摘要： A cathode ray tube face plate construction (16; 36) for suppressing the halo on the face plate (21; 41) of the cathode ,ray tube having a face plate formed of glass with an index of refrection in the vicinity of 1.52 and with outer (22; 42) and inner surfaces (23; 43). A fluorescent phosphor screen (31;48) is carried by the inner surface (23; 43). A metallic coating (49) may overlie the phosphor screen on the side of the screen facing away from the face plate (21; 41). An absorbing filter (26; 46) is disposed between the phosphor screen (31; 48) and the face plate (21; 41) for absorbing light emitted from the phosphor screen. An angle sensitive short wave pass filter (47) is disposed between the phosphor screen (48) and the absorbing filter (26; 46) for reflecting light emitted at a high angle from the phosphor screen (48).
