Embodiment Construction

[0036] In order to make the object, technical solution and advantages of the present invention clearer, the implementation manner of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0037] figure 2 A structural block diagram of a vehicle window display system provided by an embodiment of the present invention, the system includes polarized glasses 21, and a projection system 22 arranged inside the vehicle; the projection system 22 includes a projector light source 221, a polarization beam splitter 222, left and right eye Display chip 223 and left and right eye projection lenses 224 .

[0038] It should be noted that, for myopic or hyperopic people who need to wear glasses, the polarized lenses of the polarized glasses 21 in the embodiment of the present invention can be fixed on their glasses. The embodiment of the present invention does not specifically limit the assembly form of the polarized glasses 21. As lo...

Abstract

The invention discloses a head-up display system and method. The head-up display system comprises a pair of polarized glasses and a projection system arranged in a car, wherein the projection system comprises a projector light source, a polarizing beam splitter, left and right eye display chips, and left and right projection lenses; light rays emitted from the projector light source are polarized into two beams of light rays in a polarization state, which are perpendicular to each other, through the polarizing beam splitter of the system, the two beams of light rays in the polarization state respectively irradiate the left and right eye display chips, and a left eye image of the left eye display chip and a right eye image of the right eye display chip are projected through the left and right projection lenses, reflected by car window glass and processed through the polarized glasses, and finally reach human eyes. Due to the adoption the technical scheme, hard light reflection pollution is attenuated by 50% averagely, and external natural light is attenuated by 50%, therefore, the problem of hard light pollution is eliminated or reduced, the light rays being in polarization state and penetrating through left and right eyes are not attenuated, and light rays penetrating through left and right eyes do not interfere each other.

Description

technical field [0001] The invention relates to the field of optical technology, in particular to a vehicle window display system and method. Background technique [0002] The car window display (Head Up Display, HUD, also known as head-up display) system is a high-tech vehicle system. Its function is to project images into human eyes, and the driver can see the virtual dashboard, Images such as the GPS display screen appear outside the car window, allowing the driver to focus more and drive more conveniently. [0003] figure 1 It is the schematic diagram of the car window display system. The projection system projects the image in its display chip onto the car window glass. The image is reflected by the car window glass into the human eye, and the image of the vehicle information such as the instrument panel is formed in the human eye. [0004] A very serious defect of the vehicle window display system in the prior art is that it is interfered by strong external light. T...
