Holographic windshield display and control method thereof

Abstract

A holographic windshield display system and a control method thereof are provided. The holographic windshield display system includes a windshield on which a holographic optical element (HOE) is laminated, a projection module to project an image onto the HOE, and a controller to control the projection module. The projection module includes at least one light source module including light sources having different central wavelengths, and a monitoring device to monitor changes in at least one characteristic among temperature and wavelength of the at least one light source module. The controller drives a light source whose central wavelength matches a central wavelength of a diffraction wavelength of the HOE among the light sources having different central wavelengths, based on the changed characteristic of at least one light source module.
