Sharp Corporation

is a Japanese multinational corporation that designs and manufactures electronic products. Headquartered in Abeno-ku, Osaka, Japan, Sharp employed 49,096 people worldwide as of March 2015. The company was founded in September 1912 and takes its name from one of its founder's first inventions, the Ever-Sharp mechanical pencil, which was invented by Tokuji Hayakawa (早川 徳次) in 1915. As of 2013, Sharp Corporation is the tenth-largest, by market share, television manufacturer in the world. Since 2000, Sharp has heavily invested in LCD panel manufacturing plants: Kameyama in 2004, Sakai in 2009. The Sakai plant is still the only 10th generation LCD manufacturing plant on the globe and best fit for production of 60 inch or larger panels. However, the 2008 financial crisis and strong Yen (especially against Won) significantly lowered world demand for Japanese LCD panels. Furthermore, the switch to digital TV broadcasting was virtually completed in Japan by the middle of 2011. Via Japanese government issued coupons for digital TV sets, consumers were encouraged to purchase digital TV sets until March 2011. This hit the Japanese LCD TV market, reducing it almost by half from 2010. All of those events strongly hit Sharp's LCD business. As the result, the Sakai LCD plant suffered a reduced operating rate until Q3 2012. 2012 was the 100th anniversary for Sharp but it announced the worst financial record in its history, with a loss of 376 billion yen (US$4.7 billion) in April 2012. In September, Sharp announced job cuts. In 2014, Sharp was able to stem losses and deliver a positive net income for its first quarter results. In July 2015, Sharp sold its Mexico TV factory to Chinese electronics manufacturer Hisense for $23.7 million with rights to use the Sharp brand name and all its channel resources in North and South America - meaning Hisense completely took over Sharp's TV business in those regions.
