preparation example Construction

[0032] The preparation process of the projection glass screen 100 includes:

[0033] Step S1: After roughening the first surface of the transparent glass substrate, spraying a nanometer self-cleaning coating with photocatalysis;

[0034] Preferably, the light transmittance of the transparent glass substrate is greater than 85%, preferably greater than 90%.

[0035] More preferably, after the first surface is roughened, the roughness is 0.05-1.5 μm, or 0.1-1.3 μm, or 0.3-1.1 μm, or 0.5-1.0 μm, or 0.7-0.9 μm.

[0036] Further, the rough surface treatment is an etching method, and the depth of the groove after etching is 0.3-0.8 μm, or 0.4-0.7 μm, or 0.5-0.6 μm; the width of the groove is 130-160 μm, or 135-155 μm , or 140-150 μm, or 143-147 μm.

[0037] Further, it also includes: tempering the transparent glass substrate treated by the etching method, so as to enhance the hardness of the transparent glass substrate and improve the safety of use.

[0038] Alternatively, the ro...

Abstract

The invention provides a projection glass screen and relates to the field of imaging. The projection glass screen is in a layered structure and comprises a transparent glass substrate, a nanometer self-cleaning coating layer and a spectral absorption coating layer. The transparent glass substrate ahs a first surface and a second surface, which are opposite. The nanometer self-cleaning coating layer is contacted with the first surface; and the spectral absorption coating layer is contacted with the second surface. The first surface is a rough plane, and the roughness of the first surface is 0.05-1.5 microns. The projection glass screen can effectively reduce the intensity of reflected light, reduce dazzle light and improve imaging definition.

Description

technical field [0001] The invention relates to the field of imaging, in particular to a projection glass screen. Background technique [0002] Holographic projection technology, also known as virtual imaging technology, is a technology that uses the principles of interference and diffraction to record and reproduce the real three-dimensional image of an object. Holographic projection technology can not only produce three-dimensional aerial phantoms, but also allow phantoms to interact with performers to complete the performance together, producing shocking performance effects. [0003] In recent years, with the rapid development of holographic projection technology, some holographic projection glasses for projection have emerged on the market. The imaging effect of this kind of holographic projection glass is good, but if you watch it for a long time, it is easy to cause visual fatigue, and the customer experience is not good. Contents of the invention [0004] The obje...
