ABSTRACT
Optoelectronic technology is making an ever-increasing impact on home and social life, with the ubiquitous TV set being a feature in almost every dwelling. The development of electrically powered artificial lighting has made a dramatic effect on people's lives, both at work and in the home, offering convenient illumination and removing the fire risks from candles and from oil and gas lamps. The first electrical lights used incandescent carbon filaments, formed from charred organic fabric threads, which were heated by electrical currents. John Logie Baird made the first demonstration of televised moving images in 1926, but this was achieved using a very crude electromechanical system to record and display the images. The latest advances in the technology are helping to make 3D TV more common and are also directed at producing the flexible or curved screens discussed earlier to allow a more cinematic home movie experience.
