Problems solved by technology

The main source of strong light is reflected light. In a strong light environment, even if the light intensity is increased, the driver still cannot see the virtual image presented by the system.

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 vehicle window display system and method. The system includes polarized glasses and a projection system arranged inside the vehicle; the projection system includes a projector light source, a polarization beam splitter, left and right eye display chips, and left and Right eye projection lens. The polarizing beam splitter of the system polarizes the light emitted by the projector light source into two beams of polarized light beams perpendicular to each other, so that the two beams of polarized light beams are respectively irradiated on the left and right eye display chips. The eye image and the right eye image are projected by the left and right eye projection lenses, reflected by the window glass, and processed by polarized glasses to reach the human eye. This technical solution can realize the average attenuation of strong light reflection pollution by 50%, and the attenuation of external natural light by 50%, thus eliminating or reducing the problem of strong light pollution, and can not attenuate the polarization state light passing through the left and right eyes, while making the light passing through The light from the left and right eyes does not interfere with 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...
