Abstract: A head-up display unit with a picture generating unit for creating an image to be displayed as a virtual image to a viewer and an optical unit for projecting the image to be displayed towards an eyebox is disclosed. The picture generating unit comprises a liquid crystal layer, a front polarizer, a back polarizer and a reflective polarizer. The reflective polarizer is arranged upstream the front polarizer and downstream the liquid crystal layer.

Abstract: The invention is directed to a head-up display 2 having a light source 231, a diffuser 232,235,236, a transmissive display 3, a mirror element 251 and a transmissive screen 21. According to the invention the head-up display 2 is further provided with a contrast enhancer display 4 that is arranged adjacent to the transmissive display 3.

Abstract: A head-up display has an image generator, an optical system, a transmissive screen and a transparency mask. The transparency mask is arranged close to a display of the image generator. A mask pixel map is applied to the processed image to get a masked image.

Abstract: A layered glass assembly for optical light beam projection with three-dimensional depth perception for a vehicle includes: a display surface glass having a first refractive index and being configured to refract a first section of a light beam at a first interface; a first transition structure configured to refract a second section of the light beam at a second interface; a filler structure having a second refractive index and being configured to refract a third section of the light beam at a third interface; a second transition structure configured to refract a fourth section of the light beam at a fourth interface; and a front glass having a third refractive index and being configured to project the refracted light beam so as to generate the three-dimensional depth perception.

Abstract: A head-up display system for display on a windowpane includes: an image-generating display device configured to generate an image; and an optical system configured to deflect the generated image onto the windowpane. The image-generating display device is an electronic paper display device, the electronic paper display device including a curved image-generating surface having a curvature, the curvature of the image-generating surface being adjustable to adjust the curvature of the image-generating surface so as to compensate for image distortion occurring due to a curvature of the windowpane.
