According to media reports, there are currently three screen suppliers for the iPhone 12/13 series, ranging in magnitude from Samsung, LG and BOE, of which BOE only supplies a small number of 6.1-inch standard OLEDs.
However, BOE has actually entered the Apple supply chain very early, and the Apple Watch has long used domestic panels.

According to the latest news, CSOT (China Star Optoelectronics), China's second largest screen factory, has formed a team to evaluate and verify the production line that supplies OLED panels for the iPhone.
It is said that the Huaxing Optoelectronics panel that Apple inspected for the first time came from the T4 factory in Wuhan. The data shows that T4 can manufacture six generations of flexible OLEDs, and the monthly production capacity can reach 45,000 substrates after the three-stage production.
But taking BOE as an example, before successfully supplying the iPhone, Apple failed the evaluation more than once, so it is foreseeable that CSOT will need a considerable period of time to finally enter the market.
