Abstract:
A light source apparatus includes a light source module, a luminance determiner, an illuminance sensor and a light source driver. The light source module provides a display panel with light. The luminance determiner obtains luminance data of first image data including at least white image data that is converted from image data of a red color, a green color and a blue color. The illuminance sensor obtains sensing data based upon an external illuminance. The light source driver drives the light source module based upon the luminance data and the sensing data.
