Abstract
Two different techniques are used in this research platform, were the first attempt is using nano semiconductor-condensed (CdSe) Quantum dot optical filter which works as highly efficient nano-crystals and placed between the blue (444nm) LED light source and liquid crystal module (LCM) to extend the LCD display NTSC color volume more than 103%. Apart from the high costly QD filter, low-cost KSF (Potassium Silicofluoride-K2SiF6) compound material coated on one set blue LED chip and optically placed between reflector film and LCM, act as a main light source which also emits highly efficient narrow-band pure white light to resonate the liquid crystal module (LCM) and extend NTSC color gamut percentage of LCD display panel more than 87%. Mentioned methods are not only improving the color volume but have also improved the overall picture quality (PQ) with low power consumption status of a display panel. These techniques & optical measurements are verified for both edge and direct type display BLU structure within HD & FHD resolution.
