    Abstract: A flat tube display apparatus wherein a row of many electron beam generators is arranged transversely in a thin flat vacuum tube body to generate a number of beams in parallel with each other which travel in parallel with an image screen and to deflect the beams toward the image screen at a predetermined position. The beams are guided without being widely diverged due to the provision of a number of side walls arranged in parallel with each other to confine beams and due to the provision of alternately strong and weak magnetic fields along the side walls. Image brightness can be further increased by a frit-glass-laminated structure of a multiplier or microchannel.

    Abstract: An object of the present invention is to provide a PDP driving circuit and a plasma display apparatus each of which controls a discharge current at the time of sustain discharge by carrying out a switching operation during a power source clamping while changing a turn-on time, so as to display an image whose brightness is suppressed without deteriorating the gray scale. A PDP driving circuit (701) for driving a PDP (10) is constructed by connecting in parallel at least two switching elements (S51, S52) whose turn-on times are different from each other such that the switching elements (S51, S52) can be controlled independently as switches for applying a predetermined potential to scan electrodes and sustain electrodes.

    Abstract: Barrier ribs are disposed on a back substrate so as to separate main discharge cells formed of a display electrode pair and a data electrode which face each other and priming discharge cells formed of a clearance between two adjacent scan electrodes. The top parts of the barrier ribs are formed so as to abut on a front substrate. In a driving method, in an odd-numbered line writing time period, scan pulse Va is sequentially applied to odd-numbered scan electrode SCp and voltage Vq is applied to even-numbered scan electrode SCp+1 to cause priming discharge between scan electrode SCp+1 and odd-numbered scan electrode SCp. In an even-numbered line writing time period, scan pulse Va is sequentially applied to even-numbered scan electrode SCp+1 and voltage Vq is applied to odd-numbered scan electrode SCp to cause priming discharge between scan electrode SCp and even-numbered scan electrode SCp+1.

    Abstract: In a circuit driving a capacitive load Cp, current passed through a transistor Q3, a diode D1 and a recovering coil L is passed through lines L1, L2, and the inductance components of the lines L1 and L2, and the drain-source capacitances of the transistors Q1 and Q2 generate LC resonance. Capacitors C1 and C2 are connected in parallel to the drain-source regions of the transistors Q1 and Q2 to increase the total drain-source capacitance and reduce the resonance frequency, so that unwanted electromagnetic wave radiation in a frequency band affecting other electronic devices is suppressed.

    Abstract: A method of driving an image display device is disclosed in which electron beams from line cathodes are impinged upon a display screen through beam modulating and deflecting electrodes to display an image. Each beam roughly lands onto a predetermined position on the screen by a stepped deflection voltage waveform to form a spot on the screen while the beam is deflected around the predetermined position by an unstepped deflection voltage waveform. The timing of application or the pulse width of a driving pulse signal for the beam modulating electrode is controlled in a form temporally related to the driving of the beam deflecting electrode to control the landing position or diameter of the spot on the screen. In the case where the driving pulse signal is a signal the pulse width of which is modulated by a video signal, the pulse width is changed in accordance with the level of the video signal and equally in positive and negative directions around the instant of time when a signal pulse having the minimum width necessary for representation as an image is to be generated.
