Recent reports indicate that Apple is rethinking its display technology in preparation for the highly-anticipated iPhone Fold, focusing on minimizing the crease where the screen bends. This involves a significant shift from an on-cell touch sensor architecture to an in-cell design, which enhances durability and increases the device’s longevity.
According to Mark Gurman from Bloomberg, this ambitious aim to reduce the crease on the inner display involves a major technology shift. In the on-cell architecture, the touch sensor layer is placed just beneath the front glass or above the color filter polarizer for better sensitivity and simpler manufacturing. However, these layers can create air bubbles that promote crease formation over time.
In contrast, the in-cell architecture places the touch sensor below the color filter substrate but over the polarizer, minimizing air gaps and potentially reducing crease lines. This is not a new approach; Apple’s latest iPhone models already use this method to achieve smoother crease areas. The primary goal for Apple is to reduce visible creases on the front display, ensuring a seamless visual experience that aligns with its stringent quality standards.
The challenges include issues with the hinge mechanism and achieving a crease-free display. These factors could explain why Apple’s first foldable iPhone is launching years after Samsung and even Google. However, Apple’s extensive research in this category and its commitment to adhering to high-quality standards may position the device at the top of the market.
