We present flexible transmissive structural color filters with high-color-purity based on a higher-order resonance suppression by inserting an ultrathin absorbing layer in the middle of a cavity. A ...
Color filters are widely used over various areas, such as liquid crystal displays (LCDs), white organic light-emitting diode displays (WOLEDs), image sensors, and anti-counterfeiting devices 1,2,3,4.
A new class of laser emission technology enabling ultra-high color purity and continuous spectral tunability at low voltage has been developed, marking a significant advance beyond conventional ...
