1-1 Introduction the semiconductor industry
1. Semiconductor industry
Semiconductors are extremely important in virtually all areas of life. They are vital for many consumer products.
This industry has changed society in uncountable ways. Semi- conductors are installed in virtually all technical equipment, ranging from dish- washers, microwave ovens and flat screens to machine to
organic light emitting diode(OLED)
LED's 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 transistor
Organic Light Emitting Diode(OLED)
An OLED is an electronic device made by placing a series of organic thin films between two conductors. When electrical current is applied, a bright light is emitted
A device that is 100 to 500 nanometers thick or about 200 times smaller than a human hair
