Abstract

The invention discloses a wear-resistant high-transmittance reflecting piece, and the reflecting piece comprises a PET base material. The surface of the PET base material is provided with a pluralityof high-transmittance particles and PET particles. The size of the PET particles is greater than the size of the high-transmittance particles, and the number of high-transmittance particles is greaterthan the number of PET particles. The reflecting piece can effectively solve a problem that the high-transmittance particles make direct contact with a light guide plate, improve the reflectivity ofa light source, improve the transmittance of coating particles, improve the reflectivity, and prevent the attaching of the reflecting piece and the light guide plate from causing a halation phenomenon.

Description

technical field [0001] The invention relates to the field of optics, in particular to a wear-resistant high-transmittance reflective sheet. Background technique [0002] The reflection sheet reflects the unscattered light source and then enters the light transmission area. The reflection method is specular reflection to improve the utilization rate of light. At present, in order to form particles with irregularities on the surface to prevent adhesion to the light guide plate to ensure a gap, by coating PET soft particles on the PET base material, the effect of inhibiting the adhesion to the light guide plate and the inhibition of the light guide plate can be achieved at the same time. damage effect. [0003] The disadvantage of the prior art is that the light reflected by the reflective layer will be partly blocked by the PET particles, resulting in low reflectivity of the entire reflective sheet. Contents of the invention [0004] The purpose of the present invention ...
