Abstract

A head-up display including a light source module, a spatial light modulator, an imaging screen group and a control unit is provided. The light source module is configured to project a light beam. The spatial light modulator is configured to modulate the light beam as a first image and a second image and project respective image lights of the first and second images. The imaging screen group is configured to reflect the image lights of the first and second images to the visible range of the user, such that the user can view the first and second images. The control unit is coupled to the spatial light modulator to input at least two modulation signals to control the beam-splitting mechanism of the spatial light modulator.
