Japan Display, a main supplier of liquid crystal display (LCD) panels for iPhones, generates about 60 percent of its revenue from Jobs' Mob.

The Nikkei Business Daily reported that the US tech giant plans to introduce four 5G iPhones with three different screen sizes with the OLED (organic light-emitting diode) technology.

OLED displays are generally thinner and allow more flexibility than LCD screens.

Apple first used OLED displays in its iPhone X in 2017 but this is the first time it will use the more expensive technology for all models in its top of the range phone.

Japan Display, has had net losses for six straight years, lags behind competitors in OLED development, only a relatively few OLED screens for wearable devices.
