Crosstalk characterization of stereoscopic 3D display

Abstract

Most of the stereoscopic displays suffer from crosstalk causing serious fatigue, headache, eyestrain etc. The key issue for the success of stereoscopic 3D display is overcoming the crosstalk. In this study, the degree of crosstalk of stereoscopic 3D display using shutter glasses is measured and the characterization models to predict the output tristimulus values by crosstalk are designed and evaluated. There is more than 90% luminance loss for the 3D viewing condition compared to 2D mode though there is little color gamut change. Because of the crosstalk, the measured color from one view is affected by the colors from the other view. Based on the analysis of measurement data, three different crosstalk characterization models are designed. The Model I assumes that the same portion of the light from one view is leaked into the other view applying the same degree of crosstalk for all the measured data. The Model II assumes the different degree of crosstalk between Red, Green and Blue channels. The Model III applies different degree if crosstalk between red, green and blue primary channels and tristimulus values. The crosstalk characterization models are tested with the primary and secondary color combinations between left and right eye views. The result shows dramatic performance improvement for Model II and Model III compared to Model I.
