Abstract
A projection display apparatus according to an embodiment of the disclosure includes: a projection unit including a light source section, a wavelength converter including a discoid member and a motor section, the discoid member including a wavelength conversion layer that converts outgoing light from the light source section to light having a wavelength range different from that of the outgoing light, and the motor section rotating the discoid member, and a spatial modulation element that generates image light by modulating light from the light source section and the wavelength converter on the basis of an inputted image signal; and a control unit that controls intensity of the outgoing light emitted from the light source section and a number of rotation of the discoid member in a state where the image light is generated by the spatial modulation element.
