Title
(EN) FLAT DISPLAY SPACER STRUCTURE AND MANUFACTURING METHOD
(FR) ELEMENTS D'ESPACEMENT POUR DISPOSITIF D'AFFICHAGE PLAT, ET PROCEDE DE FABRICATION
Abstract
(EN)
A spacer structure (10) for use in a flat panel display (100), and a corresponding flat panel display article (100) are disclosed, together with an appertaining method of fabricating the spacer structure utilizing a photosensitive precursor material which is selectively irradiated, developed and etchingly processed to produce shaped standoff elements for a unitary spacer structure. The spacer structure may be dimensionally fabricated to precisely align with a selected pixel region, comprising a single pixel or an array of pixels, e.g., a color (red, blue, green) triad.
(FR)
L'invention concerne une plaque à éléments d'espacement (10) prévue pour être utilisée dans un dispositif d'affichage à panneau plat (100), et un dispositif d'affichage à panneau plat (100). L'invention a également pour objet un procédé de fabrication de cette plaque utilisant un matériau précurseur photosensible qui est irradié, développé et traité par attaque chimique, de manière sélective, pour produire des éléments de séparation mis en forme pour obtenir une plaque à éléments d'espacement. Cette plaque peut être fabriquée, de manière dimensionnelle, pour s'aligner avec précision avec une zone d'éléments d'images sélectionnée, comprenant un seul élément d'image ou un ensemble d'éléments d'images, par exemple, un triplet de luminophores (rouge, bleu, vert).
