Abstract: The display device includes spaced front and back plates (1,2). Barrier ribs are formed side by side between the plates. A first barrier rib element (4) is on the side of the backplate, a second (5) is on the side of the front plate, at one end of and in contact with the first or second barrier rib elements. A strip form first electrode (6) between the first and second barrier rib elements has an end extended onto the bed section. External signal input connections (7) are formed on the bed section so as to overlap the extended end of the first electrode. A strip form second electrode (3) is formed on the backplate in a direction perpendicular to that of the first electrode. ADVANTAGE - Improved structure for connecting electrode to external connection.

Abstract: A PDP that includes a crooked discharge path caused by first and second barriers offset from each other, the ends being in contact with each other. Auxiliary anodes are provided on the end of the first barriers facing a front plate. Auxiliary discharge light produced between the second barriers is intercepted by the first barriers forming the crooked discharge path. The PDP improves contrast of picture and is easy to manufacture.

Abstract: A method for driving a flat-panel display includes an anode and a cathode intersecting each other and right angles, and a sustaining electrode which is a plate or arranged in the same direction of the cathode or anode as strips, in which the output waveform of a sustaining electrode driving circuit is a first pulse having a predetermined period and generated with an amplitude obtained by subtracting a second voltage from a first voltage. The output waveform of an anode driving circuit is a second pulse which is generated with an amplitude obtained by subtracting a fourth voltage from a third voltage when the output waveform of the sustaining electrode driving circuit represents the second voltage, an then maintaining the fourth voltage, while writing only. The output waveforms of a cathode driving circuit is a third pulse which is sequentially generated with an amplitude obtained by subtracting a sixth voltage from a fifth voltage when the sustaining electrode driving circuit represents the second voltage. A value obtained by subtracting the fifth voltage from the first voltage is greater than a minimum discharge, and smaller than a discharge firing voltage. The method is suitable for achieving higher resolution and can widen the operational margin, which enables excellent memory operation.

Abstract: A plasma display panel (PDP) comprises a plurality of anodes (1, 12, 21) on an upper plate, a plurality of first sustaining electrodes (3, 14, 25) and a plurality of alternating second sustaining electrodes (4, 17, 24) and cathodes (2, 16, 23) on a lower plate, and a dielectric (15) on the first and second sustaining electrodes (3, 14, 25 and 4, 17, 24) and cathodes (2, 16, 23). A method for driving the PDP includes the steps of initiating a discharge by supplying a potential higher than the discharge firing voltage to the anodes (1, 12, 21) and cathodes (2, 16, 23), generating a predetermined potential between cathodes (2, 16, 23) and first sustaining electrodes (3, 14, 25) to increase the voltage generated from the discharge-initiating step, supplying a voltage higher than a discharge sustaining voltage between the first and second sustaining electrodes (3, 14, 25 and 4, 17, 24) to maintain the discharge, and supplying a narrow pulse to cathodes (2, 16, 23) for erasing the discharge.

Abstract: A plasma display panel comprises a face plate, a rear plate, a plurality of anodes, cathodes, auxiliary anodes, first barrier ribs, second barrier ribs and discharge spaces. Each auxiliary anode is interposed between each first barrier rib and each second barrier rib. The PDP is easy to manufacture due to the absence of an applied dielectric layer. The circuit for driving the plasma display panel is simplified by using a DC auxiliary discharge. The width of the cathode is not limited by the auxiliary anode, but maximized because of the auxiliary anodes placement within the discharge space, so that the higher brightness is realized by the enhanced discharge.

Abstract: A flat-panel display comprises an anode (A) and a cathode (K) intersecting each other at right angles, and a sustaining electrode (S) which is a plate or arranged in the same direction of the cathode or anode in strips. A waveform is applied to the sustaining electrode which includes a pulse having an amplitude obtained by subtracting a second voltage from a first voltage after which the pulse drops to the second voltage.
