There are a display unit and a vehicular display device. The display unit emits a display image including display light to be projected onto a projection target member provided in a vehicle. The display unit includes: a lens including a lens body and a first support portion protruding from an edge portion of the lens body; and a case that has a space configured to accommodate the first support portion and holds the lens by fitting the first support portion into the space.

A split exit pupil heads-up display (HUD) system and method. The HUD system architecture makes use of a split exit pupil design method that enables a modular HUD system and allows the HUD system viewing eye-box size to be tailored while reducing the overall volumetric aspects. A single HUD module utilizes a micro-pixel imager to generate a HUD virtual image with a given viewing eye-box size. When integrated together into a single HUD system, a multiplicity of such a HUD modules displaying the same image enables an integrated HUD system to have an eye-box size that equals the same multiple of the eye-box size of a single HUD module. The brightness of the integrated HUD system is maintained while the eye-box size becomes multiple size of the eye-box of a single module. The integrated HUD system can be comprised of multiplicity of single HUD modules to scale the eye-box size to match the intended application while maintaining system brightness.

A vehicle display device includes: an image display device; a hood part; a combiner disposed on an eye point side with respect to an upper display region; a housing part that houses a lower display region and has an opening; a reflection member that is disposed inside the housing part, is opposed to the combiner via the opening, and reflects display light of the lower display region toward the combiner; a motor that adjusts a position of a virtual image based on an image in the lower display region in an image vertical direction by rotating the reflection member; and a control unit that controls the image display device and the motor. The control unit is configured to be able to adjust, to a predetermined position determined in advance, a relative position of a virtual image with respect to the upper display region when viewed from the eye point.

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.

A head-up display apparatus for a motor vehicle is disclosed. The head-up display includes a housing part in which an image creation unit of the display apparatus is arranged, and an illumination device, by means of which light is applied to the image creation unit. The image creation unit is configured to provide an image which is projectable onto a light transmissive projection surface. A holding device is secured to the housing part in the region of the illumination device. The image creation unit is retained on the holding device.

A display control ECU includes an information acquisition section and a display control section. The information acquisition section acquires information relating to a peripheral target object that is present ahead of the vehicle and in a subject vehicle lane in which the vehicle is currently traveling, and information relating to an object requiring caution that is present outside of the subject vehicle lane and having implications for control during the autonomous driving. The display control section displays an image of the peripheral target object, regarding which information has been acquired by the information acquisition section on a heads-up display provided inside a cabin of the vehicle, and additionally displays on the heads-up display an image of the object requiring caution in a case in which information relating to the object requiring caution has been acquired by the information acquisition section.
