Abstract
PURPOSE: To reduce greatly the difference of luminance caused by the display colors by controlling the bias voltage between the cathode and the grid of each electronic gun based on the conducting state of the driving transistor to which the input signal is supplied.
CONSTITUTION: The bias voltage between the cathode and the grid of each electronic gun is controlled based on the conducting state of driving transistor Tr2 which is connected between the cathode and the grid and receives application of the input signal. Then the lihgt emission of each display color is controlled, and thus the active bias voltage of Tr2 is controlled according to the combinations of the input signals. As a result, the difference of the luminance caused by the display colors can be reduced greatly.
