Possibly buoyed by margins produced by its $2500 XEL-1, Sony is pumping 22-billion yen ($203.5 million) into scaling OLED production technology up to medium and large panels. No word on what sort of sizes are meant by "medium" and "large," but we're hoping that "medium" comes in around 30-inches and "large" runs upwards of the 45-inch mark. Competition being what it is, Sony probably hopes so, too. With OLED lifetimes on the rise, the only thing that keeps these power-miserly, high-contrast, great color and wide-viewing angle displays out of a home theater setup is sheer size. Given the race between manufacturers, we're hoping to see falling prices, rising sizes and shorter times to market.
