Glossary
Tip pipe :
(Refer to exhaust turbulation.)
Townsend discharge :
Self sustained plasma discharge expressed by Townsend in 1901. This discharge requires 200v voltage.
Transparent electrode :
Electrode made up of transparent electric conductive matter such as ITO.
Two eledtrode type :
Original AC plasma panel used two electrodes that provide not only sustained waveform but also write
and erase waveform.
Ultraviolet ray :
Ultraviolet light below 380nm in spectrum.
Vacuum ultraviolet :
Ultraviolet ray of wavelength below 200nm.
Viewing angle :
Vertical angle that can display the image. It is normally limited by the change in luminance and chromatici-
ty.
Viewrable screen diagonal :
Releasable screen diagonal length measured between outmost pixel edges
Viewrabel screen height :
Releasable screen height measured between outmost pixel edges
Viewrable screen width :
Releasable screen width measured between outmost pixel edges.
Visible defect :
Imperfection that prevents displaying with proper image.
Wall charge :
Pure accumulation of positive and negative charges in cell wall.
Wall charge erase pulse :
Pulse that neutralizes wall charge
Wall charge transfer curve :
Curve related to wall charge pulse parameters and the changes in wall charge.
Wall voltage transfer curve :
Curve expressed with wall transfer that is caused by any changes in electric charges including wall charges
and wall charge pulse related parameters.
White back :
White coating for minimize absorbing valid gloss, located black contrast improvement layer and fluores-
cent material.
