Definitions
- the invention relates to a plasma screen equipped with a front panel, which a Has transparent plate on which a first dielectric layer and a first protective layer are applied, with a support plate, with a rib structure, which the space divides between the front plate and the carrier plate into plasma cells which are filled with a gas and with one or more electrode arrays on the front plate and the carrier plate for the generation of silent electrical discharges in the plasma cells, in which UV Light with a wavelength> 172 nm is created.
- Plasma screens allow color images with high resolution, large screen diagonal and are of compact design.
- a plasma screen has a hermetically sealed one Cell filled with a gas with electrodes arranged in a grid on.
- a gas discharge is caused by the application of an electrical voltage Generates light in the ultraviolet range. This light can be turned into visible light by fluorescent materials Light can be converted and emitted through the front panel of the cell to the viewer.
- a matrix arrangement of the electrodes There are two main types of plasma screens: a matrix arrangement of the electrodes and a coplanar arrangement of the electrodes.
- the matrix arrangement becomes the gas discharge at the intersection of two electrodes on the front and the carrier plate ignited and entertained.
- the coplanar arrangement of the electrodes With the coplanar arrangement of the electrodes, the Maintain gas discharge between the electrodes on the front panel and at the cross point ignited with an electrode, a so-called address electrode, on the back plate. In this case, the address electrode is located under the phosphor layer.
- the front panel has a protective layer made of MgO on.
- MgO has a high ion-induced secondary electron emission coefficient and thus reduces the ignition voltage of the gas.
- a xenon-containing gas is used in plasma screens a plasma discharge generates light in the VUV (vacuum ultraviolet) wavelength range. It is disadvantageous that MgO absorbs in the VUV wavelength range.
- VUV light With the coplanar arrangement of the electrodes, about half of the gas discharge occurs generated VUV light on the front panel, where it absorbs in the layers there becomes. For some of the VUV light, this effect is intensified because the VUV light is reabsorbed in the gas space by converting gas atoms from the ground state into an energetic one higher state. The light is then emitted again but distracted from its original direction, so that even light that originally has spread in the direction of the phosphor layer, can reach the front panel.
- Another disadvantage of such a design of the plasma cells is that the different Phosphors that cover the address electrodes, different plasma-phosphor interactions and thus different addressing voltages for the different plasma cells occur. This narrows the electrical margins within which the plasma screen can be operated.

- Such a plasma screen has the advantage that there are no plasma-phosphor interactions occur because the phosphor-containing layer no longer in the plasma cells, d. H. is no longer arranged between the front plate and the carrier plate. This makes the electrical Margins, within which the plasma screen can be operated, larger.
- the protective layer becomes a first layer containing fluorescent material on the front panel in a simple manner manufactured.

- a gas which is generated during a plasma discharge Radiation 10 emitted In the plasma cell, as well as between the discharge electrodes 6, 7, each of which alternately acting as a cathode or anode, there is a gas which is generated during a plasma discharge Radiation 10 emitted. After ignition of the surface discharge causing charges on a lying between the discharge electrodes 6, 7 in the plasma region 8 Discharge path can flow, a plasma forms in the plasma area 8, depending on the the composition of the gas radiation 10, being the maximum of the emitted wavelength > 172 nm is generated.
