacturing method of the light guide plate mostly adopts the printing method or the laser etching method. However, these methods have certain defects, which are as follows: [0003] (1) The printing method and the laser etching method require a mask. A slight change in the design of the light guide plate requires a replacement of the mask. However, the process of changing the template for making the mask is cumbersome and not reproducible. The cost will increase accordingly. [0004...
