Abstract:
A plasma display panel in which two transparent base plates are assembled together to define a discharge gas space therebetween. On each transparent base plate, a plurality of strip-like main electrodes are provided and a dielectric layer is formed to cover them and, further, third electrodes are each provided between adjacent ones of the main electrodes. The two transparent base plates are assembled together in opposing relation to each other in such a manner that their main electrodes and third electrodes are disposed substantially perpendicuar to each other in the form of a matrix. By impressing a voltage to selected ones of the main electrodes of the both transparent base plates, a discharge spot is produced at their intersecting point to provide a display. The discharge spot becomes enlarged or reduced or extends in a certain direction according to the polarity of a voltage impressed between the third electrodes of both transparent base plates and to the selection of the third electrodes to be supplied with the voltage. The discharge spot can be shifted in either direction of the row and column of the matrix.
Abstract:
A driving system for matrix type display apparatus having picture elements arranged in a matrix form, each picture element being made up of a plurality of luminous elements of different brightness levels, in which one frame forming one picture is formed with a plurality of fields. Combinations of the luminous elements of adjacent picture elements are altered at every field, and the respective picture elements are scanned in the same manner as that of scanning in television, thus providing a display.
Abstract:
A plasma display panel driving system in which, at the time of interrupting a power source, the operation of a control logic circuit is stopped before an output voltage from a sustain voltage power source becomes attenuated and, at the time of applying the power source, the operation of the control logic circuit is started after the output voltage from the sustain voltage power source is established, whereby a voltage similar to an erasing pulse is prevented from impression to the plasma display panel, thereby permitting a wall charge pattern to remain alive for a relatively long time.
Abstract:
Apparatus and method are disclosed for controlling a gas discharge display device which has sealed therein an ionizable gas and electrodes insulated by the gas and low-melting-point glass and in which an alternating sustain voltage is impressed to the electrodes and writing and erasing are achieved by a voltage pen impressed with an AC control voltage and in which the magnitude and/or frequency of the sustain voltage is altered, thereby to ensure writing and erasing.
Abstract:
Plasma discharge display apparatus is disclosed, comprising an airtight envelope for receiving discharge electrode pairs formed on a common base plate and a dielectric layer formed overlaying the discharge electrode pairs. The discharge characteristics between the discharge electrodes of the respective pairs are made uniform irrespective of the curvature of the base plate and the shape of the airtight envelope.
Abstract:
A display system for plasma display panels in which X- and Ydirection electrodes are disposed in opposing relation to each other with a discharge gas sealed space being defined therebetween; a dielectric layer is coated on at least the Ydirection electrodes; a lateral discharge between adjacent Xdirection electrodes is sequentially shifted; a vertical discharge is caused between the X- and Y-direction electrodes in accordance with the timing of the lateral discharge shifting and the timing of a write-in voltage selectively impressed to the Ydirection electrodes, the vertical discharge thus caused being stored as a wall voltage in the dielectric layer; and a sustain voltage is impressed between the X- and Y-direction electrodes after writing of one line or one picture frame to provide a display in accordance with the wall voltage pattern.
Abstract:
The present invention relates to a plasma display panel comprising two substrates defining a gap in which an ionizable gas is disposed. On at least one of the substrates there are a plurality of electrodes disposed on the side thereof closer to said gap. Covering said electrodes are dielectric means which contact said gap. The dielectric means comprises a first portion having a high secondary electron emissivity and a second portion having a secondary electron emissivity lower than said first portion. The plasma display panel according to the present invention can be used to improve the definition of a displayed pattern in the plasma display panel, or as a self shift plasma display panel, and or as a pattern generator in an information processing system.
