Patterning-free integration of polymer light-emitting diode and polymer transistor

چکیده
We demonstrate an integration of polymer light-emitting diode ~LED! and polymer transistor in which no patterning of the organic layers is needed. Intrinsic high-mobility semiconducting conjugated polymer poly~3-hexylthiophene!~P3HT! is used as the hole-transport layer for polymer LED. The light emission efficiency is only slightly lower than the LED with conventional heavily doped hole-transport layer. Such LED is easily integrated with a P3HT transistor without patterning. © 2004 American Institute of Physics. @DOI: 10.1063/1.1728301#

Light-emitting polymer space-charge-limited transistor
Polymer light-emitting transistor is realized by vertically stacking a top-emitting polymer light-emitting diode on a polymer space-charge-limited transistor. The transistor modulates the current flow of the light-emitting diode by the metal-grid base voltage. The active semiconductor of the transistor is poly 3-hexylthiophene . Yellow poly para-phenylene vinylene derivative is used as the yell...
متن کاملOrganic thin film transistors and polymer light-emitting diodes
To fully realize the advantages of organic flexible electronics, patterning is very important. In this paper we show that a purely additive patterning technique, termed polymer inking and stamping, can be used to pattern conductive polymer PEDOT and fabricate sub-micron channel length organic thin film transistors. In addition, we applied the technique to transfer a stack of metal/conjugated po...
متن کاملMask-free photolithographic exposure using a matrix-addressable micropixellated AlInGaN ultraviolet light-emitting diode
We report the integration of a UV-curable polymer microlens array onto a matrix-addressable, 368-nm-wavelength, light-emitting diode device containing 64364 micropixel elements. The geometrical and optical parameters of the microlenses were carefully chosen to allow the highly divergent emission from each micropixel to be collimated into a narrow beam of about 8-mm diam, over a distance of more...
متن کاملPatterning polymer light-emitting diodes by micromolding in capillary
Here we describe a method of patterning electroluminescent (EL) polymers using micromolding in capillary (MIMIC). MIMIC is the one of the lithographic methods based on the microfludics among the soft lithography using a patterned poly(dimethylsiloxane) (PDMS) elastomer. The patterned microstructures of poly(dioctylfluorene) (PDOF), poly(p-phenylenevinylene) (PPV), and poly(2methoxy-5-2 0-ethylh...
متن کاملGraphene electrodes for organic metal-free light-emitting devices
In addition to its fascinating electrical and mechanical properties, graphene is also an electrochemically stable and transparent electrode material. We demonstrate its applicability as both anode and cathode in a light-emitting electrochemical cell (LEC), an electrochemical analogue to a polymer organic light-emitting diode. Specifically, we summarize recent progress in carbon-based metal-free...
