Canon Inc. said on Thursday it would start making OLED displays next year as part of a plan to bring more production of key parts in-house and lower procurement costs. Canon President Fujio Mitarai said the company planned to use OLED displays in its own digital cameras, camcorders and printers as early as the second half of 2006, replacing LCD. It had already produced a prototype. "We won't make these for sale to other companies. We use about 20 million (displays each year) on our own so that's a big enough cost savings right there," Mitarai told reporters on the sidelines of a meeting with analysts and investors.
