Abstract

An experiment with EIZO CG 19, DELL 19, IBM 19 and HP 19 LCD was designed and carried out to test the interaction between RGB channels, and then to test the spectral additive property of LCDs. The results show that the interaction between channels is very weak and spectral additivity is held well. This result indicates that the manufacture technology of LCDs is improved greatly. But the computation results of tristimuli addition are not very accurate. A new calculation method based on spectral additivity, in which gamma is fitted by a cubic polynomial in each piece of wavelength, is proposed and discussed. The proposed method is proved simple and very few samples need to measure while the computation precision is very high.
