摘要：
The combination of white organic light-emitting devices (OLED) and color filters is one of the most promising technologies for full-color OLED displays. Yet, the transmission spectra of most available color filters are broad and poorly match the electroluminescence spectra of white OLEDs, yielding less saturated filtered colors and small color gamut for displays. In this work, we report that by employing the microcavity structure only in green pixels for such OLED display technology, one can simultaneously achieve simplification the manufacturing process, enhancement of color performances, and enhancement in efficiencies for OLED displays.
