The panels significantly reduce the contrast and color rendering of the screen image when exposed to the sun (due to sun glare on the lenses of LEDs). Therefore, during the day it is required an order of magnitude higher than the night power consumption of LED panels up to 1,500 W / sq. m (due to the need to increase the brightness of LEDs by an order of magnitude up to 10,000 cd / m2).

Dans un premier mode de réalisation, l'écran est d'une conception à bandes de grille à bandes verticales. Chaque bande est pourvue d'une ou de plusieurs matrices de vidéo indépendantes de l'émetteur de lumière. Toutes les bandes sont accrochées sur une corniche de telle sorte que la largeur globale de l'écran puisse être modifiée par rotation, de manière à séparer les bandes pour former une zone d'écran et un format requis, ou de manière à ce que sur une partie ou la totalité de l'écran, les bandes puissent être rapprochées les unes des autres lorsqu'elles ne sont pas utilisées (comme dans un store à lamelles). Dans un autre mode de réalisation, l'écran avec matrice vidéo d'émetteurs de lumière a la forme d'une grille élastique noire constituée de fils d'ancrage souples et/ou élastiques et/ou compressibles et/ou de cellules recouvertes d'un matériau noir, ou avec des cellules translucides et un rideau noir en toile de fond. L'écran avec des cellules translucides, transparentes, peut être utilisé pour la visualisation d'une image actuelle à l'écran et de l'arrière-plan derrière l'écran. L'afficheur permet d'obtenir des économies d'énergie maximales et la possibilité de visualisation privée et/ou en groupe d'images identiques ou différentes sur un écran commun par différents utilisateurs dans différents points de visualisation. L'invention porte aussi sur un procédé de fabrication de tels afficheurs, qui est hautement efficace pour la production industrielle de masse d'afficheurs à l'aide d'un équipement classique avec un minimum de frais et au moyen de technologies hybrides et intégrées.
