People who buy a new 2018 iPhone will stick with the cheaper version that has an LCD screen, not the more-expensive OLED-based phones.

Apple is rumored to be working on two organic light emitting diode (OLED) screen phones for its new 2018 lineup, expected in September, and just one with a traditional liquid crystal display (LCD) screen. But the LCD version will cost less and deliver better sales, according to a report from The Wall Street Journal citing people involved in Apple's supply chain.
