DIFFUSION REFLECTIVE SHEET FOR LED LIGHT

摘要

To improve lens mura generated by brightness difference due to the reduction of light distance according to the slimming of BLU (back light unit) for display, the present invention relates to a diffusion reflective sheet. Diffusion is increased by uniformly spraying spherical particles on a side of a reflective sheet which is arranged on the same line as an LED light source, thereby reducing the amount of light reflected from a slope. The diffusion reflective sheet for an LED light source has spherical particles of a size of 0.1 to 500μm which are coated on a side of a refractive sheet. Because the diffusion reflective sheet for an LED light source has a side which is coated with spherical organic particles by a specific resin binder, a diffusion sheet provides superior diffusion to a side of a reflective plate in an LED direct type backlight unit structure and prevents the lens mura of an LED point light source, and solves an existing problem.
