AI Technical Summary

Technical Problem

Traditional HUD systems lack blue light adjustment, which causes users to be exposed to high-intensity blue light when staring at the displayed images for a long time, increasing the risk of visual fatigue, affecting driving or flight safety, and failing to meet the diverse needs of different usage scenarios and user groups.

Method used

Design a head-up display that includes a control unit, a blue light adjustment unit, an image generation unit, and a light detection unit. The light detection unit obtains the ambient light intensity, and the control unit adjusts the operation of the blue light adjustment unit to adjust the blue light component in the light beam, thereby realizing the blue light adjustment function.

Benefits of technology

By reducing the intensity of harmful short-wave blue light through the blue light adjustment function, visual fatigue is reduced, visual comfort is improved, and the needs of different scenarios and user groups are met, thus achieving both safety and convenience for image displays.

Abstract

This application provides a head-up display and a mobile device, including: a control unit, a blue light adjustment unit, an image generation unit, and a light detection unit; the control unit is electrically connected to the light detection unit and the blue light adjustment unit, and the blue light adjustment unit is also electrically connected to the image generation unit; wherein, the image generation unit is configured to generate a light beam; the light detection unit is configured to acquire the light intensity of ambient light; the control unit is configured to control the blue light adjustment unit to operate based on the light intensity, so as to adjust the blue light contained in the light beam. By setting the blue light adjustment unit, the head-up display can adjust the blue light contained in the light beam emitted by the image generation unit based on the light intensity of ambient light, thus enabling the head-up display to have a blue light adjustment function.
