Abstract

The invention relates to a laser projection display technique, and provides a head-up display system based on a laser light source. The head-up display system comprises a laser light source component, a light source control unit, a light intensity sensor, a display chip, a display chip control unit, a system control unit and a transparent screen, wherein the transparent screen is made of a transparent medium doped with at least three nano grains of different particle sizes; the nano grain of each particle size has a fixed resonance rayleigh scattering wavelength; the wavelengths correspond to the lighting wavelengths of the laser light source one to one; each kind of laser can form resonance rayleigh scattering on the screen, so as to form practical images. The head-up display system has the characteristics of wide visible range, simple optical design, vivid color and the like, the optical energy utilization rate of the light source is high.

Description

technical field [0001] The invention relates to laser projection display technology, in particular to a head-up display system based on a laser light source. Background technique [0002] Vehicle head-up display system (Head-Up Display, HUD), also known as head-up display system, is a display system displayed on the front windshield of the car, used to display car speed, speed, fuel consumption and navigation information, etc., the driver does not need to You can observe a lot of vehicle information by looking down, avoiding potential traffic safety hazards that may exist when the driver looks down at the dashboard information. At present, HUD is mostly configured in the interior of high-end cars. [0003] A common HUD system coats or attaches a film with high surface reflectivity on the inner surface of the front windshield of the car to reflect the light projected by the projection system under the glass. The image formed by this type of system is a virtual image , gener...
