Three-dimensional (3D) stereoscopic display is a promising direction of display technology development, and color asymmetry of left and right eye views is a common phenomenon in stereoscopic 3D displays, which can cause visual discomfort. Under the 3D display, the study of binocular fusion of asymmetric colors is an extension and supplement of traditional color vision research, which has a certain scientific significance to understanding the process and mechanism of visual information processing in the human visual system as well as has application value to solve the problem of visual discomfort in existing stereoscopic display technology. In this study, the relevant literature on binocular color fusion was sorted, and the research status of binocular color fusion was summarized from three aspects: binocular color fusion, the interaction between color and stereo fusions, and the influence of binocular color fusion on the visual comfort of 3D displays. We highlight that the interaction mechanism of binocular color fusion and stereo fusion is still uncleart, and the research results stay on the phenomenon description, lacking quantitative experimental data to establish a color fusion model. We infer that binocular color asymmetry affects the visual comfort of 3D displays. In addition, 3D display-based image enhancement may become a research hotspot in the future.
