Toshiba Corp is to expand its production of liquid-crystal diode display screens: as well as planned production from its Display Technologies Inc joint venture with IBM Corp, which will produce 17,000 colour thin-film transistor screens per month, Toshiba plans to start trial production of 1,000 medium-sized screens per month at its Fukaya plant in Saitama near Tokyo from this month; low yields have been a problem at the Display Technology joint venture plant and plans are afoot to increase yields through use of new vapour deposition and inspection equipment developed jointly with US device manufacturers; the joint venture is to produce a range of screens including the current 10 type, as well as a 13.8 one for engineering workstations; Toshiba’s own Himeji plant next door to the Display Technologies plant is to manufacture 5.9 screens for supply to Toyota Motor Co for use in cars, at a rate of between 10,000 and 20,000 of the things per month.
