Problems solved by technology

As the incident angle increases, the ghosting problem of the head-up display projection imaging will become more and more serious, and it will become more and more difficult to solve
Current HUD systems, such as CN111433022A, CN111433023A and WO2021122848A1 cannot meet the needs of AR-HUD large-scale projection

Embodiment 1～3 and comparative example 1-3

[0116] The projection light source in the head-up display systems of Examples 1 to 3 and Comparative Examples 1 to 3 is a TFT-LCD projector with LED backlight, which also includes a plurality of reflecting mirrors. The display image that the user can observe is the clearest.

Embodiment 1

[0121] The soda lime silicate float glass with a thickness of 2.1 mm produced by Fuyao Group is used as the substrate. After cutting, edging, washing and drying, it enters the magnetron sputtering coating line for coating deposition. 45nm thick ZnSnOx film, 52nm thick TiOx film, 111nm thick SiO film are deposited on the whole surface (fourth surface) of the chip 2 film, SiN with a thickness of 5nm to form a transparent nano film, as the first reflective film and the second reflective film, after the film deposition is completed, the soda lime silicate float glass with a thickness of 2.1 mm produced by Fuyao Group is matched The PVB film is formed according to the high-temperature molding process of automobile glass, and a piece of PVB film with a thickness of 0.76 mm is sandwiched in the middle. Among them, the PVB film is colorless in the first head-up display area, and colored in the second head-up display area (the color PVB has 30cm wide colored ribbons), and then high-pre...

Embodiment 2

[0125] The soda lime silicate float glass with a thickness of 1.8 mm produced by Fuyao Group is used as the substrate. After cutting, edging, washing and drying, it enters the magnetron sputtering coating line for coating deposition. 32.5nm thick SiN film, 10nm thick AZO film, 13.8nm thick Ag film, 10nm thick AZO film, 77nm thick ZnSnOx film, 10nm thick AZO film, 6.2nm thick film are deposited on the whole surface (fourth surface) of the chip Ag film, 10nm thick AZO film, 34nm thick SiN film to form a transparent nano film, as the first reflective film and the second reflective film, after the film deposition is completed, the thickness of 2.1 mm of sodium produced by Fuyao Group Calcium silicate float glass is the matching sheet, and the second head-up display area on the matching sheet (the first surface) is coated with GP265 tempered glass pigment (produced by Tao Yise Glaze Co., Ltd.), the coating width is 30 cm, and the matching sheet High temperature sintering. It is fo...

Abstract

The present invention relates to the technical field of head-up display, in particular to a head-up display system. The head-up display system includes a laminated glass and a projection device, the laminated glass includes an outer glass plate, a thermoplastic intermediate layer and an inner glass plate, the laminated glass has a first head-up display area and a second head-up display area, and the projection device can generate a first polarized light and a second polarized light, the first polarized light contains at least 70% of the P-polarized light, the second polarized light contains at least 70% of the P-polarized light, and the first polarized light is incident on the first polarized light at an incident angle α of 45°-70° Head-up display area, the first head-up display area is used to display the first head-up display image, the second polarized light is incident on the second head-up display area at an incident angle β of 60°-85°, and the second head-up display area is used to display the second head-up display area. Heads-up display image. The head-up display system of the present invention can reflect light projected with a large incident angle, display a high-brightness image, and can suppress the ghosting problem.

Description

technical field [0001] The present invention relates to the technical field of head-up display, in particular to a head-up display system. Background technique [0002] Head Up Display (HUD) refers to a driver-centric, blind-operated, multi-function instrument panel. Its function is to project important driving information such as speed and navigation on the windshield in front of the driver, so that the driver can try not to lower his head or turn his head. Important driving information such as navigation improves driving safety. [0003] The applicable incident angle of conventional HUD is generally not more than 70°, but with the development of HUD technology, more technologies emerge, such as: Augmented Reality-Head-Up Display (AR-HUD), AR-HUD requires a larger range of incident angles , in order to project a larger display image size and meet the needs of a larger field of view (FOV). With the increase of the incident angle, the ghosting problem of HUD projection ima...
