Abstract

The embodiment of the invention discloses a head-up display and an automobile, and belongs to the field of image display. According to the embodiment of the invention, the DLP device, the refraction reflector and the imaging diffusion film are packaged in the DLP packaging shell to obtain the DLP display module, and then the DLP packaging shell is connected with the curved surface reflector packaging shell packaged with the first curved surface reflector unit and the second curved surface reflector unit to obtain the head-up display. Through the modular design, the structure of the head-up display is simpler and more compact, and the assembly volume of the head-up display is effectively reduced.

Description

technical field [0001] The embodiments of the present application relate to the field of image display, and in particular, to a detection method for an automobile and a head-up display. Background technique [0002] The Head Up Display (HUD) installed on the car can project the vehicle condition information to the front windshield of the car during the driving process, so that the driver can check the vehicle condition information at any time without lowering his head, improving the driving safety. Based on this, more and more car manufacturers are beginning to install HUDs on their cars. In the HUD production process, in order to ensure the quality of the projected image of the vehicle condition information displayed on the front windshield of the car, the relative position between the various components included in the HUD is required to be high, resulting in a low pass rate of HUD products. [0003] In the related art, the HUD is obtained by fixing a plurality of compon...
