  • Patent number: 11048152
    Abstract: A projection-type image display apparatus is provided with a light source, a disk, a color separator, and first and second modulation elements. The disk generates color lights in a time-division manner based on emission light from the light source unit, and the color separator separates first, second, and third primary colors from the color lights generated by the disk. The first light modulation element modulates the separated first and second primary colors according to an input first image signal to generate a first image light, and the second light modulation element that modulates the separated third primary color according to an input second image signal to generate a second image light. A control circuit controls the first and second light modulation elements such that the second light modulation element becomes an ON-state during a spoke period of the disk upon displaying the third primary color as a single color.
