LCD backlight device having light guide plate with optical scattering dots

摘要

The following invention relates to an improved LCD Backlight, particularly to an improved arrangement of the optical scattering dots within the light guiding plate.;The light guiding plate comprises a lower surface which is formed with a plurality of optical scattering dots, which scatter and reflect the light beams to convert the light beams into a uniform surface light source, characterised wherein the surface area of each optical dot decreases as a function of its distance from at least one of the three edges comprising the LED lights.
