Image retention :
Continuous existence of image after the stimulation is removed.
Image sticking :
(Refer to Image retention)
Interconnect pad groups :
A group of connection terminals that attach to individual connector. (also referred to as terminal block.)
Interconnect pad pitch :
Mutual measurements for individual of interconnect pad group.
Interconnect pad spacing :
The size of non-electric conductive area between individual terminal.
Inter-electrode gap :
In Three electrodes plasma panel, the measurement of sustained voltage separated from outside discharge space.
Ion bombardment :
The bombardment of energetic ions in the surface of solid matter. The transfer of kinetic energy toward surface
from ions can cause electron release, ion or neutron release and temperature change in surface.
Life time :
Time during device exerts its function. Commonly known as mean time failure (MTTF).
Low melting point glass :
Glass of which melting point (temperature with viscosity of 1014.5 poise) is relatively low.
Since glass is non- crystalline, the word melting is not appropriate, but it gets more fluid as it becomes hot.
Luminance :
Colloquial term for measurement of brightness of display.
It also refers to display related CIE Y constituent. It is expressed by cd/m2.
Luminance efficacy :
It refers to gloss output against the total display consumption power. It is calculated by the value generated
through dividing gloss output of white substance with gross consumption power. It is expressed as lumen/ watt.
Luminance efficiency :
It refers to gloss output against the total display consumption power, It is calculated by the value generated
through dividing gloss output of white substance with white screen power consumption increase against black
screen. It is expressed as lumen/watt.
Luminance loading :
Luminance decline that takes place when white square luminance increases into full size all white squqre.
Matrix(type) PDP :
Plasma display panel made up of matrix with rows and columns.
Matrix type :
Refer to matrix PDP
Maximum firing voltage :
Voltage value required for triggering discharge in all cells.
Maximum sustain voltage :
Maximum drive voltage required not to turn off the cells.
Memory margin :
The disparity between the maximum sustained voltage for keeping discharge and the sustained voltage for turning
off the cells.
Memory type PDP :
Refer to AC Plasma Panel that has memory. PDP made up of cells that keep turned on or off until switch occurs.
