Description
本发明属于光电材料领域，具体涉及一种集光高透过率、高雾度及高韧性于一体的光扩散板。
扩散板目前已广泛应用在液晶显示、LED照明以及成像等系统中，使入射光充分散射，实现更柔和、均匀的照射效果。扩散板是在生产实心板的时候，在原料中添加扩散剂而成的。扩散剂能均匀分布在板材内，使光线经过板材时，碰到扩散剂颗粒时发生折射，反射，散射的效果，从而使光线可以均匀的透过板材但又不会露出光源，达到从点光源向面光源的变化。适用于直下式LED电视机背光模组、手机模组、LED照明，具有高辉度、高扩散性，提高背光源的发光分布均匀的扩散效果。
对于扩散板的研究较多，CN200680055637和专利CN101684922A公开了一种光扩散板的制造方法，专利公开了无机扩散剂，如碳酸钙、二氧化硅、硅氧烷、硫化锌、氧化钛、磷酸钛、钛酸镁、云母、玻璃填料、硫酸钡、粘土、滑石；硅橡胶类弹性体、聚甲基硅氧烷烷等和有机物如丙烯酸、苯乙烯、聚酯型、聚烯烃型、脲烷型、尼龙型、甲基丙烯酸苯乙烯型、氟型、降冰板烯型等作为扩散剂的方案。专利中提到的无机粒子如二氧化硅，已经是市场上一种常用的光扩散剂，这些无机粒子加入到树脂中虽然可以增加树脂的雾度，但是会大幅度降低透光率，一般地，加入这种无机粒子的扩散板的透光率(1.2mm聚碳酸酯PC)不会大于70％。专利中提到的有机类光扩散剂可以降低光透过扩散板时的损失，但是也不能彻底避免光线的损失，在雾度合适的情况下，添加有机光扩散剂获得的光扩散板的透光率一般不大于80％(1.2mm聚碳酸酯PC)。
随着TV市场人们的需求，现在的背光模组的厚度越来越薄，光源利用率要求越来越高，在不影响辉度的同时对扩散板雾度、韧性的要求也越来越高；目前国内外市场上生产的扩散板越来越无法满足终端市场需求。
因此，进一步增加光源的透过率、减少光源损耗、改善背光模组的出光均匀度，提高整个模组的亮度，在光扩散板上实现集高辉度、高雾度及高韧性等功能于一体成为目前扩散板行业的研究重点。
