Claim:
1. A display drive circuit, comprising: a plurality of source amplifiers operable to drive source lines of a display panel; a plurality of preamplifiers operable to output first gradation voltages; a plurality of source circuits, each source circuit including a portion of the plurality of source amplifiers and extending with a respective width along a first direction; a plurality of resistance arrays corresponding to the plurality of source circuits, the plurality of resistance arrays operable to divide the plurality of first gradation voltages to generate a plurality of second gradation voltages, wherein each resistance array of the plurality of resistance arrays is operable ( gradation lines wired from each resistance array to opposing ends of the corresponding source circuit, the opposing ends being relative to the first direction, wherein each source circuit includes a substantially equal number of source amplifiers of the plurality of source amplifiers, wherein the source amplifiers of the plurality of source amplifiers are arrayed along the first direction, wherein each resistance array of the plurality of resistance arrays is disposed in a substantially center portion of a corresponding source circuit along the first direction, and wherein each gradation line of the gradation lines is determined to have a maximum resistance corresponding to a line length of one-half the width of the corresponding source circuit.
