When the head-up display 100 works, external light is difficult to avoid entering the head-up display 100, the inner side walls of the first shell 110 and the second shell 120 are set as the light-shielding wall 150, the light-shielding wall 150 can absorb the external light irradiating the inner side walls of the first shell 110 and the second shell 120, and the phenomenon that the external light is reflected by the side walls of the first shell 110 and the second shell 120 to form stray light is avoided, and the stray light enters the reflector set 140 to be mixed with image information light to influence the image quality and further influence the display of the image information. In addition, the light-shielding wall 150 is disposed on the inner side walls of the first casing 110 and the second casing 120, and is formed by performing special processing on the inner side walls of the first casing 110 and the second casing 120, and the light-shielding wall 150 achieves the purpose of eliminating stray light of the light-shielding cover.

In order to enable the image information light to be incident on the first reflecting mirror 141 and incident on the second reflecting mirror 142 after being reflected by the first reflecting mirror 141, the first reflecting mirror 141 and the second reflecting mirror 142 should be opposite to each other and disposed at a position offset from each other, and a second predetermined included angle should be formed between the first reflecting mirror 141 and the second reflecting mirror 142.

The mirror surface of the first reflecting mirror 141 and the mirror surface of the second reflecting mirror 142 may be the same or different, and may be any one of a plane reflecting mirror, a spherical reflecting mirror, or a free-form surface reflecting mirror, for example, the first reflecting mirror 141 is a plane reflecting mirror, and the second reflecting mirror 142 is a concave reflecting mirror, because of the imaging rule of the concave reflecting mirror, in order to generate image information light via the imaging component 130, a vertical and enlarged virtual image can be formed on the front windshield of the automobile after the reflection of the mirror surface of the first reflecting mirror 141 and the mirror surface of the second reflecting mirror 142, and meanwhile, the volume of the head-up display 100 needs to be reduced as much as possible, the occupied space of the head-up display 100 in the automobile is saved, and the second reflecting mirror 142 is set as a concave reflecting mirror.

The arrangement of the first sub-housing 112 and the second sub-housing 113 can increase the first light passage, so that the distance between the imaging assembly 130 and the first reflecting mirror 141 can be increased, thereby reducing the occurrence probability of stray light. The blocking surface is used for blocking the opening, and the processing complexity of parts can be reduced. In addition, the arrangement of the first sub-housing 112 and the second sub-housing 113 can also prevent the internal light source from influencing the image information light, thereby improving the imaging effect.
