A voltage selection apparatus and a voltage selection method applied in a driving circuit of a liquid crystal display are disclosed. The voltage selection apparatus includes a generating module, a selection module, and a setting module. The generating module generates a first curve, a second curve, and a third curve corresponding to gamma curves of R pixel, G pixel, and B pixel of the liquid crystal display under different divided voltages respectively. The selection module selects at least two common curves from the first curve, the second curve, and the third curve, and the at least two common curves have a shared region corresponding to a common divided voltage range. The setting module sets at least two pixels corresponding to the at least two common curves to use a voltage dividing resistor string in the common divided voltage range to provide voltage dividing points.
