9. Glossary
AC PDP :
Plasma display driven by alternating current plasma electric discharge.
Address discharge(Reference : scan and data) :
Term with two meanings that can be used for both scan and data (write or erase) discharge.
Address Electrode(Reference : scan and data electrode) :
Term with two meanings that can be used for both scan and data electrodes.
Address pulse(Reference : scan and data pulse) :
Address drive wave form
Address voltage(reference; scan and data voltage) :
Address drive amplitude of vibration
Addressing :
Process that gives authorization to cells to allow for turning on and off by drive wave form.
Addressing speed :
Time necessary for writing and erasing.
ADS, address display separation :
Drive tech that separates address pulse temporarily from sustained voltage.
Aging :
The change of operation expectancy- for example, operation voltage change and luminance decline-related
characteristics.
Angular distribution :
Characteristics which change as function of angles between perpendicularity and surface.
referring to dependency on angles of, for example, luminance or chromaticity.
Aperture ratio :
Referring to the ratio of an element activation area to the gross area.
Area luminance :
Luminance measured in relatively large area.
Aspect ratio :
The ratio of screen width to height.
Auto power control :
Circuit means for controlling panel's average or maximum power.
Auxillary anode :
Anode where discharge of DC panel has little contribution to light output power.
Back ground luminance :
Referring to the panel luminance in off mode or black screen, in other words, luminance in the vicinity of
the screen.

Glossary
Barrier rib :
barriers that cross all the gaps of wafers dividing the cells in panel.
Black stripe :
black substance located in between the fluorescent areas to bring about improvement in contrast by reflec-
tion ratio decline. Generally, this is striped.
Bright defect :
defects that occur when the image is rather bright than accurate.
Brightness(Reference : luminance) :
visible and subjective quality, for example, how bright matters look or how much visible rays are per-
ceived.
Notice) Do not get confused luminance with brightness because those two are not the same. Brightness is
subjective while luminance is objective.
Brun in :
element's initial operation section that takes place until the element stabilizes or the initial expectancy expi-
ration is detected.
Bus electrode :
aggregate of sustained electrodes that are bussed together.
Cathode electrode :
cathode electrified electrode that releases electrode from element. In AC plasma panel, polarity switches in
every half a cycle.
Cell :
capacity corresponding to each electric discharge. In general, it is defined by the shape of substrates and
electrodes but can be defined by partitions.
Cell gap :
measurements identifying the gaps between substrates.
Cell pitch :
measurement that identifies the cells from the surface of substrates. It varies depending on the direction of
rows and columns.
Charge transfer curves :
curves expressing the quantity of electric charge that is transferred, as the function of drive wave form
characteristics.(for example, voltage, time and others)
Color arrangement(in other words, sub-pixel arrangement) :
term expressing the location of one pixel consisted of sub color pixels.
Color coordinates, CIE 1931 :
Color image expressing method in color dimension, originated from CIE standard of 1931, expressed by X,
Y and Z. Among those three, Y element corresponds to luminous flux that is expressed as lumen while X
and Y are values that express red and purple element of luminous flux. Colors of matter are expressed as
color coordinates pair (x, y). Here x=X/(X+Y+Z), y=Y/(X+Y+Z).
Method for colors, known as (u, v), where image colors are expressed in more even color dimension.
Colors of matter are expressed as color coordinates pair (u, v). Here, u=4X/(X+15Y+3Z),
y=6Y/(X+15Y+3Z).

Color coordinates, CIE 1960 :
Method for colors, known as (u, v), where image colors are expressed in more even color dimension. colors
of matter are expressed as color coordinates pair(u, v). Here, u=4X(X+15Y+32), y=6Y/(X+15Y+32Z).
Color coordinates, CIE 1976
Method for colors, known as (u', v'), where revised image colors are expressed in more even color dimen-
sion. v' is 1.5-fold of recommended v value of 1960. The color of matter is expressed as color coordinates
pair (u', v'). Here, u'=4X/(X+15Y+3Z ) , v'= 9Y/( X+15Y+3Z ).
Color coordinates, CIE 1976 CIELUV and CIELAB :
Three dimensional parameters expressing with u' and v' including
