The bulls-eye effect produced by projection television cathode ray display tubes with convexly curved faceplates and multi-layer interference filters is compensated by increasing the optical absorption of one of the filter layers having a decreasing center-to-edge thickness gradient. Since the layer is thicker in the center, more attenuation of the light output occurs there than at the edges of the display window, resulting in improved luminance uniformity of the display.

Title
Monochrome CRT with interference filter having filter layer with reduced transmission and projection color TV incorporating same
