In this master thesis is presented the OLED element and its use in modern application.
In the beginning we describe a short history, when and how the first research in using OLED elements began and when and in which applications it first appeared. Then we presented the basic and more complex structure of the OLED element and how it works. We also defined the efficiency of the OLED element and describe how to increase this efficiency using a doping method. Given are also the most frequently used materials for each layer of the OLED element.
Further we present one of the main applications of the OLED element, that is in TV screens and a short comparison between OLED displays and LCD displays. We described the process of making OLED TV screens and what types of displays exist on the market.
In the final part of the paper we described how to use OLED elements for large area OLED lighting panels and in which applications we could use them in and the difficulties encountered by the manufacturers in their creation. Then there is a comparison made between an organic light emitting diode and an inorganic light emitting diode
