The CROMACLEAR color display tube has been developed as a display tha
t offers attractive icon quality and highly legible characters. The co
lor display tube is composed of a striped superfine pitch phosphor scr
een with slot-type shadow mask. We explain the character legibility by
Fourier transform. Moreover, the electron beam shape is improved. As
a result, the CROMACLEAR color display tube has achieved higher legibi
lity and lower moire phenomenon. This CROMACLEAR color display tube is
already mounted in new monitor series.
