Optimization of Micro Lens Array(MLA) Pattern for the Improvement of Light Extraction Efficiency in OLED Devices

摘要

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 effect of MLA on light extraction efficiency from OLED was examined by the fabrication of various MLA on the devices.
