Effect of Height and Radius(h/r)Ratio of Micro Lens Array Pattern on the Light Extraction of OLEDs
In this paper we discussed the effect of micro lens array(MLA) pattern fabricated on the glass substrate of organic light emitting diode(OLED) for improvement of light extraction efficiency. The MLA patterns were formed by combination of photolithography and thermal reflow method and its effect on light extraction efficiency form OLED device was examined.
