Abstract: Provided are an electronic device and/or a controlling method thereof. The electronic device may include a projection part; a memory storing at least one instruction; and at least one processor. The projection part may include a split prism for transmitting a part of light emitted from a light source in a front direction and reflecting a remaining part of light on at least one inclined surface in a lateral direction. The processor may be configured to convert an image corresponding to a received signal into a multi-sided image to be projected to a plurality of projection surfaces, and control the projection part to project the converted multi-sided image to the plurality of projection surfaces through the split prism.
