Patent ID: 8870432

Claim:
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.
