The launch of the iPhone 12 may be delayed after a display supplier failed to complete the first delivery of OLED panels for Apple's next-generation flagship.

According to a report from Korean website DDaily (via MacRumors), BOE, the display manufacturer Apple commissioned to provide panels for the two least expensive iPhone 12 models, failed to pass OLED quality certification. BOE's displays are rumored to be used in the 5.4-inch iPhone 12 and 6.1-inch iPhone 12 Max, and may be the first Apple smartphone to feature an under-display fingerprint sensor.

The report does not address whether the BOE's failure to authenticate caused a significant setback for the release of the iPhone 12. However, given the already shaky production start date for the new device, one can conclude that this is not good news for those hoping to pocket the iPhone 12 in September.

In the past, Apple has relied on Samsung as its primary supplier of iPhone displays. Samsung is still on the hook for a variation of the iPhone 12 Pro, which could feature a 120Hz refresh rate. Cupertino had hoped for BOE for non-Pro iPhone 12 models, but DDaily reports that Apple may be forced to switch gears and hire another supplier instead.

In response to the report, Front Page Tech host and leaker Jon Prosser tweeted, "Samsung & LG OLEDs for iPhone 12 then."

BOE is a leading international manufacturer of LCD screens and already provides displays for the iPad and MacBook; according to MacRumors, BOE has been working on flexible OLED displays for Apple's smaller devices since last year.

The four rumored iPhone 12 models (5.4-inch iPhone 12, 6.1-inch iPhone 12 Max, 6.1-inch iPhone 12 Pro, and 6.7-inch iPhone 12 Max) all feature OLED panels and Apple's A14 Bionic chip. Each will also support 5G.

The iPhone 12 lineup will be unveiled at Apple's fall keynote alongside the Apple Watch 6. iPhones have been released every September, but health and safety constraints have led many to believe that the iPhone 12 production cycle has been delayed. Apple could still hold an event in September and release the device in October or November.
