Organske svetleče diode

Baš, Anže (author), Smole, Franc (mentor)

V magistrski nalogi je predstavljen OLED element in njegova uporaba v sodobnih aplikacijah. Na začetku je opisana kratka zgodovina raziskav OLED elementov in njihovega uvajanja v praktičnih aplikacijah. Nato je predstavljena osnovna in bolj kompleksna struktura OLED elementov ter njihovo delovanje. Definiran je tudi izkoristek OLED elementov in opisano, kako se da izkoristek povečati s pomočjo dopiranja. Podani so tudi najpogosteje uporabljeni materiali za posamezne sloje OLED elementov. V nadaljevanju je predstavljena ena glavnih aplikacij OLED elementov za TV zaslone in kratka primerjava OLED zaslonov z LCD zasloni. Opisan je proces izdelave OLED TV zaslonov in tudi tipi zaslonov, ki obstajajo na tržišču. V zaključnem delu naloge smo opisali, kako lahko OLED elemente uporabljamo kot velikopovršinske svetlobne panele, v kakšnih aplikacijah bi jih lahko uporabili in težave, ki jih srečujejo proizvajalci pri njihovi izdelavi. Narejena je tudi primerjava med organsko svetlečo diodo in anorgansko svetlečo diodo.

Abstract

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
