The invention discloses a backlight module with a wedge-shaped light guide strip. The backlight module comprises a bracket, a light source, reflective paper, the wedge-shaped light guide strip, an reflection sliver layer, a diffusion plate and a cavity; one side of the light source is attached to the inner side of the side wall of the bracket; the wedge-shaped light guide strip is attached to theother side of the light source, the lower surface of the wedge-shaped light guide strip is in contact with the bottom of the bracket, and the upper surface of the wedge-shaped light guide strip is provided with the reflection sliver layer; the reflective paper is placed at the inner side of the bottom of the bracket and is in contact with the edge of the bottom of the wedge-shaped light guide strip; the lower surface and wedge-shaped surface of the wedge-shaped light guide strip are provided with dots arrayed in a matrix shape respectively; the diffusion plate is placed on the wedge-shaped light guide strip; the wedge-shaped cavity is formed by the reflective paper, the wedge-shaped light guide strip and the diffusion plate. The backlight module with the wedge-shaped light guide strip hasthe functions of lightweight light guide plates.
Description
technical field [0001] The invention relates to a backlight module with a wedge-shaped light guide strip, in particular to a backlight module with a wedge-shaped light guide strip for a lightweight light guide plate. Background technique [0002] The light guide plate is to use optical grade acrylic / PC board, and then use high reflectivity and non-absorbing high-tech materials to print light guide points on the bottom surface of the optical grade acrylic board with UV screen printing technology . The optical-grade acrylic plate is used to absorb the light emitted from the lamp to stay on the surface of the optical-grade acrylic plate. When the light hits each light guide point, the reflected light will spread to all angles, and then destroy the reflection condition and be emitted from the front of the light guide plate. Through light guide points of various densities and sizes, the light guide plate can be made to emit light evenly. [0003] In recent years, in the display...
