Plasma screen comprising a carrier plate, an array of addressing electrodes on the carrier plate, a ribbed structure that partitions the space between the carrier plate and the front plate into plasma cells that are filled with a gas, and comprising a front plate, an electrode array of pairs of strip-shaped discharge electrodes on the front plate, that are arranged in pairs on either side of a discharge path at an angle of tilt to the front plate, a dielectric layer having a thickness d, that covers the electrode array of pairs of strip-shaped discharge electrodes on the front plate, the distance a between a pair of discharge electrodes and the addressing electrodes in a direction transversel to the discharge channel being varied, and the thickness d of the dielectric layer being essentially constant.

Plasma screen with tilted discharge electrodes

A liquid crystal display screen comprising a liquid crystal layer and a first and a second transparent substrate flanking said liquid crystal layer, and comprising means for influencing the transmission state of the liquid crystal layer, and a phosphor layer, containing at least one phosphor in the form of phosphor dots, on the second substrate, and comprising a third substrate, which is arranged opposite the second substrate and connected with said second substrate so as to form a gastight gas discharge vessel filled with a filling gas, and comprising means for igniting and maintaining a dielectrically impeded discharge in the gas discharge vessel.

Liquid crystal display screen with backlighting

The invention relates to a plasma picture screen with a protective layer ( ) made of materials having a low electron affinity and a high resistance to sputtering.

Plasma picture screen with protective layer

A plasma display comprises a front panel, a rear panel, and, arranged therebetween, a number of gas-containing plasma cells separated from each other by partitions. The plasma cells each comprise a plasma region between two discharge electrodes and means arranged between the discharge electrodes for locally substantially narrowing the plasma region.
