반도체공정공학 OLED (Organic Light-Emitting Diodes) 설계 [반도체공정공학] OLED (Organic Light-Emitting Diodes) 설계.pptx 목차 1.Introduction 2.Fabrication 3.Conclusion 본문 organic light emitting diode(OLED) LEDs emissive electroluminescent layer is composed of a film of organic compounds. This layer of organic semi-conductor material is formed between two electrodes, where at least one of the electrodes is transparent. OLED can be used in many display devices. Active matrix OLED has an integrated electronic backplane made from thin film transistors(TFTs) Each pixel addressed independently A defective pixel produces only a dark defect, which is considered to be much less objectionable than a bright point defect(such as in LCD panels), or a line defect Easy and cheap to build Limited to small sizes Power consump-tion is not good as AMOLED More expensive, more difficult to create Can be used for larger displays Power efficiency is good ITO IZO Others on developing -CNT film -ZnO:Al Why ITO? What another materials can be used? How about flexible transparent plastic? Yes, it’s flexible display!!
