Using simulation and human vision evaluation to illustrate why "G-center" pixel unit exhibiting the best image quality on a stripe sub-pixel LCD

In this paper, we study the effects on rendering images with various RGB stripe sub-pixel arrangements. Simulation principle is based on Fourier optics, that is, different RGB sub-pixel arrangements generate different qualitative influence on rendering images due to their different intensity distribution in spatial frequency space. We also executed the human vision evaluation to judge what type of sub-pixel arrangement can render the best image qualities compared with five original photos. Meanwhile, rendering image properties were analyzed with modulation transfer function (MTF). Both simulation and human vision evaluation have proven that it obviously shows that "G-center" sub-pixel arrangements render the best images with lowest color errors and good performance among all stripe sub-pixel arrangements.
