Abstract
The present invention discloses a chromaticity optimization method for a liquid crystal display and the liquid crystal display. Since there are different combinations between liquid crystal panels and backlight units, a cross-matching operation is conducted to get optimized results in matching pairs each made up of one of the liquid crystal panels and one of the backlight units, so that chromaticity coordinates (x, y) at a white point of each assembled liquid crystal display have a tolerance range of ±0.015. This effectively improves chromaticity errors of the assembled liquid crystal display and can be implemented in automated production.
