  • Electroluminescent devices comprising bus bars
    Patent number: 8278137
    Abstract: A method for manufacturing an organic semiconductor device having a plurality of pixels, said method comprising: providing a substrate comprising a patterned layer of well-defining banks (308); depositing a first conductive material (310, 312) in the wells and over the well-defining banks (308), the first conductive material forming first electrodes (310) in the wells and bus-bars (312) over the well-defining banks (308) with an electrical break therebetween; depositing an organic semiconductive layer (318) over the first electrodes (310) in the wells; and depositing a second conductive material (320) over both the organic semiconductive layer (318) and the bus-bars (312) forming a continuous second electrode (320) over the organic semiconductive layer (318) and the bus-bars (312).

  • Organic Thin Film Transistors, Active Matrix Organic Optical Devices and Methods of Making the Same
    Publication number: 20100264408
    Abstract: A method of manufacturing an organic thin film transistor, comprising: providing a substrate comprising source and drain electrodes defining a channel region; forming a patterned layer of insulting material defining a well surrounding the channel region; depositing a protective layer in the well; subjecting exposed portions of the patterned layer of insulating material to a de-wetting treatment to lower the wettability of the exposed portions; removing the protective layer; and depositing organic semiconductive material from solution into the well.
