Abstract

L'invention concerne un plan arrière pour un panneau d'affichage souple, comprenant : un premier plan arrière comprenant au moins deux premiers sous-plans arrière mutuellement connectés, deux premiers sous-plans adjacents étant mutuellement reliés au moyen d'une partie de flexion pliable. L'invention concerne également un dispositif d'affichage souple comprenant un panneau d'affichage souple ayant le plan arrière ci-dessus pour un panneau d'affichage souple. Par comparaison avec l'état de la technique, l'invention consiste à agencer au moins deux plans arrière pour supporter un panneau d'affichage souple, et les plans arrière sont reliés au moyen d'une partie de flexion, ce qui permet de maximiser un angle de flexion du panneau d'affichage flexible. L'invention présente en outre une structure simple et de faibles coûts.
