HEAD-UP DISPLAY DEVICE

摘要

Provided is a head-up display apparatus that projects a display image, which is formed on a display surface, onto a projection surface of a movable body to display a virtual image viewable from a cabin of the movable body. The head-up display apparatus includes a display with pixels arranged along the display surface, a light source, and a diffusion plate for diffusing the light coming from the light source and emits the diffused light toward the display. The diffusion plate has through-holes in a thickness direction. In a specific direction on the display surface, an inner dimension of the through-hole is smaller than a pixel pitch of the pixels.

主权项

1. A head-up display apparatus that projects a display image, which is formed on a display surface, onto a projection surface of a movable body to display a virtual image viewable from an inside of a cabin of the movable body, the head-up display apparatus comprising:
a display that includes a plurality of pixels arranged along the display surface and controls the pixels to form the display image on the display surface; a light source that radiates light; and a diffusion plate that diffuses the light coming from the light source and emits the diffused light toward the display; wherein: the diffusion plate has a plurality of through-holes that penetrate the diffusion plate in a thickness direction of the diffusion plate; and in a specific direction on the display surface, an inner dimension of the through-hole is smaller than a pixel pitch of the pixels.
