Apple’s push to equip future iPhones with a more efficient OLED screen technology called Color Filter on Encapsulation (CoE), which promises both brighter displays and reduced power consumption by eliminating the polarizing layer, won’t arrive until late 2029 — the plan has reportedly been pushed back much further than anticipated.
What’s Behind CoE OLED, and What’s Being Delayed
CoE OLED removes the polarizing layer used in current OLED displays. That layer helps minimize screen blur, especially under conditions like wide viewing angles. Without it, screens can be made thinner and brighter while consuming less power — a compelling upgrade for iPhones. But the process of preserving display clarity without that layer has proven complex and risky at scale.
Until recently, projections had CoE OLED debuting in the 2027 iPhone lineup — specifically the model marking the 20th anniversary — likely the “Pro” version. However, recent research from UBI Research suggests that CoE won’t reach Apple’s phones until the Pro models ship in late 2029. In short: what was once expected in just over a year is now delayed a full two years beyond that. Apple reportedly believes the technology hasn’t matured enough to offer consistent manufacturing quality at required levels — plus, the cost penalties would be difficult to justify given already rising iPhone prices. Details were raised in ET News, which highlighted both immaturity and cost concerns as principal barriers.
Not the First, Not the Only Company
Some companies aren’t waiting. Samsung, for example, is believed to have used a version of CoE OLED in its Galaxy Z Fold3 back in 2021. This makes Apple’s delay stand out — it’s choosing caution over being first. The research also noted earlier expectations that Apple’s iPhone “Duo” series might adopt CoE, but so far no component-level teardown has confirmed that.
Despite the postponement, Apple is expected to press ahead with CoE in future Pro-tier iPhones, once the technology becomes reliable and cost-effective. For now, though, it remains a promise for the near future — just not the imminent one many analysts hoped for.
Bottom line: The wait for visibly brighter, more efficient iPhone displays is getting longer. What seemed like an upgrade for 2027 will now likely only reach customers in 2029.
What this means: Apple appears prioritizing product reliability, scale in manufacturing, and keeping costs under control, even at the expense of being first to adopt. For consumers, expectations should shift — CoE OLED is still coming, but it’ll arrive closer to when Apple’s pressure around price, battery life, and screen performance have only increased. It’s worth watching how this shapes expectations for the iPhone 20 lineup and whether competitive pressure from Samsung, LG, and others will force Apple’s hand earlier than planned.
