Abstract: A display device driving method, suitable for a driver circuit, includes the following steps: determining magnitude of a plurality of data voltages according to received display data, and the plurality of data voltages are configured to be transmitted to a plurality of pixel circuits via a plurality of data lines; comparing the magnitude of the plurality of data voltages to generate a comparison result; and before providing corresponding ones of the plurality of data voltages to a first pixel group arranged at an i-th row of the plurality of pixel circuits, providing a first reset voltage having a value determined according to the comparison result to the plurality of data lines, or providing a second reset voltage to m data lines selected according to the comparison result from the plurality of data lines, i is a positive integer, and m is an integer.
