METHOD OF REDUCING THE REFLECTANCE OF A TRANSPARENT VIEWING SCREEN AND VIEWING SCREEN WITH REDUCED REFLECTANCE

摘要

A viewing screen is described, in particular the screen of a display tube, which has excellent anti-reflective properties and a method of making this screen anti-reflective. In this method the outer surface of the screen is mechanically roughened in conformity with specific requirements and subsequently an anti-reflective coating of constant thickness is applied to the roughened surface.
