Report: Apple working on micro-LED displays at "secret" Taiwan factory
Micro-LED screens also offer higher resolution and a better color gamut. But there is a major drawback. When used in a TFT (thin film transistor) manufacturing process, the yields are unacceptable. This makes mass production of the screen extremely difficult. But that is what Apple is working on in the Taiwan facility. If it can improve the yields, micro-LED could become a challenger to OLED, according to Digitimes Research analyst Jessie Lin.
Apple has been rumored to be considering a shift to OLED screens for the Apple iPhone. However, KGI Securities analyst Ming Chi-Kuo, who has an amazing track record with his Apple forecasts, says that an iPhone sporting an AMOLED screen won't take place until 2019 at the earliest.
