Large-scale active luminance film with enhanced polarization made of aligned quantum-rod-containing polymeric nanofibers for highly efficient and wide color gamut LCD displays
摘要
Abstract
CdSe/CdS quantum rods(QRs)with polarized light emission have great potential in the next generation liquid crystal displays(LCD)backlight.Aligning these QRs in large scale is the key for practical applications.In this paper,we report a large scale film made of aligned QRs in PMMA fi-bers.Making use of a new tributylphosphine(TBP)-assisted synthetic method,we firstly synthesized uniform CdSe/CdS QRs with high absolute quantum yield(QY)of 60%,narrow full width at half maximum(FWHM)of 25 nm and large Stokes shift of 182 nm.Then,these oil phase CdSe/CdS QRs (maintaining the high absolute QY)dissolved in the mixed solution of chloroform, dimethylformamide(DMF)and polymethyl methacrylate(PMMA)were used to electrospin aligned QR-containing PMMA nanofibers.Collecting these fibers by a roller,we were able to make large-scale active luminance film with enhanced polarization with these PMMA nanofibers aligned.For a 5 cm2 size film,the polarization was measured to be 0.45.The film was further inserted into a mobile LCD for test and the brightness of LCD was enhanced by 18.4% with the film.Our results indicate that our aligned film is a very promising backlight solution for highly efficient and wide color gamut LCD dis-plays.关键词
