Title (EN) ELECTRONICALLY SWITCHABLE PRIVACY FILM AND DISPLAY DEVICE HAVING SAME
(FR) FILM DE CONFIDENTIALITÉ ÉLECTRONIQUEMENT COMMUTABLE ET DISPOSITIF D'AFFICHAGE QUI EN EST DOTÉ
Abstract: front page image
(EN)An electronically switchable privacy films suitable for use in display devices are described. The electronically switchable privacy film comprises a pair of mutually opposing transparent electrodes; an optically transparent microstructured layer disposed between the transparent electrodes, the microstructured layer comprising a plurality of microstructured ribs extending across a surface thereof such that the microstructured ribs form an alternating series of ribs and channels; and electronically switchable material disposed in the channels, the electronically switchable material being capable of modulation between high and low absorption states upon application of an electric field across the transparent electrodes.
(FR)L'invention concerne un film de confidentialité électroniquement commutable, adapté pour être utilisé dans des dispositifs d'affichage. Le film de confidentialité électroniquement commutable comprend une paire d'électrodes transparentes mutuellement opposées ; une couche microstructurée optiquement transparente disposée entre les électrodes transparentes, la couche microstructurée comprenant une pluralité de nervures microstructurées s'étendant sur toute sa surface, les nervures microstructurées formant une série alternée de nervures et de canaux ; et un matériau électroniquement commutable disposé dans les canaux, le matériau électroniquement commutable étant capable d'effectuer une modulation entre des états d'absorption haute et basse en cas d'application d'un champ électrique aux bornes des électrodes transparentes.
