Abstract

PURPOSE: To control color synchronization exactly and surely by forming plural index fluorescent material stripes in the horizontal scanning start part of a picture tube also at the same pitch as an available picture area.
CONSTITUTION: Red, green, and blue fluorescent material stripes R, G and B are arraged repeatedly in order in the horizontal scanning direction on the inside face of panel 5 of a picture tube, thereby forming available picture area 6. Next, black materials 7 such as carbon are formed between stripes R, G and B and around available picture area 6, and all the surface is covered with Al metal back 8. Further, index fluorescent material stripe 11 is provided on metal back 8 between available picture area 6 and one-side horizontal scanning start part 9. At this time. the pitch of R, G and B in stripe 11 is defined as (3n±/3 (however, n is O or a positive integer), and specially, the pitch is made larger in first half part 12 of horizontal scanning start part 9 that the other part by approximately 1.5 times. Thus, exact phase signals can be obtained, and color synchronization can be prevented from being disturbed.
