MIXED GREEN-LIGHT LUMINOPHORE AND CATHODE-RAY TUBE Russian patent published in 2000 - IPC

FIELD: electronics, in particular, design of displays of personal computers. SUBSTANCE: weight percentages of constituents in luminophore are as follows: 40-90 of InBO₃:Tb; the rest is ZnS:Cu, Au, Al or ZnS:Cu, Al. In addition luminorphore may contain 10-30% of Zn2SiO₄:Mn with respect to total weight. InBO₃:Tb constituent is within range of 40-80%, the rest is ZnS:CU, Au, AL or ZnS:Cu, Al. Disclosed cathode-ray tube uses said mixed luminophore. Brightness is within range of 85-97 specific units, color coordinates are close to standard values (x=0.290, y=0.600), afterglow is within range of 3-12 ms. EFFECT: decreased flickering of luminophore, while keeping high brightness and color purity. 7 cl, 1 tbl, 1 ex
