Problems solved by technology

However, the ductility of the existing photonic film is very poor, and it can only be used for flat glass products. For larger glass products (spherical surface ratio ≥ 35mm / m), even when the entire projected photonic film is used for production , it will lead to serious wrinkles on the edge of the photonic diaphragm after the film is combined, which greatly affects the appearance and light transmittance of related products of the photonic diaphragm, and then affects the projection imaging effect

Abstract

The invention provides a photon diaphragm and transparent projection display glass, the photon diaphragm is cut into at least two parts, and the spherical surface ratio of any part is not greater than a threshold value. The transparent projection display glass comprises first outer glass, a first bonding layer, a photon diaphragm, a second bonding layer and second outer glass which are stacked in sequence. The photon diaphragm provided by the invention can be well attached to other diaphragms, and the wrinkle phenomenon caused by the problem of a large-curvature molded surface of the photon diaphragm is greatly weakened; besides, the transparent projection display glass provided by the invention adopts the photon diaphragm, so that on the premise of ensuring the projection effect, the phenomenon that the edge part is severely wrinkled after lamination caused by poor ductility of the photon diaphragm in the transparent projection display glass can be greatly reduced.

Description

technical field [0001] The invention relates to the technical field of special glass products, in particular to the technical field of lamination of photonic films and glass, in particular to a photonic film and transparent projection display glass. Background technique [0002] In the prior art, there is a photonic film that can be used for projection display and can allow light to propagate through it. The principle is to use artificial microstructures formed by periodic arrangement of media with different refractive indices. High reflection effect in visible light band to improve display performance. However, the ductility of the existing photonic film is very poor, and it can only be used for glass products with a flat surface. , After the film is combined, the edge of the photonic diaphragm will be seriously wrinkled, which greatly affects the aesthetics and light transmittance of the photonic diaphragm related products, and then affects the projection imaging effect. ...
