When the distance indicated by distance information received by a Bluetooth module (31) is less than a predetermined first reference distance (KY1), a guidance image (33) including a distance image (33a) and a direction image (33b) is generated, and this guidance image (33) is displayed on a combiner (26) of a helmet (20). By stopping the display of the distance image (33a) of the guidance image (33) and continuing to display the direction image (33b) from when the distance indicated by the distance information becomes less than a second reference distance (KY2) shorter than the first reference distance (KY1) to when the guidance point is reached, the driver's attention is focused on the direction image (33b), so that a mistake in the direction of travel at the guidance point can be prevented.

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.

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.
