A head-up display device operated in a vehicle comprises: a first image source disposed under the windshield of the vehicle, which emits a first polarized image light having a first polarization; a light path combining component in front of the first image source, which is for that the first polarized image light firstly goes to the light path combining component and only lets the first polarized image light be through and then the image light goes to the windshield, part of the image light is reflected by the windshield to a driver's eyes; and a second image source inside the vehicle, which emits a second polarized image light having a second polarization and then the image light directly goes to or reflects at least one time to the combining component, continuously to the windshield, and the second polarized image light is partially reflected by the windshield to the eyes. |

1. A head-up display device that is operated in a vehicle comprising:
a first image source, which is disposed under the windshield of the vehicle, the first image source emitting a first polarized image light having a first polarization; a light path combining component, which is in front of the first image source for that the first polarized image light firstly goes to the light path combining component after the first polarized image light is emitted by the first image source, the light path combining component only letting the first polarized image light be through, the first polarized image light then going to the windshield, thus part of the first polarized image light being reflected by the windshield to the eyes of a driver; and a second image source, which is inside the vehicle, the second image source emitting a second polarized image light having a second polarization, the second polarized image light directly going to or reflecting at least one time to the light path combining component after the second polarized image light is emitted by the second image source, the light path combining component thus reflecting the second polarized image light to the windshield, and the second polarized image light being partially reflected by the windshield to the eyes of the driver, with the first polarized image light going to the eyes of the driver, a second light path of the second image source to the eyes of the driver being longer than a first light path of the first image source to the eyes of the driver since the second polarized image light travels longer distance before hitting on the windshield. |
