In recent times, many accidents have occurred due to challenges in accurately identifying the location of workers, posing a significant societal concern demanding resolution. Therefore, it is essential to develop smart luminescent safety attire to enhance worker visibility in dim environments, thereby curbing accidents. In this study, we propose the utilization of textile-based OLED devices in creating smart luminescent safety clothing, aiming to augment the discernibility of workers over extended distances in low-luminance environments. In view of this, we engineered an attachable textile-based OLED module that balances high luminous efficiency with wearer comfort. Subsequently, a prototype smart luminescent safety clothing was demonstrated, and a performance evaluation was conducted to determine whether any discomfort occurred on wearing it. The fabricated OLED luminous module exhibited high luminance, thus validating the feasibility of creating smart luminescent attire with adequate brightness. Furthermore, there was no significant wearing stress observed, even after wearing it for more than 8 hours, and there was no impediment to various work-related movements. Through this research, we successfully demonstrated OLED based on smart luminescent safety clothing, which has the potential for wide-ranging applications across various industries and occupations, and is expected to play a crucial role in averting safety incidents.

Clothing has a very important role in human life, and it is the most human-friendly platform because humans wear it in almost all the time. In the recent years, smart clothing integrated with various functions is solidifying its position as the core of next-generation Information and Communications Technology(ICT). With this global trend, the smart textiles, textiles embedded with electronic devices that are capable of performing various functions, have been attracting a lot of attention. Therefore, various research activities on the smart textiles are in progress, and the global market outlook for the smart textiles is also showing rapid growth. Among the various smart textile technologies, the textile/fiber-based wearable display has been attracting more attention because it is an essential element for wearers to intuitively control the functions integrated in the smart textiles. This paper provides insightful information and the technological elements of organic light emitting diodes(OLEDs) display, which have been evaluated as the most ideal device for luminescent clothing. Since, OLEDs have many advantages such as light weight, extremely thin thickness and great flexibility, the textile/fiber-based wearable OLEDs can be worn without any inconvenience. In addition, by introducing previous studies on the textile/fiber-based OLED displays, we intend to consider the commercial potential of the textile/fiber-based smart luminescent clothing using the OLED technologies.
