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).
