second green led 1112 significantly enriches the gamut of greens and deep greens this improved system can therefore produce colors within quadrilateral boundary 1114 which is larger than triangular boundary 1104 importantly the color range outside quadrilateral boundary 1114 is smaller than for the triangular boundary 1104 in a preferred embodiment of the present invention the performance and chromacity of the leds may be specified as follows red led 1106 has cie chromacity coordinates near the 660 nm monochrome point with x y 0 730 0 270 where the x y values are expressed according to the cie standard first green led 1108 has chromacity components near the 545 nm monochrome point x y 0 266 0 724 second green led 1112 has chromacity components near 505 nm monochrome point x y 0 004 0 655 and blue led 110 has chromacity components near 465 nm monochrome point x y 0 135 0 040 other specifications will be apparent to those skilled in the art 0053 fig4 is a graphical display of the improved performance in an exemplary four led display system according to an embodiment of the invention in this chart the performance of the four color led display summarized above is shown the performance of a.
