Sources say Samsung has been approved to begin mass production of OLED panels for four models of Apple's iPhone 15 series.

CTOnews.com, August 1, according to TheElec, four Apple iPhone 15 displays are in the final PVT stage. Samsung shows that it has entered the stage of mass production today after obtaining Apple's approval, and will provide display panels to four iPhone 15 models.

Samsung is the only one of the three major suppliers of iPhone 15 screens to start mass production so far, the report said.

In addition, LG shows conditional approval, but the company must make one or more improvements before starting mass production of the iPhone 15 Pro display panel, which is expected to meet mass production conditions soon and is expected to receive mass production approval for the Pro Max model. By contrast, BOE, which won the iPhone 15 / Plus order, seems to face some difficulties.

CTOnews.com Note: after the development of the prototype, it is generally divided into four stages before the official release. Apple supply chain manufacturers are already preparing for the mass production of the iPhone 15 series:

EVT (Engineering Verification Test)

DVT (Design Verification Test)

PVT (product verification testing)

In the final stage of mass production, the supplier operates at full capacity.

It is worth mentioning that TheElec also mentioned that the periscope lens module of the iPhone 15 Pro Max encountered a mass production interruption, and the lens of the series was provided by LG Innotek and the sensor provided by Sony. The rate of return is said to be lower than expected.
