Backlight module
First Claim
1. A backlight module, comprising:
- a substrate having an opening on top;
a first reflective plate, disposed on a bottom surface of the substrate;
a plurality of light guide plates, disposed on the first reflective plate with intervals in between;
backlight source components comprising heat sink shelves, and point light sources that are fixed on the heat sink shelves and inserted in the interval between two neighboring light guide plates; and
a plurality of optical films disposed on the opening of the substrate,wherein walls of the substrate comprise a first part that is neighboring to the bottom surface of the substrate, and a second part that extends from the first part and folds outward as it goes upward;
a second reflective plate is adhered to the internal surface of both the first part and the second part.

Abstract
A backlight module includes a substrate having an opening on top, a first reflective plate disposed on a bottom surface of the substrate, light guide plates disposed on the first reflective plate with intervals in between, backlight source components, and a plurality of optical films disposed on the opening of the substrate. The backlight source components comprise heat sink shelves, and point light sources that are fixed on the heat sink shelves and inserted in the interval between two neighboring light guide plates. The present invention effectively reduces the width and thickness of the backlight module, and is instrumental for a narrow-frame and ultra-thin design, effectively reduce production cost. Meanwhile, the arrangement ensures good backlight uniformity, and is instrumental in reducing the distance needed for light mixing. Additionally, the defect of dark band appearing around the backlight module of traditional backlight modules can be effectively eliminated.
