    摘要： An image display device is provided, which can secure a predetermined display quality regardless of a type of an input image. The color image display device (100) comprises a display device (1) having a delta arrangement screen, a driving circuit (80), and a data conversion circuit (70). The data conversion circuit (70) comprises an image decision circuit (71) for deciding which of plural predetermined types an input image is, a memory circuit (72) for memorizing temporarily at least a part of input image data for one frame, an operation circuit (73) for performing an operation process having preset contents in accordance with image data for plural pixels including image data read out of the memory circuit, and an operation control circuit (74) for switching the contents of the operation process in the operation circuit in response to the output of the image decision circuit.

    摘要： A method of driving a plasma display panel is disclosed in which background light emission is reduced so that display contrast is improved. The method comprises the steps of resetting for equalizing wall charge in cells constituting a screen, addressing for controlling potentials of address electrodes crossing display electrodes in accordance with display data, and sustaining for applying a sustaining voltage to the cells so as to generate display discharges. The address electrodes are grouped in accordance with discharge characteristics of cells corresponding to each address electrode. In the resetting step, potential control that is unique to each group is performed so that luminance of the discharge light emission in the reset becomes uniform among cells having different discharge characteristics.
