Abstract: PROBLEM TO BE SOLVED: To provide a driving method of an AC type plasma display panel capable of improving the display quality of a display device by eliminating a defective operation by which an excessively strong discharge is generated and a displaying discharge (sustaining discharge) is generated in non-display cells in preparatory erasing discharge in which an inclined waveform is used. SOLUTION: In this driving method, the elapsed time from the completion of the preparatory discharge to the preparatory erasing discharge is made shorter (for example, 58 μs) than the three times of the attenuation time constant (for example, 18.2 μs) of quasi-stationary order atoms of xenon. Since the priming effect of the preparatory erasing discharge is sufficiently large, weak discharge is surely generated in the preparatory discharge and the excessively large discharge becomes not to be generated.

Abstract: PROBLEM TO BE SOLVED: To increase luminous efficiency without increasing the drive voltage by setting pressure of discharge gas, a product value of an interval between a pair of first and second row electrode and a mixture ratio of xenon gas in the discharge gas, and the interval between the row electrodes or the mixture ratio of the xenon gas within a specific range. SOLUTION: Pressure of discharge gas is set higher than the minimum value of the Paschen curve. The product of an interval between a scanning electrode 12 and a common electrode 13 as a surface discharge interval and a mixture ratio of xenon gas in the discharge gas is within a range from 150 to 300 with the units in μm and % for the interval and the mixture ratio, respectively. The surface discharge interval of 120 μm or the mixture ratio of the xenon gas of 2.5% or smaller is set. Luminous efficiency is increased considerably in particular, when the surface discharge interval is 150 μm or larger. The mixture ratio of the xenon gas is consequently set to 2% or less. Filling pressure of the discharge gas of 400 Torr or higher is desirable.

Abstract: PROBLEM TO BE SOLVED: To provide an AC discharge type plasma display panel and its manufacturing method that can reduce luminance by pre-discharge, can dispense with the timing adjustment of the pre-charge, and has a remarkably high degree of freedom of driving and a high contrast ratio. SOLUTION: A transparent glass front board 10 and a back board 11 are arranged opposite to each other by separating them by a predetermined gap, and the inside of the gap is filled with a discharge gas and divided into multiple display cells 32 and multiple pre-discharge cells 31. Then, image display is carried out by generating the writing of display data and maintenance discharge in the display cells 32 by the pre-discharge effect from the pre-discharge cells 31. Display cell electrodes 12, 13, 19 control the discharge of the display cells 32. On the other hand, pre-discharge electrode couples 30 to generate discharge in the pre-discharge cells 31 are formed independently from the display cell electrodes and are driven and controlled independently from the display cells. The pre-discharge cells 31 are also independent from the display cells in terms of structure, driving and control and execute pre-discharge by sine-wave driving having a low driving frequency.

Abstract: PROBLEM TO BE SOLVED: To execute sure and simple erasing operation even when the dispersion of cell characteristics is increased by gradually reducing the amplitude of a maintenance pulse to erase maintenance discharge. SOLUTION: At the end of a maintenance period, the amplitude of maintenance pulses impressed to a common electrode and a scanning electrode is gradually reduced. A waveform synthesized from voltage waveforms (A), (B) impressed to the common and scanning electrodes is an inter-electrode synthetic waveform (C). When the voltage waveform (C) is impressed between the common and scanning electrodes, wall charge is neutralized by the generation of weak discharge functionally similarly to a conventinal thick width erasing method, weak discharge having an erasing function is not simultaneously generated in all cells because the amplitude of the voltage waveform is gradually reduced but erasing is executed in each cell at different timing in accordance with the dispersion of each cell characteristic. Consequently the dispersion of cell characteristics is automatically absorbed and optimunt erasing operation is attained in all cells.

Abstract: PROBLEM TO BE SOLVED: To make the setting conditions of data pulses adjustable for each emitted color and improve the display quality over the whole screen, by providing data drives, which output data pulses for writing display information to each pixel for respective kinds of color emission. SOLUTION: A data driver 5 is divided to R data driver 5a , G data driver 5b and B data driver 5c according to their color. The R data driver 5a is connected to the data electrodes 191 , 194 , ...9n-2 which form a pixel train of R; the G data driver 5b to the data electrodes 192 , 195 ,...19n-1 which form a pixel train of G and the B data driver 5c to the data electrodes, 193 , 196 ,...19n which form a pixel train of B according to emitted color. The three kinds of data drivers 5a , 5b and 5c which respectively correspond to three kinds-R, G and B- of emitted colors are capable of adjusting data pulse width, output voltage and output timing independently of each other and being set so that the writing discharges of their own emitted color pixels are properly generated.
