The head-up display system includes a plurality of light sources arranged according to a predetermined rule; a micro-lens array including a plurality of micro-lenses, wherein each micro-lens corresponds to one or more light sources and adjusts directions of chief light of light emitted by the one or more light sources corresponding thereto, and the micro-lens array converges chief light of light emitted by the plurality of light sources so that chief light of light after being exited from the micro-lens array is directed to a predetermined range; and a reflector device for displaying at a side, away from the light sources, of the micro-lens array, and configured to emit light to an observation region.

Abstract: A display apparatus, a head-up display and a motor vehicle are provided. The display apparatus includes a projector device, a reflector structure and a light beam diffuser structure. Light emitted from the projector device passes through the light beam diffuser structure, is reflected by the reflector structure, and then reaches a first predetermined region; the light beam diffuser structure is configured to diffuse a light beam passing through the light beam diffuser structure; the reflector structure is configured to reflect the light emitted from the projector device and the light reflected by the plurality of sub-reflector structures reaches a second predetermined region within the first predetermined region if the light beam diffuser structure is removed from an optical path from the projector device to the first predetermined region, and an area of the second predetermined region is smaller than an area of the first predetermined region.

Abstract: Disclosed are a head-up display device and a motor vehicle. The head-up display device includes an image source, a transflective device and a light control device. The image source is configured to emit light for forming an image. The transflective device is configured to reflect light that is incident on the transflective device and allow the light that is incident on the transflective device to be transmitted. The light control device includes a retroreflection element and a dispersion element arranged above the retroreflection element; the retroreflection element is configured to reflect the light that is incident on the retroreflection element in a direction opposite the incident direction of the light that is incident on the retroreflection element; and the dispersion element is configured to diffuse the light that is incident on the dispersion element.

Abstract: The embodiments disclosed in this application describe a displaying system, a displaying method, and a head-up display. The heads-up displaying system includes a display window including a transflective film, an image source emitting light incident on the imaging window, and the light emitted by the image source before reaching the transflective film only comprising s-polarized light. The transflective film is configured to directly reflect a first portion of the s-polarized light emitted from the image source. The transparent substrate reflects a second portion of the s-polarized light, and transmits a third portion of the s-polarized light to the air, the first portion of the s-polarized light, the second portion of the s-polarized light and the third portion of the s-polarized light are all s-polarized light.

Abstract: The embodiments disclosed in this application describe a displaying system, a displaying method, and a head-up display. The displaying system includes a display window including a transflective film, an image source for emitting s-polarized light incident on the transflective film, where the transflective film has an average reflectivity more than 50% for the s-polarized light, and where the imaging window is further used to transmit ambient light. The embodiments disclosed herein can reduce the demand on the brightness of the image source, can eliminate ghost image, obtain better visual effect, and reduce cost.

Abstract: A system for imaging in the air including an image source, a transflector, and an retroreflective element. Light rays emitted by the image source are reflected by the transflector to irradiate on the retroreflective element, and are subjected to reflection on the retroreflective element, before being emitted along an original incident path in an opposite direction and being transmitted through the transflector to form a real image. By means of the present system, it is possible to directly present images in the air, even in vacuum, without the aid of any medium.
