Apple’s two-decade iPhone milestone could coincide with a notable shift in display engineering. Supply chain inputs indicate that the 20th anniversary Apple iPhone may adopt a custom OLED panel developed by Samsung, built around a pol-less architecture and a four-sided curved display.

Samsung-Apple display relationship has remained steady since the first OLED iPhone. Now, Weibo leaker DCS claims that Apple and Samsung are collaborating on the development of a pol-less four-sided curved display for the 20th anniversary iPhone.

A four-sided curve pushes the screen-to-body ratio closer to a true edge-to-edge finish. It is something Apple has approached incrementally over several generations.

The reported move to a polariser-free OLED points to Color Filter on Encapsulation, or COE integration, a method Samsung has been refining for its own premium panels.

By eliminating the traditional polariser layer, the stack becomes thinner and allows more emitted light to pass through. The result is improved brightness at a lower power envelope, a balance.

For Apple, the anniversary iPhone is an opportunity to reset expectations. Edge gestures become more fluid when the transition from frame to display is less abrupt.

From a strategic standpoint, the shift underscores Samsung Display’s continued role at the high end of the OLED supply chain.
