摘要： In a plasma display device having a three-dimensional matrix wiring arrangement of anodes (24), cathodes (27) and address electrodes (22), writing discharge is caused between anodes (24) and address electrodes (22) to temporarily store writing charge on a dielectric layer (23), and the writing charge is discharged as an auxiliary discharge by applying a sustaining voltage to the cathodes (27), thereby inducing main discharge between the anodes (24) and the cathodes (27).

摘要： A plurality of filaments (8) are stretched in parallel on a rear plate (7), and an insulating plate (11) is provided so as to cover the filaments. In the insulating plate, a plurality of through-holes (12) are formed along the longitudinal direction of the respective filaments for exposing parts thereof. Each through-hole and phosphor layers (13), which are provided on the insulating layer adjacent to the through-hole, constitute one unit picture element. The respective phosphor layers (13) in the respective picture element are installed in a plurality of cavities (15) formed in a rib provided on a lower surface of the insulating plate, whereby separated from the neighboring phosphor layers. The respective cavities (15) function as a discharge room, with a light-transmissive front plate (16), 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 (17) 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 (1) which displays gradation brightness corresponding to the input signals under a preset input signal level (LM) and a constant peak brightness display range (2) which displays a constant peak brightness (P) greater than the maximum brightness (M 3 ) corresponding to input signals greater than the preset input signal level (LM). The plasma display panel can provide the gradation display up to the maximum brightness (M 3 ) corresponding to the input signals up to the maximum input signal level (LM) and provide the constant peak brightness (P) 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 γ for the reverse γ 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 M 3 corresponding to the input signals up to the maximum input signal level LD and provide the gradation display up to the peak brightness P greater than the maximum brightness M 3 corresponding to the input signals over the maximum input signal level LD.

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.
