In order to obtain information anywhere, a pocket-size display shall become the mainstream in the near future. Handheld devices are discussed recently. Because the smart- phone becomes cheaper and cheaper, the smartphone will be popular in our life in recent years. Smartphone display technology have two types, including TFT-LCD and AMOLED. Little studies investigated time to visual fatigue for watching these two display types. Therefore, this study expects to find time to fatigue while using these two display types in order to prevent users from accumulative visual fatigue after prolonged viewing the small size screens. This study explores time to visual fatigue for two stimulus types, dynamic (playing a game) and static (reading an article) stimuli and tries to understand whether these results are different.The maximum time to fatigue are also found here for prolonged viewing the small size screens. The results indicated that when people watch two different smartphone displays, they would have visual fatigue symptoms within 60 minutes. The time to fatigue from TFT-LCD was longer than that of AMOLED. Dynamic stimuli caused longer time to fatigue than static stimulus. The time to fatigue were significant different between the two types of screen. However, the time to fatigue were similar between the dynamic and static stimuli. Because using AMOLED smartphone easily led to visual fatigue, we suggested everyone to use TFT-LCD display for prolonged using smartphone.
