摘要： A method for activating the cells of an image display screen. Electric potential signals called activation signals are produced to activate the cells and to supply the current consumed by this activation. An electric potential is applied to a solenoid so as to develop the activation signals at the solenoid terminals and to cause a change in the main current in the solenoid which serves as the current consumed by the cell activation. Thus, cell activation control of the “current supply” type is effected, and is particularly suited for the delivery of large amounts of current in a short time. This may be used in image display screens such as plasma panels.

摘要： A process for controlling a display panel having cells defined by the intersection of two networks of crossed electrodes. The cells have two states, one written and the other erased. A square-wave hold signal on either side of a middle potential is applied to all the cells to produce a hold discharge with regard to the cells in the written state, at the termination of the edges leading to an extreme porch. It also includes applying an addressing signal superimposed on the hold signal in succession to the electrodes of a network. The addressing signal includes a semi-erase-selective signal generating, with regard to the cells linked to the selected electrode, an erase discharge at the termination of an edge leading to an extreme porch of the hold signal. This disables the whole discharge generated by the hold signal alone. This method is applicable to the control of plasma display panels.

摘要： An apparatus and a method for the control of a display screen, especially a plasma panel screen. The screen has cells that can be either in an erased state or in a "recorded" state in which they can be activated by alternating signals called sustaining signals. According to one characteristic, the method consists in dividing the cells into at least two groups, such as an upper group and a lower group, these two groups receiving sustaining signals alternately, and in applying to the cells, during the time when they do not receive the sustaining signals, memory signal enabling them to preserve their "recorded" state or their "erased" state. This results in a reduction of the pulsed discharge current.

摘要： A novel drive system is described for AC plasma (ACP) gas discharge flat bistable matrix panels on which real-time video and computer graphics, both with pixel by pixel gray scale are displayed. The drive scheme increases scan speed, reduces complexity and minimizes circuitry required to operate the video and computer graphics gray scale images on the ACP display through: a) unique application of standard high density memory IC architecture, and b) unique panel drive waveform technique. Flicker is avoided with an interlaced framerate of 46 Hz and non-sequential pixel row scanning. The unique panel drive scheme allows high speed operation to avoid flicker in the ACP panel for real time gray scale video and graphic images. Because of the high speed addressing requirements, the panel waveform techniques apply all of the drive voltages to the ACP panel from the row (Y) axis and only selective cancellation voltage from the column (X) axis. This technique results in ground based data transfer from the memory circuits to the column driver ICs, and eliminates significant level shifting through multiple parallel isolation circuits such as transformers or optical couplers. Avoidance of isolation circuits in the X-axis allows higher speed transfer of data into column drivers. The panel addressing requirements for pixel-by-pixel gray scale is minimized through geometric accumulation of pixel on-time per frame. At least 64 levels of gray scale are provided in standard neon ACP displays with pixel rows of 256, 480 and 512, for example.

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.

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 at 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： The invention provides voltage potential differences for selectively discharging cells in a plasma display device, with greater brightness and reduced power consumption. The plasma display device has orthogonally related electrodes sealed in an atmosphere of neon gas. When a predetermined potential is applied between two intersecting electrodes, the neon gas glows at the intersection. The predetermined potential is achieved by applying two pulse trains which have opposite phases and therefore oppositely going voltage polarities. The difference in the oppositely going peak voltages of the two pulse trains provides a firing potential at the selected intersection. To reduce power consumption, the cell at the intersection is fired at a high potential during an address mode and thereafter held in a glowing state by a greatly reduced voltage. Another embodiment produces a similar result by changing the frequency of driving pulses in the firing and the holding modes.
