  • Patent number: 5737036
    Abstract: A color image display apparatus utilizing a field sequential signal displays a picture normally without disturbance or deteriorating vertical resolution even when displaying an interlace image signal. The color image display apparatus is formed by a field sequential signal generator for converting a primary color signal to be interlaced into a field sequential signal, a monochrome image display apparatus for sequentially displaying a converted field sequential signal, a color apparatus 5 disposed to face a display screen of the monochrome image display apparatus to color a field sequential signal displayed on the display screen, and a control circuit for controlling timing of operations of these elements. A field judging result is supplied to the control circuit, and the control circuit operates so that a horizontal synchronizing signal of the field sequential signal is outputted continuously in a constant cycle even when an image signal to be interlaced is inputted.
