Definitions

  • the present invention relates to a plasma display from AC voltage type, with those in the preamble of the claim 1 specified characteristics.
  • Plasma displays which often include gas discharge displays are called, the radiation is off Gas discharge processes exploited to display receive.
  • Plasma displays essentially consist of two parallel, closely spaced plates that are sealed at the edges. The volume between the Plate is filled with a gas or gas mixture.
  • the edges of the plates are led out to To be able to create tensions. Will these tensions arise appropriate way, so between them creates a discharge in the gas or gas mixture.
  • Electrodes are arranged in a matrix-like manner on each Crossing point of the electrodes a discharge area Defines what areas in the plasma display are formed in which discharges can take place.
  • Each of the discharge areas created in this way corresponds to a picture element or pixel.
  • noble gases can be in radiation visible form (light) or e.g. Radiation in ultraviolet range can be emitted. Is radiation in the UV range generated, it can also be used for excitation serve between the plates attached phosphors.
  • the Phosphors shine through their chemical Composition specific color. E.g. red, green and blue phosphors can be used by appropriate Practical choice of the voltages applied to the electrodes any color and also white can be created.
  • the radiation generated between the plates after outside can be at least one of the plates at least partially transparent and preferably made of glass manufactured.
  • the electrodes are each as Run cathodes or anodes and border directly on the Gas space.
  • the electrodes are included in the AC type covered with an insulation and coating layer and each Electrode can be both cathode and anode.
  • the at the discharge generated by ionization positive and negative charge carriers are stored on the over the Electrodes lie on the insulation and coating layer and so form a surface charge layer and thus a bias that corresponds to the applied voltage counteracts and finally to extinguish the discharge leads. If the voltage applied is subsequently reversed, ie. Anode and cathode are interchanged, so add up the bias to the applied voltages, causing the next discharge ignited at a lower voltage is like at the initial ignition.
  • the compensation layer e.g. from one Magnesium oxide layer can exist, firstly lower work function of the electrons from the Surface, thus reducing the voltages to be applied, and secondly due to their low sputtering rate Ion bombardment to increase the life of the Plasma display. Both types of plasma display can still additional electrodes are inserted to the Discharge behavior of the individual discharge cells or To be able to control pixels better.
  • a possible electrode arrangement for plasma displays from AC type with additional electrodes has a first electrode group from a large number of pairs parallel electrodes, the so-called Maintenance electrodes, and a second Electrode group from a variety of electrodes the first electrode group of vertical electrodes, the so-called ignition electrodes.
  • To the Maintenance electrodes become an AC voltage created, which makes it possible to use the Ignition electrodes ignited gas discharge again and again ignite, ie. maintain.
  • the for Maintaining the gas discharge voltage is required less than that for the initial ignition of the gas discharge required voltage, because of the above described Surface charge layer is generated a bias.

Should the Gas discharge at time tl in a pixel 5 are ignited, whose position e.g. of the Maintenance electrodes 3 and 4 and the Ignition electrode 1 is determined at this time the voltage V3 on the maintenance electrode 3 increased and additionally to the ignition electrode 1 sufficiently high voltage V1 ( Figure 5c) is applied. Consequently is through the intersection of the conservation electrode 3 and the ignition electrode 1 the pixel to be ignited clearly Are defined.
  • the potential difference V3-V1 between Maintenance electrode 3 and the ignition electrode 1 is in Figure 5d, the potential difference V4-V1 between the Maintenance electrode 4 and the ignition electrode 1 in Figure 5e and the potential difference V3-V4 between the Maintenance electrodes 3 and 4 in Figure 5f shown.
  • the discharge remains stable as long as the AC voltage on the maintenance electrodes is present or until an erase pulse is applied which Surface charge and thus the preload removed.
  • the one for igniting a gas or gas mixture necessary tension depends on the composition of the gas mixture and reached in so-called Penning gas mixtures favorable values between 100 and 200V. These mixtures mostly contain noble gases.
  • the discharge area 5 is thus defined and it becomes ensures that gas discharges only in areas 5 arise in which the electrodes the distance e exhibit.
  • the pixel size must be reduced. In order to reduce the dimensions of the Electrodes of the plasma display. The reduction in Pixel size is especially for full color displays from Significance, since these three pixel elements per pixel in the elementary colors red, green and blue have to.
