Thin backlight module and manufacturing method thereof

A manufacturing method of a thin backlight module, comprising steps as follows:

• providing a drive substrate;
• arranging a plurality of light emitting sources on the drive substrate;
• producing a plurality of reflecting layers on the drive substrate, wherein each of the reflecting layers is arranged between each two adjacent ones of the light emitting sources;
• providing a diffusing layer on the fluorescence layer;
• providing a top coat layer on the diffusing layer;
• forming a fluorescence layer on the light emitting sources, and hot-pressing a plurality of surface micro-structures on a surface of the fluorescence layer, wherein the surface micro-structures are disposed in a one-to-one correspondence with the light emitting sources, a center of each surface micro-structure is arranged corresponding to a center of a corresponding one of the light emitting sources, and an inclined surface or a curved surface is defined between the center of each surface micro-structure and the surface of the fluorescence layer;
• and
• forming a particle micro-structure on each of the surface micro-structures, wherein each of the particle micro-structures contains particles of a concentration, each particle micro-structure and each surface micro-structure together form a guiding layer for dispersing light from a corresponding one of the light emitting sources, the guiding layer is arranged between the fluorescence layer and the diffusing layer, and the light emitting sources are arranged in the fluorescence layer and arranged corresponding to the guiding layer.
