HoloFlex: A Flexible Light-Field Smartphone with a Microlens Array and a P-OLED Touchscreen
summary
A flexible light-field smartphone prototype combines a P-OLED 1080p display with a 3D‑printed microlens array of 16,640 microlenses on a 0.5 mm clear substrate to produce about 160 × 104 effective viewports by rendering 12‑pixel circular pinhole blocks; it preserves stereoscopy and motion parallax without glasses or head tracking, corrects ray directions for cylindrical bending, runs 16,640-view ray tracing in real time only for simple graphics on the phone GPU, and shows bend input yields ≈24% faster movement time than a touch Z slider.
