Sharp may have mounds of debt and falling sales, but it has one thing that China's Foxconn doesn't -- display technology used by Apple and others. That's reportedly why Foxconn has bid 625 billion yen ($5.4 billion) to buy the troubled company, according to the WSJ. That bid is over double the 300 billion yen ($2.6 billion) offered by an Japanese investment fund called Innovation Network Corp. In addition, Foxconn will absorb all of Sharp's considerable debt -- the company has a 510 billion yen ($4.4 billion) payment due soon on a series of loans to Japanese banks, for example.
