Is it possible to use the regular iPhone 11 screen as a replacement?
I’m looking at replacing the screen on my iPhone 11 pro and was wondering if it’s possible to use the regular iPhone 11’s LCD screen as opposed to the Pro’s OLED?
No. It won't fit and the phone is not set to run an lcd screen. They will eventually come up with a cheap LCD screen but it can cause the cables to melt, the connections on the motherboard to melt and short the board.
The iPhone 11 and 11 pro actually have slightly different screen sizes, so they won’t even be able to fit.
It is not directly possible to use an iPhone 11 screen in an iPhone 11 Pro because the 11 Pro is smaller (6,1 inches vs 5,8 inches) and uses an OLED screen, not an LCD. But iFixit offers an LCD replacement screen which is a little bit cheaper then the OLED one. LCD replacement screen.
You just have to keep in mind that the image quality of an OLED screen is higher.
