Abstract
AbstractAn ultra‐short throw pico‐projector module including a newly developed LED projection optical system is presented. The projection optic system features two right‐angled prisms and a convex aspheric mirror. We have achieved 10.7 inch projected image size at a display screen which is 115mm away from aspheric mirror. The maximum TV distortion for all fields at all distances is less than ±1%. When combined with virtual input devices, the ultra‐short throw pico‐projector will create a new market and contribute to more comfortable human life.
