System and method for displaying a color picture

A method for displaying a color picture, comprising:

• receiving and storing a color picture signal, which includes a plurality of signal components per field, in a field sequential signal generating means at a first rate;
• sending a vertical sync signal, which includes a plurality of vertical sync pulses corresponding to the plurality of signal components respectively, from a control means to a picture display means;
• sequentially sending the plurality of signal components, as a field sequential signal, from the field sequential signal generating means to the picture display means at a second rate which is higher than the first rate, thereby displaying a monochromatic picture based on the plurality of signal components on the picture display means;
• coloring light emitted from the monochromatic picture displayed on the picture display means;
• and
• controlling a timing at which each of the plurality of vertical sync pulses is sent to the picture display means by selecting a vertical sync signal from among a signal with a period equal to one-third a triple-rate vertical sync interval or a triple-rate vertical sync signal that is delayed for a period of time equal to one-half the period of a horizontal sync signal,;
• wherein the respective time intervals between when the plurality of vertical sync pulses are sent from the control means to the picture display means and when the signal components are sent from the field sequential signal generating means to the picture display means are equal and a period between the plurality of vertical sync pulses varies according to the selected vertical sync signal.

A system for displaying a color picture, comprising:

• a field sequential signal generator, said field sequential signal generator receiving a color signal including a plurality of signal components per field at a first rate and transmitting the plurality of signal components as a field sequential signal at a second rate which is higher than the first rate;
• a picture display apparatus operatively connected to said field sequential signal generator for displaying a monochromatic picture based on the plurality of signal components transmitted from said field sequential signal generator;
• a coloring apparatus operatively connected to said picture display apparatus for coloring light emitted by said picture display apparatus;
• and
• a controller operatively connected to said coloring apparatus, said picture display apparatus, and said field sequential signal generator for controlling the display of the monochromatic picture by selecting a vertical sync signal from among a signal with a period equal to one-third a triple-rate vertical sync interval or a triple-rate vertical sync signal that is delayed for a period of time equal to one-half the period of a horizontal sync signal.
