On-demand patterning for organic light-emitting diodes using laser irradiation
نویسندگان
چکیده
We investigated the patterning of organic light-emitting diodes using a blue laser irradiation after making uniform device. Laser was carried out under ambient atmosphere layer deposited. The part quenched, and it shown that optional possible. This technique is expected to be fabrication for on-demand pattern emission. photograph shows an example hiragana character “to”.

simulations for organic light - emitting diodes
The physical and chemical properties of tris(8-hydroxyquinolinato)aluminum (Alq3), one of the organic materials most commonly used as the light-emitting layer of OLEDs, and the interface with possible metal cathodes are investigated by means of first-principles computer simulations. A number of new insights have emerged from this study, and we emphasize the consequences of the properties thus d...
متن کاملOrganic Light-emitting Diodes and Organic Light-emitting Electrochemical Cells Based on Silole-Fluorene Derivatives
Silole groups are known to present a high electron affinity. Initially, copolymerization of siloles with fluorene was aimed at improving electron injection into the polymer layer and so improving the electroluminescent properties of Organic Light Emitting Diodes (OLED’s) made from fluorene. But it also provides the ability to turn the light emission colour to the green part of the spectrum and ...

This work reports on simulation and experimental investigation into the charge transport and electroluminescence in a quantum well (QW) organic light emitting diode (OLED) consisting of a N,N′-di(naphthalene-1-yl)-N,N′-diphenylbenzidine (NPB) as a hole transport layer, tris (8-hydroxyquinoline) aluminum (Alq3) as a potential barrier and electron transporting layer, and rubrene as potential well...
متن کاملDegradation in Organic Light Emitting Diodes
The objective is to fabricate organic light emitting diode and to study its degradation process in atmosphere condition in which PFO as an emitting material and PEDOT:PSS as a hole injecting material were used on ITO substrate. Thus degradation process of the OLED was studied upon its current-voltage characteristic. By fabricating this OLED and obtaining blue light and analysis of current-volta...
متن کاملBubble formation in organic light-emitting diodes
Bubbles in organic light-emitting diodes can be formed from gas release due to Joule heating effect at localized electrical shorts during operation, which could be simulated by a rapid thermal annealing. The gases in the bubbles consist of not only adsorbed moistures but also the decomposed organic species, which are detected in situ in an ultrahigh vacuum chamber. In the device of Al/tris-~8-h...
