Under-panel cameras provide an intriguing way to maximize the display area for a mobile device. An under-panel camera images a scene via the openings in the display panel; hence, a captured photograph is noisy as well as endowed with a large diffractive blur as the display acts as an aperture on the lens. Unfortunately, the pattern of openings commonly found in current LED displays are not conducive to high-quality deblurring. This paper redesigns the layout of openings in the display to engineer a blur kernel that is robustly invertible in the presence of noise. We first provide a basic analysis using Fourier optics that indicates that the nature of the blur is critically affected by the periodicity of the display openings as well as the shape of the opening at each individual display pixel. Armed with this insight, we provide a suite of modifications to the pixel layout that promote the invertibility of the blur kernels. We evaluate the proposed layouts with photomasks placed in front of a cellphone camera, thereby emulating an under-panel camera. A key takeaway is that optimizing the display layout does indeed produce significant improvements.
