FPD Grayscale Modulation Based on Human Visual System

In order to meet the requirements of FPD’s development which FPD must process more and more information, a new modulation method is proposed. Firstly, some available modulation technologies are introduced; secondly, the principle of the human visual system is provided so as to describe the grayscale modulation principle of FPD; thirdly, one human visual model is constructed to provide a basis for the grayscale modulation; finally, the grayscale modulation based on human visual system is used in FPD control system, and the experimental results show that this method is able to break the bottleneck of the FPD grayscale modulation.
