ABSTRACT:
White balance adjustments may be carried out using the same adjustment methods as for a simultaneous system with a field-sequential display method and costs may be reduced because only one amplifier is sufficient for driving the image-receiving tube by constructing an image output circuit for use with a field-sequential display method in such a manner that the gain of a transistor set up using drive adjustment resistors and background adjustment resistors corresponding to red, green and blue is changed over by a switch on the timing of a field synchronization signal using a white balance adjustment circuit.
