Advancements in iPhone Camera Technology: Under-Display Camera Development

Apple’s Push for an ‘All-Screen’ iPhone
Apple is taking strides towards achieving a truly “all-screen” appearance for its iconic iPhone. The company’s Korean suppliers are currently in the early stages of developing smartphone under-display cameras (UDC). This innovative technology, which sits beneath the display, aims to eliminate the visible camera hole in the panel when the camera is not in use.
Understanding Under-Display Cameras (UDC) and Challenges
The Unique Features of UDC
A UDC is distinct from a traditional front camera module, primarily because it delivers less light to the image sensor. This reduction in light is a consequence of the display area through which it passes before reaching the camera lens. Consequently, this journey can lead to a loss in image quality and brightness.
LG Innotek’s Solution: ‘Freeform Optic’ Multiple Lens System
To counteract this challenge, LG Innotek, a key player in this development, is working on a revolutionary “freeform optic” multiple lens system. This system is designed to mitigate optical aberrations, ensuring a reduction in image deterioration and an enhancement in peripheral image quality. Patents for this technology have been in the public domain since December of the previous year, and further innovations are anticipated as the development progresses.
The Role of LG Display in Under-Display Camera Development
Strategic Moves by LG Display
LG Display, an affiliate of LG Innotek within the LG Group, has also embarked on the development journey of Under-Display Cameras. The focus is on improving the light transmittance of UDC, with an ambitious goal of achieving 20% by 2023 and an even more impressive 40% post-2024. This aligns with Apple’s standards for optimal performance.
Challenges Faced: Apple’s Unmet Expectations
Despite strides in development, Apple reportedly received a sample of the UDC from an undisclosed vendor, deeming its performance unsatisfactory. This setback emphasizes the intricate challenges involved in perfecting under-screen camera technology.
Future Timeline: Integration into iPhones
Intermediate Step: Under-Panel Face ID in 2025
Before fully embracing perfected under-screen camera technology, Apple plans to integrate under-panel Face ID technology in its 2025 iPhone 17 Pro. This model is expected to retain a circular cutout for the front-facing camera, marking a transitional phase in Apple’s design evolution.
Anticipated Adoption in 2027: ‘Pro’ iPhone Models
According to respected analyst Ross Young from Display Supply Chain Consultants, Apple is projected to adopt Under-Display Cameras in its “Pro” iPhone models by 2027. This marks a significant shift in Apple’s premium lineup, phasing out the traditional front-facing camera cutout in favor of the sleek and seamless under-display camera technology.
