Such big spending could give Apple a jump on a new display technology known as IGZO (indium, gallium, and zinc) that can achieve a resolution of 330 dotsper inch while reducing the thickness and power consumption.
Dr Sheridon and his colleagues have created prototype displays with more than 200 dotsper inch (80 dotsper centimetre) about twice as fine a resolution as most laptop screens, but only half as clear as a decent laser printer.
Dye sublimation is a printing technology that uses layers of transparent color dye, special dye-receptive paper and a heated printing head to create images that are pretty close in quality to conventional photographic film and paper--up to 16.7 million colors and 403 dotsper inch by 403 dotsper inch.
