摘要：A cathode ray tube beam current control apparatus for controlling the beam current in a plurality of cathode ray tubes each of which produce different colors wherein each of the cathode ray tubes have a current source circuit which is connected to a respective cathode of each of the cathode ray tubes and a current sink circuit which is connected to the cathode of each of the cathode ray tubes as well as a circuit for substracting the current of the current source circuit from the current of the current sink circuit and each cathode ray tube includes a control circuit which receives an input from the output of the circuit for subtracting and is connected to each of the cathode ray tubes so as to control their luminescence level.
