| 发明名称 | Head-up display | ||
| 摘要 | A head-up display includes a display device and a combiner that has a rear surface brought into contact with an inner surface of a windshield of a vehicle, and reflects a display light rays emitted from the display device by a front surface of the combiner toward a driver in the vehicle. The front surface forms a first arc-shaped optical surface which receives and reflects the display light rays toward the driver so that the driver sees a first virtual image of the display light rays with a set magnification greater than 1 on the outside of the windshield. The rear surface forms a second arc-shaped optical surface which receives and reflects the display light ray toward the driver so that the driver sees a second virtual image which coincides with the first virtual image in terms of the size and position on an outside of the windshield. | ||

| 主权项 | 1. A head-up display comprising: a display device that emits display light rays; and a combiner that has a rear surface configured to be brought into contact with an inner surface of a windshield of a vehicle, and reflects the display light rays emitted from the display device by a front surface of the combiner toward a driver in the vehicle, the front surface being positioned outside of the windshield of the vehicle if the rear surface of the combiner is brought into contact with the inner surface of the windshield, wherein the front surface of the combiner forms a first arc-shaped optical surface which receives and reflects the display light rays emitted from the display device toward the driver so that the driver sees a first virtual image of the display light rays with a set magnification greater than 1 on the outside of the windshield, and the rear surface forms a second arc-shaped optical surface which receives and reflects the display light rays emitted from the display device toward the driver so that the driver sees a second virtual image which coincides with the first virtual image in terms of the size and position on an outside of the windshield. | ||
