摘要： An AC gas discharge display panel is described which employs the phenomenon of plasma spreading. In the panel, plasma spreading or "coupling" is employed to couple the plasma to an addressed cell to one of a plurality of pixels to be illuminated. The spreading is controlled by assuring that the cell wall voltages are properly related so that the plasma's electrons migrate to a region where the voltages are approximately equal to or more positive than the wall voltages where the plasma originated. Paired sustain electrodes are selectively energized to enable diversion of the coupled plasma to the desired pixel, so that upon subsequent applications of a sustain voltage, the desired pixel is illuminated (or erased) as the case may be.

摘要： A method is described for erasing pixel cells in an ISA AC plasma display panel. The panel comprises a plurality of cell groups aligned along horizontal and vertical dimensions, each cell group including an address cell, two vertical coupling cells, two horizontal coupling cells, and four pixel cells. Horizontal and vertical address lines are provided and intersect each address cell, and sustain lines are positioned on either side of the address lines and intersect adjacent series of pixel cells and coupling cells in each cell group. Intersections between sustain lines define pixel cells by type, with each cell group having identical first through fourth types at corresponding sustain line intersections. The method comprises: energizing the address and sustain lines line to turn ON at least a selected first type pixel cell in an addressed cell group, the first type pixel cell and a second type pixel cell defined by intersections between a horizontal sustain line and first and second vertical sustain lines; applying sustain signal pulses to all the sustain lines, with at least one less sustain signal pulse being applied to vertical sustain lines which define the second type pixel cell in all cell groups; and subsequently applying to the sustain lines, a sustain potential to cause erasure of the selected first type pixels in the addressed cell groups.

摘要： A method and system are described for reducing flicker in a display panel. The method comprises the steps of sequentially addressing rows of pixels in the panel, each addressed row location made active by applied address signals during a row address period. Addressed locations along an active row emit light when addressed. During a row address period, simultaneous addresses are applied to a plurality of additional dummy rows in the panel. The addressing is accomplished with signals that do not change memory display states at locations along the additional dummy rows, but do cause locations along the additional dummy rows to emit light during each row address period.

摘要： Sustainer drive circuitry for an AC plasma display panel wherein a multiple level sustainer signal is applied to panel electrodes along one axis only. The sustainer circuit includes a pair of series connected NPN pull-high and pull-down output driver transistors which (a) are respectively driven by low voltage drive circuits isolated from the NPN output driver transistors by capacitors; (b) respectively charge up the panel to a relatively high voltage and discharge the panel to ground; and (c) include a feedback network for limiting the rise time of the high voltage across the panel for reducing noise and electromagnetic interference. Diode circuitry insures that these output driver transistors are turned on and off without ringing and are never driven on simultaneously. A common voltage supply provides both (a) the write pulse level and (b) the write pedestal level of the sustainer waveform. The invention further provides a border sustain driver circuit for one axis which comprises simple and inexpensive integrated circuit logic gates.

摘要： An AC plasma panel display includes front and back panels that respectively support a first parallel electrode pattern and a second orthogonally oriented, parallel electrode pattern. The electrode patterns define a display area and both patterns are covered by dielectric layers. A dischargeable gas is positioned between the dielectric layers in the known manner. Driver circuitry is coupled to both electrode patterns for creating a spatially continuous gas discharge along at least one continuous electrode of one electrode pattern and across the entire display area. The driver circuitry scans the spatially continuous gas discharge across remaining parallel electrodes of the one electrode pattern so as to scan the entire display area. A further electrode is in DC conductive communication with the gas and is positioned outside of the display area but in contact with the spatially continuous gas discharge during its scanning action. The electrode provides a capacitive structure which prevents a build-up of an excessive static charge on the dielectric layers and thereby prevents dielectric breakdown.

摘要： An AC gas discharge logic device with two input electrodes and an output electrode isolated by dielectric material from a dischargeable gas. Upon coupling suitable signals to the input electrodes, the gas is discharged and a voltage level at the dielectric material associated with the input electrodes is established which is different than the initial voltage level at the dielectric material associated with the output electrode. The subsequent voltage level of the output electrode after the gas discharge thus approaches the established voltage level at the input electrodes. An AC gas discharge panel with a plurality of the aforementioned logic devices included within the panel structure.

摘要： An AC PDP has a plurality of addressable subpixel sites, each subpixel site including an address electrode positioned on one substrate and first and second sustain electrodes positioned on an opposed substrate. An intersection between the address electrode and the first sustain electrode defines a first discharge site and an intersection between the address electrode and the second electrode defines a second discharge site. A scan driver is active during an address phase, and applies a negative going signal to the first sustain electrode. An address driver applies an address signal to the address electrode which creates a discharge at the first discharge site. As a result, a positive column moves along the address electrode to the second discharge site and causes a discharge thereat which induces a wall voltage at the second discharge site in accordance with a determined subpixel value. A sustain driver applies a sustain signal to both the first sustain electrode and the second sustain electrode and creates a “ping pong” action of the wall charge states at the discharge sites and enables the use of positive column light emission in the PDP.

摘要： A method for driving an Independent Sustain/Address line (ISA) AC plasma display panel comprises the steps of: energizing address and sustain lines to turn on all four pixel cells in a cell group; applying an erase pulse to an address cell to cause a first coupling cell in the cell group to have wall charges deposited therein; applying next, a preset duration potential between intersecting sustain lines, one sustain line intersecting the first coupling cell and firs and second adjacent pixel cells, to migrate electrons from a discharge of the first coupling cell to a first adjacent pixel cell to erase the pixel cell, such potential further causing an "on" pixel cell adjacent to the first coupling cell to discharge; applying next, another erase pulse to an address cell, to cause a different coupling cell to have wall charges deposited therein; and applying next, a lesser duration potential than the preset duration potential, between a pair of intersecting sustain lines to migrate the deposited wall charges to a pixel cell adjacent the different coupling cell to erase to pixel cell, such lesser duration potential being insufficient to cause another pixel cell adjacent the different coupling cell to discharge.

摘要： An improved address driver circuit for plasma panels, particularly useful with an independent sustain and address plasma panel. Address pulse generators for one panel address axis are coupled to MOSFET driver devices and provide pulses of a first polarity; and address pulse generators for the other panel address axis are coupled to similar MOSFET driver devices and provide double pulses of a second polarity. With N-channel open-drain MOSFET drivers on both panel address axes, they only need to be designed to pull low. An improved power efficient sustain driver for plasma panels including an inductor through which the panel capacitance is charged and discharged, and switch means switched when the inductor current is zero, which permits recovery of the energy otherwise lost in driving the panel capacitance. An independent sustain and address plasma panel with such energy efficient address drivers and sustain drivers. The energy efficient sustain driver can be used with plasma display panels, electroluminescent panels and with liquid crystal panels having inherent panel capacitance. An independent sustain and address panel with N-channel MOSFET drivers on one address axis and P-channel MOSFET drivers on the other address axis, with an address pulse generator providing pulses of a first polarity to the N-channel MOSFETs, and another address pulse generator providing pulses of a second polarity to the P-channel MOSFETS.
