Picture display device of the index type |
摘要 |
Picture display device comprising a cathode ray tube whose display screen (10) is provided with index electrodes (20, 21) comprising elongated conducting elements disposed substantially parallel to an axis of symmetry (50) of the display screen (10). In operation, the magnetic field of the deflection system of the cathode ray tube induces unwanted crosstalk on said index electrodes (20, 21). By cross-connecting one end (30a) of a conducting element (31) of an index electrode (20) to the opposite side end (40a) of another conducting element (41) of said index electrode (20), said crosstalk on said index electrode (20) is reduced.
