<p>An electronic device based on a micro display technology, which comprises a projection optical unit (1), a concave-convex screen (2) for receiving light emitted by the projection optical unit, and optical components (31, 32) for imaging the light emitted by the projection optical unit (1) clearly on the concave-convex screen (2). In this way, images projected by the projection optical unit can be displayed on a flat screen as well as a concave-convex screen, making the imaging modes diversified.</p> |
