Sheetless backlight module, a light guide plate for the sheetless backlight and manufacturing method thereof

摘要

A sheetless backlight module and a light guide plate thereof are provided. The light guide plate includes a body and a plurality of light scattering units. The body has a bottom and a plurality of microstructures formed on the bottom and recessed in the body from the bottom. The pluralities of light scattering units are disposed in a plurality of spaces formed due to the plurality of microstructures recessed in the body. A manufacturing method of the light guide plate mentioned above includes forming the plurality of microstructures on the bottom of the body; preparing a fluid solution containing at least a diffusive reflective material; distributing the fluid solution on the bottom; driving the fluid solution to flow into the microstructures; removing the part of the fluid solution outside the microstructures; and solidifying the fluid solution to form the plurality of light scattering units.

主权项

1. A light guide plate for a sheetless backlight module, comprising:
a body, having: a light-exiting face; a bottom located opposite to the light-exiting face; and a light-entering end located on one side of the light-exiting face and the bottom and connected to the light-exiting face and the bottom; a plurality of microstructures formed on the bottom of the body and recessed in the body from the bottom; and a plurality of light-scattering units disposed in a plurality of spaces formed due to the plurality of microstructures recessed in the body, wherein the body has a value of bidirection scattering distribution function determined by emitting a light beam with a specific angle of incidence to the body, the light-scattering unit has a value of bidirection scattering distribution function determined by emitting a light beam with a specific angle of incidence to the light-scattering unit; the value of bidirection scattering distribution function of the light-scattering units is greater than the value of bidirection scattering distribution function of the body.
