This pocket television was the first actual LCD television set, launched in 1983. It was a monochrome (black & white) set with a greyscale output. With this tv the contrast was poor thus pure black and white images were not possible, and brightness did little to clear a blurred image. These were early days however and with the Epson ET-10 revealed in Nov 1983 and launched in 1984, the definition was greatly improved with over 50000 pixel LCD, and vibrant colour images. In strictly electronics terms in the 1980's the high definition Cathode Ray Tube could not be beaten for crystal clarity and pure colour. More recently large screen LCD tv's are now providing greater pixels and thus hi definition, although they still lack the high contrast and brightness of the old CRT tv's. Recent experiments to increase the contrast & brightness have meant the LCD tv's use additional LED backlighting, meaning extremely high power useage of between 500-1000 Watts (depending on screen size). This makes them energy inefficient, and so their manufacture may be banned in future.
