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.

摘要： An exemplary method for driving a display device is provided. At least one set of input signals is received. Finding the original signals being the same with the input signals in the signal transforming table is executed. The pixel driving signals is outputted. If at least one of the found second and third original signals is equal to zero, and the found first original signal is equal to neither zero nor maximal gray scale, at least one of the outputted second and third sub-pixel driving signals, and the outputted fourth sub-pixel driving signal are equal to zero.
