Maybe, if they are really going this way with the non Pro models, their aim is to lower the cost and the price of both 6.1” iPhone and 5.4” iPhone mini. Maybe they think the mini could sell better with a lower price point, and they are going to try one last time.Except why would apple go backwards and remove OLED in the non-pro after introducing it in the 12 series?
I am reading that LTPS is a low power IPS LCD panel, even lower than IGZO, so maybe this makes it possible to have a low power screen at a lower price than OLED LTPO.
Just my 2 cents. But I really wish all iPhones come with OLED displays tbh.
