Title:
PRIVACY FILM, DISPLAY APPARATUS, AND METHOD OF DISPLAYING IMAGE IN DISPLAY APPARATUS
Document Type and Number:
WIPO Patent Application WO/2020/252736
Kind Code:
A1
Abstract:
A privacy film includes a first conductive layer(10); an emitting angle limiting spacer layer(20) on the first conductive layer(10); a second conductive layer(30) on a side of the emitting angle limiting spacer layer(20) away from the first conductive layer(10); and a plurality of light diffuser particles(P) in a space between the first conductive layer(10) and the second conductive layer(30). The emitting angle limiting spacer layer(20) includes a plurality of spacers(S) defining a plurality of light emitting regions. The second conductive layer(30) is spaced apart from the first conductive layer(10) by a first distance(d1). A maximum height(h) of the plurality of spacers(S) relative to a surface(S1) of the first conductive layer(10) facing the second conductive layer(30) is less than the first distance(d1). The second conductive layer(30) is spaced apart from a surface(S2) of a respective one of the plurality of spacers(S) facing the second conductive layer(30) by a second distance(d2).
