Backlight module

A backlight module, comprising:

• a light-guiding plate, the light-guiding plate having a light output surface, a back surface opposite to the light output surface, and a light input side surface between the light output surface and the back surface, the back surface comprising a central portion and a third fringe portion, the back surface having a second edge and a third edge adjacent to the second edge, the third fringe portion extending along the third edge, the light input side surface being adjacent to the second edge, the central portion comprises an original area and a side adjustment area, the side adjustment area being located between the original area and the third fringe portion and being adjacent to the original area and the third fringe portion;
• a plurality of reflection spots, the reflection spots being distributed over the central portion and the third fringe portion, a distribution density of the reflection spots on the third fringe portion gradually decreasing in a direction from the central portion toward the third edge, a distribution density of the reflection spots on the side adjustment area being less than a distribution density of the reflection spots on the original area;
• and
• a light source, the light source being disposed toward the light input side surface.

• a plurality of reflection spots, the reflection spots being distributed over the central portion, the first fringe portion, and the third fringe portion, a distribution density of the reflection spots on the first fringe portion gradually decreasing in a direction from the central portion toward the first edge, a distribution density of the reflection spots on the third fringe portion gradually decreasing in a direction from the central portion toward the third edge, a variation rate of a distribution density of the reflection spots on the upper adjustment area being greater than a variation rate of a distribution density of the reflection spots on the original area;
• and
• a light source, the light source being disposed toward the light input side surface.
