OLEDS PAPER PRESENTATION






Abstract:
            This paper deals with the study of OLED, its structural details. OLEDs are light weight durable power efficient, and ideal for portable applications. OLEDs have fewer process steps and also use both fewer and low cost materials than LCD display. A feed back circuit for OLED based display is proposed and demonstrated.
               The plastic substrates are thinner, lighter, shatterproof, flexible, rollable and foldable, making Silicon-on-Plastic an enabling technology for new applications/products. This paper studies the development of Silicon on Plastic technology. Advances in poly-silicon technology have expanded TFT (THIN FILM TRANSISTORS) technology to high-speed electronics applications such as Smart Cards, RFID tags, portable imaging devices, photo-voltaic devices and solid-state lighting and other integrated circuit functions.
              The challenge of Silicon-on-Plastic technology is to overcome the fact that plastic melts at the temperature required to build transistors in conventional TFT processes. Technological innovations have been made to accommodate silicon processing at low temperatures.  This paper describes an innovative ultra-low temperature poly-silicon TFT process on plastic substrates , Key technologies includes near room-temperature silicon and oxide deposition steps, laser crystallization and dopant activation.
             Manufacturing issues related to plastic material compatibility in a TFT process are reviewed. Lamination and de-lamination of plastic wafers to glass carrier wafers for manufacturability is discussed. An active matrix TFT backplane will be fabricated with anOLED(Organic Light Emitting Diode) display to demonstrate this technology.
