摘要： A plurality of scanning electrodes and a plurality of sustaining electrodes parallel to each other are located on an inner face of a first glass substrate. Each of the scanning electrodes and each of the sustaining electrodes form a pair. A dielectric layer and a protection layer are formed on the first glass substrate in this order, covering the electrodes. A plurality of data electrodes perpendicular to the scanning electrodes and the sustaining electrodes are located on an inner face of a second glass substrate which is located opposed to the first glass substrate with a discharge space interposed therebetween. In an AC-type PDP having such a structure, at least one of the plurality of scanning electrodes and the plurality of sustaining electrodes are divided into a plurality of groups, and pulses having different phases are applied to the electrodes in different groups, thereby causing sustaining discharge. The scanning electrodes and the sustaining electrodes may be comb-like with teeth. The comb-like scanning electrodes and the comb-like sustaining electrodes are opposed to each other with a small gap interposed therebetween in the manner that the teeth thereof are in engagement with each other. In such a case, the data electrodes are located opposed to and in a longitudinal direction of the teeth of the scanning electrodes.

摘要： A plurality of filaments are stretched in parallel on a rear plate, and an insulating plate is provided so as to cover the filaments. In the insulating plate, a plurality of through-holes are formed along the longitudinal direction of the respective filaments for exposing parts thereof. Each through-hole and phosphor layers, which are provided on the insulating layer adjacent to the through-hole, constitute one unit picture element. The respective phosphor layers in the respective picture element are installed in a plurality of cavities formed in a rib provided on a lower surface of the insulating plate, whereby separated from the neighboring phosphor layers. The respective cavities function as a discharge room, with a light-transmissive front plate, formed on the rib, as a lid and a portion of the insulating plate corresponding to the phosphor layer as a bottom. The respective discharge rooms overlap the through-hole at one end in the longitudinal direction thereof. A part of the filaments is exposed to the discharge room via the through-hole so as to act as a cathode. In addition, an anode exists respectively at the other end of the respective discharge rooms. In this manner, a luminescent panel for color video display, with a plurality of picture elements arranged in a matrix with a narrowed-pitch and a high density, is provided.

摘要： The plasma display panel having brightness display ranges comprising a gradation brightness display range which displays gradation brightness corresponding to the input signals under a preset input signal level and a constant brightness display range which displays a constant peak brightness greater than the maximum brightness corresponding to input signals greater than the preset input signal level. The plasma display panel can provide the gradation display up to the maximum brightness corresponding to the input signals up to the maximum input and provide the constant peak brightness corresponding to the peak level input by adding one additional weighting bit for the higher gradation. Consequently, a high quality brightness display with high mean value of the brightness and sufficiently high peak brightness can be achieved. Furthermore, the plasma display panel enhances the brightness weighting value and the value of .gamma. for the reverse .gamma. correction when the input signals go over the preset value and decrease the values to the original values when the input signals drop below the preset value. The plasma display panel can provide the gradation display up to the maximum brightness corresponding to the input signals up to the maximum input signal and provide the gradation display up to the peak brightness greater than the maximum brightness corresponding to the input signals over the maximum input signal. Consequently, high quality display with high brightness and high contrast without exceeding the maximum permissible power consumption can be achieved.
摘要翻译：具有亮度显示范围的等离子体显示面板包括在预设输入信号电平下显示与输入信号相对应的灰度亮度的灰度级亮度显示范围和显示比对应于输入信号的最大亮度大的恒定峰值亮度的恒定亮度显示范围大于预设的输入信号电平。等离子体显示面板可以提供高达对应于最大输入的输入信号的最大亮度的灰度显示，并且通过为较高灰度级添加一个附加加权比来提供与峰值电平输入相对应的恒定峰值亮度。因此，可以实现具有高的亮度平均值和足够高的峰值亮度的高质量亮度显示。此外，当输入信号超过预设值时，等离子体显示面板增强亮度加权值和用于反向伽马校正的伽马值，并且当输入信号下降到预设值以下时将该值减小到原始值。等离子体显示面板可以提供最高达与最大输入信号的输入信号相对应的最大亮度的灰度显示，并提供灰度显示，直到最大输入信号上的输入信号对应的最大亮度大于最大亮度。因此，可以实现高亮度和高对比度的高质量显示，而不超过最大允许功率消耗。
