Patent ID: 7728827

Claim:
A method for driving a display device including a plurality of pixel circuits coupled to a plurality of data lines for transmitting data currents for displaying an image, and a plurality of signal lines each corresponding to at least two of the plurality of data lines and transmitting currents corresponding to the data currents corresponding to the at least two of the plurality of data lines, the method comprising: applying a first precharge current to one of the plurality of signal lines; applying to said one of the plurality of signals lines a first current corresponding to the data current to be applied to a corresponding first data line from the at least two data lines; applying a second precharge current to said one of the plurality of signal lines; applying to said one of the plurality of signals lines a second current corresponding to the data current to be applied to a corresponding second data line from the at least two data lines; and applying the data currents corresponding to the first and second currents to the corresponding first and second data lines, wherein the first precharge current is M times the first current and the second precharge current is M times the second current, where M is a real number greater than 1.
