Abstract
Most display characterization methods, such as the gain-offset-gamma (GOG) model and S-curve model, generally assume that displays have two fundamental characteristics, channel -chromaticity-constancy and channel-independence. However, these assumptions are not so applicable in the case of liquid crystal (LC)-based mobile displays. Accordingly, modifications are required to enable the application of conventional display characterization methods to mobile displays. Therefore, this study proposes the modeling of distinct EOTFs in terms of the X, Y, and Z values for each channel to consider the differences among the EOTFs resulting from channel-chromaticity-inconstancy. In addition, to overcome the poor additivity property among the channels due to channel-interaction, the proposed method also models and uses the EOTFs of the X, Y, and Z values for the inter-channel components cyan, magenta, yellow, and gray Experimental results confirm that the mobile display color values predicted by the proposed characterization method are more accurate than those predicted by other characterization methods due to considering the channel-chromaticity-inconstancy and/or channel-dependence of the display.
