New Era of Energy Efficient, Flexible, Thin Display Technology “OLED TECHNOLOGY”

Abstract

OLED is a LED in which emissive electroluminescent layer is a film of organic compound that emits light in
response to electric current. This article is a study of advancement in various technologies and methods that lead to the
improvement of qualities of OLED display and is also study of various parameters which will lead to complete replacement
of conventional displays with modern OLED displays .OLED can be fabricated using polymers or by small molecules in flat
penal display zone .Unlike traditional displays OLED’S are self luminous and do not require any kind of backlighting. This
eliminates need for bulky and environment undesirably mercury lamps and yields a thinner and more compact displays.
Thus it can display deep black levels and can be thinner and lighter than liquid crystal display.In low ambient light
conditions(such as dark rooms),an OLED screen can achieve a higher contrast ratio than an LCD regardless of whether the
LCD uses cold cathode fluorescent lamps or an LED backlight.OLED’S are biodegradable. OLED’S have wide viewing
angle of about 1800
and their low power consumption (only 2 to 10v)provides for maximum efficiency and helps in
minimizing the heat and electric interference in electronic devices .these are cheaper,sharper,thinner and flexible
displays.OLED’S may lead to future applications in head up displays, billboard type displays. OLED’S refresh faster than
LED’S(almost 1000 times).A device with an OLED display changes information in real time .
