Abstract :
Large color gamut can be achieved using multi-primary system. Perceived color varies with different sub-pixel arrangement in multi-primary system. Paired comparison experiment has been carried out to study the influence of sub-pixel arrangement of four-primary system. A novel color conversion method has been put forward to achieve unique control signals and fast color conversion in the multi-primary system. With this novel color conversion method, the displayed images in four-primary system for the experiment were obtained. Results show that difference is not statistically significant between different sub-pixel arrangements and structures. With different additional primary, sub-pixel preference is similar. Influence of image content on the results is also not statistically significant.
