preparation example Construction

[0053] In order to achieve the above purpose, the present application also provides a method for preparing a high-definition transparent projection film 1, the preparation method is applied to the above-mentioned high-definition transparent projection film 1, including the following steps: S1, preparing the first microstructure layer 03, prepare the first base layer 04 in advance, the first base layer 04 has the lower surface of the first base layer and the upper surface of the first base layer opposite to the lower surface of the first base layer, and place the upper surface of the first base layer on a surface with a microstructure Under the first template, a first optically transparent resin is placed between the first base layer 04 and the first template, the first optically transparent resin will conform to the surface microstructure of the first template to form a film, and then solidify , to obtain the first microstructure layer 03, the first microstructure layer 03 has ...

Embodiment 1

[0061] Such as figure 1 As shown, a high-definition transparent projection film 1 of an embodiment is provided, and the high-definition transparent projection film 1 includes a first base layer 04, a first microstructure layer 03, a display bearing layer 02, a refractive index matching layer 01, and a functional layer 05 and protection layer 06.

[0062] The preparation process of the high-definition transparent projection film of the present embodiment is as follows:

[0063] Firstly, using a template with any random shape or a predetermined surface microstructure of certain patterns, a base film is placed under it, and the base film is the first base layer 04, and the first base layer 04 has a first sub-base layer. surface and the upper surface of the first base layer opposite to the lower surface of the first base layer, both the lower surface of the first base layer and the upper surface of the first base layer are flat surfaces; the first optically transparent resin is p...

Embodiment 2

[0069] Such as figure 2 As shown, a high-definition transparent projection film 1 of another embodiment is provided, and the high-definition transparent projection film 1 includes a first base layer 04, a first microstructure layer 03, a display bearing layer 02, a refractive index matching layer 01, and a functional layer 05. Composite layer 07 and second base layer 08.

[0070] The preparation process of the high-definition transparent projection film of the present embodiment is as follows:

[0071] The preparation method of the first base layer 04 , the first microstructure layer 03 , the display bearing layer 02 , and the refractive index matching layer 01 in the high-definition transparent projection film 1 is as described in the above-mentioned embodiment 1.

[0072] The difference between Embodiment 2 and Embodiment 1 lies in the preparation of the functional layer 05. In this embodiment, a second base layer 08 is added. The second base layer 08 has an upper surface ...

Abstract

The invention relates to a high-definition transparent projection film, a preparation method and a projection system applying the high-definition transparent projection film. The high-definition transparent projection film comprises a first base layer, a first microstructure layer located on the upper surface of the first base layer, a display bearing layer located on a preset first surface microstructural surface of the uneven first microstructure layer, a refractive index matching layer located on the display bearing layer, and a functional layer located on the backlight side of the display bearing layer, wherein the functional layer is used for blocking background light and / or reflecting part of incident light penetrating through the display bearing layer. The functional layer is arranged to reduce the brightness of light on the backlight side of the display bearing layer or reflect part of incident light penetrating through the display bearing layer to form secondary imaging, so that the imaging definition of the transparent projection screen is improved, the overall haze is kept unchanged while the projection brightness is increased, and the transparent projection film can be used under the high-brightness ambient light condition.

Description

technical field [0001] The invention relates to the field of projection technology, in particular to a high-definition transparent projection film, a preparation method and a projection system using the same. Background technique [0002] Transparent display is more and more favored by people because it integrates transparency and imaging, and can see the real environment behind the screen while imaging. It has a strong sense of technology and is more and more popular. Conventional transparent display products mainly include transparent OLED, Transparent LED, transparent projection, etc. Among them, the application of transparent OLED is limited due to its high price and size, and the resolution of transparent LED cannot meet the viewing requirements at close range. Due to its natural advantages, transparent projection has a large market among the current several types of products. [0003] Transparent projection mainly depends on the combination of projector and transparen...
