Abstract
In a video monitor for display alphanumeric data on a kinescope display screen, a kinescope driver transistor receives binary video data signals at a low impedance emitter input electrode and provides high level video data output signals to the kinescope from a collector output electrode. A source of adjustable control voltage is coupled to the base electrode of the driver transistor for varying the intensity of the data display.
