52.5 - A Color Gamut Mapping Method Using an OLED Display Model

In this paper, we introduce how to map the native Organic Light Emitting Diode (OLED) panel's color gamut to the standard gamut (i.e., sRGB or P3). In order to achieve better accuracy and speedy mapping for the overall gamut region, we modeled OLED panel considering IR-drop and Lateral leakage which are unique properties of OLED. In the experiment results, it is confirmed that the native mobile OLED panel was tuned to the standard gamut properly and proposed Color Gamut Mapping (CGM) result had an average distortion less than 0.4 in CIEDE2000. (It almost equals to 0.5 JNCD) In addition, whole calibration procedure can be performed within 1 minute by using proposed method, so that could be applied to individual panel calibration in a factory line.
