PDP R&D Center
Thermal compaction :
Substrates successive density increase observed by substrates pattern contraction.
Thermal radiation :
Radiation in infrared rays over 800mm.
Three electrode type :
Modern AC panel has three electrodes for each cell and a pair of thermal electrodes provide cells with AC power.
Data electrodes in opposite substrates provide unique writing and erasing signals to each cell
Time modulation driving method (Other terms : time division multiplex method) :
Modulation method in proportion to certain time applied to stimulation with regular output. Output strength is
changed according to input time.
Tip pipe :
(Refer to exhaust turbulation.)
Townsend discharge :
Self sustained plasma discharge expressed by Townsend in 1901. this discharge requires 200v volts
Transparent electrode :
Electrode made up of transparent electric conductive matter such as ITO.
Two electrode 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 chromaticity.
Viewrable screen diagonal :
Releasable screen diagonal length measured between outmost pixel edges
Viewrable screen height :
Releasable screen height 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 fluorescent
material.
Write electrode :
(Refer to data electrode)
