Limiter circuit for preventing blooming in a video display terminal
摘要:
A limiter circuit for video display terminal which produces contrast voltage comprises an amplifier for amplifying video signals received from a source thereof, and a series of transistors receiving the video signal from the amplifier, arranged for selectively limiting the occurrence of blooming on the display terminal in response to the value of the contrast voltage of the terminal.
