Abstract: PURPOSE:To increase brightness by permitting a beam current to flow sufficiently when a temperature is low by connecting a thermistor with a positive temperature characteristic thermally coupled to a coolant to a beam current detecting resistor in an automatic limitation circuit. CONSTITUTION:When the temperature of the coolant 3 is low, the resistance value of the thermistor 11 is small, and synthetic resistance with a detecting resistor 8 is small. At this time, when the beam current that flows from a power source line 10 to supply lines 5a, 5b, and 5c is small, voltage drop by the synthetic resistance is small, and a Zener diode 12 is turned ON, and potential at a point (m) goes to 12V, and a transistor 13 is turned OFF, and no automatic brightness limitation ABL is applied. When the beam current is increased, the transistor 13 is turned ON after turning OFF the diode 12, and the ABL is applied, and the beam current is increased remarkably, and high brightness at the peak of a video signal can be obtained sufficiently. When the temperature is high, the resistance value of the thermistor 11 is large, and the ABL is applied with a small beam current, and the beam current and the brightness can be suppressed.
