Abstract

The present invention relates to a display device and a vehicle including the same. The display device comprises a display array generating device and a first lens layer. The display array generatingdevice is configured to provide a plurality of beams of collimated light rays which are parallel to each other and spaced from each other; the first lens layer is arranged on the light emitting side of the display array generating device, comprises a plurality of first micro lenses arranged in an array, and is configured to receive the plurality of beams of collimated light rays; and the pluralityof beams of collimated light rays correspond to the plurality of first micro lenses to respectively realize a plurality of scanning images. The display device can be applied to a head-up display system.

Description

technical field [0001] Embodiments of the present disclosure relate to a display device and a vehicle. Background technique [0002] Head-up Display (HUD for short) is a vehicle-mounted head-up display system that can project and display vehicle status information such as vehicle speed, fuel level, navigation, and danger warnings on the windshield in front of the driver. This allows the driver to obtain relevant information such as vehicle speed and fuel level without deviating from the road ahead. [0003] At present, the vehicle-mounted head-up display system is usually a catadioptric optical system (that is, a system including refractive optical elements and reflective optical elements). However, with a large exit pupil distance (that is, the distance between the outermost optical surface on the light-emitting side of the vehicle-mounted head-up display system and the observation surface is large), a large viewing window (that is, the size of the observation area on the ...
