摘要:
This disclosure provides systems, methods and apparatus related to an illumination system for a display device. In one aspect, the illumination system includes a light guide (902) having a view region (914), which directly overlies display elements of a display, and a ledge region (916) between the view region and a light source (904) that injects light into the light guide. The ledge region is coated with an at least partially non-transmissive layer (922). The layer can be at least partially absorptive and/or at least partially reflective. In some implementations, the layer can include microstructures configured to turn steep-angle light such that it is redirected across the light guide at a shallower angle. In some implementations, the boundary between the ledge region and the view region of the light guide can have a nonlinear shape.
摘要(中):
本公开提供了与显示装置的照明系统相关的系统,方法和装置。 在一个方面,照明系统包括具有视图区域(914)的光导(902),其直接覆盖显示器的显示元件,以及在视野区域和光源(904)之间的凸缘区域(916),其中 将光线注入光导。 凸缘区域涂覆有至少部分不透光层(922)。 该层可以是至少部分吸收的和/或至少部分反射的。 在一些实施方案中,该层可以包括构造成转动陡峭角度的光的微结构,使得其以更浅的角度被重定向穿过光导。 在一些实施方案中,凸缘区域和导光体的视野区域之间的边界可以具有非线性形状。
