Nature news cheap evening dresses australia online Opticalfibre fabric wedding dresses glasgow should open new horizons for fashion designers. Seen the movie, got the tshirt?Soon tshirts might not just advertise movies but show them.Researchers at france telecom have developed a fabric woven from plastic optical fibres that glow with a series of different images, like a tv screen1. It could mean never again being stuck wearing the same outfit as someone else at a party you could use a mobile phone to download a whole new look into the fabric from a computerized database. The batterypowered opticalfibre fabric should"Open new horizons for fashion designers,"Say its developers emmanuel deflin and coworkers of france telecom in meylan.In a more practical vein, they suggest that firefighters or police could wear clothing programmed to display safety or warning information visible from afar. So far the team has made a jacket containing a very lowresolution grid of eight by eight pixels, which displays crude yet readable symbols such as numbers. Switchable textiles have been made before from different lightemission devices.In principle, flexible and fully pixellated screens could be imprinted onto fabrics using plastic lightemitting diodes(Leds), for example.But fibreoptics are tough, cheap and easy to adapt to existing fabricweaving technology. Light show showing real movies on this fabric is, in truth, still remote.A tv or monitor screen contains a grid of pixels that can be lit up or left dark.Each fibreoptic thread in the fabric provides an entire row of pixels that can be configured in only one way.The row can be set up to contain some unlit and some lit sections when switched on, but that predetermined pattern can't be changed. The threads are optical fibres that leak light. Fora screen capable of supporting several different images, therefore, a different thread must supply each different configuration of light and dark patches in a row of pixels.This is not quite as limiting as it sounds, because the fibreoptic threads are little thicker than a human hair at about a quarter of a millimetre across. The screen could support four distinct patterns, for example, by selecting one of four strands for each line of the image.The glow from each bright part of a strand spreads out enough that, from a distance, the intervening dark strands are barely visible.Primitive moving images can be made by rapidly switching between several such preset pictures. The threads are optical fibres that leak light along the sections that need to glow.Normal optical fibres trap light inside, so that they look transparent from the side but glow at the far end where the light emerges. A french company called audio images has developed a way to perforate optical fibres with tiny holes that allow some of the light to escape sideways.Each section of a fibre then glows when light is fed into one end. Deflin's team uses plastic fibres, which are stronger than the glass fibres used for telecommunications.Light is fed into the fibres by tiny leds along the edge of the display panel and controlled bridesmaidescheap by a small microchip.Leds of different colours can be used for multicoloured images.
