## Abstract

An integrated cluster and head-up display device for a vehicle includes a display device and a controller. The display device may have a display area including an area of cluster information and an area of head-up display (HUD) information. The controller is configured to control an operation of the display device.

## Claims

### Claim 1

An integrated cluster and head-up display device for a vehicle, comprising:
a display device having a display area including an area of cluster information and an area of head-up display (HUD) information;
a controller configured to control an operation of the display device;
a first optical mirror which reflects the HUD information to a windshield;
a second optical mirror which reflects the HUD information to the first optical mirror; and
a third optical mirror which displays virtual cluster information by reflecting the cluster information,
wherein, when the second optical mirror and the third optical mirror are moved on the display device by a motor, the second optical mirror reflects the HUD information and the third optical mirror reflects the cluster information, and
wherein the controller controls the display device to deactivate the HUD information and display only the cluster information.

### Claim 2 (depends on 1)

The integrated device of claim 1, wherein the controller adjusts a resolution of the cluster information area and a resolution of the HUD information area.

### Claim 3 (depends on 2)

The integrated device of claim 2, wherein the controller controls the display device to display the cluster information at a low resolution and display the HUD information at a high resolution.

### Claim 4 (depends on 2)

The integrated device of claim 2, wherein the controller adjusts a size of the cluster information area and a size of the HUD information area.

### Claim 5 (depends on 1)

The integrated device of claim 1, wherein the display device comprises a liquid crystal display (LCD) device.

### Claim 6

An integrated cluster and head-up display device for a vehicle, comprising:
a display device having a display area including an area of cluster information and an area of head-up display (HUD) information;
a controller configured to control an operation of the display device;
a first optical mirror which reflects the HUD information to a windshield;
a second optical mirror which reflects the HUD information to the first optical mirror; and
a third optical mirror which displays virtual cluster information by reflecting the cluster information,
wherein, when the second optical mirror and the third optical mirror are moved on the display device by a motor, the second optical mirror reflects the HUD information and the third optical mirror reflects the cluster information, and
wherein the controller controls the display device to deactivate the cluster information and display only the HUD information.
