More Information
Summary:Disclosed herein are glass articles, such as light guide plates, comprising a first surface (101) and an opposing second surface (102), wherein the first surface comprises an array of light extraction features (103) having a diameter of at least about 10 microns and a height ranging from about 1 micron to about 10 microns. Display devices comprising such glass articles are also disclosed herein as well as methods for producing such glass articles. The method involves depositing ink on a first surface of a glass substrate to form an array of coated and uncoated surfaces and etching the uncoated surfaces. La présente invention concerne des articles de verre tels que des plaques de guidage de lumière comprenant une première surface (101) et une seconde surface opposée (102), la première surface comprenant un réseau d'éléments d'extraction de lumière (103) présentant un diamètre d'au moins environ 10 microns et une hauteur allant d'environ 1 micron à environ 10 microns. Des dispositifs d'affichage comprenant de tels articles de verre sont également décrits, ainsi que des procédés de production de tels articles de verre. Le procédé consiste à déposer de l'encre sur une première surface d'un substrat de verre pour former un réseau de surfaces revêtues et non revêtues et à graver les surfaces non revêtues.
