For the new iPad Pro, Apple Vision Pro is rumored to have developed parallel OLED screen technology.

Apple Vision Pro: Inside the Apple Vision Pro
Tandem Mini OLED Displays, a display panel stacking method used on the M4 iPad Pro, could be a future version of Apple Vision Pro. Apple’s M4 iPad Pro introduced many changes, but the display technology is one of the most significant. Apple switched from mini-LED backlighting to a display called Tandem OLED. In a report published on Wednesday by SisaJournal, it appears that Samsung Display and LG Display are now working to make Tandem OLED compatible with micro OLED panels. The goal is to widen the technological gap between the two companies and their rivals in China. Tandem OLED is the stacking of two OLED layers to increase brightness and improve power consumption. Samsung and LG are looking to apply this technique to Micro OLED screens. Micro OLED displays, as the name suggests, are produced with tiny pixels. The pixel density can reach thousands of pixels per inch. Apple uses this resolution level to produce displays for its Apple Vision Pro, a display that requires high resolutions on a small screen. Micro OLED uses silicon substrates instead of glass for better resolution, but this doesn’t always help with brightness. The Tandem OLED technique combined with Micro LED should produce a brighter display. The report states that the timing of the introduction of Tandem Mini OLED displays by Samsung and LG will depend on the companies’ investment in commercializing it. LG has a clear advantage in Tandem OLED due to its use of it for automotive products and for OLED iPad Pro models. Samsung Display also produces Tandem OLED panels in large quantities for Apple and has gradually increased its share of iPad Pro display shipments. Sony is the supplier of Micro OLED displays for the current generation Apple Vision Pro. The exact date of when this will occur is not known, but it’s likely to be measured in years, or even never.
