AUTOMATIC CHROMA CONTROL CIRCUIT

摘要

a color signal control driving part(50) outputting the control signals of high or low level; a second switching means(17) switching color signal controlling parts(11,21,31) and a second buffer means(16) in turn according to the control signal of the color signal control driving part(50); a second buffer means(16) inversion-amplifying the color signal; a first switching means(15) inspecting the first buffer means(13); an overvoltage removing means(14) removing the overvoltage of the color signal inputted from a color signal amplifying part; and a first buffer means(13) outputting the color signal from the overvoltage removing means(14).
