Glossary
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
Ω√∞
®º
∫
against chromaticity and lumi-
nance of standard white light in display. Among the parameters, only CIELUV gets to have proper color
space where additional two blend light appears in line segment. (refer to CIE Publication 15.2, Colorimetry
1st edition 1976, 2nd edition 1986)
Color depth
:
The number of digital bit alocated to each major color.
Color gamut
:
Physically realizable color space area.
Color reproducibility
(Refer to color gamut) :
The expression of realizable colors limited by color information distinction or fluorescent substance
chromaticity.
Color temperature, correlated
(symbol CCT) :
Seemingly temperature expressed with absolute temperature of black body radiation with the closest chro-
maticity. This can be expressed as CCT, in the form of C. S. McCamy. CCT=437N3+5517, n=(x-
0.3320)/(0.1858-y) and x, y=color coordinates of CIE 1931.
Columm electrode
:
Vertically successive electrodes. It generally refers to data electrodes. When panel is installed along the pho-
tograph, this can be arranged along the horizontal direction.
Concurrent driving method
:
Driving method to disperse address pulse and scan pulse at equal distance.
Contrast ratio Columm electrode
:
Ratio of white luminance to black luminance of image. This measurement has many parameters, so mea-
surers are required to explain the consideration for measurement to make understood the meaning of the
measurement. The parameters of contrast ratio are as follows.
n
CA - ratio of center luminance in all white screen to center luminance of all black screen on the con-
dition of light being spreading around.
n
CG - ratio of white luminance to black luminance in successive arrangement of white and black
lines at equal distance.
n
CL - ratio of white luminance to black luminance in white line against black screen of black line
against white screen.
n
CR - the ratio of white luminance to black luminance.
