Abstract:
A method for preparing an organic electronic or optoelectronic device is described. The method comprises depositing a layer of fluorinated polymer (103) on a substrate (101, 102), patterning the layer of fluorinated polymer to form a relief pattern and depositing from solution a layer of organic semiconductive or conductive material on the substrate (105, 106). The fluorinated polymer may be a fluorinated photoresist and may be treated by exposure to ultraviolet light and ozone prior to the deposition of the layer of organic semiconductive or conductive material. The method has particular application in the preparation of organic light emitting devices by ink jet printing.
Abstract:
Apparatus and methods for providing displays based upon the principle of photoluminescence quenching are described. The invention includes a method of displaying information using photoluminescence quenching, the method comprising: providing an optoelectronic display comprising a photoluminescent material between a pair of electrodes; providing illumination for the photoluminescent material to cause the photoluminescent material to photoluminesce; and biassing the electrodes to at least partially quench said photoluminescence.
Abstract:
This invention generally relates to display driver circuits for electro-optic displays, and more particularly relates to circuits and methods for reducing the re-emission of absorbed light, for example to increase the colour gamut of organic light emitting diode displays. A driver for a display comprising a plurality of light emitting diode display elements, the driver comprising addressing circuitry to address said display elements, a first driver to cooperate with said address circuitry to provide a forward drive to at least one of said display elements to illuminate the display element, and a second driver to provide a reverse bias drive to others of said display elements at the same time as said at least one display element is illuminated to reduce a level of photoluminescence from said others of said display elements.

Abstract:
A fuel cell assembly comprising a fuel cell incorporated in a composite laminate structure, the composite laminate structure comprising a core material within which the fuel cell is embedded. The fuel cell comprises an electrolytic membrane having first and second faces, and first and second electrodes disposed adjacent to the respective faces of the electrolytic membrane. The first and second electrodes are connectable to an electric circuit. The core material provides support to the fuel cell embedded therein and fluid communication through the core material, to enable the passage of one or more fluids to the first and second electrodes.
