Beschreibung
Zusammenfassung:	A glass article that is ion-exchangeable and has at least one roughened surface. The roughened surface has a distinctness-of-reflected image DOI of less than 90 when measured at an incidence angle of 20°. A pixelated display system that includes such a glass article is also provided. L'invention concerne un article en verre qui est apte à l'échange d'ions et qui comprend au moins une surface rugueuse. Ladite surface rugueuse présente une netteté d'image réfléchie DOI inférieure à 90 lorsqu'elle est mesurée à un angle d'incidence de 20°. L'invention concerne également un système d'affichage pixélisé comprenant un tel article en verre.
