Abstract

Abstract : In this paper, we developed high color gamut OLED microdisplay. To minimize the crosstalk, a single stack white OLED structure with RGB main peaks was adopted, and RGB color filters were directly patterned on the OLED. In addition, we designed the optical crosstalk prediction model, which could predict the light loss according to the thickness of the passivation layer. As a result, we achieved high color gamut of 125.0% at sRGB, which demonstrated the high color gamut OLED microdisplay.
