In a method of driving a display panel, a voltage of a first polarity with respect to a reference voltage is outputted to an n-th data line and an (n+1)-th data line (‘n’ is a natural number), respectively, and a voltage of a second polarity with respect to the reference voltage is outputted to an (n+2)-th data line and an (n+3)-th data line, respectively, during an N-th frame (‘N’ is a natural number). Then, a voltage of the first polarity is outputted to the n-th data line, a voltage of the second polarity is outputted to the (n+1)-th data line and the (n+2)-th data line, respectively, and a voltage of the first polarity is outputted to the (n+3)-th data line, during an (N+1)-th frame.

A display device includes a signal controller processing an input image signal and an input control signal and outputting an image signal and a control signal. A gray voltage generator generates reference gray voltages. The control signal includes a selection signal. A data driver generates gray voltages based on the reference gray voltage, selects a gray voltage corresponding to the image signal among the generated gray voltages, and applies the selected gray voltage to a pixel as a first data voltage. The data driver applies a black data voltage corresponding to a black image to the pixel according to the selection signal.

A technique for resetting the time for driving a print head of an ink-jet printer, based on different absorptivities of papers to be printed by the ink-jet printer, optimizes the amount of ink emerging from nozzles of the head resulting in a high print resolution. The technique includes: displaying different paper types on a display; selecting one type of paper out of the displayed paper types; obtaining a head driving time corresponding to the selected paper type from a look-up table prestored in a memory device and changing the predesignated head driving time to the obtained head driving time; and printing data with the changed head driving time.
