- To implement primary colors in high-resolution organic light-emitting diode (OLED) microdisplays, color filters or cavity structures are applied to white OLEDs (WOLEDs). In terms of the high luminance and high color gamut required by microdisplays, two methods were experimentally compared in this study. In addition, a method for applying a color filter to WOLEDs with high-order cavity structures is proposed. The luminance of the proposed structure is lower than that of the cavity-only structure, but is similar to that obtained by applying a color filter to normal WOLEDs. Although previous methods do not satisfy the BT.2020 standard, the proposed structure achieves 90.8% of the BT.2020 standard.
