Abstract:
A method for fabricating a backlight source includes determining an n-step MacAdam ellipse in a uniform chromaticity diagram, where n is an integer smaller than or equal to 3; and fabricating the backlight source according to chromaticity coordinates within the n-step MacAdam ellipse to cause chromaticity coordinates of light emitted from different ones of light-emitting diodes of the backlight source to be within the n-step MacAdam ellipse.

Claim (Index 10):
The fabrication apparatus according to  claim 9 , wherein the processor is further configured to:\n determine at least one initial ellipse according to the isothermal line segment and the intersection, each of the at least one initial ellipse having the intersection as a center point, and the two endpoints of the isothermal line segment being on each of the at least one initial ellipse; match the at least one initial ellipse with an m-step MacAdam ellipse in the uniform chromaticity diagram to determine, from the at least one initial ellipse, a largest initial ellipse containing the m-step MacAdam ellipse, wherein n\u2264m\u22647; determine a chromaticity-region quadrilateral according to the largest initial ellipse, the two endpoints of the isothermal line segment forming a first vertex and a second vertex of the chromaticity-region quadrilateral, respectively, a point on the largest initial ellipse corresponding to a minimum abscissa of the largest initial ellipse in the uniform chromaticity diagram forming a third vertex of the chromaticity-region quadrilateral, and a point on the largest initial ellipse corresponding to a maximum abscissa of the largest initial ellipse in the uniform chromaticity diagram forming a fourth vertex of the chromaticity-region quadrilateral; and determine the n-step MacAdam ellipse in the chromaticity-region quadrilateral.
