How Hot does the front glass have to be to starts to separate from LCD?

The point I was trying to get at is glass only on OLED is nearly impossible because of how fragile it is.

The pixel 2 uses an OLED panel, which are SUPER thin. Anything with an OLED panel is unfortunately very difficult to do a glass only repair on with a very high failure rate.

So how many degrees C° should I set my LCD separating machine at if it’s OLED ?

But it can be done right? Try using cold instead of heat,or would that matter when dealing with fragile OLED screens?
