Hitachi Ltd announced yesterday that it is to end the manufacture of monochrome liquid crystal diode displays in Japan and shift production to its subsidiary in Taiwan. The wholly-owned Kaohsiung Hitachi Electronics Co Ltd will begin output of large monochrome displays in July or August of 1994 with new investment estimated at about $18 to $27m. The Taiwan unit already produces small- and mid-size monochrome flat panel displays, with sales worth some $65m a year. The Hitachi plant in Mobara, Chiba prefecture, making 50,000 full-size mono displays at a rate of 50,000 a month, will switch to colour ones.
