## Abstract

Disclosed is a head-up display device. The head-up display device includes: a host (1), configured to send an image signal to a display device (2); a display device (2) provided at one side of the host (1), configured to display the image signal; a curved semi-transparent reflecting screen (3) provided in a position opposite to the display device (2), configured to receive an image displayed by the display device (2), and display the image on the other side of the semi-transparent reflecting screen (3) at one side of the host (1), wherein the semi-transparent reflecting screen (3) is further configured to display the image after ghost is removed; a voice interaction unit (20) pre-configured in the host (1), and a driver detection device (12) mounted in the host (1). The head-up display device supports voice interaction throughout a process, driver real-time monitoring, and advance warning, and has good display effect.

## Claims

### Claim 1

A head-up display device, comprising: a host, configured to send an image signal to a display device; the display device provided at one side of the host, configured to display the image signal; and a curved semi-transparent reflecting screen provided in a position opposite to the display device, configured to receive an image displayed by the display device, and display the image on the other side of the semi-transparent reflecting screen at one side of the host, wherein the semi-transparent reflecting screen is further configured to display the image after ghost is removed, wherein the display device is a laser projector, configured to project the image through laser beams; and a micro-lens array is provided between the curved semi-transparent reflecting screen and the laser projector, and configured to modulate the display of the laser beams on the curved semi-transparent reflecting screen.

### Claim 2 (depends on 1)

The head-up display device according to claim 1, wherein the display device is a flexible display screen, configured to change the image projected onto the curved semi-transparent reflecting screen by adjusting a shape of the flexible display screen, and correct image distortion in the display device.

### Claim 3 (depends on 2)

The head-up display device according to claim 2, wherein the host is provided with a base, a rotating locking platform is mounted on the base, and the rotating locking platform is configured to be locked on a slide rail on the base, and adjust a position of the image on the curved semi-transparent reflecting screen via a placement angle of the host.

### Claim 4 (depends on 1)

The head-up display device according to claim 1, wherein the ghost is removed from the image after following treatments are performed for the semi-transparent reflecting screen: molding the semi-transparent reflecting screen, and surface hardening both a concave surface and a convex surface of the semi-transparent reflecting screen; providing a semi-transparent mirror film to the concave surface; providing an Anti-reflection film to the convex surface; additionally providing an Anti fingerprint film to the concave surface and/or the convex surface; and finally performing all-around cutting for the semi-transparent reflecting screen.

### Claim 5 (depends on 4)

The head-up display device according to claim 4, wherein the host is provided with a base, a rotating locking platform is mounted on the base, and the rotating locking platform is configured to be locked on a slide rail on the base, and adjust a position of the image on the curved semi-transparent reflecting screen via a placement angle of the host.

### Claim 6 (depends on 1)

The head-up display device according to claim 1, wherein the host is provided with a base, a rotating locking platform is mounted on the base, and the rotating locking platform is configured to be locked on a slide rail on the base, and adjust a position of the image on the curved semi-transparent reflecting screen via a placement angle of the host.

### Claim 7

A head-up display device, comprising: a host, configured to send an image signal to a display device; the display device provided at one side of the host, configured to display the image signal; a curved semi-transparent reflecting screen provided in a position opposite to the display device, configured to receive an image displayed by the display device, and display the image on the other side of the semi-transparent reflecting screen at one side of the host, wherein the display device is a laser projector, configured to project the image through laser beams; and a micro-lens array is provided between the curved semi-transparent reflecting screen and the laser projector, and configured to modulate the display of the laser beams on the curved semi-transparent reflecting screen; and a driver detection device mounted in the host, configured to determine face state information of a driver according to face information, wherein the state information at least comprises emotional state information on distraction, fatigue, and road rage, and monitor and warn fatigue of the driver according to the face state information, real-time environment information, and real-time vehicle traveling speed.
