Abstract

In order to lessen the nuisance of reflections from the front surface of a CRT display, a conventional neutral density contrast-enhancing filter having an anti-reflective coating is not bonded to the CRT surface as customary, but mounted in front of the CRT in such a way that it is independently tiltable with respect to the screen. By this means, front surface reflections from the filter can be moved out of sight by operator adjustment while those from the front surface of the CRT itself are attenuated by the neutral density filter.
