Abstract
Official abstract text for this publication.
A HUD apparatus includes a display device, a first mirror, a second mirror, a housing, a cover, an inner case, and a bezel with light-shielding wall. The bezel with light-shielding wall is attached to an upper end portion of the first mirror. The bezel with light-shielding wall shields any external light entering the housing from the opening portion and prevents the generation of any unexpected reflections on the windshield. Also, by attaching the first mirror to the bezel with light-shielding wall, the reflection range on the first mirror is suppressed to the minimum necessary, and the display light leaking out of the optical path for the virtual image display is not reflected by the first mirror such that it is possible to prevent the generation of any stray light.
First claim
Opening claim text (preview).
What is claimed is: 1 . A head-up display apparatus, comprising: a display device; a first mirror reflecting display light emitted from the display device; a second mirror reflecting the display light being reflected by the first mirror; and a housing accommodating the display device, the first mirror, and the second mirror, wherein the first mirror is a configuration to make the display light to be crossed in an up-down direction before reaching the second mirror, and a member having a light-shielding wall is attached to at least one of the first mirror or the second mirror. 2 . The head-up display apparatus according to claim 1 , wherein the member having the light-shielding wall is attached to an upper end portion of the first mirror. 3 . The head-up display apparatus according to claim 1 , further comprising an inner case accommodated in the housing, wherein the inner case is made of a light-shielding member and disposed on a position where the display light reflected from the first mirror to the second mirror is not shielded.
