In June 1983, Casio released the world’s smallest television. It was the TV-10, with its 2.7-inch black and white liquid crystal display. Research and development into LCD technology had been going on since 1974. The technology had been used for watches and calculators, but now it had progressed to the point where moving images could be displayed. In 1985, a color panel was developed, and the TV-1000 was released as a color LCD TV. After that, liquid crystal technology progressed from TN to STN and TFT, and now it is used for many kinds of products as a next-generation display replacing cathode-ray tubes.
