This technology combines optical, materials, designElectrical technology to develop a harvesting power supply system with the e- paper driver function. The technology of the Dye-Sensitized Solar Cell (DSSC) will transform indoor light into electrical energy. The Solar Cell energy from harvesting IC is stored in the Lithium battery. Provide 5V power supply with lithium battery by using boost circuit. The 5V power supply makes the e- paper driver function, with the replacement of the e-paper image content. The system does not need to use the Utility Power,e-paper display technology can be applied to product price tag of the retail store, posters, electronic billboards, e-book, etc.

Dye-Sensitized Solar Cell can be used indoors more efficiently. The Solar Cell energy from harvesting IC is stored in the Lithium battery,provides 5V power supply with lithium battery by using boost circuit. The 5V power supply makes the e-paper driver circuit function. The system is combination of research technology in various kinds of fields in Hierarchical Green-Energy Materials Research Center Research. It is practical in the industryshows as the realization of green energy achievements. E-Paper is a display technology. The image displayed can still be clearly visible in direct sunlight. E- Paper display technology can be applied to retail store price target signs, posters, electronic billboards, e-book, etc.
