  • Patent number: 11002887
    Abstract: An image display apparatus includes: a light source to emit light; a lens array including a plurality of lenses arranged therein; and an image forming device to form an image with the emitted light on the lens array. The light corresponding to the formed image is transmitted from the lens array to be reflected by a reflective surface to visualize the formed image into a virtual image. At least two of the plurality of lenses of the lens array have curvatures different from each other.

  • Patent number: 10573213
    Abstract: An image display apparatus and a vehicle provided with the image display apparatus. The image display apparatus includes a light source to emit a laser beam, an optical deflector to deflect the laser beam two-dimensionally, and an intermediate image generator to perform two-dimensional scanning twice in a main scanning direction and a sub-scanning direction with the laser beam deflected by the optical deflector to generate an intermediate image of one frame, where the laser beam deflected by the optical deflector draws two scanning lines. In the image display apparatus, the two scanning lines have two different phases for the two-dimensional scanning for a first time and the two-dimensional scanning for a second time, respectively.
