목차 1. Introduction 2. Principle of F.D 3. Advantages & Disadvantages 4. Current Status 5. Marketability & Prospects 6. Conclusion 7. Reference 본문 LCD Panel can't emit light by itself. So, We need backlight unit to emit light. TFT Array - Controls quantity of traveling light Liquid crystal (core of substance) Controls the brightness of light Color Filter Array Controls the color of light Back light Emits the light OLED emits light passing current through organic materials. TFT Array Controls the current . Anode & Cathode Performs a role like anode & cathode of battery. ENCAP(Encapsulation Glass) Blocks air and moisture to prevent spoiling. Uses external light except Backlight or spontaneous light. Color filter inside glass substrate controls the color of light E-ink Light penetrates through (+) particle inside E-ink easily. (-) particle absorbs light inside E-ink easily. Advantages & Disadvantages Advantages 1. Good fabrication - Rugged , bending , rollable 2. Thin thickness 3. Light weight 4. Strong for impact 5. Possibility of continuous processing Disadvantages 1. Battery 2. Limitation of color expression 3. Short life time 4. Weak thermal resistance Limitation of Commercialization Life time PC monitor's lifetime is 100,000 hours. But, lifetime of E-paper is only 10000 ~ 20000 hours . Ability to color of E-paper Limitation of color materialization. Processes Hard to materialize as printing method of roll-to-roll Increase in lifetime Prevention from penetration of water and moisture. Formation of color layer having conductivity in the display. Improvement of Process efficiency through roll-to-roll sputter. 참고문헌 플렉서블 디스플레이 기술 최종선, 도이미, 홍익대학교, ETRI http://www.displaybank.com : 디스플레이 기술 현황 조사 Flexible OLED Display : 기술 개발 현황 및 기술적 이슈 모연곤(삼성 SDI) 디스플레이용 플라스틱 기판의 전망 김기헌, 송윤호, 전자통신동향분석 제 23권 제 5 호 전자종이(E-Paper)의 기술개발동향 반병섭, 김재훈(한양대 정보통신공학부) The Korean Information Display Society EIC "유럽 플렉서블 디스플레이 시장동향" 디지털 타임즈 구글 이미지 검색 키워드 DISPLAY, FLEXIBLE
