    摘要: A plasma display panel (PDP) includes a first plurality of electrodes, a second plurality of electrodes paired with the first plurality of respective electrodes, and a third plurality of electrodes (Y, X, A). The PDP further includes a plurality of cells at crossing portions between the first and second pluralities of electrodes and the third plurality of electrodes. In the PDP, a method comprises driving a PDP for displaying a picture on the PDP by dividing a field into a plurality of subfields (SF1, SF2, ...SF8), and resetting for adjusting charges in the cells in the subfields. The resetting for adjusting charges comprises applying voltage waveforms to the electrodes so that the potential difference applied between the second plurality of electrodes and at least one of the first plurality of electrodes and the third plurality of electrodes for the resetting for adjusting charges in a predetermined one of the subfields is larger than the potential difference applied therebetween for the resetting for adjusting charges in a previous subfield.

    摘要: A driver for a plasma display panel having a plurality of scan electrodes which are independent of each other, comprising: a plurality of driver circuits provided between a first power supply line (FLG) and a second power supply line (FVH), and connected to the scan electrodes, respectively; a first power supply circuit (71) including a first voltage generator (73) and a second voltage generator (72), wherein the first voltage generator (73) supplies OFF voltage to the first power supply line (FLG) and the second voltage generator (72) supplies ON voltage (Vsc) to the second power supply line (FVH), for writing display data; and a second power supply circuit (90) charging the first and the second power supply lines (FLG,FVH) to a defined value (Vs) for causing discharges based on the display data. To reduce the required withstand voltage of the scan electrodes, each of the scan electrodes is grounded for a short period via the first voltage generator prior to applying the defined value (Vs) of voltage during a sustain discharge period.

    摘要: A method of displaying a dynamic halftone image on a display panel comprising pixels by dividing each frame of the image into subframes and by turning on and off the subframes, comprises the steps of: finding a line of n pixels that simultaneously display a specific intensity level in a frame and another specific intensity level in the next frame; calculating the sum ΔS of stimulus on a retina to be produced with a weighted corrective pulse, which will be applied to one of the n pixels, as follows: B 1 ⁢ T ≦ B 2 ⁢ T + ΔS ≦ B 3 T, or B 1 ⁢ T ≧ B 2 ⁢ T + ΔS ≧ B 3 T where T is a period in which the intensity level of the n pixels changes from one to another, B 1 is an average of stimulus on a retina due to one of the n pixels before the change, B 2 is an average of stimulus on the retina due to the same during the change, and B 3 is an average of stimulus on the retina due to the same after the change; comparing the intensity levels with each other; selecting the weighted corrective pulses, which turn on/off corresponding subframes thereby to enable/disable corresponding intensity levels, respectively, according to the n pixels and a change in the intensity levels between the frames, so that the total sum of stimulus on the retina to be produced with the corrective pulses is substantially equal to nΔS; and adjusting original display signals for the n pixels according to the weighted corrective pulses, respectively.
