摘要： First and second electrodes (3 and 4) are provided on respective ones (2' and 2") of the first and second major surfaces of a photoresponsive zone (2). The photoresponsive zone (2) is in the form of a polymer blend having regions (2a) of a first semiconductive polymer and regions (2b) of a second semiconductive polymer phase-separated from the first semiconductive polymer. The second semiconductive polymer has an electron affinity greater than that of the first semiconductive polymer so that, in use of the device (1), a photocurrent between the first and second electrodes (3 and 4) resulting from light incident on the photoresponsive layer comprises electrons travelling predominantly through the second semiconductive polymer and holes travelling predominantly through the first semiconductive polymer.

摘要： Apparatus and methods for providing displays based upon the principle of photoluminescent 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 photoluminescence, and biasing the electrodes to at least partially quench the photoluminescence.

摘要： 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 color 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.
