Backlight illumination structure based on double-sided light-dimming light guide plate and manufacturing method of backlight illumination structure

The invention relates to a backlight illumination structure based on a double-sided light-dimming light guide plate and a manufacturing method of backlight illumination structure. The illumination structure comprises a side-entry type light source, a light guide plate, a base plate light-guiding layer, a quantum dot colored film layer and a spot light micro-structure, wherein the side-entry type light source, the light guide plate, the base plate light-guiding layer, the quantum dot colored film layer and the spot light micro-structure are sequentially arranged; a colored light filter in a liquid crystal panel is moved into backlight through the backlight structure, and is combined with a light-dimming scattering micro-structure of a scattering layer so as to perform light dimming; due tolight extraction of the light-guiding layer and light modulation of the micro-structure, the phenomenon that the structure has uniform light output is ensured simultaneously, optical film plates are integrated, so that the si
