ABSTRACT:
A full-color electroluminescent display with improved efficiency and increased color gamut that includes substantially complementary yellow and blue light-emitting elements, the chromaticity coordinates of which define the endpoints of a line that intersects a Planckian locus within the interval 0.175<=u′<=0.225 within the Commission Internationale de l'Eclairage (CIE) 1976 u′v′ chromaticity space. Also included in the display is a green light-emitting element of spectrum having a dominant wavelength between 500 nm and 540 nm and a full width, half maximum spectral bandwidth of 50 nm or less; and a red light-emitting element.
