Optical sheet and method of assembling liquid crystal display module using the same
View Patent ↗The present invention relates to an optical sheet and a method of assembling a liquid crystal display module that is capable of preventing an inflow of impurities on a backlight unit, thereby minimizing screen staining caused by the impurities. An optical sheet installed between a liquid crystal display panel and a light guide member according to the present invention includes a transparent peeling sheet adhered to the front surface of the optical sheet facing the liquid crystal display panel; and a semitransparent peeling sheet stuck to the rear surface of the optical sheet facing the light guide member.
1. An optical sheet comprising:
a diffusion sheet;
a lower prism sheet on the diffusion sheet;
an upper prism sheet on the lower prism sheet;
a transparent peeling sheet adhered to a front surface of the upper prism sheet; and
a semitransparent peeling sheet adhered to a rear surface of the diffusion sheet.
2. The optical sheet according to claim 1 , wherein the material of the transparent peeling sheet is Polyethylene Terephthalate PET.
3. The optical sheet according to claim 1 , wherein the material of the semitransparent peeling sheet is Polyethylene.
