Abstract: A projection screen includes a substrate with a first substrate surface. The first substrate surface includes a first region and a second region adjacent to the first region. Multiple first wire grid bodies extending in a first direction are provided in the first region. Multiple second wire grid bodies extending in the first direction are provided in the second region. Each first wire grid body includes a first contact surface connected to the substrate and a first surface, and a first angle is formed therebetween. The first angles gradually decrease in a direction from the first region to the second region. Each second wire grid body includes a second contact surface connected to the substrate and a third surface, and a third angle is formed therebetween. The third angles gradually increase in a direction from the first region to the second region.

Abstract: A wire grid structure and a manufacturing method therefor, and a projection screen are provided. The manufacturing method includes: extruding a molten mixed material body in a melt extruder to a casting roll to form a casting piece; patterning the casting piece by means of an impression roll to form a precursor having a preset wire grid structure pattern, where the precursor is wound on the impression roll and has a first dimension in a height direction; stretching the precursor by a first group of stretching rolls and a second group of stretching rolls in two opposite directions along a direction perpendicular to the height direction to form the wire grid structure, a preset distance being configured between the first group of stretching rolls and the second group of stretching rolls. The wire grid structure has a second dimension in the height direction that is greater than the second dimension.

Abstract: A projection screen and a processing method therefor, wherein the projection screen comprises, in sequence from the incident side of projection light, a diffusion layer, a microlens array and a substrate. The inner side of the substrate is provided with a Fresnel microstructure, and part of the surface of the Fresnel microstructure is provided with a reflecting layer while the remaining part of the surface is a light absorbing layer. The microlens array is used for focusing the projection light on the reflecting layer. The reflecting layer is used for reflecting projection light back to the field of view of viewers. Ambient light is mostly absorbed by the light absorbing layer. The settings of the structure and dimension of the microlens array enable the projection light to be only incident onto the reflecting layer of the Fresnel microstructure and the ambient light to be mostly absorbed by the light absorbing layer.

Abstract: A transparent projection screen and a manufacturing method. The transparent projection screen is for receiving projection light and transmitting ambient light and comprises a first substrate layer, a Fresnel structure layer, a surface diffusion layer, a nano metal plating layer, and a binding adhesive layer. The Fresnel structure layer is disposed on the first substrate layer and comprises a prism surface. The surface diffusion layer is disposed on a portion of the prism surface. The nano metal plating layer is disposed on the surface diffusion layer. The binding adhesive layer is disposed on the nano metal plating layer and fills and levels the prism surface. The projection light passes the first substrate layer and is incident on the prism surface and then reflected thereby. The ambient light passes the binding adhesive layer, the nano metal plating layer, the surface diffusion layer and the first substrate layer, and is emitted.

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.

Abstract: A total reflection screen comprises a light diffusion layer, a total reflection layer and a light absorption layer arranged sequentially from an incidence side of the projected light. The light absorption layer can absorb an incident light. The light diffusion layer is used for increasing a divergence angle of emergent light. The total reflection layer comprises a plurality of microstructure units that is rotationally symmetrical and extends continuously in a plane of the total reflection screen. Each of the microstructure units comprises a first material layer disposed at the side of the light diffusion layer and a second material layer disposed at the side of the light absorption layer. The interface between the first material layer and the second material layer is comprised of two intersecting planes, which are disposed in such a way that the projected light is subjected to total reflection continuously at the two intersecting planes.
