Apple Secures Under-Display Face ID Patent: Solving Infrared Light Transmittance Challenges and Ushering in a New Era of Full-Screen Displays

Apple recently obtained a patent for under-display Face ID technology, successfully overcoming a long-standing challenge in under-display camera technology. This news has quickly garnered widespread attention from the tech industry and consumers alike. This breakthrough signifies a new milestone in the era of full-screen smartphones and points towards a new direction for the design and development of future smartphones.

Under-display camera technology has long been a pursuit of mobile phone manufacturers, promising the complete elimination of screen "notches" or "punch-holes," achieving a truly bezel-less display. However, realizing this technology hasn't been easy. The biggest challenge has been balancing screen display quality and the reliability of biometric functions.

The primary hurdle for under-display Face ID technology is infrared light transmittance. Face ID, a core biometric technology in Apple iPhones, relies on infrared light to scan and identify facial features. However, infrared light encounters significant obstacles when penetrating the display screen, resulting in extremely low transmittance. Placing the Face ID components directly under the screen would significantly reduce facial recognition speed and accuracy, potentially leading to recognition failures, severely impacting user experience and security. This low transmittance directly hindered the application and development of under-display Face ID technology.

To overcome this challenge, Apple's patented solution ingeniously leverages the pixel structure of OLED screens. It enhances infrared light transmittance by selectively removing some sub-pixels. OLED screens are composed of countless pixels, each consisting of multiple sub-pixels to represent different colors. Apple's patent doesn't simply remove entire pixels, but rather selectively removes adjacent sub-pixels of the same color. This creates small channels that allow infrared light to pass through the OLED panel and reach the Face ID components.

The brilliance of this technology lies in the fact that although some sub-pixels are removed, the difference is almost imperceptible to the naked eye. Apple employs advanced color mixing techniques, using neighboring sub-pixels to compensate for the missing ones, ensuring the integrity and consistency of the overall screen display. This precise color compensation maintains high-definition, detailed visual quality for the user.

Apple's successful patent is not just about solving a key problem in under-display Face ID technology; it showcases Apple's continued investment in technological innovation and its strong R&D capabilities. This breakthrough offers new ideas and inspiration for other mobile phone manufacturers. Many manufacturers have previously attempted various under-display camera technologies, but have faced challenges in imaging quality and recognition accuracy. Apple's new patent provides a feasible and effective solution to these problems, potentially driving technological advancements across the industry.

The mature application of this technology is expected to revolutionize smartphone design. Full-screen displays will transition from a concept to a reality. Manufacturers will be able to abandon "notch" and "punch-hole" designs, offering users a more immersive visual experience. Simultaneously, the widespread adoption of under-display Face ID technology will further enhance phone security, providing users with a more convenient and secure biometric experience.

Furthermore, the significance of Apple's patent extends beyond Face ID itself. It provides a reference and inspiration for the R&D of other under-display sensor technologies. For example, under-display fingerprint recognition and under-display heart rate sensors face similar transmittance challenges. Apple's solution can provide new approaches for these technologies, thereby driving upgrades and development across the mobile device industry chain.

However, this technology is not without its flaws. The patent description suggests Apple's solution may require specific design and optimization of the OLED screen's pixel structure. This could increase production costs and impact product pricing. Furthermore, this technology requires further testing and refinement to ensure its stability and reliability before widespread commercial application.

Despite this, Apple's under-display Face ID patent is still a landmark event. It marks a significant breakthrough in under-display camera technology, signaling a new development phase for full-screen smartphones. This technology will not only influence the design and development of future smartphones but will also have a profound impact on the entire mobile device industry chain. We can expect smartphones equipped with under-display Face ID technology to enter the market in the near future, offering users a more stunning visual experience and a more convenient and secure biometric experience. Apple's technological breakthrough has not only provided itself with a competitive advantage but has also injected new vitality into the industry, continuously driving progress in smartphone technology. We can look forward to more innovative technologies emerging in the future, resulting in even more exciting smartphone products.
