iPad Pro with OLED screen – rumor
It is expected that Apple intends to equip the iPad Pro line with a mini LED screen from the first quarter of 2021. But now there are rumors, shared by The Elec, who claim that Apple will switch to OLED afterwards and upcoming iPad Pro with OLED screen will be introduced in the market.
Devices with a mini LED screen still have an LCD screen. But the technology behind it, which relates to the lighting, ensures that those screens can be set brighter, use energy more efficiently and there is a low chance of burn-in. Apple would like to use such screens for its iPad Pro line. Even noted analyst Ming-Chi Kuo, who is closely watching Apple, believes these are the plans of the Cupertino company. The 12.9 inch model would be next, then the 11 inch version.
Now there is a rumor that claims that Apple will still opt for OLED afterwards. The displays should be supplied by Samsung and have a low risk of burn-in. This is because a new way of producing is used. This is evident from the following text from the article:
Samsung Display was renovating one of its production line at its A4 factory in Asan to produce the OLED screens for the iPad. The company was adding a distribution chamber to the organic material deposition chamber to deposit red, green and blue in tandem. This will allow the firm to deposit one layer of RGB, send the substrate back to the front of the production line, and stack an emitting layer atop it.
Tandem structure allows two to three emitting layers to be stacked. This is done to extend the life of the emitting layer compared to using just one layer.
Apple was requiring higher specs for the OLED that will be used for its iPad Pro from Samsung Display and LG Display compared to screens that provide for iPhones, people familiar with the matter said.
The Elec also makes the note that the iPad Pro with an OLED screen can still take a little longer, if, for example, there would be a lot of demand for iPad Pros with a mini LED screen. If the reporting is correct, it seems that Apple is using the Pro with a mini LED display as a kind of sprinkler board for the switch to OLED.
