A Turning Point for Under-Display Camera Commercialization: A Close-Up Analysis of Apple’s 2026 Strategy (iPhone 18: IR Camera, Foldable: Selfie Camera… OTI Solutions Are Key)
Apple plans to apply under-display camera technology differently depending on the device type in its next-generation iPhone lineup, slated for release in 2026. According to industry sources, the iPhone 18 series will feature an under-display infrared (IR) camera, while the foldable iPhone, scheduled for release at the same time, will feature an under-display selfie camera. This is not a simple design change; it is a strategic decision that takes into account the structural characteristics and user experience of each device.
Bar-type iPhones require a polarizer to suppress external light reflection and improve outdoor readability. However, polarizers absorb both visible and infrared light, significantly reducing transmittance. This structural limitation could directly lead to poor image quality and consumer dissatisfaction if the front-facing selfie camera is placed under the display. In contrast, IR cameras only require a 940nm near-infrared wavelength, and their goal is not high-quality photos, but accurate security authentication. Therefore, the iPhone 18 series will incorporate an under-display IR camera to simultaneously implement a full-screen design and Face ID security features. This is the most reasonable approach, minimizing image quality concerns while enhancing design perfection.
The foldable iPhone is a different story. To ensure thickness and flexibility, the device adopts a structure that eliminates the polarizer, replacing it with a color correction film and phase compensation material. This relatively increases display transmittance, facilitating the application of an under-display selfie camera. While camera performance degradation remains, this can be sufficiently addressed through AI-based image correction technology and ISP improvements. Samsung Electronics has already incorporated an under-display camera into the Galaxy Z Fold series, and Apple plans to leverage the same structural advantages to incorporate an under-display selfie camera into its foldable iPhone.
A key technology in this process is the Cathode Patterning Material (CPM) from Canada’s OTI Lumionics. This technology prevents the deposition of metal cathodes in specific areas during the OLED manufacturing process, forming a transparent opening. This technology facilitates the stable operation of the under-display camera and IR sensor. This solution, which maintains screen quality while ensuring the transmittance required by the camera and sensor, has already been verified by major global panel manufacturers, and Apple plans to incorporate it into the iPhone 18 series and foldable iPhone.

UBI Research Executive Vice President Changwook Han emphasized, “Apple’s choice to use an under-display IR camera in the bar type and an under-display selfie camera in the foldable is the result of choosing an optimized solution for each product structure,” and “2026 will be a turning point when Apple commercializes under-display technology in earnest.”
