Paper Abstract

Field-Sequential Color (FSC) displays have been discussed for a long time. Its main concept is to remove a color filter so that we may increase the light transmittance of an LCD panel. However, FSC displays have a major problem: color break-up (CBU). Moreover, it is difficult to quantify the CBU in saccadic eye movements, because the phenomenon occurs as quickly as a flash in saccadic eye movements, and there are individual variations for perceiving the CBU. Some previous studies have presented assessments of saccadic CBU, but not indicated the detection and allowance thresholds of the target size in horizontal saccadic eye movements. Then, we conducted psychophysical experiments based on an FSC display driving with sub-frame frequency of 240Hz-1440Hz (each frame consist of red, green, and blue sub-frames). We employed a simple stimulus for our experiment, a static white bar with variable width. We tasked ten subjects a fixed saccade length of 58.4 visual degrees in horizontal eye movements, and a fixed target luminance of 15.25cd/m2. We examined PEST method to find detection and allowance thresholds of white bar width for saccadic CBU. This paper provides correlations between target sizes and sub-frame frequencies of an FSC display device, and proposes an easy evaluation method of perceiving saccadic CBU on FSC displays.
