Among current true 3D display technologies, multi-layer 3D displays based on the principle of compressive light field have the advantages of high resolution, simple structure and faithful restoration of depth cues, demonstrating enormous research value and application potential. In recent years, multi-layer 3D displays have attracted increasing attention from researchers and some progresses have been made in improving the performance. However, there are still some limitations, such as the color deviation issue which causes unnatural colors of the reconstructed scene. In this paper, we propose using a customized look-up table (LUT) to alleviate the color deviation problem of multi-layer displays. For each of the display layers, we measured the response curves of the RGB channels, respectively, corresponding to different input gray levels. Then we compared them with a commercial standard display, so that we could correct each value within the gray range of the three channels to obtain a target output response, and the corrected values were used to build the look-up table. Using the customized LUT, we successfully achieved correction of color deviation in our multilayer display system. Finally, we demonstrated a 3D scene with natural colors, proving the effectiveness of our method on correcting the color deviation in multi-layer light field displays.
