Abstract

See full text

An image display apparatus and a vehicle provided with the image display apparatus. The image display apparatus includes a light source unit 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. In the image display apparatus, the two scanning lines have two different starting points for the two-dimensional scanning for a first time and the two-dimensional scanning for a second time, respectively.
