Abstract: A display apparatus comprises a light source which sequentially emits light of a plurality of colors, a display part which selectively projects the light emitted from the light source and displays an image, a data storage which stores a plurality of waveform data for representing a ratio of the plurality of colors, a light source driver which controls a strength of the light emitted from the light source, and a controller which selects a waveform data from the plurality of waveform data and controls the light source driver to control the strength of the light based on the selected waveform data.

Abstract: An image display apparatus comprises a plurality of light sources, each of which outputs light having a different color than the other light sources, and a digital micro mirror device (DMD) panel having a plurality of mirror elements. The plurality of mirror elements reflect light output from the light sources in one of a first direction, for displaying an image, and a second direction different from the first direction. The apparatus further includes a detecting part which detects the quantity of light reflected in the second direction by at least one mirror element of the DMD panel, and an adjusting control part which determines the quantity of light output from the respective light sources based on the detection by the detecting part, and which adjusts light output of the light sources based on the determined quantity of light output from the light sources.
