摘要： A flat panel display includes a four-color conversion unit, a backlight control unit, a backlight module, and a pixel array. The four-color conversion unit provides a first set of four color image signals corresponding to three color image input signals based on a preliminary conversion lookup table and provides corresponding conversion scaling factors. The backlight control unit generates a backlight adjusting factor based on the conversion scaling factors. The backlight module provides a backlight output having an intensity adjusted according to the backlight adjusting factor. The four-color conversion unit further provides a second set of four color image signals corresponding to the three color image input signals based on the backlight adjusting factor. The pixel array displays an image according to the second set of four color image signals and the backlight output.

摘要： A color filter with low color shift is defined by a light leakage spectrum in the dark state. The color filter is disposed between two polarizing plates so as to measure a first spectrum of dark state a(λ), wherein the polarizing directions of the polarizers are orthogonal to each other. A second spectrum of dark state b(λ) while the color filter is removed, and then a ratio spectrum of light leakage intensity I(λ)=(a(λ)/b(λ)) is determined. A maximum value P1 in the ratio spectrum of light leakage intensity is determined in a wavelength region in which the ratio spectrum of light leakage intensity of green photoresist overlaps that of a blue photoresist. A maximum value P2 in the ratio spectrum of light leakage intensity is determined in a wavelength region in which the ratio spectrum of light leakage intensity of red photoresist locates. An average value P1,avg of several ratios of light leakage intensity around the value P1, and an average value P2,avg of several ratios of light leakage intensity around the value P2 are determined. The color filter with low color shift meets the following formula 0.74≦P1,avg/P2,avg≦2.
