Abstract
The present invention provides an adjustable light projection imaging film and a preparation method thereof, comprising an electronically controlled light adjusting film base layer and a transparent projection film surface layer. The projection imaging film has two states of transparency and opacity. Through the arrangement of the electronically controlled light adjusting film base layer on the transparent projection film surface layer and through the controlling of the device to make the projection film transit between the transparency and opacity, it is possible to enable the film to possess two states of displaying the projection image and not displaying the projection image, to realize the dual performances of background transparent visibility and projection display content visibility, and to meet the display needs of an adjustable light projection imaging film to automatically and randomly switch between the transparent light transmission and projection imaging in a commercial environment.
Description
technical field [0001] The invention relates to the technical field of light-adjustable projection films, in particular to a light-adjustable projection imaging film and a preparation method thereof. Background technique [0002] In projection display, projection screens are commonly used as display carriers. Conventional projection screens are opaque, so common projection screens are installed on walls or use liftable projection screens, which brings restrictions on installation conditions and limitations in use. inconvenient. Contents of the invention [0003] The technical problem to be solved by the present invention is: in order to overcome the deficiencies in the prior art, the present invention provides a dimmable projection imaging film and its preparation method. Through the control device, the projection film is switched between transparent and opaque, so that the film has two states of displaying the projection screen and not displaying the projection screen, r...
