Apple is already looking ahead, even as its OLED screens are just starting to gain traction. Currently, Apple's iPhones rely on OLED displays supplied by Samsung. Despite optimizations, issues such as screen burn-in and display anomalies still persist. Recognizing these limitations, Apple has been actively exploring microLED technology, a move that reflects its long-term commitment to innovation and control over key components.
Although the iPhone with an OLED screen was recently launched, Apple’s technological journey doesn’t end there. According to reports from foreign media, the company is accelerating the development of a next-generation display technology known as microLED. This advancement is expected to eventually replace OLED screens in the coming years.

MicroLED technology builds upon the strengths of OLEDs, offering improvements in brightness, color accuracy, and energy efficiency. These enhancements make it a promising candidate for future Apple devices.
However, the path to microLED adoption isn't without challenges. A recent report from Taiwanese media DigiTimes suggested some concerns, stating that Apple has reduced its microLED R&D team in Taiwan. The company is working through several manufacturing hurdles. Earlier this year, Apple reportedly conducted small-scale trials of microLED products at a lab in Taoyuan, Taiwan.
According to upstream LED suppliers in Taiwan, the decision to focus R&D efforts in Taiwan was strategic. It allows closer collaboration with panel manufacturers and facilitates quicker implementation once the technology is ready.
Despite this, progress has been slow due to delays in the large-scale transfer of microLED chips onto substrates. As a result, Apple has scaled back its microLED development team in Longtan, northern Taiwan. Industry sources suggest that the slow development of mass transfer technology could hinder panel makers from achieving full-scale production soon, potentially leading Apple to reevaluate its R&D strategy.
Some insiders believe that the reduction in team size is due to the completion of initial research, with the U.S.-based team now taking over for further development. While the overall microLED team remains intact, its structure has changed, and members have shifted to other projects.
This shift also highlights Apple’s growing collaboration with TSMC, as the two companies work together to tackle manufacturing challenges, particularly in the application of silicon-based backplanes for microLED chips.
Apple has been exploring microLED since 2014, when it acquired LuxVue, a company specializing in the technology. Just like with OLED, it’s likely that microLED will first appear in the Apple Watch before making its way to the iPhone. There were even hints that the Apple Watch Series 3 was initially planned to use microLED, but technical and production issues delayed the rollout. It’s possible that the next generation of Apple Watch could feature microLED screens.
Currently, most OLED screens on the market are supplied by Samsung. Even after optimization by Apple and Samsung, users have reported issues such as screen lines and burn-in, especially in models like the iPhone X.
Given the competitive dynamics between Apple and Samsung, whether it's about reducing dependency on Samsung or improving user experience, Apple's resolve to develop microLED technology remains strong. The company is determined to take control of its display future, and microLED is a key part of that vision.
