The Sharp Corporation was founded in 1912 by Tokuji Hayakawa and takes its name from one of our founder's first inventions, the Ever Sharp propelling pencil, developed in 1915. Sharp has continued this creative tradition, developing technologically innovative products to enhance our lives, add to our comfort, broaden our perspectives and boost our productivity. Sharp is recognised for its pioneering research into Liquid Crystal Display (LCD) technology.
Sharp introduced the first LCD electronic calculator back in 1973. Since then, it has continued to develop revolutionary LCD products such as the ViewCam, Ultra-Lite notebook pc and touch-screen personal organisers. Perhaps the best illustration of the impact of liquid crystal display technology on product development is with the simple calculator. Sharp introduced the world's first all-transistor desktop calculator in 1964. By 1979, just 15 years later, Sharp announced the world's first super-thin (1.6mm) card sized calculator. Today, Sharp leads the way in LCD and is a worldwide developer of core technologies that will play an integral role in the development of digital technology such as optoelectronics, infrared, semiconductors and flash memory.
