Abstract:
A display apparatus includes: a display unit including a modulator that modulates a plurality of color light fluxes and a light source section that includes a plurality of light sources corresponding to at least any of the color light fluxes; a light source driver that supplies the light sources with pulse currents; and a controller that sets the cycle of each of the pulse currents and an ON-period of the pulses in the pulse current in accordance with the luminance of the light source, wherein when the luminance of any of the light sources is so set that the ON-period of the pulse current is shorter than a preset lower limit, the controller sets the length of the ON period of the pulse current to be equal to the lower limit or at a value longer than the lower limit and reduces the current value of the pulse current.
