Fear of flexible “OLED panel crumple” is one of the reasons why Apple would probably use hybrid OLED for the iPad
So what is a hybrid OLED panel? It is a panel that uses a combination of rigid and flexible OLED technologies. For example, a hybrid OLED panel would use rigid glass as a foundation with a plastic layer of flexible thin-film OLED on top. Apple does not want to use flexible OLED panels alone because they tend to crumple. This occurs from the heat used by lasers to remove a glass substrate that starts out as part of a flexible OLED panel during its production.

Besides being less likely to crumple, Apple might also like that hybrid OLED panels are thinner than rigid panels and should also be cheaper to produce than flexible panels. Apple currently uses flexible OLED panels for the iPhone. The report notes that if the issues (including the propensity of these panels to crumple) can be resolved, Apple could choose to use flexible OLED panels for the iPad instead of hybrid panels.
Mini-LED displays give users some of the same features as OLED panels
Mini-LED backlit screens deliver some of the same features that users receive from OLED displays. The mini-LED displays use smaller LEDs as a backlight. Because of their smaller size, as much as 120 times smaller than the ones employed on traditional LCD screens, these panels have a larger number of LEDs behind the scenes. As a result, instead of the 72 LEDs used on the previous 12.9-inch iPad Pro model, there are 10,000 mini-LEDs used on the current model. They are arranged in four “dimming zones,” each with 2,500 mini-LEDs, to provide the super 1,000,000:1 contrast that these screens can offer.
Keep in mind that mini-LED panels are considered the next step in LCD display technology. So even if Apple were to use it for all of its iPad models, the company would probably continue working toward the ultimate goal of offering OLED-screened iPad models. Due to cost though, we’d expect Apple to offer such a feature first on the pricier 12.9-inch iPad Pro just like it is doing with mini-LED.
