Display technology has not only presented information traditionally, but also multifunctional capability, flexibility, lightness and slimness design are desired attributes for being adopted by artificial intelligence (AI) to interact with consumers. In this regard, ferroelectric poly(vinylidenefluoride-co-trifluoroethylene) (PVDF-TrFE) is of great interest as potentially applicable for display power saving material with having mechanical stability, transparency, and electrically controllable polarization. Here, we report the experimental study of a luminescent light harvesting property of CdSe QD embedded P(VDF-TrFE) nanocomposite, whereas concentration of QD is not as much high as to interfere presenting information in visual. In agreement with theoretical calculation, the converted power from luminescent light guided to c-Si solar cell is enhanced by 42% based on the quantum-confined Stark effect (QCSE) owing to ferroelectric polarization of P(VDF-TrFE). The resulting nanocomposite shows enhanced mechanical sensitivity (~40%) by aligned dipole moment of P(VDF-TrFE) upon mechanical contact. This nanocomposite material may potentially be applicable as multimodal display element not only enable to power itself but also detect given mechanical touch.
