  • The transmittance of bare glass was enhanced up to about 20% by coating it with a PMMA (Poly Methyl Meta Acrylate) film mixed with silica gel. This lowrefractive- index film greatly reduces total reflection inevitable for bare glass, and thus will be useful for increasing the coupling-out efficiency of OLED.
