Abstract: A display apparatus includes a display panel, a data driving part, and a timing control part. The display panel includes gate lines extending in a first direction, data lines extending in a second direction crossing the first direction, and first and second pixel groups. The first and second pixel groups are disposed at opposing sides of a data line and are alternately connected to the data line. The data driving part includes channels connected to the data lines. The channels output a data signal to the data lines, the data signal has a first polarity or a second polarity, and the second polarity has an inversed phase to the first polarity. The timing control part outputs a data inverse control signal and first and second polarity control signal, which control the polarity of the data signal based on the data inverse control signal.

Abstract: A display panel apparatus includes a display panel and a timing controller, and a data driver. The display panel includes a first subpixel and a second subpixel. The timing controller is configured to receive a first subpixel data for the first subpixel and a second subpixel data for the second subpixel.

Abstract: A plasma display panel is provided that has an inter-electrode distance in a structure where a black layer and an electrode are separated from each other. The plasma display apparatus may have the effect that reactive current is reduced by lowering capacitance. Further, the plasma display panel may have the effect that emission of light by discharge is smoothly performed by controlling a width of an upper and lower portion of a second barrier rib and a width of the first barrier rib according to the width of the upper portion of the second barrier rib such that a luminance can be increased and interference of adjacent cells can be minimized. This may have an effect that a sustain period where an image is displayed can be secured relatively longer since an address time during which the scan pulse is applied is reduced.
