Information display system of automobile glass and imaging method thereof

Abstract

The invention discloses an information display system of automobile glass, comprising a polarized light scatter imaging film adhered to the automobile glass, an optical projection system and an information collecting system. The optical projection system comprises a signal conversion module, an optical engine, an optical conversion module and a projection device, wherein the signal conversion module is used for converting the information into an electric signal, the optical engine is used for emitting light beams according to the electric signal, the optical conversion module is used for polarizing light beams into the polarized light, and the projection module is used for projecting the polarized light on the polarized light scatter imaging film; a liquid crystal reflecting device based on an LCOS chip is adopted for the optical conversion module. The invention has no influence from the aperture ratio so as to greatly improve the utilization of light source; a polarized light scatter theory of the polarized light scatter imaging film is utilized to image thereon without the limitation of viewing angles, double images, light halo or light interference from the inner part or the outer part of an automobile, so that the line of sight of the road condition in front can be seen semi-transparently. The technology of the invention can be widely used for various automobiles, ships, space flights and the like.

Description

technical field [0001] The invention relates to an automobile accessory device, in particular to a video imaging method and equipment for displaying automobile information. Background technique [0002] The existing technologies are mainly divided into several categories: the first category is to use the front glass surface of the car as a reflective surface to reflect the plane graphic information of the flat display device to the driver's eyes; Install an optical reflective element on the glass, and then use the graphic information formed by the transmissive optical element and the optical focusing element to project onto the optical reflective element installed on the front windshield of the car, until it is reflected to the driver's A display device in the eye. The third type is when producing the front windshield glass of automobiles, it is composed of two layers of glass, and a liquid crystal display composed of liquid crystal material is laid in the interlayer to dis...

AI Technical Summary

Problems solved by technology

[0009] The invention provides an automobile glass information display system and its imaging method. The polarized light imaging film is pasted on the automobile glass, which not only enables the driver to know the information in time, but also does not block the driver's line of sight or distract the driver. attention, ensure driving safety, and solve the technical problems of inconvenient driver observation or relatively high cost in existing technical information display systems
