Apparatus and method for displaying graphic object with low power consumption

Abstract

Provided are an apparatus and method for displaying a graphic object with low power consumption, more particularly, an apparatus and method for displaying a graphic object with low power consumption that reduces power consumption by adjusting complexity and surfaces properties of the graphic object that is displayed and increasing transmittance of light emitted a light source of a liquid crystal display device. The apparatus includes a remaining power checking unit checking the remaining amount of power that is supplied, a graphics management unit converting properties of the graphic object on the basis of the remaining power, a light source management unit adjusting intensity of light emitted from a light source on the basis of the remaining power, and a display unit displaying the graphic object whose properties are converted with the adjusted intensity of the light emitted from the light source.
