摘要： A method and apparatus for displaying a gray scale of a plasma display panel, by which generation of a pseudo contour upon expression of a gray scale with respect to a moving picture is prevented when a picture is displayed on a plasma display panel. The method can prevent generation of pseudo contours of dark lines (or bright lines) so that a temporal inconsistency appears as spatial inconsistency, at a portion of a moving picture in which gray scale changes are subtle, when expressing a gray scale by temporal duplication of light emission using the after-image effect of vision. In view of the fact that a pseudo contour is generated because the movement of a pixel is not consistent with the movement of the human eye, and thus a temporal change in luminance is shown as dispersion of luminance on retinas, the present invention redistributes of sub-fields having the luminance of one cell to several cells, as many sub-fields corresponding to the inconsistency of the detected movement of a pixel with the movement of the eye. Accordingly, the movement of a pixel can be approximately consistent with the movement of the eye. Consequently, the retina of the eye can perceive the temporal stimulation of an original picture, so that pseudo contour phenomenon is reduced regardless of the moving speed of a picture.

摘要： There is provided a method for driving a discharge device, especially a plasma display panel to improve a discharge process. The discharge device driving method prevents the increase of a discharge voltage and the decrease of an operating margin since space charge is efficiently controlled to lower the discharge voltage by adding a non-discharge signal for controlling space charge to a driving signal applied to at least one of two discharge electrodes, or to a third electrode, during a discharge sustaining period of the driving signals applied to both the discharge electrodes. In particular, the effects of the present invention is markedly excellent in the case of a pulse width of 1 &mgr;s or below. Discharge can be stably sustained by using a space-charge controlling non-discharge pulse of 200 ns˜1 &mgr;s wide, according to the panel structure, physical characteristics, and the driving method. In addition, in a method for applying the space-charge controlling non-discharge pulse according to the present invention, discharge efficiency can be increased by enabling the space-charge controlling non-discharge pulse to efficiently use space charge in a discharge space during a discharge sustaining period.

摘要： A method for driving a plasma display panel having front and rear substrates opposed to and facing each other, X and Y electrode lines between the front and rear substrates and parallel to each other and address electrode lines orthogonal to the X and Y electrode lines, to define corresponding pixels at intersections. In the driving method, a scan pulse is applied to the respective Y electrode lines with a time difference and the corresponding display data signals are simultaneously applied to the respective address electrode lines to form wall charges at pixels where a display discharge is to occur. Pulses for a display discharge are alternately applied to the X and Y electrode lines to cause a display discharge at the pixels where the wall charges have been formed. Also, the pulses for display discharges simultaneously applied to the X electrode lines start after the pulses for display discharges simultaneously applied to the Y electrode lines terminate, and the scan pulses and the corresponding display data signals are applied after the pulses for display discharges simultaneously applied to the X electrode lines terminate and before the pulses for display discharges simultaneously applied to the Y electrode lines start. The power levels of pulses for display discharges simultaneously applied to the Y electrode lines are greater than the power levels of pulses for display discharges simultaneously applied to the X electrode lines.
