“…In this case, the trapped waveguide mode can also be extracted via scattering resulting in much higher OCE, because there is nearly no index barrier between the substrate and the ITO/organic layers. On the other hand, there have been many studies on the effect of lenses on the OCE [19][20][21]. Application of a hemi-spherical lens on the substrate was found to increase the OCE by 1.6~3.0 depending on the refractive index and lens parameters [19].…”

“…Using a single lens on OLEDs, however, increases the thickness of the OLED device. In this context, microlens-based optical structures are preferred for practical applications [20][21]. Compared to the microlenses of which the cross-section is circular on the substrate, the fill factor of pillow lenses, which is 100%, is much higher.…”

“…51 Some of the trapped light is reabsorbed or emitted through edge emission. There have been many efforts to extract the trapped light by texturing the surface on the light emitting side, 52 putting microlens arrays on the other side, 51,[53][54][55] or both. 56 Both schemes are breaking total internal refractions, in the high index mode by texturing, or in the glass mode with the microlens array.…”

“…56 Both schemes are breaking total internal refractions, in the high index mode by texturing, or in the glass mode with the microlens array. They can be regular periodic structures 51,[53][54][55][56] or randomly roughened surfaces. 52 In periodic structures, light is extracted in the surface plasmon mode or by refracting the ray as classical optics depending on the size, periodicity, and refractive index of the textured surface.…”
