    • The present invention relates to a plasma display apparatus. The plasma display apparatus includes a first layer and a second layer over an upper substrate of a plasma display panel. The first layer emits light having a peak at a first wavelength region with light emitted from a discharge space. The second layer emits light having a peak at a second wavelength region lower than the first wavelength region with light emitted from a discharge space. The first layer and the second layer are disposed over a dielectric layer of the upper substrate. The plurality of scan electrodes are divided into first and second groups and then supplied with scan signals, cycles of scan signals supplied in first and second subfields of a plurality of subfields constituting one frame are identical to each other, and scan bias voltages supplied to the first and second groups in at least any one period of an address period are different from each other.

    • A plasma display apparatus includes a plasma display panel (PDP) including a front panel with a plurality of scan electrodes and sustain electrodes formed thereon and a rear panel with a plurality of address electrodes formed thereon and a driving circuit that applies drive signals to the scan, sustain and address electrodes so that driving can be performed by time-division of one frame of an image displayed on the PDP into a plurality of sub-fields. Each sub-field includes reset, address, and sustain periods, and a first signal that gradually falls is applied to the scan electrodes during the address period. In the plasma display apparatus, after a rising signal and a falling signal are applied to the scan electrodes, the first signal is applied before or after the scan signal is applied during the address period, thereby preventing a loss of wall charges and performing stable address discharges and sustain discharges.
    • 等离子体显示装置包括等离子体显示面板(PDP),其包括具有多个扫描电极的前面板和形成在其上的维持电极,以及形成有多个寻址电极的后面板以及将驱动信号施加到扫描的驱动电路 ,维持和寻址电极,使得可以通过将在PDP上显示的图像的一帧的时分时分割成多个子场来执行驱动。 每个子场包括复位,地址和维持周期,并且在寻址周期期间逐渐下降的第一信号被施加到扫描电极。 在等离子体显示装置中,在向扫描电极施加上升信号和下降信号之后,在寻址周期期间施加扫描信号之前或之后施加第一信号,从而防止壁电荷损失并且执行稳定地址 放电和维持放电。
