Abstract

An electronic device includes a display panel and an optical deflector. The display panel irradiates an original light group corresponding to an original image displayed by the display panel and having a first resolution. The optical deflector receives the original light group and emits at least two output light groups having different transmission directions within a visual persistence duration. The at least two output light groups form an output image having a second resolution greater than the first resolution.
