ABSTRACT:
A display apparatus is arranged to have pixels, each of which has a RGBW (Red, Green, Blue and White) wavelength distribution characteristic, located two-dimensionally. The display apparatus includes an input unit for inputting a signal for controlling a using ratio of a W signal, a color signal converting unit for calculating a RGBW driving signal from a RGB input signal and the W using ratio. The RGBW signal is calculated so as to control the contribution of the W signal to the image quality. The display apparatus switches the display from the contrast-highlighted display in a relatively bright lighting condition to the color-reproducibility-highlighted display in a relatively gloomy lighting condition.
