As one of display devices, HUD is mostly used for vehicle navigation display. Now the table-HUD for vision protection is proposed. Through a variety of statistical analysis methods, the influence of different display devices, different types of experiments, different experiment sequences and different objective conditions of the subjects has been studied on the experimental results. It's necessary to evaluate the visual perception and visual comfort of the subjects through subjective and objective evaluation methods. In this paper, three groups of experiments are designed, which are video viewing group, character comparison group and visual task group. The statistical analysis tool SPSS was used to process the experimental data, and the experimental results showed that visual fatigue of different display devices increased with the increase of time. Results also showed that table-HUD was less likely to cause visual fatigue than other display terminals. Experiment sequence and the period of the experiment don't have significant influence on the visual perception and visual comfort of the subjects. Compared with the inter-group experiment and the intra-group experiment, in different groups of experiments, the visual fatigue of subjects in character comparison group was the highest, followed by video viewing group.
