Foldable iPhone Challenges Apple to Innovate Display Technology: Moving from On-Cell to In-Cell to Solve the Crease Issue

Recent developments indicate that Apple is making significant adjustments to its display technology in anticipation of the much-anticipated iPhone Fold. The company’s goal is to reduce the noticeable crease that occurs where the screen bends. In a strategic move, Apple is transitioning from an on-cell touch sensor architecture to an in-cell design, which aims to enhance the device’s durability. This innovation is one of the factors contributing to the extended timeline for the launch of the foldable iPhone.

Apple’s Transition to In-Cell Design for the Foldable iPhone

According to Mark Gurman of Bloomberg in his latest Power On newsletter, Apple’s initiative to diminish the crease on the inner display involves a significant technological shift. To clarify, the traditional on-cell architecture positions the touch sensor layer either below the front glass or above the color filter polarizer. While this design enhances sensitivity and simplifies manufacturing, it can also lead to the formation of air bubbles, which worsen crease issues over time as the device is folded and unfolded.

Conversely, the in-cell architecture integrates the touch sensor beneath the color filter substrate, yet above the polarizer. This arrangement reduces air gaps, potentially resulting in a smoother display crease. It’s worth noting that Apple has previously employed this technology in its latest iPhone models, emphasizing a commitment to creating a seamless visual experience while adhering to increasingly stringent quality standards as the company evolves its devices.

Apple faces numerous challenges in this endeavor, including perfecting the hinge mechanism and achieving a crease-free display. The combination of these factors could explain the delay in launching its first foldable iPhone compared to competitors like Samsung and Google. Apple’s extensive research and quality implementation within this category could position the device to lead in the market, setting a new standard for rivals.

Furthermore, Apple’s transition to in-cell touch sensors indicates its rigorous efforts in testing and refining new technologies to enhance user experience. Gurman’s report also highlights that the upcoming foldable iPhone will be equipped with the company’s custom C2 modem for superior connectivity and efficiency. Additionally, there will be a revival of Touch ID integrated into the power button. Stay tuned as we provide further updates on this exciting technology.
