ABSTRACT:
A high voltage variable resistor device includes film resistors of fixed divided resistors and a variable divided resistor, fixed resistors, a variable resistor for adjusting focus voltage, and a variable resistor for adjusting screen voltage, which are formed on the surface of an insulation substrate. The fixed divided resistors have a meandering pattern and a high resistance. One end of the fixed divided resistor is connected to a high-voltage input terminal, and the other end is connected to one end of the variable divided resistor. The variable divided resistor has an arc pattern, and its other end is connected to one end of the fixed divided resistor. The other end of the fixed divided resistor is connected to a voltage detection terminal. The fixed divided resistor having a wide width pattern having a low resistance is connected between the voltage detection terminal and a ground terminal.
