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.
