P‐14.19: Research and Optimization on Eye‐Injury Issues of OLED Screens

In the contemporary digital era, a wide array of electronic devices have become an integral part of people's daily lives. From mobile phones and tablets to laptops and monitors, individuals spend substantial amounts of time gazing at the screens of these devices. Among them, Organic Light ‐ Emitting Diode (OLED) screens have assumed a significant position within the field of electronic display, owing to their remarkable advantages such as high contrast ratio, wide viewing angle, thinness, lightness, and bendability, which are conferred by their self ‐ emissive characteristics. They are extensively applied in various products, including smartphones and televisions. Nevertheless, with the increasing prevalence of OLED screens, the issue of eye protection has gradually drawn attention. Some OLED screens exhibit screen flickering at low luminance levels, which may give rise to discomfort symptoms such as visual fatigue, dry eyes, and headaches. This discomfort is particularly pronounced when used in nocturnal or low ‐ light environments. Consequently, enhancing the eye ‐ protection performance of OLED screens holds great practical significance. This thesis focuses on frequency switching and flicker phenomena, adopting a combined approach of subjective and objective methods to compare the display quality of two groups of screens and analyze their impacts on vision..
