Evaluation of time to visual fatigue for prolonged using a mobile phone

Because the mobile phone becomes cheaper, the Smartphone will be popular in our life in recent years. At present, the AMOLED (Active Matrix Organic Light-Emitting Diode) and LCD (Liquid Crystal Display) are the most common materials used for Smartphone display panels. The AMOLED is the mainstream of Organic Light-Emitting Diode (OLED) technology, which has a faster display than traditional screens, and is characterized by lightweight, thinness, high resolution, energy saving, and flexibility. The brightness and resolution of display panel may influence visual fatigue occurrence time (Wu et al., 2007). However, whether AMOLED leads to visual fatigue more early than the LCD does should be further explored. 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 Smartphone. Furthermore, many studies have discussed the design principle of static information and the evaluation of visual performance (Wu et al., 2007; Wu, 2011), while the visual fatigue of viewing dynamic images seldom discussed. Whether viewing dynamic images is more likely to cause visual fatigue than watching static information has yet to be clarified. Therefore, the purpose of this study was to evaluate time to visual fatigue for prolonged using a mobile phone. This study also conducted an experiment to observe when visual fatigue occurs in viewing static information and dynamic images, respectively.
