Abstract: An optical film and an optical imaging system are provided. The optical film includes a first lens layer, a first deflection layer, a reflection layer, a second deflection layer, and a second lens layer. The second lens layer is attached to a windshield. The reflection layer is configured to reflect an image light beam to form a first reflected light beam and the first lens layer and the first deflection layer are configured to amplify and/or deflect the first reflected light beam, to guide the first reflected light beam to a field-of-view direction. The second lens layer and the second deflection layer are configured to amplify and/or deflect a second reflected light beam, to guide the second reflected light beam to a first direction. The second reflected light beam is formed by that the windshield reflects the image light beam. The field-of-view direction is different from the first direction.

Abstract: Provided is a projection screen, the taper angles of a plurality of triangular pyramid units arranged in an array are designed to gradually change according to a predetermined relationship, so that the image light emitted from the projector is reflected by a microstructure layer with a triangular pyramid unit and then converges to a range centered on the human eye, which reduces the difference in brightness at different viewing positions, so as to ensure that the projection screen has high brightness uniformity and high gain.

Abstract: A light source system and a projection apparatus are provided. The light source system includes a first light source, a second light source including a second blue laser light source, a wavelength conversion element configured to convert second blue laser light into excited light, and a controller. The first light source includes a first blue laser light source configured to emit first blue laser light, a red laser light source configured to emit red laser light, and a green laser light source configured to emit green laser light. The controller controls the first and second blue laser light sources, the red laser light source, and the green laser light source to combine the first blue laser light, the red laser light, and the green laser light to form light source light, or to combine the first blue laser light and the excited light to form the light source light.

Abstract: A head-up display screen, a head-up display assembly, and a vehicle are provided. The head-up display screen is attached to an inner side of an attachment surface of a windshield and configured to reflect image light emitted towards the windshield. The head-up display screen includes a functional layer, a reflective layer, and a protective layer that are sequentially arranged in a direction from the windshield to a driving position. The functional layer includes prism microstructures protruding from the inner side of the attachment surface of the windshield. The reflective layer is at least attached to lower inclined surfaces of the prism microstructures and is configured to reflect the image light towards the driving position. The protective layer covers the reflective layer and the functional layer.
