On December 9, 2009 the DOJ announced that Chi Mei Optoelectronics of Taiwan agreed to plead guilty and pay a criminal fine amounting to US$220 million for its participation in a conspiracy to fix prices in the sale of Thin Film Transistor-Liquid Crystal Display (TFT-LCD) panels. TFT-LCD panels are used in televisions, notebook computers, desktop monitors, mobile devices and other applications.

Between September 2001 and December 2006, Chi Mei allegedly agreed to sell TFT-LCD panels at certain prices during meetings and other communications in Taiwan, Korea and the United States. Chi Mei also issued price quotations in accordance with the agreements made in those communications and exchanged information on the sales of TFT-LCD panels to monitor and enforce the price fixing agreement.

The DOJ has obtained guilty pleas and agreements to pay criminal penalties from five other companies in association with its antitrust investigation into the TFT-LCD Industry: LG Display Co. Ltd. (US$400 million), Sharp Corporation (US$120 million), Chunghwa Picture Tubes Ltd. (US$65 million), Hitachi Displays Ltd. (US$31 million) and Epson Imaging Devices Corporation (US$26 million).
