## Abstract

An electronic device includes an imaging light assembly including a display panel, a circuit board, a light source, and a light cover. The light source is mounted and electrically coupled to the circuit board. The light cover is mounted to a rear surface of the display panel and covers the light source. The light source emits light to the light cover. The light cover includes at least one projection lens located between the light cover and the display panel. The at least one projection lens focuses the light emitted by the light source and projects the focused light to the display panel. The focused light projected to the display panel projects an image of a design of the projection lens.
