A display device comprising one or more sources of UV radiation (50); an LCD panel and two aligned tri-colour arrays. One array comprises filter elements (70) on one surface of the LCD panel, the other comprises phosphor elements (72) on the filter elements. The filter elements (70) each consist of one of three colour filters. The phosphor elements (72), when excited by UV radiation, each emit visible light in one of three colours. Filter and phosphor elements associated with the same colour are aligned with each other. The elements are preferably arranged so that ambient light falling on the front of the devices is at least partially reflected by the filters and/or phosphors. This can be achieved by controlling the spacing between filter and phosphor elements in relation to the width of an element. The arrangement can be used to provide a large scale colour display device comprising a plurality of modules (12). |
