OLED screens are still surprisingly expensive IME, especially at the high quality Apple procures. It's $200 for a modern iPhone screen itself on eBay, and adding labor plus Apple tax it doesn't seem that insane.
>OLED screens are still surprisingly expensive IME
OLED has actually been cheaper than LCD since 2020 for Mobile Display Panel at the same PPI. Even at it peak ( iPhone X ) including glass it wouldn't cost Apple more than $120. Right now it down close to $80. Mostly because Apple insist on using flexible display and how they blend the notch.
There are plenty more OLED cost optimisation coming in the next 10 years.
News at 11: Apple aftersale parts are extremely expensive. Be prepared to pay for two third of a new iPhone or Macbook if their mainboards go south in the case they do not fall under Apple warranty program.
