Problems solved by technology

However, traditional film preparation methods such as spray coating and evaporation cannot form a reflective layer or a light-absorbing layer on only one surface of micron-sized micro-protrusions.
As for the way of spraying, since the paint particles sprayed from the nozzle have a serious problem of divergence, it is impossible to cover only one surface of the micro-protrusion directionally, and the reflection and light absorption parts formed by these traditional methods overlap and interfere with each other. The problem

Embodiment Construction

[0031] Hereinafter, specific embodiments according to the present invention will be described in detail with reference to the accompanying drawings. It is emphasized that all dimensions in the drawings are schematic only and not necessarily true to scale, and therefore are not limiting. For example, it should be understood that the dimensions, proportions and angles of components such as the reflective layer, the light absorbing layer and the substrate in the drawings are not shown in accordance with the actual dimensions and proportions, and are only for the convenience of the drawings, but are not intended to limit the present invention. The specific scope of the invention.

[0032] like figure 1 As shown, the screen 100 of the present invention includes a plurality of light absorbing layers 101 for absorbing ambient light and a plurality of reflective layers 102 for reflecting projected light. Layer 102 as a unit forms a prismatic structure that is stacked to form a jagge...

Abstract

The object of the present invention is to provide a screen comprising several light-absorbing layers that absorb ambient light and several reflective layers that reflect projected light, the number of said light-absorbing layers and said reflective layers is equal, each of said light-absorbing layers and Each of said reflective layers as a unit forms a prismatic structure stacked to form a saw-toothed structure on a viewing surface.

Description

technical field [0001] The present invention relates to a screen and a manufacturing method thereof. Background technique [0002] Currently, there is a huge demand for projection screens under conventional lighting conditions. But projection screens, which are limited to use in darkroom conditions, have their own limitations. For example, ambient light can have a large effect on the quality of the projected image, possibly reducing image contrast. Although high-intensity projection light sources can reduce the influence of ambient light and improve contrast, one of the disadvantages of high-intensity light sources is that they do not save energy, and more importantly, high-intensity light sources tend to have the disadvantage of being very dazzling. [0003] In this case, the black grid projection screen is a new generation of optical screens specially designed for high-brightness environments. In the black grid projection screen, the side facing the ambient light of the...
