LIGHT GUIDE

A light guide having opposing first and second major surfaces where the first major surface includes a plurality of extended features and a plurality of discrete features is described. The light guidehas a viewable area having a length at least 100 times a thickness of the light guide. The extended features extend in a first in-plane direction across at least 90 percent of the length L of the viewable area. The discrete features are spaced apart along the length and width of the viewable area. The discrete features may be disposed in spaces between the extended features. The discrete featuresmay have faces extending between and connecting adjacent extended features. 本发明描述了一种光导，其具有相反的第一主表面和第二主表面，其中第一主表面包括多个延伸特征和多个离散特征。该光导具有可视区，该可视区的长度是光导的厚度的至少100倍。多个延伸特征横跨可视区的长度L的至少90％在第一平面内方向上延伸。多个离散特征沿可视区的长度和宽度间隔开。多个离散特征可设置在多个延伸特征之间的空间中。多个离散特征可具有在相邻的延伸特征之间延伸并将相邻的延伸特征连接的面。
