Title:
PHOTONIC FILM AND TRANSPARENT PROJECTION DISPLAY GLASS
Document Type and Number:
WIPO Patent Application WO/2023/198185
Kind Code:
A1
Abstract:
A photonic film (6) and transparent projection display glass. The photonic film (6) is cut into at least two parts, wherein a spherical ratio of any part is not greater than a threshold value. The transparent projection display glass comprises: first outer glass (4), a first bonding layer (5), a photonic film (6), a second bonding layer (7) and second outer glass (8), which are sequentially stacked. The photonic film (6) can be well fitted with other films, and the wrinkle phenomenon of the photonic film (6) caused by the problem of a large-curvature profile is greatly weakened. In the transparent projection display glass, by means of the photonic film (6), while the projection effect is ensured, the phenomenon that the edge of the photonic film (6) inside the transparent projection display glass has severe wrinkles after film combination due to poor ductility of the photonic film (6) can be greatly reduced.
