This is likely to damage an OLED panel, with parts of the image becoming permanently "burnt in" over time.
Also, tablet and laptop sized OLED panels are likely to be very expensive, because there is very little demand due to this problem.
So I doubt whether Apple will use an OLED panel in the next iPad, and therefore I doubt that it will be bezel-less.
I believe your premise is wrong, I don't believe a bezel-less display needs to be OLED. As one example, look at the Essential phone vs. other "bezel-less" Android displays. Granted, it still has a "chin," though a relatively small one, but all phones (other than the iPhone X) require the chin. Further, though we'll have to wait and see, the rumored "cheap" iPhone next year, that is supposed to be like the X just with LCD, is allegedly bezel-less.
Having said that, there doesn't seem to be the same push to get a tablet completely bezel-less. I think this is more because, with the size and weight of a tablet, you almost need some bezel to hold onto the tablet. I doubt the bezels on the new iPad will be significantly smaller than on the current iPad Pro. The one exception might be on the bottom, where the chin is reduced since they no longer need to fit the TouchID sensor, since the new iPad Pros are rumored to have FaceID.
