AI Technical Summary

Technical Problem

Existing head-up displays are prone to screen burn-in due to focused glare when sunlight shines back, and reducing brightness is a solution that affects display clarity and fails to meet user needs.

Method used

By incorporating moving and rotating mechanisms within the head-up display, the display and reflective devices can be controlled to translate and rotate when sunlight shines back, altering the light path to prevent light spot focusing and ensuring the display does not lose brightness.

Benefits of technology

Protects display components when sunlight shines back, ensuring users can observe virtual images normally, avoiding reduced brightness, and improving user experience.

Abstract

The application provides a head-up display and a vehicle, comprising a display device, a reflecting device, a moving device and a rotating device; the reflecting device is arranged on the light-emitting side of the display device, and the rotating device is connected with the reflecting device; wherein the display device is configured to generate light; the reflecting device is configured to reflect the light; the moving device is configured to control the display device and the reflecting device to move in translation when the head-up display occurs sunlight backflow, and in the process of translation, the translation direction of the display device is the same as the translation direction of the reflecting device, and the translation distance of the display device is equal to the translation distance of the reflecting device; the rotating device is configured to control the reflecting device to rotate when the head-up display occurs sunlight backflow. The head-up display does not need to use the way of reducing brightness to protect the head-up display when sunlight backflow occurs, and the defects of using the way of reducing brightness are avoided.
