Abstract

The invention discloses a head-up display and a display control method. The head-up display comprises a display module and a reflecting layer, wherein the display module comprises a light modulation layer, the light modulation layer is arranged along a laser propagation direction and used for alternately modulating the propagation direction of laser so as to enable the laser to have two differentpropagation directions after passing through the light modulation layer and be projected to a reflective display; the reflective display is used for alternately generating a first image and a second image and projecting the first image and the second image to a reflective imaging layer; the reflective imaging layer is used for respectively performing reflective imaging on the first image and second image which are reflected by the reflective display; and the reflecting layer is used for reflecting the imaged first image and second image so as to be received by the human eyes, so that an observer can observe two independent images. According to the scheme provided by the embodiment of the invention, the light modulation layer divides the light source into two paths of light with different propagation directions and projects the two paths of light to the reflective display device so as to form two images, and the reflective imaging layer behind is matched to achieve double-layer display.

Description

technical field [0001] The present disclosure generally relates to the field of image display, and in particular relates to a head-up display and a display control method. Background technique [0002] In order to increase comfort and safety in modern vehicles, more and more vehicles are equipped with head-up displays (HUD). Usually, the head-up display uses a reflective imaging system to image the driving information displayed on a small display screen (the common size is 1.8 inches or 3.1 inches) into a virtual image suspended above the engine cover. Since the driver can observe important driving information without bowing his head or refocusing his eyes, the driver's sight can always be kept on the road, which improves driving safety. With the development, the head-up display that realizes double-layer display gradually appeared. The double-layer display refers to the virtual image suspended above the engine cover, including the state projection (near projection) display...
