Display apparatus

A display apparatus, comprising:

• a light-emitting device including a plurality of light-emitting pixels;
• a micro-lens array including a plurality of lenses configured to project light rays respectively emitted from a first light-emitting pixel group and a second light-emitting pixel group to a first reaching position and a second reaching position located at desired different positions of a projection target object, respectively, wherein
• the first light-emitting pixel group comprises a first set of light-emitting pixels selected from the plurality of light-emitting pixels,
• the second light-emitting pixel group comprises a second set of light-emitting pixels selected from the plurality of light-emitting pixels,
• the light rays are made incident on the plurality of lenses, and
• the plurality of lenses is at a pitch larger than a pixel pitch of the plurality of light-emitting pixels;
• and
• a scanning mechanism configured to:
• project, at a first time instant, light rays emitted from the first set of light-emitting pixels, that emits the light rays of identical information, to the first reaching position via the micro-lens array;
• and
• project, at a second time instant, the light rays emitted from the second set of light-emitting pixels, that emits the light rays of the identical information to the second reaching position via the micro-lens array, wherein
• an amount of shift by the scanning mechanism from the first set of light-emitting pixels at the first time instant to the second set of light-emitting pixels at the second time instant corresponds to the pixel pitch of the plurality of light-emitting pixels.
