"After the completion of merger with Quanta Display Inc. (QDI), the loss of QDI for the previous two quarters of 2006 has been turned around through the better product integration and cost structure, even though we amended the rate of fab loading in 4Q because of an early sign of controlling year end inventory from some of our customers,” said Mr. Max Cheng, Vice President and Chief Financial Officer of AUO.
