Blue LED-pumped green and red quantum dots generate highly saturated colors while keeping a higher efficiency than white LEDs.Such a quantum-dot lit LCD exhibits several outstanding features: extremely wide color gamut(142%of NTSC),matched spectra with color filters,easy to obtain perfect white point,excellent angular color uniformity,and negligible color shift.Meanwhile,polymer-stabilized blue-phase liquid crystal exhibits submillisecond-to-microsecond response time,which not only suppresses image blurs but also enables field sequential color displays without color breakup.The latter triples optical efficiency and resolution density.The integration of quantum-dot backlight with blue phase liquid crystal leads to an exciting new era for LCDs.
