摘要： An image generation unit includes a display panel, a first illumination system, and a second illumination system. The display panel has a first and a second imaging regions adjacently arranged and located on the same plane. The first illumination system provides a first light beam incident on the first imaging region at a first incident angle. The first imaging region converts the first light beam into a first image beam. The second illumination system provides a second light beam incident on the second imaging region at a second incident angle. The second imaging region converts the second light beam into a second image beam. The optical paths of the first light beam and the second light beam do not intersect with each other. The first image beam and the second image beam leave the display panel at different light exit angles.

摘要： A head up display device includes an image generation unit, an imaging unit, an infrared light splitting element, and at least one infrared light detecting element. The infrared light splitting element is located on a transmission path of at least one ambient light beam, and configured to split an infrared light beam from the at least one ambient light beam. The at least one infrared light detecting element is located on a transmission path of the infrared light beam of the at least one ambient light beam, and configured to detect light intensity of the infrared light beam. When the at least one infrared light detecting element detects that the light intensity of the infrared light beam exceeds a predetermined threshold, the head up display device reduces light intensity of a portion of the at least one ambient light beam transmitted to the image generation unit.

摘要： A head up display including an image-light source, at least one reflector and a light modulation device is provided. The image-light source is configured to provide an image light. The at least one reflector is configured to transmit the image light to leave the head up display. On the transmission path of the image light, the light modulation device is disposed in the head up display. An ambient light enters the image-light source after passing through the light modulation device, and a light energy of the ambient light entering the image-light source is less than or equal to 25% of a light energy of the ambient light entering the head up display.
