Problems solved by technology
However, these existing technologies all use black ink or black film in the structure of the projection screen, so they will absorb part of the light and reduce the brightness of the emitted light
[0009] In summary, some of the above-mentioned prior art cannot be used in head-up displays or optical head-mounted displays, or the brightness of emitted light is reduced due to the use of black materials in the structural layer, and most of them cannot be flexibly combined with another non-planar transparent substrate.

Embodiment Construction
[0058] This disclosure is the best mode currently available for carrying out the invention. The invention is described herein with reference to various embodiments and drawings. These disclosures are intended to illustrate the main principles of the invention and are not intended to be limiting. Those skilled in the art should understand that various changes and improvements can be made within the scope of the spirit of the present invention. The scope of the present invention should be defined by the claims.
[0059] The formation of multiple microlens structures in this embodiment is to first use a laser engraving machine to engrave a copper plate to form a template with multiple regular hexagonal grooves with a side length of 60 μm, a frame thickness of 20 μm, and a depth of 35 μm. Then, the UV cross-linking curable resin is coated on the transparent base material by using a coating machine, wherein the thickness of the transparent base material is 50 μm, and the coating ...

The invention relates to a penetrable and reflectible optical projection film. The penetrable and reflectible optical projection film comprises a transparent substrate, a penetrable and reflectible layer, a plurality of micro lenses and pressing adhesive glue; the transparent substrate is provided with a first surface and a second surface opposite to the first surface; the penetrable and reflectible layer is arranged on the first surface; visible light can be partially reflected by and partially transmitted through the penetrable and reflectible layer; and the plurality of micro lenses are opposite to the transparent substrate and are located on the surface of the penetrable and reflectible layer. The optical projection film can be flexibly adhered to another plane or non-plane transparent substrate, so that an optical projection screen which can be penetrated by and reflect light can be formed. The optical projection film provided by the invention cannot only be applied to a head-up display or a head-mounted display, and can also reduce the proportion of light which is absorbed so as to enhance the brightness of emitted light.
Description
technical field [0001] The present invention relates to projection imaging components, especially a projection film that can see through, reflect and stick, which can be flexibly pasted on glass to form a projection screen (projection screen), which can be applied to head-up displays (HeadUpDisplay, HUD) or The Optical Head-Mounted Display (OHMD) combines the external scene and the information to be displayed on the projection screen into the same visual image. Background technique [0002] Traditionally, projection imaging can be divided into two categories: 1. Non-see-through projection screens, such as those used in cinemas, meeting rooms and home theaters; 2. See-through projection screens, such as coating on glass substrates, such as those used in rear projection TVs ( Rear-projection television). [0003] The non-see-through projection screen is formed by adding plastic resin or scattering inorganic particles to an opaque substrate to form an optical scattering struct...
