Apple's first OLED MacBook Pro models have cleared a major manufacturing hurdle, with panel supplier Samsung Display having reportedly achieved yields above 90 percent on its Gen 8.6 OLED production line.

According to Korean publication The Elec, some individual process stages are now reaching yields as high as 95 percent, a level that the display industry considers "golden yield" territory for stable mass production.

The report says Samsung could begin shipping OLED laptop panels through the supply chain as early as June. The panels are expected to be used in future 14-inch and 16-inch MacBook Pro models, with estimated supply volumes of around 2 million units this year.

The rapid yield improvement is notable because OLED laptop panels are a lot harder to manufacture than smartphone displays due to their larger size and stricter brightness and lifespan requirements. For example, MacBook Pro panels are expected to use brighter tandem two-stack OLED technology like Apple's OLED iPad Pro models, oxide TFT backplanes for improved battery life, and an anti-moisture sealing protection method called hybrid encapsulation.

Samsung began its Gen 8.6 IT OLED investment in 2023 and is currently operating one of two planned production lines. Depending on demand for the OLED MacBook Pro models, which will reportedly have touchscreen capability for the first time, Samsung could activate the second line and expand capacity further.

Bloomberg's Mark Gurman has repeatedly stated that 14-inch and 16-inch OLED MacBook Pro models are slated to launch in late 2026 to early 2027, but the latter time frame is now said to be more likely due to the industry-wide chip shortage.
