A portion of the transmitted light then reflects off the back surface.

部份穿透过去的光 又被後面表面反射回来。

This property would make them suitable both for displays that rely on reflected light (so-called electronic paper) and the older, backlit sort that rely on transmitted light.

这一性能将使其适合于反射光显示（所谓电子纸）和早期的依赖透射光的背光显示。
