ABSTRACT:
Disclosed is a circuit for commonly controlling the contrast and brightness of both TV and TTX pictures in a TV receiver with TTX. A microcomputer processes the user's key-input for controlling the contrast and brightness of the TV or TTX pictures to generate PWM pulses, which are integrated so as to simultaneously control the contrast and brightness of the TV and TTX pictures, one of which is selectively applied to the CRT driver 7 to drive the display.
