Title:
DIMMING TRANSPARENT PROJECTION FILM
Document Type and Number:
WIPO Patent Application WO/2023/011161
Kind Code:
A1
Abstract:
A dimming transparent projection film (01), comprising a transparent projection layer (1) and a dimming layer (2) which are arranged in parallel. The dimming layer (2) is a transparent layer having a transmittance continuously adjustable between 0.5% and 80%. The transparent projection layer (1) diffuse-reflects reflected light to realize front projection, while presenting a real-world environment behind the transparent projection layer (1). Meanwhile, the dimming layer adjusts the intensity of light incident from a rear side by adjusting the light transmittance and without affecting the reflection imaging efficiency of the transparent projection layer (1). The dimming transparent projection film can optimize the observation effect of the front projection and a rear-side object, and is applicable to various settings.
