Zusammenfassung:	The invention relates to a structure and a method thereof for luminenscence homogenization of a backlight module. The structure comprises at least one light source and a light guide plate, wherein the light guide plate is provided with a light incident surface; the light source is arranged on the light incident surface; the light guide plate is provided with a plurality of optical micro-structural units comprising a plurality of secondary optical micro-structural units; and the distribution density of the optical microstructural units on the light guide plate is increased along with the increasing distance to the light source in an axis X direction and an axis Y direction, and the distribution density of the secondary optical micro-structural units on the optical micro-structural units is also increased along with the increasing distance to the light source in the axis X direction and the axis Y direction. The invention has the advantages of effectively solving the problem of the brightening visual effect gen
