P‐5.10: Study on the Reflection of COE

COE (Color filteron Encapsulation) is a new technology usedCF (color filter) and BM (black matrix) structures instead ofthe polarizer. Itis found that COE shows the greatadvantages in reducingpower consumption, due to the high transmittance of CF, However, because ofthe high transmittance of CF and the pattern structuresof OLED film, the disadvantage of COE technologyishighreflection. Based on the thin film optical theory, the paper studies the film factors of OLED and summarizes the main factors that affect Reflection.
