INTEGRATED BACKLIT FRONTLIGHT FOR REFLECTIVE DISPLAY ELEMENTS |
摘要 |
This disclosure provides systems, methods and apparatus, including reflective display elements that are illuminated using a light source that is situated behind the pixel elements. In one aspect, a back light guide is disposed behind the pixel elements and is configured to inject light through light-injection apertures between reflective pixel elements. The light travels through the light-injection apertures and into a front light guide. The front light guide comprises light turning features configured to turn the light propagating through the light-injection apertures so that the light is redirected onto the reflective pixel elements, thereby illuminating the reflective pixel elements. |
