The Department of Justice today said a third executive from Chi Mei has plead guilty to antitrust charges of price fixing for LCDs. Wen-Hung Huang admitted to conspiring with other companies to keep screen prices artificially high between 2001 and 2006. The senior staffer's bargain will give a lighter sentence of nine months in jail and a $25,000 fine in return for cooperation that could lead to other convictions.
