Visual search tasks are mainly test methods of user performances for smartphone displays, which are usually used to assess the subjective quality of the visual display terminal. This study investigated the effect of different smartphone displays on visual search performance. A within-subject factorial design was used in this experiment. The visual search contents were Landolt Ring visual search performance, the search target of which was a ring with a gap in one of the four directions (up, down, right, left). The experiment was carried out in three smartphone displays. The search time and accuracy of each participant were recorded. The difference in search performance and subjective experiences among different smartphone displays was significant. Post hoc comparisons found that the search performance and the subjective experiences under the OLED was significantly better than the other smartphone displays, the low blue light LCD was second and he general LCD was the worst. These results revealed that visual search performance and the subjective experience were sensitive to different smartphones. The obtained results could be a reference to decide the visual search efficiency on different smartphone displays. |
