electronics firms

Three Asian electronics firms have agreed to plead guilty and pay $585 million in fines for conspiring to drive up the prices of LCD screens used in computers, TVs, cell phones and other electronic devices.

In a plea deal filed Wednesday, LG Display Co. Ltd., Sharp Corp., and Chunghwa Picture Tubes Ltd. agreed to cooperate in an antitrust investigation headed by the U.S. Justice Department. The plea agreement was filed in federal court in San Francisco.

LCDs, or liquid crystal display monitors, are the glass display screens on many laptop computers, cell phones and new TVs.
