With that in mind, a patent recently received by Apple could help solve the technological issues the tech giant has faced working on this feature. Apple was having issues getting the infrared light, used to scan the user’s face and verify it, through the pixels under an iPhone’s display. The patent, awarded to Apple by the USPTOis called “Methods and Configurations for Improving the Performance of Sensors Under a Display.”
Apple’s plan is to remove part of each pixel affected called a subpixel. These subpixels display red, green, or blue light. Removing a portion of a subpixel array should allow the infrared light to get through the pixels under the screen. Even with the subpixels removed, the final image will remain the same as the removed subpixels align themselves with nearby subpixels of the same color.

The patent also notes that removing parts of the touch-sensitive mesh could improve the infrared pass-through. The pieces of the mesh removed would be too small to impact the responsiveness of the touch screen.
An under-display Face ID might not be ready until next year’s iPhone 18 Pro and iPhone 18 Pro Max. Or, it’s possible that the complex technology discussed in the patent is never used and Apple has to come up with another way to allow the components used in Face ID to be housed under the display. The patent awarded to Apple is US 12,201,004 and the date it was issued was January 14th, 2025. Seven different Apple employees are listed as the inventors.
