1. A display apparatus, comprising:
a light-emitting device including a plurality of light-emitting pixels, wherein the plurality of light-emitting pixels comprises a plurality of first light-emitting pixels and a plurality of second light-emitting pixels;
a micro-lens array including a plurality of lenses configured to project diffuse light rays emitted respectively from the plurality of first light-emitting pixels and the plurality of second light-emitting pixels to a first reaching position and a second reaching position located at desired different positions of a projection target object, respectively, wherein
the diffuse 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, the diffuse light rays emitted from the plurality of first light-emitting pixels to the first reaching position via the micro-lens array; and
project, at a second time instant, the diffuse light rays emitted from the plurality of second light-emitting pixels to the second reaching position via the micro-lens array, wherein
an amount of shift by the scanning mechanism from the plurality of first light-emitting pixels at the first time instant to the plurality of second light-emitting pixels at the second time instant corresponds to the pixel pitch of the plurality of light-emitting pixels.
