Patent ID: 8426795

Claim:
An image display apparatus, comprising: a screen, having a light incident surface; a reflection mirror, having a reflective surface facing the light incident surface of the screen and separated from the light incident surface of the screen by a space, and a boundary of the space defined by edges of the reflective surface and edges of the light incident surface; an adaptive optics, disposed on the boundary of the space defined by the edges of the reflective surface and the light incident surface and having a light incident side and a light exit side facing the reflective surface of the reflection mirror, said adaptive optics for adjusting an image size formed by a projecting light; and a projection unit, facing the light incident side of the adaptive optics and located outside the space, wherein the projection unit is capable of generating the projecting light to pass through the adaptive optics for adjusting the image size formed by the projecting light, and the projecting light comprises a plurality of light beams, wherein the light beams do not intersect with each other when passing through the adaptive optics and the light beams also do not intersect with each other before entering into the adaptive optics, and the light beams are projected to the reflective surface of the reflection mirror for being reflected to the light incident surface of the screen and passing the screen.
