An apparatus and a method for displaying a graphic object with low power is provided to minimize the power consumption by adjusting the complexity of a displayed graphic object in consideration of the power residue of a power supply unit and increasing the light source transmittance of an LCD unit. A graphic management part(250) in an apparatus for displaying a graphic object with low power consists of a model transformation part(251), an operation load management part(252), and a pixel information transformation part(253). The model transformation part(251) transforms the polygon model of a graphic object. The operation volume management part(252) adjusts the frequency of calculation for the vertex coordinates and color tone of the polygon model. The pixel information transformation part(253) transforms the resolution of pixel information, applied to a specific area of the graphic object, based on a previously created pixel information map.
