Problems solved by technology

However, the image distance from the image generated by the current head-up display to the eyes of the driver is fixed, so when the driver is driving at high speed or low speed, if he wants to view the information generated by the head-up display, it takes time to focus his eyes At the image distance where the image is located, such an eye-focusing time delays the time for the user to pay attention to the road conditions in front of the car

Abstract

A head-up display including a display panel, a non-mechanical focusing lens, and a determining unit is provided. The display panel is configured to emit an image beam. The non-mechanical focusing lens is disposed on a transmission path of the image beam and generates an image of the image beam. The determining unit is electrically connected to the non-mechanical focusing lens and configured to adjust a focal length of the non-mechanical focusing lens according to a sensing signal, so as to change an image distance from the image to a user's eye.

Description

technical field [0001] The present invention relates to a display, and in particular to a head-up display. Background technique [0002] In today's society, in addition to the performance of vehicles, the requirements for vehicle interiors and safety equipment are also beginning to be emphasized. The assistance of these technological products (such as in-vehicle voice navigation system, voice collision warning system, etc.) has indeed improved the accident rate caused by the driver's long-term fatigue driving and inattention. But at the same time, non-voice information display devices are usually installed on the dashboard, and when the driver looks down, it is easy to affect driving safety. [0003] The vehicle head-up display (HUD) presents the information required by the driver in front of the driver, so that the driver does not need to be distracted to bow or turn his head, which can help driving safety. However, when the driver is driving a car, the distance at which ...
