AUGUSTA — Maine businesses and consumers who purchased LCD flat-panel screens from 1999 to 2006 may be entitled to a cash refund resulting from a billion-dollar price-fixing settlement with 10 manufacturers, according to Maine’s Attorney General’s Office.

A fund for the payments was set up after the manufacturers illegally conspired to raise the price of LCD flat panels used in televisions, monitors and laptop computers, according to the office. The deadline for filing is Dec. 6.

Eligible consumers could collect $25, $100, $200 or more depending upon the number of televisions, monitors and laptop computers purchased from 1999 to 2006. Businesses with large purchases could recoup thousands of dollars.

The AG’s Office said the easiest way to file a claim is to use the online claim form at www.LCDclass.com or call 1-855-225-1886 for more information.

Consumers and businesses are eligible for payments if they were residents of Maine or one of the other 23 settling states or the District of Columbia at the time of purchase. The other 23 states participating in the refund are Arizona, Arkansas, California, Florida, Hawaii, Iowa, Kansas, Massachusetts, Michigan, Minnesota, Mississippi, Missouri, Nevada, New Mexico, New York, North Carolina, North Dakota, Rhode Island, South Dakota, Tennessee, Vermont, West Virginia and Wisconsin.

The LCD flat screen manufacturers participating in the settlement are AU Optronics Corporation, Hitachi Ltd., Sharp Corporation, Toshiba Corporation, Samsung Electronics Corporation, Epson Imaging Devices Corporation, LG Electronics, Chunghwa Picture Tubes, HannStar Display Corporation and Chi Mei Optoelectronics.
