Color Gamut and Color Space Coverage The LP2480zx monitor uses an LED-backli t LCD modu le that provides an extreme ly wide color gamut. This gamut was chosen to e nclose a number of co lor spaces as defined by various standard output device specifications, which (along with other color-m anagement features in this product’s electronics) permits [...]

As plotted within the 1976 CIE u ’ v ’ color space, these gamut s are shown be low: Figure A-1 Color Space Diagram Color Space Emulation As noted earlier, the LP2480zx ha s the capability of emulating a disp lay that conforms to a number of standard outp ut device specifications, such as sRGB, Adobe RGB, and et cetera. This emulati on includes [...]

Figure A-4 Correcting Native Di splay Characteristics It can be shown tha t the required tran sform (T) may be implemented as a pa ir of appropriately-sized look-up tables (LUTs), on either side of a 3 x 3 ma trix multiplicatio n. T he LUT preceding the matrix multiplication (the “pre-LUT”) impleme nts the desired standard transf er function or[...]

Note that since the look-up tables for the three c hannels (R, G, and B) are independent, differ ences in the display device’s transfer fun ction across these th re e, along with any minor errors in the display whi te point, may be “nulled out” using th e look-up tables, in add ition to the operations required fo r the color space emulation a[...]
