Abstract
In this paper, we introduce a new method to measure the visibility of a metal- mesh ITO-replacement touch panels. The reason why we have developed this system is to clear up the ambiguity of the visibility estimation or readability property of the metal mesh electrodes in touch sensors. The interference between screen pixels and designed parameters of metal mesh such as pitch, width of electrode lines and the angle of mesh pattern causes serious image quality deterioration. Using this developed objective system one can derive not only moiré value to classify the visibility level but also moiré properties such as frequency and amplitude exactly.
