Title:
DISPLAY APPARATUS, FABRICATION METHOD THEREFOR, AND SMART MIRROR
Document Type and Number:
WIPO Patent Application WO/2021/233110
Kind Code:
A1
Abstract:
A display apparatus, comprising a display panel (11) and a functional substrate (21) that is located on a light emergent side of the display panel (11); the functional substrate (21) comprises: a transparent substrate (16), which is configured to have a first total reflection angle on an inner surface of a side far from the display panel (11); a specular reflection layer (13), which is located on a side of the transparent substrate (16); and a holographic film layer (15), which is located between the transparent substrate (16) and the specular reflection layer (13) and which is configured so that the propagation direction faces towards the transparent substrate and part of incident light the angle of incidence of which is within a first light incident angle range is diffracted and enters the transparent substrate (16) at a first light emergent angle, the first light emergent angle being greater than or equal to the first total reflection angle. Further provided are a fabrication method for a display apparatus and a smart mirror.
