Optical efficiency enhancement in white organic light-emitting diode display with high color gamut using patterned quantum dot film and long pass filter

“…14) It has a wavelength-dependent characteristic that transmits some light and reflects the other light selectively by choosing appropriate materials and thicknesses for its dielectric layers. 15,16) Many researchers have designed LPF structures and applied them to many optoelectronic devices such as surface-emitting lasers to emphasize certain wavelengths of light, [17][18][19] solar cells for selective transmittance of certain wavelengths of light, 20) and white lightemitting diodes (LEDs) to improve the luminous efficiency and light quality. [21][22][23][24] However, the LPF has not been applied to the display field until now.…”

Super color purity green organic light-emitting diodes with ZrO2/zircone nanolaminates as a distributed Bragg reflector deposited by atomic layer deposition

“…Facing these applications, a narrow spectrum width is very important for getting high color purity [4,5]. Microcavity OLEDs with semi-transparent distributed Bragg reflectors (DBR) have a selected emission wavelength and a narrow spectrum width because of the coupling of the active region with the Fabry-Perot cavity mode [6,7]. These reflectors demonstrate selective reflectivity in a specific wavelength range, which creates constructive interference and efficiently suppresses other modes, thereby resulting in a high reflectance over a certain wavelength range depending on the difference in refractive indices between the constituting layers.…”
