Abstract

L'invention concerne divers modes de réalisation relatifs à un dispositif électronique comprenant des première et seconde fenêtres qui peuvent être pliées ou dépliées, un stylo pouvant être utilisé. Selon un mode de réalisation, le dispositif électronique peut comprendre : un boîtier pliable ; et un écran flexible disposé dans le boîtier pliable. L'écran flexible comprend : une première fenêtre disposée sur la surface avant de l'écran flexible ; une seconde fenêtre qui est disposée parallèlement à la première fenêtre et qui peut être pliée ou dépliée avec la première fenêtre ; un espace de pontage formé entre les première et seconde fenêtres ; et une structure de poche disposée à l'extérieur de l'écran flexible et reliée à l'espace de pontage. La structure de poche contient un liquide, et peut introduire ou évacuer le liquide dans ou depuis l'espace de pontage en réponse au pliage ou au dépliage des première et seconde fenêtres. Divers autres modes de réalisation sont également possibles.
