2 OLED 2 lapis : Conducting layer dan Emissive layer. OLED 3 lapis : Electron Transport Layer, Emissive Layer, Hole Transport Layer. OLED Semikonduktor padat berukuran 100-500 nm OLED dapat terdiri dari 2-3 lapisan senyawa organik. bagian OLED : substrat, anoda, lapisan senyawa organik, serta katoda.

3  Mengemisikan cahaya  Kaya warna (termasuk hitam)  View angle lebih luas  Konsumsi energi lebih rendah  Biaya produksi OLED lebih rendah dibandingkan produksi LCD  Susbstrat fleksibel
