Document Type and Number:
Japanese Patent JP2916094
Kind Code:
B2
Abstract:
A data display video monitor includes an automatic kinescope bias (AKB) control system for the type wherein kinescope cathode output pulses representative of the black current level conducted by the kinescope are produced in response to energizing the kinescope grid during sensing intervals. As a result of this operation, plural horizontal lines along the top edge of the visible display screen area are illuminated. To reduce the visible effect of the illuminated lines, the AKB system is activated for short sensing intervals (e.g., two seconds or less) between considerably longer holding intervals (e.g., five minutes).
