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.
