application of OLED 143. 6 OLED 타일 154. 참고 문헌 161. Organic Light Emitting device (or diode)1.1 (AM)OLED - 소개최근 국내외적으로 OLED 에 대한 관심이 점차 높아져 가고 있다. OLED, 즉 유기 발광 다이오드는 빛을 발산하는 다이오드 (LED) 가운데 layer 가 organic compound 로 이루어진 film 으로 구성된 것을 말한다. 구조적으로 보면 유리 기판 상에 3원색의 유기 소자가 matrix 형태로 형성된 flat pannel display인데 기판은 organic compound 들이 증착되기 용이한 polymer substance 를 포함하

of LCD) and ultra-thin screen(1/3 of LCD, below 2mm thickness is possible)3. FlexibilityIt can be applicable to the curved shape part.4. Eco-friendlyIt is eco-friendly since it doesnt contain the toxic substances such as Hg.5. Wide viewing angleViewing angle is the range of oblique angle which we can see the normal screen. Unlike LCD, the image quality doesnt change though it is seen from just beside.6. Fast response speedIf we play moving images, the quality of the screen is determined by the response speed. OLED shows natural screen of the moving images which have the similar leve
