Abstract: In a method of driving a display panel, a gate signal is outputted to the display panel based on a first control signal. A gamma-corrected analog voltage is generated. A pre-charge compensating analog voltage is generated. A data voltage waveform is generated to include the generated gamma-corrected analog voltage and the generated pre-charge compensating analog voltage during one horizontal period of the display panel. The display panel has a pixel structure in which a data line is alternately connected to first and second subpixel columns adjacent to each other. The pre-charge compensating voltage has a level different from that of the gamma-corrected analog voltage where the latter represents a grayscale level represented by a received digital data signal. According to the method, display defects due to a difference of pre-charging levels used during plural horizontal periods may be decreased so that display quality of the display panel may be improved.

Abstract: A display device includes a display panel on which an image is displayed, and a driving board. The driving board includes a substrate, a first multi-layer ceramic condenser disposed on the substrate and to which a first current is supplied, and a second multi-layer ceramic condenser disposed substantially parallel with the first multi-layer ceramic condenser and to which a second current is supplied. The first current and the second current are supplied to the first multi-layer ceramic condenser and the second multi-layer ceramic condenser, respectively, in opposite directions.

Abstract: A liquid crystal display (LCD) module and a display system including the LCD module are provided. The LCD module includes a common-voltage adjustment unit which is enabled by interfacing with an external device and thus adjusts a common voltage; a signal control unit which outputs a first reverse signal that reverses the polarity of a voltage at intervals of at least two frames; and a data driving unit which reverses the polarity of an image data voltage with respect to the common voltage at intervals of at least two frames in response to the first reverse signal.
